Translation of page 3

Passion and Enjoyment

Are you comfortable? Maybe you are seated in your favourite easy chair beside the fireplace.

You are holding the first issue of BAGGERMODELLE and looking forward to spending some quality hobby time reading the many fea-tures.

During the last year I often ima-gined a setting just like that. I sin-cerely hope, that you, the readers and collectors, exist out there as an audience. I also hope that you do not belong to the fast crowd, sur-fing for bits of information on the net, but prefer to read and re-read the same book or magazine a coup-le of times and to study it in depth.

I am not advocating in any way against computers and the Internet; without them the BAGGERMO-DELLE magazine would not have been possible. I just think that they do not give the same recreational value as being more intimately in-volved in the hobby.

Collecting models has much to do with being passionate. It is the same with magazines!

I spent the past year in the pro-ject phase of the magazine, and yes, it took that long, and it was a very exciting process.

I was looking forward very much to being able to hold the first issue in my hands. I tried to find a good mix of interesting articles both in prototype and models. Of course, this would not be possible without the support of all the contributors who have provided text and pho-tographic submissions. Thank you to all.

In the first issue are reports about the world’s biggest mobile crane and the model version of the same. An impressive collection of a fleet of models is featured. We discuss the newest Bulldozer model and visit the world’s most modern mi-ning excavator.

I sincerely hope that you like BAGGERMODELLE magazine and I invite you to send me your comments about the magazine. Please tell your friends about BAGGERMODELLE magazine and invite them to the growing cir-cle of subscribers.

Enjoy reading BAGGERMO-DELLE!

Yours Sincerely,

Daniel Wietlisbach

Caterpillar D7E (Norscot)

The engineers who conceived the model can be justly proud of their achievements as the model is cor-rect in all proportions and details. The track suspensions are very fine and smooth, so that the tracks still move easily. Also, the scale thick-ness of the hand rails, the wind-screen wipers and headlights have not been neglected whilst the cabin has a complete interior.

Northwest 25D (SpecCast)

Afer producing a dragline set exclusively for Toyfarmer, the beautiful digger is now available with a high arm scoop. Especially appealing is the driving unit with metal tracks made from individual links. The upper part is also very

nicely done, Esporting free stan-ding hand rails and an opening door whilst the paint job and let-tering are well executed. An inclu-ded key is used to move the stick and excavator arm up and down, other functions are not featured. Unfortunately, both sets of ropes have been mounted the wrong way around but with a minimum of work, this small flaw can be easily corrected.

Weimar T174 (Busch)

The well-known Weimar digger in 1: 87th scale has been newly is-sued as it was used by the German Volksarmee in the correct color scheme for that period. The paint work and lettering are superb and the model comes with a grabber hook.

Excavator bucketsets (BSB Models)

Brian Blackman produces diffe-rent sets of buckets in 1: 50 scale. The excavator buckets are made from white metal and free of flas-hing. The most unusual bucket is the digging scoop in a V shape from the set for the Liebherr R916 by NZG. There are two other sets available, one for the Liebherr R313 by NZB(back left) and one for the JCB 3CX by Motorart (back right).

Liebherr R994 (NZG)

The superb model of this giant digger looks even better in the Mt Arthur Coal Mine color scheme. The prototype for this model can be found working in a coal mine located in the eastern part of Aust-ralia in the Hunter Valley.

The weighty model is highly detailed, featuring freely movab-le tracks, fine hand rails, window wipers, hydraulic lines to so much more.

Caterpillar 140M (Norscot)

the newest Grader model from the American supplier again shows first class workmanship. The model mimics all movements of the pro-totype. It does not stint on details;


for example the hand rails and win-dow wipers are extreme fine. The roomy cabin models a full interior including the joystick steering and shows off its big window surfaces very well.

Sennebogen 835M (NZG)

How huge excavator/loaders really can be is shown by the im-pressive and highly detailed model that NZG produced exclusively for Sennebogen. The model is equip-ped with a scrap grabber and is ful-ly functional. Available only direct at the Sennebogen-Shop: www.sennebogen.de

Grove GMK 5095 (TWH)

This five axle crane has a tele-scoping arm that extends up to sixty meters and has a lift capacity

of 100 tons. The model is highly detailed and mirrors the prototype. Just like the original, it can be built up and equipped with additional winches and heads. The futuristic looking cabin of the Grove series could not have been easy to dupli-cate and has been copied extreme-ly well.

Along with the set comes a ori-ginal prospectus, slightly reduced in size.

Dozer-Set und Bagger (Siku)

A lot of machinery for little con-struction managers. Siku is relea-sing the Volvo EC290C in 1:50 and low boy tractor/trailer set with the Liebherr PR 764 in !:87 scale. All models are of a robust construc-tion, necessary for the hard work out on the playroom floor. Siku clearly positions itself as a toy mo-del producer.



