Gottwald Generation 5 Harbour CranesFor All Ship Sizes, Terminals and Applications

A Dialogue on Generation 5Customers Ask, Gottwald Answers

Generation 5 includes all GottwaldHarbour Crane types, i.e. MobileHarbour Cranes, Portal HarbourCranes and Harbour Pontoon Cranes.

Generation 5 combines uniformitywith variety. All three types ofGottwald Harbour Cranes use abuilding block principle with manyidentical parts, which explains theshort delivery lead-times. At the same time, Generation 5 offers many crane variants as the com-ponents are selected to suit the crane’s respective use.

Customer: Can you specify?

Gottwald: A uniform design principle has been applied to theentire range of Generation 5 Harbour Crane models. They havethe same geometries for the chassis,superstructure, tower and boom. The cranes are designed for all common vessel sizes, and specific terminal and application types.

Depending on the model, they havelifting capacities of up to 200 t andradii of up to 56 m, hoisting speedsof between 75 and 140 m/min anda drive power of between 750 and1,645 kW. Moreover, eachmodel has its own 4-ropegrab variant, to cater forthe special conditions ofprofessional bulk handling.

Depending onthe intendeduse, the cranes canbe fitted with differenttypes of hoists with varying configurations and hoist speeds, and with the appropriate number ofslewing gear drive units and havingthe drive power required in eachcase. This is similar to principle in

Customer: “You Name it, We Craneit” – does this statement live upto all it promises? Customersspecify and Gottwald configuresthe crane to meet requirements?

Gottwald: That is exactly what it means. Every customer places different, individual demands on hisharbour cranes. As an equipmentmanufacturer, we must be able torespond flexibly. This is why we havedeveloped the Harbour Crane models6, 7 and 8 that are available in manyvariants with different configurations.

automotive engineering whereengine power and other equipmentfeatures are configured based on uniform platforms.

At the same time, factors such as the application and the annual operating hours have been taken into account so that all GottwaldHarbour Cranes are designed for along service life. This is a question of crane classification, a subject towhich Gottwald has paid particularattention during the development of Generation 5.

Customer: Crane classification?Could you explain this in a

little more detail?

Gottwald: It is not only aquestion of investing

in a crane with a high lifting

capacity. What useis having a powerful

crane if the crane landson the scrap heap after

just a few years? It is preciselywhen a crane is in constant use, e.g.performing intensive container orprofessional continuous-duty bulkhandling up to 6,000 operating hoursa year, that service life becomes acentral consideration. And this factoris linked with crane classification,

i.e. theanalysis ofdesign andbuild of themechanicalcomponents andsteel construction,and of the overallcrane structure. This is an importantlink that Gottwalddemonstrates in a particularly transparentmanner when determining a suitable crane classification(up to A8) to meet the customer’s requirements.

Customer: How canGottwald find the right solution from among themany variants?

Gottwald: This is where our experience of 50 years of HarbourCrane manufacture stands us ingood stead. On this basis, we havedeveloped a crane configurator that, using all parameters (vessel size, cargo type, annual operatinghours, etc.) helps us, in dialogue with the customer, to configure the appropriate model with theappropriate variant. All this information is presented clearly and concisely with all the necessarydetails.

The Dialogue ContinuedAll About Changes and Improvements

Furthermore, the number of axles onthe chassis ensures that Generation 5Harbour Cranes can be used, without problem, on quays with little reinforcement. To serve shipsthat are now stacked 2 containershigher, the Generation 5 Cranes have higher towers and higher-mounted tower cabs.

We also analysed the sub-suppliermarket and have ensured that onlystate-of-the-art technology fromleading manufacturers is used for our Harbour Cranes. These partnerscontinue to develop their productsalongside Gottwald.

Customer: Have you given anythought to service?

Gottwald: This is a very importantpoint. Harbour cranes are, after all,part of a complex transport chainand, in many cases, are operated for as many as 6,000 hours a year.We have attached great importanceto enhanced diagnostic possibilities.And, of course, to the optimal acces-sibility of all components. All themachines can be quickly dismantled,e.g. via removable side walls on thesuperstructure. For example, theentire diesel-generator set, which ismounted on a slide, can simply beremoved from the side. It has beenensured that service personnel canperform all work in a standing

Customer: Are there any new features and improvements?

