Doosan introduces new crawler excavators with improved arm and bucket forces, operator control and fuel efficiency

Doosan introduces two new crawler excavators — the DX63-3 compact conventional tail swing and the DX85R-3 reduced tail swing excavator — replacing the DX60R and DX80R models, respectively. These new models are an excellent combination of power, operator control and fuel efficiency, for improved productivity.

The 6.3-metric-ton DX63-3 and 8.5-metric-ton DX85R-3 have a Tier 4 compliant diesel engine with a high-pressure common rail fuel injection system, which provides increased torque and efficient fuel consumption. Both excavators utilize a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), which help reduce emissions to meet Tier 4 air quality requirements.

New features• Fingertip boom swing and auxiliary hydraulic

controls, including variable flow control and detent (continuous) flow mode, improve multi-function capabilities and free up cab floor space

• Independent boom swing control on the joysticks helps operators more easily position the excavators for offset digging

• Auto-shift drive shifts the excavators out of high range or low range and back automatically

• A standard travel motion alarm

Improved digging and liftingThe DX85R-3’s bucket force has increased for improved productivity when excavating or trenching with an impressive 14,509 pounds-force of bucket breakout force — an 18 percent increase over its predecessor for class-leading productivity. The DX63-3 and DX85R-3 offer a maximum dig depth of 13 feet 6 inches and 15 feet 6 inches, respectively.

The DX63-3’s upper structure is shifted rearward on the undercarriage to increase efficiency. Its 11.6 inches of tail swing overhang provides best-in-class over-the-side lifting performance, without increasing the machine’s overall weight. The DX85R-3’s minimal 5.9 inches of tail overhang allows it to work in space-restricted

environments and next to buildings.

fuel level, coolant temperature, day/time, throttle position and engine rpm. Operators can select auxiliary hydraulic flow modes and rates from the panel. For increased security, an integrated password protection system may be used.

Improved grading and levelingAvailable for the first time on Doosan excavators in these size classes, the blade float feature provides operators the versatility to smoothly grade, level or backfill material. The blade height for the DX63-3 has been increased to 16.1 inches — a 21 percent increase compared to the previous model — for better grading and leveling.

Uptime protectionNew boom cylinder guards provide improved uptime protection for DX63-3 and DX85R-3 owners, protecting the cylinder when the excavator is digging. Enhanced access to service areas makes performing routine checks and adding fluids easier. This includes the cab’s ability to be tilted forward to increase access to major components.

BRINGING MORE MUSCLE TO THE FORESTHeavy-duty Doosan DX300LL-3 log loader offers greater productivity, reliability and comfort

For powerful and precise performance, the Doosan DX300LL-3 log loader takes all-day forestry work to a new level. The log loader features a fully guarded, heavy-duty undercarriage and upper structure that is designed specifically for picking, moving and placing your heaviest timber loads in the most challenging operating conditions.

For a more durable construction, the DX300LL-3 is equipped with a high-walker undercarriage design. Its tracks feature heavy-duty links with double grouser shoes and full-length track guiding guards. The DX300LL-3 also has durable top rollers with special clean-out brackets.

The DX300LL-3 complies with iT4 emission standards and regulations, using a three-fold systems approach: cooled exhaust gas recirculation (CEGR), a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). This engine optimization also delivers increased horsepower and torque, for improved operating performance and productivity.

The high-pressure common rail fuel-injected engine teams with the Electronic Power Optimizing System (EPOS) to deliver optimum power and fuel efficiency to forestry projects. The EPOS also provides four power modes, auto idle and machine diagnostics. Additional features that increase Doosan customer efficiency include an easy-to-read display monitor and precise controls.

Upper structureThe log loader’s upper structure offers mainframe reinforcement, full under-house plate guarding, integral catwalks, heavy-duty side doors with guarding over the hydraulic pump and cooling system access doors, and undercarriage guarding. Its cab features a 4-foot riser with hydraulic tilt for transport.

The DX300LL-3 log loader has a larger cabin that combines superior comfort, good visibility, low noise levels and a roomy environment. Operators can work naturally with the standard heated air suspension seat and a large door opening for easy cab entry and exit. The high-performance air conditioning system offers adjustable airflow and five operating modes to keep operators cool throughout the workday.

Easy-to-operate joystick controls facilitate precise machine movements. A multi-function color LCD monitor displays a variety of machine

information, including operation history, flow-rate control and filter/oil information. In addition, the sound-suppressed cab keeps machine noise low to reduce fatigue.

Extended maintenance intervals and easy access to service points increase machine uptime and productivity. Examples include:

• centralized grease points

• wide side-access doors for cleaning the cooling system

• boom pivot bushings with increased greasing intervals

Peitzmeier Demolition

DOOSANHEAVY HITTERS make easy work of

DEMOLITIONThree Doosan excavators ignite success for young demolition company

continued on page 8

Starting a demolition company was something that Mark Peitzmeier of Omaha, Neb., had wanted to do for many years. After his three daughters graduated from college, he decided it was “now or never.” After just 18 months in business, Peitzmeier Demolition and Concrete Cutting has a growing list of confirmed projects, expanding employee base and need for Doosan heavy equipment.

Prior to starting his own company, Peitzmeier worked for a construction company in the Omaha area. He leveraged nearly 30 years of knowledge of the construction industry when he started his demolition and concrete cutting business.

“We started with some smaller jobs and then we landed a demolition job with Kiewit,” Peitzmeier says, “and that really got our foot in the door. That is when we purchased our first piece of Doosan equipment.”Two Doosan excavators equipped with clamps sort demolition debris at the jobsite.

Preparing for new outdoor outlet mallThe Kiewit project that Peitzmeier is referring to is demolition of the Nebraska Crossing outlet mall, from March through April 2013, to make way for a new outlet mall in Gretna, Neb., that opened in fall 2013. The new 350,000-square-foot, $87 million outlet mall is called Smart Outlets at Nebraska Crossing. Peitzmeier was selected as a subcontractor to demolish the outlet mall, and had just eight weeks to complete the work. Peitzmeier says his company finished the job early, in about six weeks, even with an exceptionally wet early spring.

