Excavator inside an egg

What came first? The excavator or the egg? This question is easily answered: the excavator of course! That miniature construction ma-chines are hidden inside children’s surprise chocolate eggs today is, for me anyway, a sure sign that construction machines are trendy, and could be even called “sexy”. Besides the four Case models shown by Ferrero Chocolates, other manufacturers are launching new product lines with a construc-tion machine theme. This proves that we collectors of construction machines are not nutty individuals with a peculiar hobby. New mi-ning equipment is offered for the children’s play room by Playmobil. Every year Lego Technic sets that contain all kinds of construction machines from excavator to crane and dump truck, that can be made to operated almost like the prototy-pe come to the market . Even Lego City is having a building boom.

That the above mentioned firms spend a lot of money on research to be on top of all the trends and want to make greater profits from their

product lines is clear. It is a wel-come side effect however, that the promotion of their product lines is also a welcome encouragement for younger enthusiasts, the collectors of tomorrow. Every article that I read promoting the importance of toys, even in the computer age, gets my applause from the side lines.

From a sweet surprise egg to an even sweeter surprise! How would you like to get an absolutely free excavator model! Thanks to the al-ways excellent co-operation with NZG, we are able to give away a Terex TC225LC in 1:50 scale to every new subscriber. Now you can double your enjoyment of BAG-GERMODELLE magazine, so don’t delay and soon, this first class model can be part of your collection, just for subscribing to our magazi-ne. This is a limited time offer and ends when supplies are exhausted.

Have fun reading the newest issue of BAGGERMODELLE!

GMTS Brinkmeier 1:50

GMTS has found a real niche market with the “Golden Oldies” series of historical dump trucks. The models are cast out of resin exclusively by Lion-Toys and aug-mented with plastic detail parts. The main parts are screwed to-gether to assure the stability of the models. The line which started as a trend a few years back with a mo-del of the Krupp AL360 has now been extended with the new model of the Henschel H-261. The pro-portion of the cube-like hood and cabin are well executed and the en-graved details are enhanced by the application of separately attached parts such as side markers, rear view mirrors, window wipers and door handles. The fitted windows that are even with the outer side of the cabin window underline the positive look of this picture-perfect model. The robust all-wheel drive undercarriage is also executed well and has good detailing. The axles are rigidly mounted; however the tires are true to life. The rims are fi-nely detailed and inserted correctly to the right depth. The front tires even have a different tire tread pro-file than the rear tires.

Fulfilling a request from many modellers, the bin of the Henschel H-261 has been made to dump rearwards,. The bin can be raised about 30º degrees once the front lugs under the dump truck bin are disengaged. If the model is to be displayed with the bin raised for dumping, the raised bin must be

secured in place. For this a small piece of scale wood could be used.

All models are going to be pro-duced in the various prototypically correct color versions and in a strictly limited series.

In a limited series of only 300 pieces comes the Liebherr HS 855 HD drag line excavator in the blue colour scheme of the Busker Com-pany. The model can, just like the prototype, be used as a crane or, equipped with a dragline bucket shovel, as a dragline excavator. In this configuration it looks al-most better in its blue colour coat. Busker is a Dutch firm over a 100 years old that specializes in civil engineering works, especially pile driving, and has several drag line excavators in its stable.

Richard Fowler 1: 50

If the car enthusiasts can tune up their chariots by adding magne-sium wheels and chrome to eve-rything in sight, then the same can be done now with our dump trucks. The English supplier, Richard Fow-ler, is offering a kit for new rims for the Cat 777 and the 797F by Norscot. The set for the rear rims only of the 797F is comprised of six parts (white metal) and also fits the 797 and 797B from NZG. The complete kit is made up of four rims, six tires in the Michelin sty-le and further tuning pieces for the rear axles (a pipe like cover) and

hydraulic tanks, rear lights cabin rack, air filter and additional chro-med tanks for the truck deck. The complete kit weighs in at 1 kilo-gram and the price is to be around £200 plus shipping and handling. All inquiries in English please to [email protected] (up)

For many decades road rollers were designed after the look of steam rollers. The very well-known and very nice model of the Hamm DL 10 is now also available in yel-low with red wheels.

Siku 1: 87

The small scale construction equipment fleet made by Siku got a nice addition with the release of the Volvo EW180C. This solid and complete excavator model is the perfect gift for “little” excavator model fans, and will be a presence of many collectors’ shelves. Mat-ching this release is a set consisting of a JCB 8250 V-Tronic tractor unit with a three-axled dump bin trailer with a two axle dolly. The tractor unit is so nicely detailed that it will be enthusiastically received, even from “grownup” collectors. The units have high play values due to their great functionality.

Kibri 1:87

For the first time the new relea-ses from Viessman also include items from Kibri. Two items, or Deko-sets, are especially designed for the construction site. They are the “Baustellenzubehoer”, or con-struction site detail set, containing nine items, from the wheel barrow

New on the market


to the Porta-Potty that no construc-tion site can do without. The other set “Baugeruest”, or scaffolding, has not only the parts for scaffol-ding on a construction site but also two wall segments.

Herpa 1:87

The new Actros MB 08 all wheel drive tractor unit has been released


and the Carmehl dump trailer, both in Herpa’s in house construction fleet color.

In Steinle’s attractive color versi-on is the three axled Goldhofer half lowboy trailer which is available for the first time behind an MAN TGX tractor unit.