Gottwald: Yes, many. Take, forexample, the individually steeredaxles that facilitate the exact positioning of the Mobile HarbourCrane by means of the crab steering function. Or the automaticpropping system that reduces thetime required for crane travel andpropping alongside a ship.

Other impressive features includeradio remote control to facilitate lifting gear change, or options such asthe innovative load guidance systemor antisway system to increasehandling performance. Depending on the application and ambient conditions, handling performancecan be increased by up to 20% with Generation 5 Harbour Craneequipment.

position. The superstructure that now has two floors boasts greaterspace for machines and components.Thanks to the high quantity of common parts in all crane models,i.e. standardised spare parts, customers benefit from simplifiedspare parts management.

Customer: Do environment andsafety also play a role?

Gottwald: With the Generation 5Harbour Cranes, not only have weextended the range of application,but also enhanced the portfolio, andfurther developed the technology.Customers today have specific require-ments regarding environmentally-friendly and safe harbour crane operation. Ultimately, it is also aquestion of keeping pace with

“green port” developments, protecting man and machine, andsignificantly increasing handling performance in face of keen competition by introducing semi-automation.

The Gottwald diesel-electric driveconcept, also used in Generation 5,contributes greatly to this environ-mentally-friendly way of thinking. It ensures low sound emissions andoutstanding efficiency, resulting inlow fuel consumption and minimumpollutant emission.

Customer: What makes you sosure that the new Generation 5will be successful?

Gottwald: Naturally, we have soughtintensive dialogue with many differentcustomers; some of whom havecranes in continuous operationthroughout the year, and yet otherswhose annual crane usage times do not exceed 2,000 hours.

As a result, we have experienced the entire range of customer requirements. And it is from thisprocess that the Generation 5 modular concept was developed,making it possible today for eachcustomer to have the Harbour Crane best suited to his individualrequirements. The Generation 5 principle sums it up: You Name it, We Crane it.

The tyre-mounted and manoeuvrablechassis on models 6, 7 and 8 is based on a uniform design principle.As this principle is applied to theentire range of crane models, chassisvariants with varying numbers ofaxles have been developed. Two of the chassis axles are driven by high-performance hydraulic motors. Model 8 has a third drive as anoption.

Large wheels with 1,500 mm diameter make it possible to travelover obstacles, rails, and quays withuneven terrain, while maintenance-free equaliser beams with vertical

compensation of up to 500 mm (+/- 250 mm) ensure that the axleload is always evenly distributed.

Innovative Axle ConceptAn innovative axle concept, enabling each of the axles to besteered individually, permits the craneduring travel not only to achieve thesmallest possible turning radii, butalso to perform crab steering at a 25°angle to the longitudinal axle of thecrane. For this reason, GottwaldCranes are easy to manoeuvre andposition alongside the ship, even inthe tightest spaces. The individuallysteerable axles also reduce tyre wear.

20

Refuelling During CraneOperationThe main fuel tank, which has a filling capacity of up to 10,000 l for intensive crane operation, is located in the chassis. The benefit:the centre of gravity is lower in thecrane, thus minimising vibrationscaused by flowing fuel. Fuelling during crane operation is also possible in compliance with localguidelines.

The superstructure of models 6, 7 and 8 is built on a uniform designprinciple based on the same geometry.It is only the central part on the steelconstruction that varies. The super-structure has an active dust protectionsystem and two floors connected toeach other by a spacious stairway.Thanks to the generous headroom of 2.5 m on each floor, maintenancework can be performed standingupright.

All the machines, drives and electricalequipment are arranged in separaterooms in the superstructure. A fancreates a positive pressure in thesuperstructure, thus preventingingress of dust. The diesel-generatorset and hoists are located in thesuperstructure rear section, thusreducing the overall weight of thecrane; the counterweight forms apositive-locking link with the super-structure.

The rooms not only provide plenty of space and excellent access to all the equipment, but are alsodimensioned so that machines anddrives in various numbers, sizes and ratings can be fitted, providingroom for the diesel-generator set,hoist and slewing gear variants.

Diesel-Electric Drive ConceptGottwald Harbour Cranes are eitherpowered by a diesel-electric drive or the shore power supply. All models can also, as an option, beprepared for external power supply.All diesel-generator variants have sufficient power to perform all crane functions simultaneously and independently of each other.