Two developers, Century Development and OTB Destination LLC, announced a proposal in early 2013 to demolish the current structure and construct a new outlet mall that would feature new stores and more recognizable names, with as many as 60 tenants. Construction crews arrived shortly after the proposal was approved by the City of Gretna, and Peitzmeier and crews started their demolition efforts.

Diverse equipment for demoPeitzmeier, his General Superintendent Ben Ruthven and crews utilized both compact and heavy equipment to efficiently demolish the 170,000-square-foot mall, beginning March 1.

Ruthven says crews started the project by stripping the facade from the front of the building, working from the west end of the structure eastward. He said the company then sent in its skid-steer loaders equipped with industrial grapples and general purpose buckets to gut the inside, down to the block walls and steel columns and trusses in the roof.

Peitzmeier owns five Bobcat® skid-steer loaders for interior demolition tasks. He says they brought the material out of the building with industrial grapple attachments and loaded it into containers for removal and offsite processing.

“We try to recycle as much as we can — all the copper, wiring and steel. And the concrete and masonry, we keep clean and take it to get recycled and crushed,” he says.

Once the compact equipment had done its job inside, Peitzmeier transitioned to three Doosan crawler excavators and attachments for the heavy-duty work.

“We came in with the Doosan excavators and started from the front, working our way to the back, ripping the roof off, leaving just a couple of main trusses,” Ruthven says. “Then we ripped the main trusses, tipped the walls over and pulled up the slabs.”

Doosan excavator trioFor a project of this size, Peitzmeier went to a familiar name, a company he had worked with for more than 10 years, for some guidance for heavy equipment selection — his compact equipment dealer in Omaha. Dave Goodsell and Scott Gerdes at Bobcat of Omaha, an authorized Doosan heavy equipment continued on page 10

Doosan excavator advantagesWorking in demolition is one of the most demanding and difficult applications for heavy equipment. That’s why customers like Mark Peitzmeier (pictured below) need dependable and productive equipment to stay on schedule. Here’s what Peitzmeier had to say about the Doosan excavator advantages compared to other brands.

Fuel consumption

In comparing crawler excavators and their fuel consumption from his previous employer to his Doosan excavators, Mark Peitzmeier says his Doosan crawler excavators are much more fuel-efficient, which contributes to his bottom line.

“The company that I used to work for had a different brand of crawler excavators, and we were burning up about twice as much fuel as we do with the Doosan excavators,” he says. “When you do the math, it starts to add up to a lot of savings.”

Dealer support

In addition to their fuel savings, Peitzmeier and General Superintendent Ben Ruthven agree that the Doosan excavators are easy to maintain and have readily available parts and service from their local Doosan dealer. They say their local dealer is easily accessible, has readily available parts and well-trained mechanics to ensure their demolition equipment is ready for work. Ruthven says they have very little downtime, thanks to the durability of the Doosan equipment.

Operator comfort

Working as many as 12 hours a day in the excavator cab, Ruthven says his operators enjoy the comfortable operating station and good all-around visibility. He says his employees appreciate the cab’s heat and air conditioning for year-round comfort, the radio and the rearview camera to see what’s behind them, especially when they’re working on projects like the outlet mall demolition project.

The DX180LC has plenty of power for the type of work that we do. We used it to pull out some

pretty good-sized footings and didn’t have any trouble at all.

With a clamp and bucket, the DX140LCR excavator sorts through demolition

debris before loading it into containers to be hauled away.

dealer, suggested three Doosan crawler excavators: DX140LCR, DX235LCR and DX180LC. The 14-metric-ton, 109-horsepower DX140LCR and the 24-metric-ton, 173-horsepower DX235LCR are reduced tail swing models, which was an added benefit for the job that required working in some limited-space areas.

Ruthven says the size of the Doosan DX140LCR and DX235LCR excavators made them a good fit for the demolition project.

“The best thing about the Doosan excavators is their reduced tail swing,” he says.

“When we first started this project, everything was so tight. We could squeeze between buildings and didn’t worry about the counterweight hitting something. That was a big plus for the two machines. The camera on the back of the excavator allowed the operator to see what was behind him and provided good all-around visibility. You need good visibility when you’re working in a situation like this. You’re working right next to other structures and other machines.”

Sorting demolition debris and recyclable materials helps minimize waste that goes to the landfill, something that Peitzmeier says has changed since he started. He says more and more demolition debris is recycled than ever before.

“The DX140LCR processed and sorted a lot of the material and did some of the concrete slab removal,” Peitzmeier says. “We like to separate everything because it works out better economically for us. The DX235LCR is a workhorse here. It’s nice for doing the big stuff, like tearing the roof off.”

A third excavator, the 18-metric-ton, 125-horsepower DX180LC, was operated to pull up footings and remove old sewer systems at the site.

“The DX180LC has plenty of power for the type of work that we do,” Peitzmeier says. “We used it to pull out some pretty good-sized footings and didn’t have any trouble at all.”

Attachments aid sorting taskA combination of buckets and hydraulic clamps, equipped with a two-way hydraulic kit on the Doosan DX140LCR and DX235LCR excavators, enabled operators to easily grab, lift, sort and load recyclable material into containers, which were then hauled away for recycling. With the clamp’s serrated edges holding firmly onto the demolition material, the operator precisely loaded it into containers and maximized the container space.

“It’s so precise that you can pick a stud out of a pile with the hydraulic clamp,” Ruthven says, “and it makes our job a lot easier than it used to be.”

By early April, crews were tearing down the final portion of the outlet mall, finishing ahead of schedule.

“We were able to give Keiwit the startup for the dirt work about four days early,” Peitzmeier says. “Kiewit got started on it ahead of schedule. This project turned out to be a nice job for us to get our foot in the door and work with Kiewit, being the biggest company around, of course. I told the guys, ‘if we don’t hit these dates, we won’t be working for Kiewit again,’ so we were all motivated. Demolition is our job and our livelihood, and we were going to make them happy, no matter how long we had to work. We were going to make the dates they wanted.”