Finally, with a load of new pipes including a huge pipe complete with tie downs and wedges, comes

the MAN TGX telescoping low boy trailer combination.

by Albert Schmid

Bolinder-Munktell is a subsidi-ary of the Volvo conglomera-

te. There the popular rear steering configuration was constantly im-proved and adopted to a construc-tion site use and so a new variant of a construction machine was born. Consequently, Volvo continued in the development up to the model BM LM 841 that was produced for six years starting in 1972. The po-wer plant for the four wheel drive 10 ton wheeled loader, a 112 hp Volvo D 50 B diesel engine, was considered to be sufficient for its needs. It was considered an “All-rounder” in Europe and was used widely. This was due to its capaci-ty of having many optional attach-ments available and the flexability in bucket capacity between 1.3 and 4 cubic metres.

Also in 1972, the model maker NZG ( Nuernberger Zinkdruck-guss) received a commission from Volvo to produce a 1: 50 scale mo-del of the BM LM 841. The model makers excelled in perfectly repli-cating the parallel lifting mecha-nism which is very delicate on the prototype. How many copies were produced in this first run could not be ascertained. The second run, pro-duced in 1998, was limited to only 500 pieces. There were some diffe-rences from the first run, namely a changed exhaust plant, green tinted glass in the operator’s cabin and a slightly lighter hue of yellow paint. By the way, when looking at the evolution of the wheeled loader, the BM 841 from Volvo, whose pa-rentage as a tractor was easily reco-gnizable, was the last of its genre. After that all wheeled loaders evol-ved into articulated machines!

Eye Candy

Volvo BM 841When the Swedish agriculture tractor manu-

facturer Bolinder-Munktell (BM) hit upon the

idea of “turning the unit” and adding a rear

lifting mechanism, the beginning of a incom-

parable career as wheeled loader had begun.



the Manfred Bauer collection. The R-35 from Conrad was one of the first models overall to arrive. Only in later years was the collection ex-panded to include the whole palette from R-10 to R-50 from EMD.

The green dump trucks are but one of the focal points of his coll-ection of over 1500 models. A great passion is the tracked loader from Caterpillar. These machines were the mainstay of the excavation in-dustry until twenty years ago. Of course it was a Cat 935B that was used in the construction of his own home. Not a surprise really, since the line up of Cat loaders including 995, 953, 983 and 977, graces a whole shelf in one of the cabinets.

When the offerings for const-ruction models was still somewhat limited the R991 (Conrad 2823/4) was the first Liebherr machine to ar-rive in the collection. More models from the German excavator and construction machine workshop followed and now are, when added to the Caterpillar model numbers, the most prevalent models in the collection. The crowning glory of the collection for Manfred Bauer is

the recently acquired R944C tun-nel excavator (NZG 808).

A fan of tunnel excavations

In his practical time on construc-tion sites during his schooling to become a foreman, he experienced tunnel construction for the first time. The Vereina tunnel, the new rail connection between the Enga-dine valley and the Unterland, was one of the projects he was involved in while working for the firm of Lazzarini. Later, he encountered a tunnel milling cutter when working at a construction site for an access tunnel in a hydro generating stati-on. This experience left a deep im-pression on him. It manifests itself in a large display of models, star-ting with the Tamrock Jumbo drills from Conrad (2501) and HiMoBo, Drill attachments, tunnel loaders and tunnel dump trucks that are a fixed part of the collection in the stair well.

Additionally, in the basement hobby room, a tunnel boring ma-chine is under construction using Polystyrol profiles. The model is

by Daniel Wietlisbach

About thirty years ago the collecting passion began for

Manfred Bauer as he purchased his first models with his minimal apprentice’s salary. The price of each of the models, between 35 and 45 Franks, was about a quarter of his total monthly income. Re-maining from this early collection are the Caterpillar 955 (NZG 115) as well as the O&K RH40 (NZG 188). However, Bauer’s love for construction machinery goes back much further. Since his childhood, and on his own accord, our collec-tor hung out around construction sites for hours at a time and was fascinated by construction ma-chines. During his school time he often arrived home with dirty or completely torn trousers much to his mother’s annoyance. The rea-son for this was that he frequently visited the gravel pit which was managed by the father of a friend. There he and his friend had the op-portunity to get rides on one of the Euclid dump trucks in use at the time. The seating available was the lid of the tool box as the old truck’s Spartan interior did not provide a seat beside the driver’s seat.

Multiple focal points

it is not surprising, therefore, that there is a whole row of “Eucs” in



1:50 scale and fully detailed, we will have a more in depth report about this model at a later time.

After concluding his education the freshly minted foreman retur-ned to the Engadine valley, but his work was mainly on civil enginee-ring building sites. Only rarely was he involved in below ground work. If the work in underground tunnels would have been more conducive to family life Manfred Bauer would love to have pursued it further. However, just before his return to the mountains and valleys of the Engadine, he met his future wife, Esther, and the die was cast.

The first present for his wife still sits on her night table in the be-droom. It is a Liebherr R952 from Conrad (2826)! That he is able to display a great deal of his collec-tion in the bright space of the stair-well, is a great testimony of the to-lerance of his spouse for the hobby. For his 40th birthday she gave him the dump truck Terex Unit Rig MT 5500 form OHS, a super model perfect in every detail.

The rarest model in his collec-tion is the Broyt X4 with a general purpose bucket (NZG 118).

At the moment Manfred Bauer is searching for an DJB 275 articula-ted truck from NZG (166) as a ad-junct to the articulated dump truck DJB 300. As a caveat the collector adds that he is not prepared to pay the highly inflated prices on eBay that this item brings. It may well be that he can acquire the missing model from a fellow collector in a swap deal or for other considera-tions. From his own experiences he knows that such a deal needs a great deal of nurturing and negotiating. About a third of all his models are still sitting in their original boxes. All his tracked cranes for example, since there is just not enough space to display these fascinating objects.