The 1:1 scale Poclain

EC 1000 was introdu-

ced to the astonished

public for the first

time during the 1970

construction machine

exposition Expomat

in Paris as the world’s

largest hydraulic ex-

cavator.

By Albert Schmid

With it’s huge dimensons and power output, the EC 1000

towered over all previously concei-ved machines. It weighed in at 140 tonnes and produced 780 Horse power. The power plant contained

3 GM or, as an option, Deutz Die-sel Engines which were neccessary to deliver enough power to the six hydraulic pumps with a pressure of 320 bar. It was delivered factory equipped with a seven cubic meter dump shovel or deep bucket exava-ting scoop as standard, achieving a loading capacity that had never been seen before.

In 1990, a full twenty years after the first appearance at EXPOMAT, the Poclain EC 1000 was re-intro-duced, this time as a model in 1:50 scale produced by Virus CEF Mi-niatures, France. Only 1000 pieces where produced as a limited editi-on and for collectors, this seems to be a small number. To put it in to perspective, only seven of the real EX 1000 units had been produced up to 1975.

As a footnote, it is interesting that the seventh unit never left the factory and was used as a donor for spare parts for the units still in service.

The Giant from Gaul



Peter Klinger does not collect single pieces

of construction equipment and a picture of a

single dump truck does not interest him. How-

ever, a picture taken on a Sunday of a mega

construction site with 20 or more of the same

machine lined up as on a parade ground does

interest him very much. And this is exactly the

same way they are lined up in 1:50 scale in

Peter’s display case.

By Daniel Wietlisbach

As with many others, Peter’s passion for collecting scale

construction equipment started in his childhood. He grew up beside a highway construction site near Berne where his fascination with the big yellow machines began. He watched scrapers, bulldozers, excavators and numerous dump trucks in constant use on the im-mense construction site.

Peter received his first model, a Mengele HM 1035 Wheel Exca-vator (NZG 174), already detailed with hydraulic lines, from his Fa-ther and it is still a prized piece of his collection.

One day on his way to look at construction sites, Peter noted a man walking and searching in near-by fields. He was looking for Lake Dwellers Bronze Age artefacts and

fledgling hobby became available. The real foundation of today’s coll-ection started with the purchase of a complete collection from a fellow enthusiast. Through swapping and selling duplicates, more models where acquired and construction model fleets now became the main interest.

Other collectors are amazed when gazing in to his show cases.

Imagine one dozen Cat 621 Scra-per (NZG 122), also one dozen Cat 621 / Athey PR 621 rear dumper (NZG 132), just as many Cat D9 (Conrad 287) and Cat 594 pipe layer (Conrad 2872), in every paint scheme produced, all lined up and ready to go to work. The crowning glories of the collection are 28 mo-dels of the Volvo A25B.

The space available for the hobby mattered when considering the size of the collection. The huge dump trucks and giant mining excavators where sold off. Peter’s motto chan-ged to nothing over 100 tons and only items that he has seen in ac-tion and so could better relate to. In 2001, there where over 1700 mo-dels on his inventory list and today there are about 1400. Less is often more, and quality improves.

The collection now focuses on two main areas: earth movers and specialized foundation construc-tion equipment.

His answer to “What is the fas-cination with construction equip-ment?” comes fast: “It is the smell of the churned up earth mingled with diesel fumes, the power and the noise”.

For example, an enjoyable after-noon was spent recently observing one of his favourite machines, the Frutiger SR 2001 Scrape Dozer. It is one of the last examples of this

Fleet Collector

was grateful when the youngster of-fered his assistance. Peter received a couple of construction models as compensation for his efforts which he added to his growing collection. Among them was the then popu-lar JCB Excavator/loader made by Corgi Toys, scale unknown.

Word got out, that the greatest gift for Christmas or birthdays for the boy was a construction model. His older siblings knew about this fascination and added to his coll-ection. As time went on, Peter worked at summer jobs to afford the expensive models and later on, girl friends took priority and pu-shed his collecting interest in to the background.

New beginning

After marriage, and beginning a family, time and space for the



machine, which is unfortunately threatened by extinction. Up under the roof in the hobby room there are five of these behemoths, pro-duced exclusively for Frutiger by NZG (Item 398).

The greatest rarity is a model of DJB 275 (NZG 166).Only one of these superbly conceived centre pi-vot dumpers graces his collection, an exemption to his general rule.

His passion for collecting is fi-nanced by consignment and re-sale of existing collections. This is also the reason Peter Klinger has his own table at the yearly show. “The model must be worthy of my asking price. I do not ask over in-flated, prices.” And because of that “I would never get in over my head financially when purchasing a mo-del”. My collection is important to me, says Peter, but it does not take first place in my life.