The drive power required depends on crane use. This is why the engineroom and the connection geometry

Generously-dimensioned platforms on a two-floor superstructure provide easy access for service and maintenance work

for the diesel-generator set and auxiliaries are arranged in such a way that there is sufficient space for machines with various ratings.

The entire diesel-generator set ismounted on a slide in the sound-proof room. For overhaul work, the slide can be removed sidewaysfrom the superstructure using standard port equipment.

Hydraulic UnitThe hydraulic unit provides thepower for the luffing gear and forthe propping, travelling and brakingsystems. Mounted high on the superstructure, the luffing gear andits valve block can be easily accessedvia a platform.

Electrics RoomThe electrical equipment and control system are located in aclosed, air-conditioned room. Thecomponents are clearly arranged in functional groups and are easilyaccessible. A diagnostics standenables easy troubleshooting.

Easy access to hoist The slewing gear pinion transfers forcesto inner-geared roller bearing slew ring

Slewing Gear Drive UnitsThe slewing gear drive units, whosenumber, depending on the cranevariant, ranges from 1 to 4, arearranged in a modular design. Theyconsist of a DC motor for smoothacceleration and deceleration of theslewing motion, flexible coupling,disc brake and reduction gear unit.The slewing gear drive units transferforces to the inner-geared, three-rowroller bearing slew ring.

HoistsThe hoists, fitted with a limit switchsystem, consist of a DC motor, spring-loaded disc brake, reduction gear unitand rope drum. These componentsare grouped in a U-arrangement for excellent accessibility and heatremoval. The DC motor ensuressmooth acceleration and decelerationof the hoisting motion.

The hoist configuration, i.e. the number and arrangement of thehoists in 1 x 2, 1 x 4 or 2 x 2 groups, is determined by the crane type,crane variant and application. Thecorresponding machinery room isdesigned in such a way that there issufficient space for easy maintenanceand service.

Hoist Variants:

■ 1 x 2 = one 2-rope hoist

■ 1 x 4 = one 4-rope hoist

■ 2 x 2 = two 2-rope hoists

A speciallydesigned ropearrangementbetween the towerand the boomallows for a horizontalload path. The torque-controlled cable reelensures excellent powercable guidance and longcable service life.

Ease of MaintenanceAll crane models have generously dimensioned platforms at the tower/boomand tower/rope pulley connec-tion points, making the use ofadditional cranes for maintenancework unnecessary.

With the New Design, the Sky is the Limit The Tower and the Boom

26

The TowerThe tower on models 6, 7 and 8 is atorsionally stiff plate girder structure.The safe and weather-proof stairwayto the tower cab is quickly ascended.It has comfortable steps with an inclination of 50° and platformsinside the tower. An ample numberof ultra intensive lamps on the towerand boom guarantee a good view ofthe entire work area at night.

The high tower with its high-mounted tower cab particularlyaffords an excellent view of the shipfreight bays. In order to improve theview, especially during bulk handling,the cab can be forward-mounted by2.5 m, if requested.

The BoomThe rigid, torsion-free boom is aproven tubular-lattice constructionand is mounted high up on thetower to provide ample room foraccess when working with high container stacks.

The boom head and root are now no longer attached with pins butwith flanges. This new constructionremains immoveable throughout thelifetime of the crane and makes theboom more rigid, which simplifiesthe task of operating the crane.

Crane Classification and Service Life Based on Gottwald Reliability and Transparency

Factors such as the application and the annualoperating hours have been taken into accountso that all Gottwald Harbour Cranes aredesigned for a long service life

Many factors must be taken intoconsideration when investing in a crane. These factors include the lifting capacity, crane use and application and the number of annual crane operating hours, inother words, the number of workcycles that a crane undergoes.

Often great value is placed on a“powerful” crane, i.e. a crane with a high lifting capacity. If too muchsignificance is accorded to thisrequirement, however, a secondaspect – namely the question ofcrane service life – is in many casesneglected.

The task of the handling equipmentmanufacturer is to evaluate the significance of service life and maketransparent the determining factors.For what is the use of a powerfulcrane if it lands on the scrap heapafter just a few years?

Loading of CranesOwing to the various operatingmodes (heavy load, container or grab operation), the loading ofcranes is not uniform. The loads also vary greatly; sometimes containers or grabs are filled withmaterial, and sometimes they areempty. And in heavy-load liftingoperation, the cranes are workingnear the limit of their lifting capacity.