Contacts andscratch built models

Manfred Bauer is a long time member of the Modelbauklub Wy-land, a club of plastic model buil-

ders. With his tunnel boring machi-ne is he an exotic exception, along with one bridge building member, to the mostly military modeling members. The very time consu-ming construction of the tunnel boring machine, on which every detail including all the hydraulic li-nes has to be perfect has caused the building of a Euclid R-22 in 1:25 scale to remain in limbo. The large scale of the Euclid was chosen to incorporate an existing model of a Cummins engine from an AMT kit. The dump truck will be great companion to the Caterpillar D-9 models from First Gear. Alongside these exotic models there are a few in the smaller 1: 87 scale. They are mainly from Kibri, among them the well known construction crane models displayed on Bauer’s mo-del train layout.

Other modellers may know Man-fred Bauer as a dealer and a writer on the Internet site: Bauforum 24. Often first contacts in the forum lead to face to face meetings at ve-nues like the Bauma exposition.

The collector

Manfred Bauer is 44 years old. He apprenticed first as an architec-tural drafter after which he took a brick layer’s apprentice ship. Fi-nally he learned how to become a foreman. Today he works for a general contracting company as their construction site foreman.

As well as his machine collecting passion he is also interested in model trains, and in his spare time works for a German model train importer’s Swiss warehouse.

He is married and lives in Diessenhofen. The couple have three children, ages nine, eleven and fourteen. The oldest, Christian, is also interested in construction machines and owns a few models himself.

After a lengthy and intense de-velopment period Caterpillar

finally presented the model 225 in 1972 weighing in at 23.9 ton-nes. Two years later the model 235 and 245 appeared on the market with a weight of 39.9 and 95.7 re-spectively and to complement the line-up, the model 215 was added in 1976. Until the replacement of the 200 Series with the 300 Se-ries machines in the 90s, Caterpil-lar sold these machines in a B, C and D configuration. The 225 and 245 were never offered in the C configuration. Between 1983 and 1984 Caterpillar supplemented the line-up of tracked excavators with models originally produced by the Eder Company. They are the mo-dels 205, 211 and 213 with a wor-king weight of 13.1, 15.5 and 17.3 tonnes respectively.

In the early years these excava-tors where also unofficially known as” Eder pillar” excavators. In 1986 and 1987 with the models 229 and 219 a further two excavator models joined the ranks with weights of 21.1 and 29.1 tonnes. As a late co-mer to the line, the 34.4 tonne hea-vy model 231D excavator rounded off the Caterpillar offerings.

Produced for 20 years

The Cat 3406 six cylinder diesel engine with exhaust turbine and an

output of 325 was used as a power plant for the A series. Depending on buyer specifications, the ex-cavator could be equipped with a 3200 millimetre or 4420 millimet-re jib. Together with the 7925 mil-limetre long mono block arm, the maximum depth achievable was 8.7 meters and 9.7 meters respec-tively. Four different buckets were offered with a capacity ranging from 1.6 to 2.5 cubic meters. The face shovel model 245 with a capa-city of 3.1 cubic meters was added in 1976 and the unit had a weight of 64.6 tonnes. The third hydraulic cylinder (master cylinder) enabled the automated steering of the scoo-ping buckets. The cylinder pumped oil into the bucket dumping valves so that the bucket was always kept at the same angle when dumping. In 1976 the look of the cabin was re-engineered. The pointed front of the cabin with a two part window was replaced with a straighter front window. In the middle 80’s, Cater-pillar extended the line to include the ME and Deep Trenching units.

The ME mass excavating model had a maximum capacity of 5.2 cu-bic meters, thanks to a special bu-cket and special boom with a shor-tened jib attachment. With a longer boom and a heavier, 4.6 ton counter-weight, the canal excavator or deep trenching unit was delivered with a 390 millimetre longer carriage and an operating weight of 72.1 tonnes.

The A version of the 245 with the old “C” logo was built by Caterpil-lar until 1988, with the proviso that the last machines produced in 1980 were to be branded with the new logo (machine model number in a black stripe) when delivered. With the logo change came the updates to the B series. With almost the same operating weight, the output of the power plant was increased to 360 hp. No sooner had the Cater-pillar customers become adjusted to the B-series than it was replaced by the series-II models. To spot a series-II model you have to look at the place where the air filter sits. It is slightly higher on the II-series models. Again the logo underwent

a change: the model number mig-rated from the black stripe on the rear to the yellow side shrouds. For the first time the type 245B LC ap-peared in a model with a lengthened chassis. Only four years after the B-series, Caterpillar brought the D-series to the market. The weight

of the new machines, depending on the model chosen, varied between 67.9 and 75 tonnes. The perfor-mance of the 3406B motors was engineered to produce 385 hp now. As a lead over to the 200-D series, the same logo was utilised, a smal-ler red stripe on a black stripe. The

model number was again in white on the black stripe. Since the mo-del 245D excavators were produ-ced for only a year they are a rare sight in Switzerland. For almost 20 years the 245 model was on the market until it was replaced with the 375 in 1993.




CCM had planned that the Cat 245 was going to be the third

die-cast model in a series of his-torical Cat machines which it was going to produce. The delays and the long wait over the last few ye-ars has been a great trial to the pati-ence of many collectors. The parti-ally unexplained delays, the many postponed release dates and the preference for producing the D10 model first, did cast grave doubts on the appearance of the Cat 245 model. Some naysayers even sug-gested that it would not be produ-ced at all.

Two and a half years after the first announcement, both backhoe and shovel versions have been re-leased. We have, as always, che-cked the major measurements: length and width of the under car-riage and upper carriage as well as transport height and length and are concurrent with the measurements we have from our records.