Unfilled wishesand improvements.

Missing and very much wanted by Peter and by many other coll-

ectors are models of excavators in the 30 ton class. At this time they are available only in either very small or large scale model form. If he could commission his own preferred model, it would be an Åkerman H14B with all the detail possible today and of course in an affordable price range. These Swe-dish excavators with their unique colouring can be found in common use on construction sites around the country and abroad.

Since Peter is also engaged in building dioramas, he is constantly on the lookout for detail parts. He scratch builds diesel tanks himself and has other modellers building parts such as casings, concrete pi-lings and sheet pile wall sections for him.

He is no longer searching to add new models to his collection and in order that his models are as realis-tic as possible, Peter does not shy away from upgrading a model so that it passes muster. He adds new hand rails made from brass, new search lights, rear view mirrors or even new tires. This often means

one new model is created from two old ones. Silent witnesses to this fact are the several boxes of parts in his modelling room.

Especially realistic are the mo-dels that show off open doors and complete interiors, including the operators. Even the house cat’s whiskers are used to make the very fine looking radio antennae!

Collectors portrait

Peter Klinger, 52. His dream as a boy was to become a heavy duty mechanic. His application for an apprenticeship was denied and came back with the note: only average grades in sport –means that the applicant is lazy!“ Soon after completing his training as a sheet metal worker, Peter was promoted to Shop Supervisor. Parallel to this he also made great advances in his army career in the Rescue Troops and ended up being able to drive a Hough Wheel Loader among other machines. Today he works as a Mailbox Installer.

He is married with two children, boys 16 and 18, who unfortuna-tely do not share their fathers’ passion for his hobby. Besides collec-ting and observing construction equipment, he is interested in dogs and teaches obedience classes at a dog school.

The world record breaking spe-cifications of the crane are re-

ally impressive with a maximum load bearing weight of 1200 tons; the telescoping boom can be exten-ded to the maximum length of 100 meters. Since its introduction at the BAUMA the new crane has proven it’s mettle in use and shown it’s ca-pabilities to the fullest.

The LTM incorporates many in-novations, especially concerning the assembly of the telescoping boom and the operating cabin. Be-fore we introduce the equally fas-cinating model of this giant, lets look at the prototype first.

Target market: Wind Power

Wind power, especially Wind Turbines, are the driving force behind the development of this crane and even in times of econo-mic downturn the investment in

wind power remains strong. For the erection of the up to 100 meter high turbines, producing between 2 to 3 Megawatts, it is usual for lattice type construction cranes to be used. However, transportation and erection are time consuming and complicated and this is where the LTM 11200 shines. With the telescoping boom measuring 100 m and the Y suspension system, it is capable of lifting power plants weighing 100 tons up to the top of a tower measuring 80 meters in height. Furthermore, it is possible to move the crane within the wind park, since it is very manoeuvrable and the arm can remain on the cra-ne. This contributes to a substantial reduction in preparation and down time.

A Liebherr 8 cylinder diesel en-gine powers the crane on its nine axles. The power plant for the ac-tual crane part comes from a 367 PS Liebherr engine. Despite a length of 20m, the chassis of the

crane is very manoeuvrable and all axles are steered individually whe-re axle six to nine are not speed dependent.

It has the longest boom

The telescoping boom of the cra-ne can be adjusted optimally to the task at hand. The telescoping boom contains the base and seven units, code # T7Y. For a lattice construc-tion crane, several low boy trailers are required for transporting the unit and yet for the LTM 11200, only one is needed. The telesco-ping action uses a system called TELEMATIK, which drives the different lengths of the boom and connects them with bolts.

If the maximum length is not required, then the inner most four sections of the telescoping boom can be removed. A heavy lift head connected to boom three then gives the unit a maximum length of 55m. A further option is the addition of

With the introduction of the new LTM 11200-

9.1 at the 2007 BAUMA Exposition, Liebherr

Pole Position it held in the greatest telesco-

ping boom cranes.



a choice of several lattice tips, in-cluding a balancing tip up to 126m or a fixed lattice tip of 60m. This option can also be adjusted with a hydraulic system.

The Y suspension can be used with all these options; greatly in-creasing the load capacity. For ex-ample, the 11200 can, with a 100m height and an extended arm length of 18m, lift only 22 tons without the Y suspension, increasing to 62 tons when the Y suspension system in deployed. The suspension also reduces the curvature of the arm which can be substantial without the suspension used!

For the transport of the crane on public roads, the telescoping boom is carried on a low boy trailer. The weight of the boom with the Y sus-pension weighs in at an impressive 104 tons! The chassis itself weighs 108 tons but can be reduced to 76 tons. For this the support legs and winches have to be removed. No crane helper is needed for the re-assembly as the LTM 11200 has a built-in self assembly system. How this works in detail is covered in the description of the model article.