John Anderson Construction

Doosan equipment helps Pennsylvania contractor survive the

Great Recession as he finds new revenue sources in Marcellus Shale

pipeline development

Being able to adapt to changing economic conditions and evolve into new construction ventures is what has helped John Anderson (pictured left) keep his company going.

The owner of John Anderson Construction knows how to take existing heavy construction equipment and leverage it to find new opportunities, even in a new and emerging marketplace. The company is headquartered in Warren, Pa. (pop. 9,623), which is located in northern Pennsylvania and sits next to the Allegheny National Forest and Complanter State Forest. It has grown to include four divisions: earthwork, concrete, pipeline and facilities.

From corporate world to constructionFor the past 28 years, Anderson has worked in the construction industry. He left the corporate world in 1985 — previously working as a securities advisor — and began working for a local concrete contractor. Anderson started his own company in 1989 and specialized in residential concrete projects, eventually expanding into commercial concrete jobs. Over time, he transitioned his company’s services from concrete work to include excavating, which led to becoming a site contractor, while still offering concrete services for civil projects. Completed projects include several concrete projects of 2,000 cubic yards and a foundation of 2,400 cubic yards.

NEW OPPORTUNITIES EMERGE IN

ENERGY EXPLORATION

continued on page 12

In addition, his earthmoving equipment was responsible for road building, rock demolition and moving thousands of yards of dirt.

The next step was getting more involved in excavating for underground utilities and site development. In 2008, just as the economy was in the middle of the longest recessionary period since the Great Depression, Anderson discovered a new opportunity — excavating for natural gas pipelines.

“We’ve been fortunate to find ourselves in the midst of the Marcellus Shale boom,” Anderson says. “We’ve positioned ourselves in the transmission pipeline and compressor station business, and it’s really helped us grow.

“It’s been an evolution. You keep pushing the boundaries of what you can do. I’ve never said ‘no’ to an opportunity without at least looking at it. Then, as we branched out and

continued to expand our comfort zone, we hired people who had knowledge in some areas where we were going.”

The company has installed miles of steel and FlexSteel™ transmission pipe (steel-reinforced spooled pipe), up to 36 inches in diameter, and completed several compressor installations. Pipeline companies install compressor stations — a facility that helps transport natural gas from one location to another — typically every 40 to 100 miles to ensure that the natural gas remains appropriately pressurized.

U.S. energy production continues to rise, thanks in part to the Bakken (crude oil) formation in western North Dakota and eastern Montana, and the Marcellus formation, which exists in the Appalachian Basin across the eastern United States and contains previously untouched natural gas reserves. Pipeline projects in central and western Pennsylvania, eastern Ohio and northern West Virginia account for approximately 75 percent of Anderson’s business.

“Much of what we do is what is called a gathering system and mid-stream work,” he says. “We also do some transmission line work.”

The gathering system, according to www.naturalgas.org, consists of low-pressure, small-diameter pipelines that transport raw natural gas from the wellheads to the processing plant.

In May 2013, Anderson and his employees started on a new four-month, three-mile pipeline project for Natural Fuel Gas

Marcellus Shale area



Company. The corporation is based in Williamsville, N.Y., and is a publicly traded firm that specializes in four operating segments: exploration and production, pipeline and storage, utility and energy marketing.

Anderson called on his Doosan crawler excavators to perform the pipeline installation project. The excavators were paired with a 36- or 48-inch-wide heavy-duty trenching bucket. Anderson’s DX350LC-3 with a 48-inch Doosan trenching bucket has a heaped capacity of 1.96 cubic yards (52.92 cubic feet) of material. The Doosan excavators dug 5- to 9-foot trenches for the pipeline, says Anderson. (NOTE: The “dash 3” in the model number represents the newest generation of Doosan crawler excavators, with an interim Tier 4 diesel engine and performance and operator comfort enhancements.)

Right-sized equipmentFor the past 12 years, Anderson purchased Doosan hydraulic crawler excavators — 10 to be exact — from area dealers in New York and Pennsylvania. His first Doosan excavator was a 17-metric-ton machine purchased in 2001, a machine that he still owns and

operates today, and has close to 10,000 hours. As his business grew, Anderson added more Doosan excavators, including an DX180LC, two DX225LCs, two DX255LC models, and eventually worked up to a 30-metric-ton DX300LC model that he purchased from authorized Doosan dealer Best Line Equipment in Harrisburg, Pa.

“I needed the 300 (DX300LC) that Best Line Equipment had,” he says, “so I called the dealer and I had it on my job within a day or two.” Anderson added a second DX300LC, and in fall 2012, he purchased a DX235LCR and a DX350LC-3.

Having a variety of Doosan crawler excavators suits Anderson and his operators well, especially when they’re working on pipeline developments, Anderson says. He explains that the Doosan DX225LC and DX300LC

models — 22.5 and 30 metric tons, respectively — are the right size of excavators for trenching, but the model that he likes best is the DX235LCR because of its reduced tail swing. The 173-horsepower excavator has a maximum dig depth of 21 feet 11 inches and a maximum reach of 31 feet 7 inches.

“The DX235LCR cuts down on the chance of operator error and damaging the machine,” Anderson says. “Even though we’re working in an open area, it’s a little bit deceiving because if we’re putting in a couple miles of pipe, we probably only have 50 to 60 feet of width to work in. The operators can’t get off the permitted right-of-way of 50 feet.”

It is common for Anderson to have multiple Doosan excavators working in tandem on a pipeline project, digging from 5

to 21 feet with a trenching bucket, working close together, and it’s another reason why Anderson appreciates the reduced tail swing of his DX235LCR. In addition to excavating, Anderson’s operators use straps and a Doosan DX350LC-3 excavator to lift and place pipe as large as 36 inches and weighing up to six metric tons. Having good visibility from the cab to the work area is critical for the operator’s success.