The load spectrums include these different parameters as demonstratedin the F.E.M. 1.001 Design Rules, and thus attempt to describe theactual loading of a crane.

The total of 4 loading spectrums(designated by Q1 to Q4) refer to the intensity of crane operation and take into account, for example,whether the crane must move onlysmall loads and seldom maximumpermissible loads, or must frequentlymove maximum loads.

Loading CapacityWhile loading is a question of theintensity of crane operation, loadingcapacity is concerned with the craneitself. For the manufacturer can produce the crane in eight appliancegroups as per F.E.M. (with the designations A1 to A8). The higherthe appliance group (max. A8), the greater the wall thicknessesselected by the manufacturer forsteel sheets and tubes, and the more robust the crane as a result.

Service LifeThe estimated number of work cycles and the service life of a cranecan be derived from the type of loading and the loading spectrum on the one hand, and the loadcapacity (steel construction andmechanical design and condition of the crane) on the other.

The Higher the Appliance Group,the Longer the Service LifeThe higher the appliance group, alsoknown as “classification”, the longerthe service life when subjected to thesame loading spectrum. This explainsthe fact that a crane classified inappliance group A8 is designed formore than 4 million work cycles,whereas a crane in appliance groupA6 with the same loading has

already reached the end of its servicelife after 500,000 work cycles.

F.E.M. Classification According to Customer RequirementsGottwald takes all these different factors into account when designingthe Generation 5 Harbour Cranes so as to select the most suitable classification to meet customerrequirements.

Given the same loading, anincrease in the appliancegroup by one level (e.g.from A6 to A7) correspondsto a doubling of theexpected service life. Forthe step from A7 to A8,equivalent values apply.

Radio Remote ControlThe standard scope of supply includes a radio remotecontrol that is used to perform all crane functions. It is particularly useful to control crane travel from theground or to replace lifting gear. It is also invaluable for heavy-load lifting.

The control unit, which takes the place of the control stand in the driver cab, is simply placed in a holder providedfor this purpose. It is compact,light-weight, robust andweatherproof. Its LCD displayshows the same symbols as the screen onthe tower cab,making handlingparticularly simple.

Handling Made EasyEquipment Features for Harbour Crane Operation

Cab mounted high on the tower.As an optional feature, it can beforward-mounted by 2.5 metres.

Generation 5 Harbour Cranes boast many technical enhancementsin addition to a range of featuresspecially requested by crane operat-ing companies, crane operators andservice personnel. These features alsoinclude a high degree of operatingcomfort, automation of frequentlyrepeated motions, safer crane operation with high availability andextended diagnostic possibilities.

CabsThe equipment includes a tower cab and a driver cab. The tower cab,from where all the crane functionsare effected, affords the crane operator an excellent view of theentire work area. With an especiallyergonomic and comfortable design, it provides him with the ideal environment for achieving high handling rates. The crane operator is also supported by the video systemthat supplies images via the cameramounted on the boom head to thetower cab monitor.

Visumatic® – Control andVisualisation All in OneGottwald has designed and developed its Visumatic® CraneManagement System based on itsextensive experience in manufacturingHarbour Cranes. The system is basedon state-of-the-art bus technologythat permits a multitude of data to be transmitted simultaneously,securely and quickly.

Visumatic® also shows all the cranefunctions on the monitor. Differentoperating modes are selected from a menu and there is a statistical evaluation of handling performance,operating hours or current mainte-nance statuses.

The Range of PossiblitiesMoreover, the Visumatic® providesmany further control features thatfurther increase operating safety andcrane availability – and the operatorswill either find these features availableas standard on the crane, or asoptional pieces of equipment thatcan be installed independently.

Standard equipment includes, forexample, an automatic proppingfunction with propping pressuremonitoring and a series of diagnosticfunctions.

The load guidance system, availableas an option, ensures even safer andmore comfortable operation withsuch features as:■ load linear motion■ antisway,■ point-to-point handling mode and■ hoisting height limiting system.

The semi-automatic point-to-pointhandling mode facilitates high-speed load movement or ensures the simplest route to a destination,such as to a hopper. The hoistingheight limiting system ensures thatcontainers are deposited gently andsafely on the quay. The antisway system, on the other hand, primarilyhelps inexperienced crane operatorsto achieve higher handling rates.