Since the delivery of the first cra-ne in September 2008 for the Dutch firm of Mammoet, the LTM 11200 has successfully showed what it’s capable of achieving.

The first task of the new LTM 11200 crane was to extend the height of a communication tower in Amsterdam. For this task the crane was used in its 55m arm configura-tion with a 90m balance tip and at-tached Y suspension. For this mis-sion, 16 low boy trailers where in use besides the crane and it would have required 5 additional trailers if a regular lattice type construction crane would have been used.

The LTM has proven this kind of savings and economies several times since then. All big crane lea-sing firms like van Marwijk, Roxu, McNallys, Northern Crane Hire, KVN, Mediaco, Franz Bracht and Eisele now have the LTM 11200 in their inventories. More of the other firms will surely follow.



By Carsten Bengs

This was the first time that NZG had produced a Liebherr crane

prototype and fittingly, NZG deci-ded on the LTM 11200-9.1

The suspense was great among collectors to see the results be-cause for NZG, this was to be the largest model produced by them so far. For our report, we were given a pre-production model.

The model specialists from Nu-remberg scored the prototype high on fidelity to details and the LTM 11200-9.1 from NZG far exceeds my personal expectations of func-tionality.

Assembly of the model

The first step in assembling the model is to install the telescoping boom. The conception of the mo-del by NZG is such that it is true to the original. (The boom has to be transported separately to the cons-

truction site due to the 100t weight of the boom where it is then joined to the platform at the construction site).

The telescoping boom is sup-ported by a system of support legs which have some astonishing de-tails. All supports can be opened up and can be secured with small bolts. The feet of the

supports can be folded down and a special locking mechanism insu-res the stability of the model.

The support cylinders are then turned outwards and little and sup-port feet are then attached with small bolts. NZG has turned the th-reads inwards so that only one hyd-raulic cylinder is visible. Hopeful-ly this solution can be carried over to future models as well.

After the boom is secured, the crane chassis can be driven un-der the boom and be bolted to the lifting cylinders. The connecting bolts to the arm are a nice feature since they are in the original color

and correct model of bolts rather than being just pieces of wire. Now the arm can be lifted and secured at two angles with bolts. When the crane is taken out of the box, one can not help to notice the heavy weight of the telescoping boom – just like the full sized prototype.

Telescoping Boom Options

It would be hard to top the build-in flexibility in the outrigger sys-tem of the model.

Like the prototype, the crane can work with a shortened boom con-sisting of only 3 of the telescoping parts. In this configuration, the model achieves 1.25m length in-cluding the heavy load head piece. With all seven telescoping parts the length grows to a 2m. If the crane lattice top is added it measures in at a proud 2.25m!

With all boom variants the Y ten-sion straps can be attached with small screws provided. If the mo-

del is displayed without them, the upper deflection pulleys remain in the base of the arm and so cannot fall out. The rear Y frame tie down wires are also modeled and made from several plastic rods connec-ted with miniature clamps and not with scale rope, a nice and realistic touch.

There are a total of three heads packaged with the model which, in the real world, would be used for a maximum lift of 320, 112 and 16 tons respectively. The choice of head is dictated by the version of the model built. When using the heavy lift version, the heavy duty head with 11 pulleys for the maximum lift is indicated and for maximum telescoping extension the head with three pulleys for 112 tons should be used.

All heads have very smooth ope-rating pulleys and feature hooks that rotate. The production model from NZG will be equipped with a new type of scale rope that bani-shes the annoying twisted rope of past models for good.

The Chassis

The chassis weighing in at 108 t without the boom on the prototype has 9 axles, and the detailing in the model of this feature is really con-vincing. Finding that all axles in the model are moveable and have suspension is wonderful and qui-te unexpected. There is no rolling resistance so that the model moves very easy when placed on a smooth surface like a desk.

The stabiliser legs which can be folded down and telescope are abo-ve small hydraulic cylinders. The threads are hidden here as above, and well hidden inside. They are connected with small bolts and support the model well. Even foot protection mats for the crane feet are included and with small adjust-ments, the supports always stay le-vel which looks superb!

The detailing continues on the crane chassis. Exhaust stack, air filter and ladders are depicted very nicely and there is also a small tool box near the rear support feet. War-

ning lights, a plate with registrati-on numbers from Ulm, mirror and window wipers are all there and correct.

Both cabins have fully detailed interiors. The upper cabin has a pedestal with hand rails and is attached to a swivel arm. The operator’s cabin can also be tilted backwards, powered by a small hy-draulic cylinder.