DL250 at gravel pitsIn keeping with his preference for Doosan equipment, John Anderson has a Doosan DL250 wheel loader for use at the company’s gravel pits (facilities division). Locations in Warren and Russell, Pa., provide the following materials to local customers:

• Screened topsoil• Screened bank run• Crushed bank• Crushed concrete• No. 3 stone

• No. 4 rip rap• 2B gravel• 2B limestone• Cold patch• Fill dirt

• Large rock• Pea stone• Sand

The DX235LCR cuts down on the chance of operator error and damaging the machine. Even though we’re working in an open area, it’s a little bit deceiving because if we’re putting in a couple miles of pipe, we probably only have 50 to 60 feet of width to work in. The operators can’t get off the permitted right-of-way of 50 feet.

Anderson says he rates the visibility from the Doosan excavator cab as “excellent.”

The DX350LC-3 is one of the newest generation of Doosan excavators and features a larger cab space to accommodate operators and keep them comfortable. Anderson says the new DX350LC-3 is comfortable to operate, but he also gives credit to the design of his older models, saying Doosan excavator cabs have always been friendly to operators.

In addition to his Doosan heavy construction equipment, he also owns Bobcat® skid-steer loaders and a hydraulic mini-excavator for projects that require a smaller machine to work in confined or limited-access areas.

When asked what Anderson enjoys most about his line of work, he says, “Meeting and working with people from different backgrounds. I feel like I’ve been very fortunate to be in a situation where I’m always learning and being exposed to new things. I’ve been fortunate to be associated with a lot of good people who work for me and who we’ve worked for.”

DeVere Construction

Doosan heavy equipment helps contractor overcome highway construction challenges, contribute toward success with many tough construction projects in the Tar Heel state

As summer turned to fall in North Carolina, the days got shorter and cooler, but for the crew working on building the Highway 421 Sanford bypass, there was little time to enjoy the autumn season.

Mike Evans and Jeff Cromer h a d t h e c o f f e e r e a d y. Kleingartner began the day with a detailed walk-around of the DX350LC-3, pointing out the design highlights and features of the new 77,000-pound model.

With the DX350LC-3, said Kleingartner, Doosan has advanced its 35-metric-ton model to Tier 4-Interim status, retaining the DX350LC Tier-3 model’s common-rail fuel system and adding a variable-geometry turbocharger, diesel oxidation catalyst, diesel particulate filter, and a cooled-exhaust-gas-recirculation system. Although developing the same 271 net horsepower as its predecessor from the 8-liter DL08K Doosan engine, the new model does so at a lower, fuel-saving speed: 1,800 versus 1,900 rpm.

Along with equipping the D X 3 5 0 L C - 3 w i t h n e w emissions-related technology, Doosan also has essentially redesigned the machine’s hydraulic systems, using hydraulic motors of greater displacement and greater torque in the swing and propel s y s t e m s , b u t f o c u s i n g p r i m a r i l y o n t h e n e w D-ECOPOWER electronic control system, which, says the company, can y ie ld productivity gains of more than 25 percent and fuel

savings on the order of 12 percent, compared with its predecessor.

Kleingartner explained that when designing the new implement hydraulic system, Doosan engineers combined aspects of both open- and closed-center systems, with the objective of incorporating the best attributes of both for optimum power, control and efficiency.

“The system uses much of the oil typically returned to the reservoir,” he said. “Based on electronic pilot signals from the joysticks, the system determines how much oil to direct to the positive side of the system for increasing overall flow. That’s oil the pump doesn’t have to produce, so the load on the pump and engine is reduced—along with fuel consumption.”

The DX350LC-3 also has four power modes available in its Electronic Power Optimizing System—economy, standard, power and power-plus—and allows an increase in main pressure, to 5,512 psi, via its one-touch power-boost button on the right joystick. Complementing the power modes are four work modes—digging, lifting, breaker (one-way auxiliary flow) and shear (optional two-way auxiliary flow). Pressure and flow can be c o n f i g u r e d t h r o u g h t h e m o n i t o r f o r 10 attachments, five one-way and five two-way. In addition, said Kleingartner, single- or dual-pump flow is programmable, depending on application demands.

“The ability to program attachments would be really helpful on a demolition site,” said Local 150’s Poyner, “where you might frequently be changing between a hammer and a shear.”

Another substantial design change is the new model’s revamped cooling system. The hydraulic-oil cooler and the radiator, which were stacked in the predecessor model and shared a fan, now occupy separate compartments, and each uses a dedicated fan (an electric-clutch type for the radiator and a hydraulically driven type for the oil cooler), allowing independent temperature control for the two systems.

These changes, said Kleingartner, give the new machine a 15-percent boost in overall cooling capacity, allowing the use of smaller components and, in conjunction with a dedicated fuel cooler, improving the combustion process.

Also new for the DX350LC-3 is an optional “intelligent floating boom” that can be set to allow the boom to move freely up and down with the contours of the ground when grading, or can be set to move freely only downward to maintain optimum pressure on hydraulic hammers. A reset button allows momentarily disengaging the float mode and enabling hydraulic flow.

Although major structures (mainframes, carbody and track frames) are little changed from the predecessor model, the DX350LC-3 does incorporate added internal gussets in the digging arms (two are available at 10.5 and 13.0 feet). Like its predecessor, said Kleingartner, the new model uses high-strength castings at all pivots in the digging mechanism, and at the lift-cylinder-to-boom connections, the casting extends across the width of the boom.

After spending the better part of the day using the DX350LC-3 for trenching, truck loading, and lifting a 15,000-pound section of a manhole box, the overall con sensus among the Local 150 operators was that the newDoosan was powerful, quiet and smooth.

Views from the seat“It’s smooth, it’s responsive, it’s strong,” said Cromer.

“The bucket was a bit small [1.4 cubic yards, the only bucket available from the local dealer], but judging from the machine’s performance, it would be fine with a larger bucket. You’d be able to easily carry a grade.”