Undercarriage

The very substantial under carri-age gives a good impression. The driving wheel has the characteristic three holes and the guiding wheel,

with help from a lightly sprung suspension spring, puts light pres-sure on the tracks so that they can move freely and without binding. The three guide wheels are mo-deled, the support wheels, mostly invisible anyway, are only hinted at. The shovel version of the exca-vator is equipped with the standard width track segment size of scale size 610 mm; in comparison the backhoe version has segments of 950 mm scale size for its tracks for a reduced ground impact. Each track has 51 segments and is made, as usual, from metal. As with the prototype, there is an additional counter balance weight carried bet-ween both track sides.

Upper carriage

The upper carriage of the model has some very nice details, how-ever they will give rise to some

criticism from collectors. We wel-come the see-through air grills even though they are somewhat more robust, probably to prevent breakage. The limits for manufac-turing large grilles like these pose challenges to die cast manufactu-rers. As in the prototype, the lids for the fuel tank, hydraulic fluids tank and the cooling system can be opened and are accessible from above. The equipment in the ma-chine room, seen through the grill, can be more imagined then clearly seen. Fortunately, the rear doors can be opened, allowing a mock up of the motor and hydraulic pump to be discovered.

The second series cabin is the one chosen for these models and features a one piece front window neatly inset and without any gaps showing. Since all the windows are made from one plastic piece, the side windows are set too deep

long time for the arrival of a contemporary

in to the openings and show the off thickness of the casting unfa-vourably. This problem had been perfectly solved with the D10 mo-del. The sky light is too large when compared to specifications. It is less glaring in the general purpose version.

The see-through side walk-ways on both sides of the upper carriage are cast very finely and all hand grips and rails are free- standing and have been mounted separately.

EquipmentThe shovel version is very nicely

detailed. There are six hydraulic cy-linders with all the associated lines which are, for the most part, free-standing and give the boom and jib a very finely detailed look. Where the lines are moulded on they are of a good size and stand out well. There are two hydraulic cylinders moulded on to the bucket with a hinged bottom lid. The piston rods are not modeled but they would be invisible most of the time anyway.

The backhoe version is shallowly engraved, as in the original. Howe-ver, the hydraulic lines, simpler on this version than on the prototype, are moulded on much too shallow-ly. This is especially so for the hyd-raulic lines on the boom. The over-all look of the boom and jib though are pleasing to the eye.

The paint job and lettering with the “Pacman” logo for this model are faultless and underscore the look of this model of a legendary machine.

Compact, quickly assembled, large extensions capable of lif-

ting a heavy pay load are some of the criteria that make a great mobi-le crane. This relatively new genre of crane is enjoying an ever- incre-asing popularity. After its success in the real world, mobile cranes have now started their triumphant march into the collector’s world.

Mobile on four axles

Starting with the undercarriage we can find one of the first impro-vements Conrad has made. The support arms are no longer made from plastic as in the past. On this new model they are made of pew-ter. Due to this fact, the MK88 is much more stable than its mate the MK 100, whose supports are made from plastic. As a bonus, Conrad has included small crane mats with this model improving the look sub-stantially. During the transport of the crane these mats are carried on the side of the crane at a specified place and do not just lie around- a really well executed detail. It goes without saying that the model is a smooth runner and so it passes the test on this score too. All four axles

are steerable and give the model a tight turning radius. An absolute novelty is the warning lights. They have a built in flashing unit! The motor that produces 300 kW/h is located between the radiator and the tank. Cleverly disguised under a lid are the three small button type batteries that power the lights for the flashing beacons. The covering over the cabin is easily removable and this is where the minute toggle switch which turns the unit on and off is located. A real classy act.

The upper carriage

Conrad lavished the well known adherence to detail on the upper carriage. The silver slip sheets are the first thing the eye notices. An optional railing can be added to the cabin side. Also optional is an ad-ditional counter weight that can be added to the crane. In the prototype this would weigh up to 2 tonnes.

There are three winches in the upper carriage housing controlling

cing the very well done model here.

the movements of the crane. The rear winch is already pre-wound and secured against moving with a clamp. The front winch is the larger one and it controls the cargo hook. The remaining winch is for the erection of the lattice tower. It has no rope on it in the model box. On the picture shown, some rope from the modeller’s scrap box was used and wound upon the winch. The lifting winch however, has enough rope on it to use it for the erection of the tower segments. It is com-mendable that Conrad has used all metal pulleys on this model. The pulleys are all separate units and run smoothly. In comparison to the MK100, the tower for this unit is of a lattice construction type, and made very durable by Conrad. However, it lacks the ability to use the winch for telescoping the to-wer. On the front of the tower are some small posters that give infor-mation on the carrying capacity. It is very easy to extend the tower up to the maximum of 58 centimetres



measured at the hook and to secure it with a plastic bolt arrangement. On the one side of the tower are a ladder and a cabin. The cabin can be re-positioned along the tower assembly using a dedicated winch.

The boom is long and yet compact for transporting

The boom length extends to 88 centimetres or 45 metres in the prototype. The construction of the arm is extremely complicated as it contains three joints and many sup-port struts. During the transporta-tion process, the jointed boom sec-tions are folded and tightly stored

against the main tower structure to make a compact unit. The erecting process starts by folding down the front piece of the boom using the winch in the upper part of the to-wer assembly. Now, operating the winch slowly, the whole boom pa-cket can be unfolded and brought into the horizontal position. The lifting rope uncoils automatically since there are no arrest stops at the winch. The trolley remains at the front part of the middle section of the boom during transport. Its position is such that the tip part of the boom is exactly above it and so contains the hook safely. This saves a lot of space. As in the pro-

totype, the middle suspension guy wires are made from a thin steel wire. The trolley can be moved with ease along the extended boom and is, like the hook, equipped with metal dollies. The hook can be lowered effortlessly without a load attached.