With the Liebherr LTM 11200, NZG has not only produced a gi-gantic and fascinating model in greatest detail, but has also pushed the boundaries as far as functio-nality is concerned. No wishes of the concerned modeller are left un-addressed. I am looking forward to seeing the firm’s color scheme ap-plied as well as to the arrival of the Mammoet version. The LTM11200 is a true feast for the eyes of coll-ectors.

Telescoping boom low loader tractor trailer from WSI

The low loader tractor trailer model for the transportation of the telescoping boom is being produced by WSI in two exclusive ver-sions:

In the Mommoet color scheme with a MAN TGX 41.540 8x4 trac-tor in a set with LTM 11200 (www.mammoetstore.com) and in the Nooteboom Shop who are offering a version of the crane in neutral color scheme in a set complete with a Mercedes Titan Mp# 4165 tractor. (www.noteboomgroup.com/shop)

The model is the Nooteboom NLD70 with dolly, supplemented with two new crane adapters developed in co-operation with Lieb-herr, NZG and Mammoet. Because of the heavy weight of the four inner telescoping pieces of the arm, in the prototype they are trans-ported separately. This can also be modeled. (see the preceding main article)



The accessory spe-

cialist Viessmann has

made scale workers

come alive with their

new “eMotion, a world

that moves”.

By Daniel Wietlisback

Starting a few years ago, the Viessman factory located in

Hatzfeld began to produce moving figures for the model railroad en-thusiast. With this line, they hit the bulls-eye and after the successful issue of “Railway Maintenance Crew”, ” Construction site wor-kers” followed. The little people shovel, lay bricks and paint and it is a real pleasure to watch them. The sets are of course very well suited for the construction diorama and, when cleverly deployed, catch the eye for more then just a mo-ment and my favourite is the man at the concrete mixer. This set has, besides the man at the mixer, the mixer itself, a pallet with bags of concrete, a water barrel and bucket and a completed piece of wall.

It is straight forward to use

The worker is movable and turns. He is fixed to the display at the bottom of the gravel heap. To mount the display a hole of 12 mm needs to be drilled. The cylinder of the set, which contains the elect-ronic bits for the display is inser-ted in to the opening and a depth of 5 cm is required. The cylinder is then attached with the included metal ring and secured by giving it a 90 degree turn. If the gravel heap, made from the gravel in the kit, is used to blend it in to the surroun-ding terrain, the outmost care has to be used or the smallest particles will foul the delicate mechanism. The two power cables, yellow and brown, can be attached to any po-wer pack that has an AC outlet for accessories and lights. I tried it out with a forty year old, dusty Maer-klin power pack and this was quite sufficient to get the little brick lay-er working without any problems.

Lesson of the small kit building effort: small effort great effect. The little worker is quiet, charming and (eMotionaly) moving.

Here you can test

your knowledge. Re-

cognize the prototype

and win a model!

By Remo Stoll

I discovered this wonderful old grader during a Sunday walk

and for its age, it is in surprisingly good condition. Part of the reason for this is the dry storage place where it resides. I assume that it sees action once in a while, but probably rarely.

ContestDo you know what model it

is? If so – then send us the exact manufacturer’s name and the mo-del number on a post card by mail. We also accept email submissions (addresses can be found on page 42). The contest ends on Decem-ber 15, 2009. Should there be more then one correct answer, a draw will be held.

The winner will receive the Liebherr R994 painted in Mt Ar-thur paint scheme and the Terex TA6s mini dumper from NZG and, from BSB Models, a set of four ex-cavation buckets to fit the Liebherr R916 advanced.

Solution to the mystery prototype from sample issue

Maybe you knew the prototype shown in the O number, although there where no models offered as prizes. If you are still scratching your head, here is the solution:

It is a Caterpillar D8D painted in Swiss Army colors.



First Gear has finally

produced the HD-21

in 1:50 scale and it

has an ejector scraper

trailer in the set.


For a long time, First Gear has produced the HD-21 in the lar-

ge 1:25 scale and now, 1: 50 scale collectors can look forward to the newly released models which are available in two versions. There is a hydraulic operated dozer version in yellow and one in white with the ejector scraper trailer.

The dry type, two stage filter with the distinctive air intake over the engine hood clearly identifies it as model HD-21A which was pro-duced in 1967 with the upgraded engine producing 286 hp. The “football” logo was applied for the first time in 1960, and the mo-dern A-C triangle logo for the first time in 1965. Starting in 1960 all construction equipment was pain-ted in yellow whereas the same equipment for farming was painted orange.

Especially noteworthy are the fine control sticks and knobs in the cockpit in scale thickness that is a definite improvement over previ-ous offerings.

The six cylinder Allis-Chambers diesel engine is also finely detailed and the radiator grill cover is made from a finely etched white metal material.