Cromer also noted that the DX350LC-3’s swing movement was slightly different than that of most excavators: “The swing seems to have a gradual braking action. It’s a nice feature. You don’t have to be as cautious with it, because on most machines it’s going to come to a screeching halt, so you can’t come around running too hot, so to speak. But on this one you can, because it’s got that gradual drag that doesn’t give you a jolt.”

Kleingartner explained that the swing system is designed to provide a cushioned stop in the interest of operator comfort.

“I like it,” said Evans. “It’s a nice machine, very quiet, smooth to operate. I didn’t experiment with the power modes—just throttled up and went to work. It’s got power—and a nice radio. Running with the door shut, there’s hardly any noise.”

Cromer added that even bystander noise seemed to be reduced. Kleingartner told us that contributing to the machine’s reduced sound levels—whether inside or outside the cab—is the machine’s recently refined common-rail fuel system, which, he said, runs with considerably less noise than conventional fuel systems.

Thinking about Evans’ comment about not experimenting with the power modes, we asked Poyner and Cromer if they had tried them. They told us that power modes are pretty much lost on most operators when they’re trenching or loading trucks.

“Honestly,” said Poyner, “I’d never put this machine in anything but power-plus. I’d never use the standard or economy modes. As an operator, I’m not paying for fuel, so economy isn’t much my concern—my concern is production. I tried the boost button in the standard mode, and it made a difference, but not as much as when you’re in power-plus. Power-plus with boost—now you’ve got something. I sunk it into that thick, wet clay, and no problems.”

Cromer echoed Poyner’s opinion: “Realistically, you’re not going to run in anything but full speed. Most of the contractors I’ve worked for, if they catch you running in anything but that, they’ll chew you out. They’re just looking for dirt coming out of the hole.”

One feature all the operators liked was the ability to switch between the ISO and “backhoe” control pattern, but all agreed that the feature would be further enhanced if the pattern could be switched from the cab. (Turning an adjusting screw in a small valve positioned in the left-front compartment changes the pattern.)

“With the number of students we train, the ability to switch patterns is important,” said Evans, “because you always want them running with controls that are comfortable. When you have to think about what you’re doing, you’re going to get into trouble—it has to be

Relocating the radiator and hydraulic-oil cooler gives the new DX350LC-3 a sizeable increase in cooling capacity (left), and relocating all filters to the pump compartment simplifies routine maintenance.

intuitive. Yes, it would be more convenient to have a switch in the cab, but at least the pattern changer is there, and it’s really not all that difficult to use.”

All agreed, as well, that the DX350LC-3’s backup camera was an excellent feature, displaying crisp images on the machine’s 7-inch color monitor.

“All-around visibility is very good,” said Cromer, “and I like the backup camera. That’s usually where the foreman likes to park his truck—right in your blind spot.”

The monitor also digitally displays what appear to be analog gauges and serves as an intuitive interface for setting machine operating parameters, such as pressure and flow for various attachments.

“The controls were self-explanatory,” said Poyner, “and the display was easy to use.”

Evans also mentioned other features that he thought important: “I like the rotary switch for the battery disconnect in the back compartment. If it’s a key-type switch, you usually end up losing the key. And the tracks would be easy to clean, because the undercarriage is up high enough and the track frames are sloped.”

Cromer commented on the machine’s lifting ability, saying it was “hydraulically strong and smooth.” He added, though, that he preferred lifting in the power modes.

Poyner said he found the cab roomy and comfortable—plenty of leg room—and the “creature features” welcome. But he’d change a few items if he could.

“I’d change the location of the radio—there’s a space under the left armrest to accommodate it, and I’d move the coffee holder to the right front, under the monitor,” he said. “But, remember, this is typical operator talk when you don’t have anything else to cry about.”

But Poyner did bring up a serious issue: “All I’ve seen are smaller Doosan machines, so with a machine this size, would I have a problem getting parts?”

Kleingartner said that Doosan has had a parts-distribution facility in North American since the late 1980s, and that the facility recently moved from Suwanee, Ga., to Chicago.

“Doosan also has a 48-hour parts guarantee,” he said, “which means that we’ll ship any machine-debilitating part in 48 hours or less, and if for some reason the company can’t meet that commitment, we pay for a rental machine.”

“Important in today’s market,” said Poyner. See our v ideo repor t on the DX350LC-3 a t ConstructionEquipment.com/DX350.

Doosan heavy equipment helps contractor overcome highway construction challenges, contribute toward success with many tough construction projects in the Tar Heel state

As summer turned to fall in North Carolina, the days got shorter and cooler, but for the crew working on building the Highway 421 Sanford bypass, there was little time to enjoy the autumn season.

Crews worked on the job, seven days a week, from dawn to dusk, according to Dustin Crittenden, DeVere corporate fleet manager. “At times we even worked around the clock.”

Battling rain delays throughout the project, the company was challenged by a very rocky terrain that added to the difficulty of moving 1.3 million cubic yards of unclassified excavation material in order to complete the final portion of the bypass.

“This was probably as difficult an environment as you can put your equipment through,” Crittenden says.

Business expands in N.C.DeVere Construction, a four-decade-old company headquartered in Alpena, Mich., is known for bringing comprehensive construction management, general contracting and design/build services to a wide range of projects. The firm saw opportunity in North Carolina in the late 1990s when Raleigh was identified as a growth area. Initially most of the work

consisted of school construction. About three years ago, as much of that state money dried up, the company switched gears to take advantage of federal stimulus funds.

In August 2002, construction began on a 13.5-mile bypass around Sanford.

The $30 million project has been challenging for the firm’s 80 on-site employees and their equipment.

“The rocky ground just tears up the machines,” Crittenden says. “Once you rip through or blast the rock, it breaks into a powder that wreaks havoc on fuel filters and air filters. Our Doosan machines on the job have been very durable. One of the excavators, a rented DX350LC, has more than 5,000 hours of use and is still performing very well.”