All in all it can be said that the MK 88 presented by Conrad is another mobile crane that impres-ses with a great amount of detail and great functionality. It is hoped that we will see the new metal sup-ports and metal dollies used in fu-ture Conrad models.

Die Schwerlastspe-zialisten: Scheuerle, Nicolas, Kamag

Stefan Jung / Michael Müller, published by Podszun,170 pages, 450 pictures,size 21 x 28 cm,ISBN 978-3-86133-557-3

The TII group is the world’s largest supplier of heavy duty vehicles and special vehicles. With sister companies Scheu-erle, Nicolas and Kamag, TTI offers a wide re-aching palette of vehicles for special transportation challenges. The history of the three companies is detailed by the authors with the pages on Scheu-erle making up almost two thirds of the content. Some of the more histori-cal pictures are awe inspi-ring, especially so since a good number of them are from Switzerland. Among them, for example, is the transportation of a com-plete P&H 1055 loaded on a four-axle Scheuerle trailer. The bucket shovel is carried on a separate unit. The transportation of a Liebherr R998 on a self propelling SPMT in Australia also leaves one breathless. (dw)

Schwerlast in der Schweiz ( Heavy loads in Switzerland)

Wolfgang Hauch / Konstantin Hellstern, publishing by Pods-zun, 160 pages, 345 pictures, size 21 x 28 cm,ISBN 978-3-86133-555-9

„A small country with

big transportation chal-lenges“. This slogan would sum up the book before us nicely.

The most important heavy load transportation firms, including Abächer-li, Sarnen, Zwissig and Sierre and their vehicles and cranes are listed in alphabetical order. They are accompanied by text and pictures. This catalog is made more interesting by the inclusion of por-traits of heavy duty load specialists and suspense-filled actual accounts of heavy duty transport chal-lenges. For example, the transport of a wind turbi-ne to Mount Soleil during the time when there were no mega windmill trans-porters or LTM 11200 yet invented. Additional reports are of the typical Swiss transport of hydro electric turbine parts for power stations, tunnel drill rigs and the not too uncommon transport of spectacular construction machinery.

Baumaschinen Klas-siker ( Classical Con-struction Machine)

Christian Suhr, Ralf Weinre-ich, publishing by Motorbuch, 159 pages,ISBN 978-3-613-03098-5

The team of authors of the volume in front of us looks at 15 select, classic construction machines.

Each one is featured with pictures and a de-scription (the main em-phasis of the book is on the pictures )

From the dump truck sector, the following machines are included : Krupp MK17, Volvo DR860, Kaelble KK50. The choices from the ex-cavator department inclu-de: Menck M60. Nobas UB1212, Fuchs F301 and Zemag RDK300-1. Addi-tional reports cover a Cat D8, a Russian T100 dozer, a Cat 988A and a Hano-mag B11 wheeled loader. The sometimes double-sided pictures are mostly taken by Ralf Weinreich himself. Among the con-struction machines cho-sen are some from the former East Germany (DDR) which are almost unknown here. The texts acompanying the pictures are informative and well written. (up)

Ulrich Biene, Delius Klasing Verlag, 192 pages,21,5 x 30 cm, color pictures, text and illustrations,ISBN 978-3-7688-3168-0

There are over 1700 outstanding pictures in the third book covering Wiking models. Many pictures cover all the va-riants of a single model.

The last instalment of the series about the Wi-king Company concen-trated on the history of the firm while this new tome is dedicated to the collector. It tries to create the excitement of collec-ting this legendary ma-ker that is always present when collectors gather.

The first seven chap-ters, each dedicated to a decade, focus on the de-velopment of the models. In the second part the fo-cus is on the themes that collectors choose: any model connected with flashing blue lights, the Post Office, agriculture and of course the const-ruction industry.

The old and honoured old Menck excavator is described as a back hoe excavator. This is a mi-nor fault for which we can forgive the author wi-thout a qualm. Other than this small glitch, the book is extremely well written. (dw)

Bauer RTG RG 21 T from Bymo 1:50

Europeanby Daniel Wietlisbach

The firm of RTG Rammtech-nick GmbH is part of the Bau-

er Manschinen GmbH conglome-rate. This is why, even without the typical Bauer machines blue paint scheme, it has a Bauer machine familiarity. The RG 21 T is a ma-chine in the 70 ton class. The ‘T’ stands for telescoping mast. The original machine achieves a maxi-mum height of 26.8 meters and can be used with a great many attach-ment options. A variety of vibra-tors, presses, drills and several op-tions for soil mixing attachments are available.

After making many exquisite models in China, Bymo moved the production lines to Bosnia in the former Yugoslavia for the RTG model. “We wanted to be closer to the production line” explains An-ton Harrieder from Bymo.

The model pleases at the first look and checks out against the measurements of the real thing. With the telescoping mast fully extended it reaches a height of 56 centimetres or 28 meters in reality, the original height. All other basic measurements are correct to scale, in both loaded and working set up.

Undercarriage

The undercarriage is equipped with two telescoping track carri-

ers. They have a minimal “give” and are responsible for the neces-sary stability. The metal tracks, the only parts made in China, are made up of 51 three part links for each track. Because of the use of a very tight spring attached to the lead guide wheel, they are not very easy to move. Especially nice tou-ches are the four, open grill steps attached on each side.