The Hydraulic pump is hidden behind the covering in the lower part and, true to the prototype; the cylinders and lines for the hydrau-lic system are all there and look very realistic. There are two additi-onal headlights on the engine hood complementing the two big head-lights incorporated in the radiator grille. The blade and the rear ripper have very nicely detailed hydraulic pipes and details with a 360 piece limited run of the dozer issued in white for Roy Ferguson along with the standard release in yellow. The-re are no records of Allis-Chalmers ever producing a series in white but it is possible that such a paint scheme was ordered by a construc-tion company. The model seems to suit the white color.

The set with the HD-21 and the ejector scraper trailer is only available in yellow with the blade and rear ripper missing, but the hy-

draulic cylinders are shown in the correct secured position. Instead of the rear ripper, four hydraulic lines can be attached and linked to the scraper. The model of the scraper is based on the well known moto-rized TS300. A steering axle with a drawbar is used instead of a driving unit and steering is made possible with hydraulic power.

The model is a great match with the HD-21 but is a product of a vi-vid imagination.

A scraper trailer with hydraulics of that size was never produced by Allis-Chalmers and the closest match to the model is the wire rope controlled type 315 scraper. Besides that, the model is finely detailed, fully functional and goes very well with the HD-21 dozer model.

This leads to the obvious questi-on for the collector, when can we expect the HD-41 to be produced in 1:50 scale and, with the scraper head of the TS300, will a TW300 bottom dump wagon be produced? Can we also expect to see the who-le A-C series in 1:87th scale?

Roaring Sixties


It is a great challen-

ge to build a diorama

at any given time, but

even more so when

the time pressure of

a dead line looms. It

is also an opportunity

to try out some new

techniques….


A diorama depicting a scene from the formative years of

a firm had been ordered. The time allotted for construction was two months, including two weeks for mailing the parcel abroad.

An old photograph with a const-ruction scene was to be the guide.

The two main elements were an old excavator and a water pump, the rest of the diorama could be “free-lanced”. The model of the pump was a high priority item, since the firm in question specialized early on in hydraulic engineering (groundwater). The two men in the foreground of the picture had to be


included as well, since one of them was the founder of the firm.

The model of the excavator was soon identified, the picture show-ed Ruston Bucyrus 10-RB. It was ordered from Peter Sainsbury, Chatham Toys and Models in a scale of 1: 43. It is available in four different stages of weathering, new, light use, medium use and heavy weathering and dilapidated. The completed model arrived within four weeks, in the mean time a Menck M90 by NZG was used as a stand-in; both models have about the same measurements.

The Diorama

Since there was not a lot of the actual building site visible on the picture, a sketched proposal of the diorama was sent for approval. Ha-ving received the go ahead the fun started. Since the finished product was sent by mail, the finished dis-play should be solid but also not too heavy.

The base was made from a pi-ece of composite board with two large cut-outs to reduce weight. The frame, made from thin ply-wood was then screwed to the base with the resulting box proving to be very solid. The frame was then

filled with several layers of Styro-por used in construction. This ma-terial can be easily cut and shaped with a knife and saw except for the nuisance of tiny little balls of Sty-ropor floating around everywhere. Two layers of plaster bandages made a good foundation for the application of the base modeling compound. The one used on the project came from Busch, but is hard to find at the moment due to quality control problems with the manufacturing process. It is im-portant that when the surface coat is still wet, damp ground clay in several sizes is scattered on. Now is the time to carefully print crane track indentions in the still damp surface. To take advantage of the tackiness, small details can now also be placed and pushed lightly in to the surface. Once the desired effect is achieved, the coat of sur-face “dirt” can be fixed with a mix-ture of strongly diluted white glue and water.

The Water pump

Once the base was well under way, the construction of the water pump was tackled and caused quite a head ache. There are some pumps available in the ship modeling side

Quick & Dirty


of the hobby but none seemed to be a good fit for what was needed. Also plans for such a pump seemed to be elusive. Finally, the solution was to build it right from scratch. “Scratch building” is a popular way to build models in the USA from bits out of the scrap box and bits from other kits.

Supplemented in this case with profiles and pipes from Evergreen Styrene and Brass wire bits.

A sketch of the pump was used as a shopping list for the trip to a

hobby store. Since the two people on the picture stood right in front of the pump, measurement could be taken from a 1:50 model figure to arrive at the size of the pump. It is important to constantly check the progress of the model by placing the details temporarily together be-fore final assembly.

The dead line approached fast and so the painting of the pump model and the weathering was done in one go. A dusting of fine color pigments was added to the still wet

model. Rust and several shades of brown besides black where used and dusted on at the appropriate spots. The photographs confirm the excellent results.

In Conclusion

Money and time constraints lead to some compromises, besides that however; the construction of this diorama was a lot of fun.