The first piece of Doosan equipment to arrive at the Sanford bypass project was a 160-horsepower DL200TC (tool carrier) wheel loader. After almost 40 years in the construction business (25 as a manager or superintendent), DeVere Construction Assistant Project Manager Randy Perry has had plenty of experience with all of the major brands of equipment; however, this was his first experience with a Doosan product.

“I was impressed,” Perry says of Doosan equipment. “We use it with both bucket and pallet forks to carry materials for our pipe and grading crews. The operators, who put in some very long hours, report that the cab is very comfortable and offers good all-around visibility. The DL200 made me a firm believer in Doosan equipment.”

Next came the DX350LC, which further reinforced his favorable opinion of the Doosan brand. The 281-horsepower crawler excavator is operated with a hydraulic breaker

to deliver high-impact production through exceptionally tough rock. It’s also used with a bucket to load trucks.

And when it comes to trucks, Perry has also been pleased with the performance of the

DA30 articulated dump truck, the third Doosan product on the Sanford jobsite.

“It is very mobile and agile, the operators like the comfortable cab, maintenance is simple and when working in wet clay, it displays very good traction,” he says. “The truck was used

to haul out unclassified material, typically 22 to 26 loads per shift. Most hauls are about one-and-a-quarter miles. The longest roundtrip is two-and-a-half miles.”

Even after being involved in construction for more than four decades, Perry continues to learn things on each job. One of his takeaways from the Sanford bypass project is a newfound appreciation for Doosan heavy equipment. “I’m a firm believer in what Doosan is doing,” he says.

Well-researchedThe machines used on the Sanford project, just like all of DeVere’s equipment purchases and rental choices, are based on thorough research.

“That’s a big part of my job,” Crittenden says. “I compare every tidbit of information I can get my hands on when it comes to choosing one model over other similar machines. I have a spreadsheet showing how all our equipment performed over the last couple of years, right down to value per hour at each location. This is critical when evaluating products.”

First impressionTwo years ago, the company needed to rent a large excavator for a job in


Articulated dump truck impresses on bypass projectOne of the impressive pieces of construction equipment working on the Sanford bypass job, according to Randy Perry, assistant project manager for DeVere Construction, was the Doosan DA30 articulated dump truck.

Powered by a 5-cylinder, iT4 compliant 365-net-horsepower diesel engine, the redesigned truck is already gaining attention for its increased engine power and torque, lower fuel consumption, enhanced operator comfort and faster travel speeds (top speed of 34.2 mph).

“The DA30 strengthened my belief that Doosan is on the right track,” Perry concludes.

I work with many different equipment vendors throughout North Carolina, and of course they all claim their products are the best. However, based on our experience the past two years, I can say to them that’s not the case because when I compare what their machine can do and what my Doosan machine can accomplish, mine is much better.

North Carolina. H&E Equipment Services, the Doosan dealer in the Raleigh area, had just taken delivery of a heavy-duty, 48-metric-ton DX480LC. “We were quickly impressed with its power and speed,” Crittenden says. “When we compared it to similar competitive models, the superior load-out time of the Doosan product really stood out.”

DeVere Construction’s good experience with the Doosan DX480LC, which is now on its third jobsite, led the company to rent and purchase additional crawler excavators, in addition to Doosan wheel loaders and articulated dump trucks. “As our employees began to use more Doosan products, the reaction was, ‘Wow, these are really nice machines,’” Crittenden says. “Then the job superintendents started requesting more Doosan equipment because they performed so well. Since then, with every piece of equipment that has hit a jobsite, we have learned more and more what a good product Doosan makes.”

After using the Doosan excavators and loaders for a couple of years, Crittenden was asked how the data accumulated on the machines compared with similar products from other manufacturers. “The simple answer,” he says, “I just purchased six more pieces of Doosan equipment!”

Fuel efficiencyMore specifically, the excavators rate high on fuel efficiency. “I am really impressed on how far we can make a tank of fuel go,” he says.

“With all the equipment we operate, every gallon of fuel we save is important.”

In evaluating the wheel loaders, Crittenden says the Doosan units are durable and have great power for their size.

“I work with many different equipment vendors throughout North Carolina,” he notes, “and of course they all claim their products are the best. However, based on our experience the past two years, I can say to

them that’s not the case because when I compare what their machine can do and what my Doosan machine can accomplish, mine is much better. Plus, the economics of ownership and operating costs clearly favor the Doosan brand.”

Starting from its humble beginnings with just one machine, Yvon Talbot, owner of Talbot Excavation, has become a well-known success story in Saint Jerome, Quebec, where in 2012 his company celebrated 25 years in business.

Settled in the mid-1800s, Saint Jerome is located approximately 25 miles northwest of Montreal, in the La Riviere-du-Nord region. The population of the town has increased considerably in the past 10 years, due to the urban sprawl of Montreal and its northern suburbs. As the city has expanded, so too has its need for new and larger infrastructure, schools, commercial shopping centers and residential developments. Talbot Excavation is kept busy by the considerable construction activity in the area. According to Operations Manager Denis Belanger, the company does the engineering and construction for projects in a 20-mile radius of Saint Jerome.

“There’s a lot of construction around here,” he says, “and we don’t need to work

much further than our region.

"We’re involved in a lot of infrastructure projects, civil and government work.”

As evidence of the growth, Bombardier, a Canadian aerospace and transportation company, recently announced plans to build a new plant not far from Saint Jerome, and it will employ an estimated 3,000 people.

“That requires additional residential, institutional and infrastructure work to support the growing population,” Belanger says. “We are working on a new school, doing all of the excavation for the building … basically everything right up to when they start the building structure. We’ve done the engineering, infrastructure, mechanical, plumbing and electrical (underground) on the site.”

Right-sized Doosan excavatorsTo do all of this excavating, the company has invested in a fleet of Doosan crawler excavators, dating to 1999 when it purchased its first 30-metric-ton model. That number has grown ten-fold in the past 14 years, and now includes multiple 30- and 35-metric-ton Doosan excavators, including the 213-horsepower DX300LC and 281-horsepower DX350LC.