A special challenge was the con-ception of the upper body housing. On a first look, the upper body looks reasonably flat but a second look reveals the many details ne-cessary here. Many large air intake grills have been stamped on, but have not been painted differently from the body to make them stand out. Perfectionists can use some di-luted black washes to bring out the detail here. Heavy construction en-thusiasts are going to be impressed by the fact that the counter weights can be removed as in the prototype, to reveal the correct weight attach-ment mechanisms and fastenings.

The operator’s cabin sports a two color interior. The windows have a simulated rubber gasket painted black. The side windows are inser-ted from inside the cab. The front window is set seamlessly into the cabin housing and the sky light is protected with a finely etched grill. It is left to the modeller to attach the grab irons and cabin step as well as a ladder with a rear view mirror for the machine house side of the unit.

Telescopic leaderand equipment

The Parallelogram kinematic lin-kage system allows the mast to be kept safely in the fully extended position. To translate this into mo-del form a mix of metal and a new, special, very light weight plastic compound was used. From the distribution box on the upper body section no fewer than ten fine and flexible lines are connected to the leader and equipment on the mo-

del. This is why the missing hyd-raulic lines are not obvious at first glance. Four lines lead over guide wheels from the head to the vibra-tor. The auxiliary winch is a dum-my. The vibrator, type MR 105 V/ MR 125 V, is finely detailed and, like the prototype, movable. For transportation purposes it is made removable as in the prototype. The sheet piles, two of which are inclu-ded with the model, are attached to

the vibrator with a fine chain. The scale length of the sheet piles is 10 meters. This makes it possible to display the machine with the piles driven partly into the ground. The sheet piles are also available sepa-rately in a set of five.

In Conclusion, the finish

The satin paint finish is clean and covers the model well with some

traces of paint running in the fine grooves of the model. The lette-ring is crisp and no paint shines through. It would have been nice to include some warning labels for the modeller to add.

The model is good value for mo-ney and will bring change and inte-rest to any collection that speciali-zes in civil engineering machines. Bymo’s premiere in Europe can therefore be called a success.



by Urs Peyer

Caterpillar built its first 657 twin motored scraper unit in 1962.

Even then, a fully loaded and he-aped scraper bucket had a capacity of 33.6 cubic metres. At first, the power plant of the 657 produced 785 hp and this was considered suf-ficient. The next model, the 657B, increased the power available to 950 hp. In 1982 the model line was updated to the 657E. The G versi-on has now been on the market for about three years. The tractor unit is a C18 and the Scraper a C15, with a power output of 1051 hp in third gear. Despite its total weight of 119 tonnes the 657G PP reaches a speed of 55 km/h on a level track. PP stands for Push-Pull and de-scribes the configuration that two scrapers support each other’s ef-fort thru one unit pushing and the other pulling. A huge power effort of 1948 hp is thereby applied to the 3.9 m wide cutters enabling the loading of the scraper train (36 me-tres in length) with 2 x 33.6 cubic metres of material in a short time.

Overflow protectionand waste ejector

The biggest problem with the model is that the overflow protec-tor and the waste ejector are moul-ded as one non-functioning unit. To disassemble the unit, the two

screws on the bottom are removed. Using a fine saw, the unit is cut in two parts. To bring this part closer in detail to the prototype a dia-mond shaped hole plate is glued on the inside. Photo etched hole plates are not cheap but look superb. For this project a 3/32 diamond shaped hole plate from Special Shapes out of the U.S. was used. The waste ejector is made from ABS profiles and sheets from Evergreen. The measurements, thickness and ang-les can be taken from the discarded piece. Since the construction of a fully functioning ejector would re-quire a massive change to the rear portion of the bucket, and, because of the tires, would not be seen any-way, the replacement is merely a dummy. Both ejector cylinders and the supports can now be installed when the rear wall has been positi-oned at its extreme extension. Use caution here as nothing is level in that area of the model.

After removing both of the old ejector brackets and filling the holes with two part epoxy the bu-cket floor looks as it should. The removable floor plate underneath the rear motor is cut into two at the place of the first screw hole. In the front part of the cut plate a square hole (20 x 19 millimetres) has to be filed out. The rear part can be re-attached without modifications. The front part is glued to the rear end of the scraper bucket bottom.

Scraper bucket

After filing off the inner lip, the four bolts that hold the apron and the suspension of the bucket should be carefully removed using a fine pin punch. (Caution! The bolts have to be re-used) The way the lifting cylinders are mounted on the bucket is incorrect and has to be changed. To do this, remo-ve both of the brackets, fill in the

Detailing a Caterpillar 657G from Norscot

California StyleShortly after the original appeared on the

market, Norscot brought out a model of the

a bit better.



holes as per the earlier instruction, and make new brackets out of 1 millimetre aluminum sheet on the cross brace for the two piston rods. (To make it easier to glue the bra-ckets on, make some lugs on the backside)

When observing a scraper in operation in California one cannot miss the side boards attached to the buckets. This allows the operator to load more dry or sandy waste material. In this case the height of the side boards is 70cm or 14 mm for the model. These extension boards are also constructed using ABS profiles and sheets. Before adding the extensions the top of the scraper bucket has to be filed down flat. Due to stability issues the extension boards are glued to the overflow protector. The projec-ting angle profile is there to protect the side arms from material spil-ling over.

Diesel tank and rear motor

After removing two screws the tank and the motor cowl can be removed from the radiator. With a gentle pull the exhaust pipe and air intake can be separated from the engine block. The air filter at-tached to the air intake pipe is cut off with the saw but retained as it

is re-attached later on to the motor block. The result is that the three pieces can now be spray painted se-parately. A new fuelling intake line made from 1 millimetre brass wire is added to the right side, so that our driver no longer has to climb on the top of the rear engine.