Payloader Tractor-

shovel no. 3100 from

Ny-Lint co. Illinois

By Robert Bretscher

The photos show a Ny-Lint pro-duction model, built in 1957

in heavy pressed steel and still in good working condition. The rub-ber crawlers are still original and in perfect shape which is really outstanding after 50 years exposed to the air… The nice tiny shape of this Hough replica even attracts my wife, so from time to time she

permits me to expose the model for a short while in our dining room (When no visitors are expected to visit). With a handle on the right side of the replica, the shovel can be lifted and to tilt the bucket, the-re is a hand lever to dump the sho-vel manually.

The model is in fact a replica of the Model 12 Payloader crawler shovel, built by Frank G. Hough co. from 1955 – 1960. It was pow-ered by an International Harvester UD 350 engine and was equipped with a ¾ cu yard bucket. It was said that sales of this Hough front sho-vel were low and sadly, not many survived as originals.

What takes a week of

excavating on a const-

ruction site is an easy

hours work for the

4100XPC heavy duty

electric mining shovel.

By Urs Peyer

Henry Harnischfeger was 16 years old when he emigra-

ted in 1871 to the United States. In 1884 in Milwaukee, he and his partner Alonzo Pawling from Chi-cago founded the firm of Pawling & Harnischfeger, better known un-der the initials of P&H.

P&H celebrated their sesquicen-tennial anniversary this year. Pro-duction of earth moving machinery began in 1914 with the Model 210. This excavator was powered by a gasoline engine and had a 1 cubic meter drag shovel. The first hea-vy duty electric mining shovel by P&H was manufactured in 1933. The model 1250WL, with a shovel capacity of 1.9 cubic meters and a total weight of 86 tonnes followed in 1937. These, the first large size excavators, already had the crowd motor mounted on the shovel boom and the twin rectangular dip-

per handles so typical of the P&H trade mark style. In 1963, P&H de-livered the first 11.5 cubic meter ex-cavator, the model 2100 weighing in at 354 tonnes for surface mining operations. This machine soon be-came the standard in the industry. A further milestone was reached in 1969 with the introduction of the model 2800 with a shovel capaci-ty of 19 cubic meters. With an im-proved dipper capacity of 39 cubic meters and a weight of 1079 ton-nes, the model 2800XPC is still in production today. One of the grea-test sales hits of P&H was the 4100 heavy duty electric mining shovel, produced for the first time in 1991. With its 45 cubic meter capacity bucket, it could fill the popular 240 sht mining dump trucks with three scoops. More than 120 units of the 4100 where sold by P&H up until Spring 2003. An improved version, the 4100A was introduced in 1994 with a further updated version, the 4100XPB, in 1999. The capacity of the shovel increased to 52 cubic meters and the excavator weight increased from the original 1088 tonnes to 1370 tonnes. Introduced in the summer of 2006, the model 4100XPC brought an additional 90 tonnes weight to the scales and de-spite the relatively small increase in overall weight, P&H was able to increase the shovel capacity to

64.8 cubic meters. Early in 2007, the first units left the factory for mining operations in North Ameri-ca and Australia.

The history of the 4100 series would be incomplete if we did not look at the huge mining operations in the Oil Sands of Northern Alber-ta. The first 4100TS was used by Suncor Energy in its mining ope-rations. To prevent the excavator, weighing in at 1350 tonnes , from sinking in the soft underfoot con-ditions, the Tar-Sand-models are equipped with special 3.505 meter wide crawler tracks. The capacity of the shovels is 44 cubic meters or 90 tonnes. Due to the abrasive nature of the material mined, the teeth of the shovels have a life span of only two days.

In October 2001 Syncrude recei-ved from P&H the first 4100BOSS ( B-Series Oil Sands Shovel). Since COSS sounds less attractive then BOSS, P&H branded the C-series Oil Sands Excavator as 4100C BOSS and Suncor got its first C BOSS in the Spring of 2007.

An important feature of the new C-series is the Centurion control system. Centurion coordinates and controls the electromotors of the excavator and with that, the move-ment sequences. This increases the productivity and the availability of the machine and, besides simplify-

ing maintenance, also lowers the cost per tonne of material moved.

Centurion allows automation of certain digging functions and has probably the potential of one day eliminating the operator comple-tely. Improved all around visibili-ty and increased comfort are only some of the features found in the C-series excavator’s new style cab. The redesigned access to the cab and the engine compartment offer more room and simplify service calls. The design of the control cab has the newest findings in ergono-mics applied and is fully climate controlled.

A touch screen and the newest in control levers lead to an increase in productivity and mitigate the long 12 hour shifts in the mining indus-try. Like in any other branch of the industry, surface mining is always looking for ways to cut cost per tonne of moved material.

Where as the 240 sht dump trucks were the top of the heap in the 90’s, today the 320 and 400 short ton dump trucks, including the Ko-matsu 930E, Caterpillar 797B and Liebherr T282B are tops. Ideally

such a truck can be loaded in three to four scoops and if it takes more scoops, then the excavator is too small or the truck too big.