“The DX350LC is a very versatile size,” Belanger says. “It’s a good digging machine, but it has good lifting capacity, too. We do a lot of pipe placement and we need it to lift and place the pipe, and the DX350LC does it very well. It’s still small enough to get into some of the residential areas where we work, but it’s tough enough that it can deal with the rocks and the blasted material.”

STARTING FROM SCRATCH

A Quebec excavation company shares many similarities with its Doosan heavy equipment dealer: both started small and have grown successful, thanks to quality work and good customer service




Transporting heavy equipment is routine for employees of Talbot Excavation, and Belanger says the weight of the DX300LC and DX350LC makes them a popular size for their operation.

“The DX300LC and DX350LC are the most productive machines for their weight, and are easy to transport,” he says. “It’s not over the load where they need additional work, nor does it increase the cost to move them from site to site. In Quebec and a lot of northern areas, we have what we call the spring-time thaw period where the load restrictions are very severe. This size of Doosan machinery is not as restricted during that time. The restrictions are so severe that they can double the cost of moving machines from site to site.”

Among the features of the Doosan crawler excavators — in addition to their size and lifting ability — that Belanger and his crews like are operator comfort, good all-around visibility and ease of maintenance.

Belanger says one of the things that stands out with the newer Doosan excavators is improvements to the operating station.

“Doosan excavators have always been comfortable, but we’ve noticed that with the newer models, the comfort has improved, as well as the visibility, specifically the sight lines from the operator’s point of view,” Belanger explains. “The operators appreciate the air-conditioned cab and the nice joystick controls for more comfortable operation, especially when they’re in the machine all day.

“Doosan excavators are easy to work on, and they’re not complicated. The machines are well engineered. When our mechanics open the panels to access the service items, it makes sense to them. Also, in some cases, our mechanics will call the mechanic at Gauvin Equipment and they can resolve a problem on the phone. The responsiveness is very good; we never have to wait long.”

Exceptional dealer supportThe excavators were purchased from the local Doosan heavy equipment dealer, Gauvin Equipment, which shares some similarities to Talbot Excavation’s small business culture, according to Belanger.


Yvon Talbot and Denis Gauvin, the local Doosan dealer, have a good business relationship, but one instance in particular sticks out as an example of exceptional customer service. Operations Manager Denis Belanger explains.

“There was a time when we needed a part right away,” he says. “Gauvin is a pilot and personally flew from Montreal to Quebec City to pick up the part at one of his other dealerships, and then he flew his plane back to Montreal to deliver the part to us. That’s the kind of service that we’ve received from our Doosan dealer and we haven’t forgotten.”

GOING THE EXTRA MILE

A Doosan DL400 wheel loader is operated daily at the Talbot Excavation rock crushing center. Paired with a bucket, the wheel loader fills trucks with material to be used at Talbot Excavation jobsites.


“We like doing business with Gauvin Equipment because it’s a family company,” he says. “With other local dealers that we work with, we are treated more like a number. With Gauvin, they recognize us by our first names. It’s much more of a personalized relationship, and the level of service that we receive from the dealership is better than the service we receive from another local dealer.

“Gauvin Equipment is more responsive to our needs than other dealers. Denis Gauvin has worked very hard to build his business, and a lot of his customers, like us, have had the same experience. It’s a very personal and emotional thing to us, and Gauvin understands that. When we celebrated the company’s 25th anniversary last year, Gauvin was invited and he came here to congratulate us.”

Belanger explains that working with the same sales specialist is important to the business dealings with Gauvin. “There’s a personal aspect to our relationship, as well,” he says. “We’re like buddies, asking ‘how was your vacation,’ and it’s not just business.”

Rock crushing and reusing materialsIn addition to his excavating business, Talbot has a 12-acre portion at his headquarters that is set aside for processing aggregate for infrastructure projects. He says they produce about 100,000 metric tons of material per year, and it is native material that is extracted and processed. Roughly 80 percent of the material is handled for their projects, and the remaining is sold to customers. Most of the material processed at the facility is granite, which is processed in three-quarter-inch or less pieces for a top layer before compaction.

“We produce material between zero and six inches, which is used as the sub-base for road construction, and gives a strong base,” Talbot says. “The material gets smaller as the layers are added. We have zero to

two-and-a-half-inch that goes next, and between zero and three-quarter-inch material, which is the top, just

before the asphalt goes on.”

A Doosan excavator with a bucket loads the rocks, up to two feet in diameter, into the

crusher. Talbot says the first machine takes the bigger boulders and

crushes them down

to about six inches, and then it goes into a sorter where it may need to be crushed again to create the end product. When it gets to the end product, a Doosan DL400 wheel loader places the material in trucks headed for one of Talbot’s jobsites.

“A lot of the material that we process doesn’t come from a quarry, it comes from projects where we’ve blasted,” he says. “We create a lot of our own material and reprocess it from our jobsites where we’re excavating. Other contractors bring their material to us, too.

“It eliminates a lot of travel time because we’re taking the material, extracting it from the excavation site, rather than dumping it somewhere and having to get it, and we’re bringing it here where it is processed. Then, it can be sent from here to a jobsite where it is used as a base. It saves our company a lot of fuel from less transportation costs.”

Having a diversified excavating business that stretches from residential to infrastructure projects, and being able to process most of his own aggregate at his facility, are reasons why Talbot and his company continue to do well.

zone to an up-and-coming brand in southern Ontario — Doosan — when it purchased its latest model.

At Vicdom Sand and Gravel’s operation in Uxbridge, Ontario, a new color of wheel loader stands out from other brands of heavy equipment. A heavy-duty, orange and black Doosan DL550-3 wheel loader — purchased from the local Doosan dealer, Top Lift Enterprises — is making inroads with the owners and its daily operator, as it is utilized six days a week to keep up with demand for the company’s aggregate products.