The radiator protection grid and the hook of the push/pull assembly have been glued on at three places and can be removed using a centre punch tool. In order for the front bar of the rear scraper to fit into the hook assembly properly, the inside of the hook needs to be enlarged slightly using a 3mm round file.

The hand grabs attached to the side of the radiator assembly can be made functional by opening them up with a 2mm milling cutter. The cast-on hand grabs on the cowl are replaced with formed 0.8mm brass wire.

Handrail

Since even the newer 657G with the new logo does not have Black Hand rails all hand rails on the model are yellow. If you have the necessary soldering skills you can make your own to replace the ones on the model.

The wheeled loader

“Giant” from Gama

has many similari-

ties with the Kaelble

SL600. It is also just as

robust as the SL600.

by Robert Bretscher

The wheeled loader without a motor (Article number 8100)

made in 1964 by Gama was a mo-del toy suitable for sandbox duty. The robustly constructed loader with steering, huge tires and a pen-dulum axle was ideal for the hard

work out the model got in the sand-box. The lifting mechanism was operated with a crank and could be lifted and lowered smoothly. The bucket shovel could be emptied with a simple dumping lever.

This large steel model was pro-duced in several versions. The first series was equipped with rims made from tin; unfortunately, later models got flat plastic caps instead.

Gama also offered a crane at-tachment for the loader. It had the option of a grappling hook for the crane (not shown in the picture). The front loading bucket had to be removed to mount the crane. Such a crane attachment could be found in the 50’s on the Polytrac wheeled loaders manufactured in Germany.

It was a lot of fun to

build this shoring wall

out of brass channels

and scale wood, even

though it took longer

than expected to com-

plete.


Actually the project called for a bulk head profile wall,

but fate intervened. After a long search for suitable detail parts for the project and some aborted tries to make such a wall from plastic profiles the appearance of a new model made all the difference. At the lowest ebb during my scratch building attempts, NZG announced the production of the Weserhűtte W180 with pile driving attach-ment. This gave birth to the idea of using a Berlin shoring system wall, also known as Traegerbohl wall in the trade. The Berlin shoring wall system got its name from the tech-nique used in the 1930’s in Berlin during the construction of their subway system.

Since the thickness of plastic profiles was too thick, some brass profiles were ordered for the be-ams and horizontal carriers. It was

not an easy decision as I was quite comfortable working with plastic products and the thought of mul-tiple soldering jobs was not exact-ly thrilling. The results, however, are exciting and worthwhile. The shoring walls have become the centre piece of the diorama. The walls also divide the diorama from the road above and also provide a great back drop for the models on display.

Sub terrain and beams

To avoid a tired look none of the lines on the diorama are straight! The planed road curves as it de-scends. The construction pit its-elf is on three levels. To have a background on which to attach the shoring wall, a solid structure had to be constructed. The pliable and yet sufficiently solid Balsa wood was chosen.

The brass H type profile, measu-ring 6 x 6 millimetres (For 1:87 : 4 x 4 millimetres) was cut with a saw to the desired length and received the prototypical hole at the upper end made with a drill to achieve the 1 mm opening (0.7 mm). The upper end was also carefully ham-mered flat to make it look like it had been driven into the ground with a pile driver. Not all profile pieces were cut to the same length. On construction sites the ends of-ten look uneven.

The brass pieces were then im-mersed in a chemical bath to brown them until they reached the desired degree of coloring. (It is extremely important to follow the manufacturer’s instructions as the-se solvents are very aggressive). Sandblasting is another method which could be used as it creates a slightly roughened surface to which paint adhere really well. The finished profiles were then moun-ted upright with two part epoxy glue, exactly 50 mm(30mm) apart. A model crane proved to be a great replacement for a plumb line. The distance between the H profiles was reduced to 40 mm (25mm) where an older house was to be built on the diorama.

Filling in withwooden planks

The planks used for the spaces between the profiles were made by Northeastern scale wood which is available in hobby shops. So that the scale planks did not look too new, they were roughed up a bit using a wire brush, taking care that not all of the wood was distressed to the same degree. This empha-sised the wood grain and once stained with brown-black from a very light brown to an almost black tone, almost every board had a slightly different hue. To prevent the planks from being too

loose, cardboard strips were cut to fit in between the profiles before the wooden boards were glued on at the workbench making the job much easier. (One can imagine the forces at play in a real life si-tuation.) Then cardboard and scale wood strips were weighted down until dry to prevent warping. These prepared strips were left unglued to

the profiles until almost the end so that when coloring and weathering the surrounding area, they would not be splattered with paints. The last row of planks was left loose so that they could be inserted just before blending in the surrounding terrain. Care was taken that not all of the strips of wood were of the same level horizontally; to achie-

ve this little bits of cardboard were used as furring strips to give each section of strips a different height. This makes it look more realistic and this is half the battle in a Di-orama.

The next instalment in this series describes the fabrication of the gir-ders and the necessary soldering of 120 joints.





The river Rhone, or Rotte as it is known in German dialect of

the upper part of the canton, carries a lot of gravel in its flow. To prevent flooding the gravel is excavated at many places along the banks. For-tunately, river gravel makes excel-lent class building material. To get at the gravel, first class excavators, especially drag line excavators are needed.