That is why Bucyrus, Marion (ta-ken over by Bucyrus in 1997) and P&H continued to build bigger and more powerful excavators over the last decades. Today the top market segment is shared between the Bucyrus 495HR and the P&H 4100PXC.

It takes about seven weeks to as-semble a 4100XPC with all parts delivered on low boy trailers and assembled on site. The undercarri-age is 11.7 m in length and 10.5 m wide. The width of the standard size crawler tracks is 1.93 m or as an option 2.21 m wide ones are availa-ble. The upper structure is 14.4 m wide and, without the boom, 15 m long. 102 mm thick cables are sup-porting the boom. Four cables with a diameter of 70 mm are necessary to sustain the load of a fully loaded dipper with 188 tonnes. The coun-ter weight is filled with 192 tonnes of metal punchings. To operate the 1730 mm diameter hoist drum with ease, two electromotors with a combined power output of 1119 kW are needed. The boom moun-ted crowd motor requires 537 kW. For the loading sequence to be un-der 30 seconds, three motors pro-ducing 1119 kW, are used for the slewing movement.

The track motors require ano-ther 1074 kW. As with the diesel electric motors in the dump trucks, excavator producers have now switched from a DC to an AC pro-pulsion system.

Eye level for the operator is at 10.1 meters and affords a problem free view of the interior of the dump trucks. At the Goldstrike surface

mining site it takes three loading cycles for the P&H 4100XPC with the 56 cubic meter capacity dipper to load a Komatsu 930E .

To use the excavator, optimal loa-ding is left and right in a sequence. Once a truck is loaded, the next empty one pulls into the loading position. To achieve a loading goal of 7250 tonne/h 12 dump trucks are required. If all conditions are optimal the 4100XPC can reach an hourly output of 8150 tonnes with an average material density of 1800 kg/m3.

Barrik Gold Corporation

The Barrick Gold Corpora-tion operates several gold mi-nes in northern Nevada. At the Goldstrike surface mining site, four P&H rope shovels and 37 Komatsu 930E move 365,000 tonnes of overburden and ore every day. The mine operates 24 hours a day, seven days a week and 365 days a year.



CaterpillarF-series dump truck

At Minexpo 2008 in Las Vegas, Caterpillar introduced the 793F, 797F and 795F AC dump trucks, the newest models of that line. The 797F by Caterpillar is the biggest mechanical powered, rigid frame dump truck in the world, using the new 20 cylinder C175-20 engine as a power plant. The power out-put of the engine is 2983 kw/h and the truck has a loading capacity of 363 tonnes. Caterpillar and Mitsu-bishi partnered in the development of the diesel-electric motor for the 795F AC with a loading capacity of 313 tonnes. The generator is lo-cated near the rear axle assembly and is driven by the C175-16 mo-tor that produces 2535 kw/h. The same motor produces 1976 kw/h in the 793F model which has a loa-ding capacity of 227 tonnes. More than 300 units of the popular 793 have been sold since 1991 and pro-duction of the 793F and 797F is set to commence by the end of 2009.

Caterpillar D7E

During the Conexpo 2008 in Los Angeles, Caterpillar’s greatest sur-prise announcement was the intro-duction of its Hybrid D7E track-type tractor.The power plant for this 25.7 to 28.2 t dozer is a 175 hp C9.3 ACERT diesel engine. The engine is connected to a generator that supplies the motors with alter-nating current (AC). Because of this, the gear shaft and Torque con-verter are no longer needed and so the number of movable parts has been reduced by 60% The results are extreme manoeverability coup-led with fast work sequences and a reduction in noise level. Due to the high start momentum, the pro-duced power is available immedia-tely. To improve the forward view, the cabin frame column, muffler, lift cylinder and GPS antenna are all arranged in a straight line down the centre of the hood. (up)

Volvo forest machines

In the fall of 2008, Volvo un-veiled the new Feller Bunchers in Canada. The diggers that work in the local Swiss forestry industry have a processor head which is used to fell, remove the branches and cut the tree to size in one go. A Feller-Buncher is a hydraulic exca-vator equipped with a short boom and stick with a power saw head. It can fell several smaller trees at once (Feller) and collect them (Buncher) before putting them aside. The felled trees are then dragged to the log sorting area by a log skidder. The Feller Buncher can alternatively also be equipped with a different stick and proces-sor head. Then the name changes to Harvester Carrier. The new se-ries contains the models FB2800C, FBR2800C and FB3800C with the FBR designation being a zero tail swing version of the FB2800C. Both models weigh 29.9 tonnes without any attachments with the FB3800C bringing an additional 4.5 tonnes to the scale. (up)