Vicdom Sand and Gravel was started in 1976, but the company’s roots date back to 1956 when brothers Domenic and Victor Giordano started Giordano Sand and Gravel. Today, the company is known as Vicdom Sand and Gravel, with several sand and gravel pits and a limestone quarry in southern Ontario. Victor Giordano, who is still a part of the operation, works with sons and nephews Jim, Bruno, Vince and Sam. They estimate that the company owns approximately 5,000 acres and as many as 20 wheel loaders across its multiple locations. The company offers varieties of sand and gravel products, washed materials and limestone products, serving area concrete plants, asphalt plants, road builders, townships and regions.

Much of the material processed at Vicdom Sand and Gravel goes toward infrastructure

projects in the Greater Toronto Area (GTA). The GTA is estimated to have more than six million people living in approximately 2,750 square miles, and the city itself surpassed Chicago earlier this year to become the fourth-largest city in North America, trailing only Mexico City, New York and Los Angeles. Toronto, like many other major metropolitan areas in North America, is updating its aging infrastructure by repairing or replacing asphalt and concrete roads and bridges, which require aggregate material processed by companies like Vicdom Sand and Gravel in Ontario. According to the Ontario Stone, Sand and Gravel Association, its members supply the majority of the approximately 172 million metric tons of aggregate consumed annually to build and maintain Ontario’s infrastructure.

One loader + 10 hours = about 4,000 metric tons of materialDominic Cina has worked at Vicdom Sand and Gravel for 25 years. He’s seen a lot of changes in equipment during his tenure as a heavy equipment operator. Today, Cina’s sole machine is the company’s DL550-3 wheel loader, which he operates up to 10 hours a day, six days a week. This is his first time operating a Doosan wheel loader and he says the machine is comfortable to drive, provides good production and consumes less fuel than previous wheel loaders that he’s operated.

Regarding operator comfort, Cina points to several key features that make his long

days less tiresome and improve his overall operator experience.

“It starts with the seat,” he says, “which is comfortable with its arm rests. The climate control system is really nice, too. I can set it at whatever temperature I want and it maintains that temperature. I found some other loaders never seem to maintain the temperature.”

Operating for an extended time, Cina cites the joystick control as a particularly helpful loader feature.

“The single joystick makes it simple to control the wheel loader’s directional movements without using the steering wheel. The machine also has an automatic transmission to shift automatically from lower to higher and higher to lower gears for easy operation. Also, the ride control is nice when I’m traveling at speeds and hit a bump.”

Keeping up with production is priority No. 1 for Cina and he says the DL550-3 does everything he needs it to and more. The machine is paired with a 7.5-cubic-yard bucket to load a mixture of sand and crushed stone into trucks, and then the material is transported to a washing plant for further processing.

“What I really like about the DL550 is the torque converter lockup,” he says. “When I’m climbing hills, I lock the torque converter and the machine doesn’t slow down, it just keeps


LOADER FUEL CONSUMPTION COMPARISON

going up the hill; it doesn’t slow down at all on the hills.”

Available as an option on the DL300-3 through the DL550-3, the torque converter lockup clutch with five-speed transmission helps Doosan wheel loader operators climb grades easier and faster, increasing productivity as much as 20 percent in stockpiling applications. The option improves gear shifting for faster cycle times during truck loading and boasts high-gear performance during load-and-carry operations. Also contributing to the wheel loader’s productivity is the locking front differential, which is standard equipment on the DL550-3, and available as an option for interim Tier 4 Doosan wheel loaders, for improved traction in loose soil.

Cina says the all-around visibility from the DL550-3 is good, which is important for his truck-loading application, where the machine scoops, carries and loads granular materials for its entire workday.

“I’m using the Doosan wheel loader with a bucket to load material into trucks to haul it to our washing plant. These trucks are making about eight loads an hour, and we have two trucks running, so that’s 16 loads an hour. They’re carrying about 38 metric tons of material, and so that’s about 3,500 to 4,000 metric tons a day.”

It’s understandable why there is little room for downtime.

“We can easily put 30,000 to 40,000 hours on our wheel loaders before we retire them,” Giordano says. “We keep our equipment for quite a while, and when we’re done with them, there’s not much left. Machine longevity and durability are two key factors when we are evaluating equipment.”

Significant fuel savingsPaying particular attention to fuel consumption, Cina says the Doosan wheel loader consumes considerably less fuel than the wheel loader he previously operated. He closely monitors the machine’s fuel consumption and saves it in a spreadsheet.

“The DL550 is fuel-efficient, too,” he says. “I’m only using about 130 to 135 liters a day (there are 4.05 liters per gallon), compared to my old loader, which was using about 160 to 170 liters a day. So it saves about 30 liters a day, and it’s running more horsepower than my old loader. The DL550 is a bigger loader, with more horsepower, using less fuel.”

When you do the math, the company is saving approximately $36 a day in fuel (cost per liter of $1.21 U.S. dollars). That adds up to a possible $11,232 in annual fuel savings, assuming the wheel loader is operated six days a week or 312 days a year.

First in the areaGiordano says the company’s DL550-3 wheel loader was the first Doosan model of this size purchased in the area, and that he has been impressed with its performance and the comments from the operator. Giordano says his company’s previous working relationship with Top Lift Enterprises was important when it was time to purchase a new wheel

loader, and when Giordano coordinated equipment demonstrations to decide which brand to buy. Several local heavy equipment dealers brought wheel loaders to the sand and gravel operation for an evaluation.

“We asked the local dealers to bring us a machine, and we compared the Doosan DL550 wheel loader to some other brands,” he says. “We put them in the

application that we wanted the machine in, we ran them with the same operator, and then we got his feedback on them. We sat down after we evaluated all of the brands and made a decision.

“Bucket size was one of the key characteristics that we looked at, and obviously the comfort of the wheel loader and the engine performance, specifically how much horsepower it had, and breaking power (breakout force), such as breaking into bank (gravel). When it came down to it, for what we were getting with the Doosan wheel loader, we could not justify buying any other machine.

“We were privileged to have the first DL550 in this area. It’s worked out very well. I think the application suits it well, and the operator, of course,” Giordano concludes.