Prototype

The SW 190, with the factory number 190117, was originally built without an undercarriage and was used at the Weserhütte works in Bad Oeyenhausen as a test ma-chine. At the works it was mounted on a concrete foundation. In 1989, equipped with a new undercarria-ge, the excavator ended up in the Wallis. The unit was used by the Theler AG, a specialist in civil engineering and underground pro-jects. At first it was equipped with a ram head for pile driving opera-tions. For this the lattice boom was altered to accommodate a double dolly roll head. With a drilling at-tachment from Casagrande it was used to drill holes for support piles. The SW 190 turned out to be a real change artist, being used in many different roles, until it was transfor-med into the drag line excavator in

2002. At that time it was sent to the concrete works in Raron with the original drag line scoop and boom. Lately, a telescoping undercarriage equipped with three rimmed skid chains to improve the stability of the 55 ton excavator was added. Sheet metal extensions were wel-ded on to the bucket to increase capacity to 2.5 cubic metres. The empty weight is 2.1 tons.

A first class machine

Since the Cat 6 cylinder D 3306-T was used in the SW 190 and has been well maintained it starts up without making a lot of noise. The water cooled engine produces 180 hp (133 kW) The letter S in the excavator’s type designation si-gnifies that the machine is a rope line (Seil, in German, for rope) This was done deliberately to em-phasize that it was not one of the new hydraulic excavators coming on to the market at the time. At the

same time though the series SW were the first drag line excavators to partially use hydrostatic drives. The boom winch and the swivel mechanisms are equipped with the then new drives in the SW 190.

At the time, Weserhütte did offer an all hydrostatic drive unit with the designation SW 190-H.

To get a perfect picture and to please the photographer, who had asked for “close the door please”, driver Gery Bregy complied and accepted that the sun on this lovely autumn day would add a few extra degrees to the temperature inside the operator’s cabin. The manager of the concrete plant operates the unit only when needed, despite the fact that he really likes working with the excavator.

During a work sequence the well maintained machine shows what it is capable of. Gery Bregy turns the upper carriage towards the river, re-leases the lift winch and the bucket shovel falls with a loud bang in to

the water. Right away the winch is stopped and the bucket disappears underneath the water. The drag line stiffens and the motor controlling the winch makes a laboured sound while dragging the bucket over the gravel bed. The bucket is now full of wet river gravel and weighs now about 6 tons. It is lifted out of the stream, and, after the upper carria-ge turns 180 º the load dumped by slackening the drag line. A single motor is sufficient to turn the unit back and dump the bucket 20 met-res away in to the river.

Manager Max Theler and dri-ver Gery Bregy both express their great satisfaction with the operati-on of the machine.

A lack of skilled operators

Despite being satisfied with the machine, a hydraulic excavator was bought in 2009 as a replace-ment. On the wood paneling of the railroad bridge nearby some damage was noted and the railroad claimed it was caused by the lattice tip of the SW 190 excavator. The railroad demanded that, after their insurance paid for a multi-million franc repair bill, the company stop using the unit or pay up. To escape the punitive financial measures,

the decision was made to replace the old unit.

The performance of the SW 190 can stand up to the newer Cat 330C hydraulic excavator with no prob-lem. The Cat can do three work sequences in the same time as the SW 190 takes to finish one, howe-ver, the bucket of the cat can hold only about 700 litres, less than a third of the capacity of the SW 190s bucket. Despite this the new excavator will prevail over the old unit, mainly because every dump truck driver can, if need be, load his own truck with the machine.

To operate the dragline excavator in comparison requires a trained operator. There are now only two machinists left at Theler AG that have the ticket required to operate the excavator. For this reason the old excavator will be moved to the construction yard of the company were it will wait for other const-ruction assignments.

Hover Track 42-44For phase one of the extension of

the Rotterdam harbour, 230 million cubic metres of sand were required as fill. In order to prevent the ocean reclaiming the newly created land area, it was necessary to construct a 2.4 kilometre long shore line pro-tection. The wave breakers were constructed using over 20,000 con-crete blocks each weighing between 40 and 46 tonnes. To transport the blocks from the factory to the shore line, three special transport trailers were designed and manufactured by the Dutch firm of Veldhuizen. A special clamping mechanism secu-red the blocks individually. Thanks to the 85 centimetre wide tires, the 3 kilometre long trip wasn’t a prob-lem. The tractor units used for the-se vehicles are the 13 ton Hover-Track 42-44 tractors. The chassis is from an Iveco Trakker, the cabin from New Holland and the power plant is a Euro-5-Motor producing 440 PS. (up)

With a market share of 16.8% or 18 Billion US$ Caterpillar sits indisputably in the first place spot. It is followed by Komatsu with a market share of 11.6%. Hitachi pushed Terex out of the Bronze medal spot and Liebherr advanced

two steps to the fourth place posi-tion. Volvo has the fifth place with a market share of 4.3%. The first Chinese manufacturer was found in 17th place last year. This year XCMG advanced to the 10th place. The only CH firm on the list is Am-man on spot #26.

Of 10 machines built for the in-dustry, 3 are from Europe, 3 from North America and 4 are from Asia. (up)

APS 15

At the small but fine TKD (Tech-nische Kontakt Dagen) exhibition of construction machines in Barne-veld, NL, the company introduced the APS 15 scraper trailer from AP Machinebouw. The trailer was paired with an AGCO MT865C Challenger tractor and ploughed through the testing grounds. A spe-cial feature at the TDK expositi-on is that almost all machines are available for visitors to try out.

The 22.7 ton tractor equipped with tracks had no problem filling the scraper trailer that can hold up to 15 cubic metres (heaped) of san-dy soil. The special feature on this trailer, measuring 3.5 metres in width and weighing in at 12.5 ton-nes, is the fact that the waste is not ejected at the rear, but dumped over the front of the unit. Two thirds of the total weight, the 39.5 tonnes of the trailer, is supported by the four 235-25 Michelin tires while the rest of the weight is supported by the rear of the Challenger tractor. (up)
