2 Translation of page 3 Editorial Confidence I hope that your New Year started smoothly. I was able to pop the champagne corks this New Year with a great deal more confidence than before. For this, I owe many thanks to you, our readers. Numerous subscribers stuck with us during our difficult time last year and many of you even rounded up your subscription amounts very generously. Unfortunately, it is not possible for me to thank you all individually; therefore, I send you all a heartfelt thank you at this time. In addition, our advertisers, dealers and sponsors have been extremely loyal and supportive during the same time; a very big thank you goes out to you too. For the first time, see page 40, there are two articles about our partners in the construction trade. They are providing much needed financial support for this year. We will feature articles of interest to the construction modeller and collector about them in every issue this year. Eberhard Bau AG needs no introduction, especially to all Caterpillar fans out there. However, Bärlocher Steinbruch AG, a quarry operation, will be a welcome discovery for many fans. We are sure that the articles will enrich our pages and enthral our readers. I am looking forward to further co-operation with them. The arrival of both brand new Caterpillar 992C models just before our deadline meant a quick re-shuffling of the content. It is not every day that pre-production models land on my desk. It was not an easy decision to take the completed article about the Komatsu D475A-5 out of the magazine. However, nothing is lost. It is available in pdf form as a free download on our public Facebook page. (See left hand column for all contact information). Of course, the appropriate English translation is provided. Finally, I would like to inform you that we have moved. BAG- GERMODELLE will now be produced at our new address: Güterstrasse 6, in Berne, Switzerland. Have fun reading the newest edition of BAGGERMODELLE. Daniel Wietlisbach BAGGERMODELLE online:

GMTS 1:50 To augment the Golden Oldies series, this new ŐAF Tornado 230 6x4, equipped with a quarried stone bin, has been released. In the 60s and 70s, the Tornado was among the biggest sellers of this kind of truck in Austria, and was also seen here in Switzerland. The resin model has been refined by the addition of a myriad of small detail parts; the most noticeable one is the fully chromed dumping cylinder. The dump truck comes, as usual, in four different and limited colour schemes for the collector. 4

5 Translation of pages Bruno Bieri collects his own creations The Crusher Master by Daniel Wietlisbach The story of how Bruno Bieri s passion for collecting began is similar to many others. Despite this, his collection is very special indeed. He collects only rock-crushing machines and the related transport trailers and excavators necessary to feed the crushers. All these are tastefully arranged in his display cabinets. Over time, his small, but very fine collection grew. Bruno Bieri grew up in a rural area, right beside a construction firm s yard. Some of his school friends fathers worked on construction sites during the booming 60s. Thus, it was possible for the boys to be aware when something special was happening on the sites. Afterwards, at home, the scenes observed where re-created, using the few construction machine models available at the time, for example, the Dinky Toys Euclid dumper truck or the Coles 20-ton crane, toys that almost every boy played with. Re-discovered Completely unexpectedly, when Bruno was 27, he stood before two models that immediately captured his imagination. At the time, he was working as a factory layout designer for Moos schen Eisenwerke near Lucerne. When planning a new scrap iron transfer yard, the decision was made to Construction machines were always of interest to Bruno Bieri. Despite this fact, he considers himself a late entrant into the hobby of collecting construction machines. Interestingly, he collects only his own scratch built rock-crushing machines acquire two Liebherr A 921s. The specially designed machines, built in 1974, equipped with scrap tongs and a higher than normal mounted operator s cabin, were custom made and not run of the mill machines. When the machines were delivered, two models of the A 921 from Gescha in 1:50 (#2821) were given as gifts. One had a digging scoop and the other one a grappler. Bruno Bieri was allowed to keep both of the models and this was the beginning of his collection. In the nearby town, the model railroad shop reserved a corner for construction machine models, a practice common at the time. Our freshly minted collector visited there often and very soon, a six axled Liebherr LT 1100 from Gescha (2072.1) joined his excavator models. He became a regular visitor to the Caterpillar and Liebherr dealerships and so his collection grew with the models that were available for purchase at these locations. He would have liked to add machines from different makers like NZG and Conrad, but at the time, it required a lot of writing and patience just to get a catalogue or leaflets. When the information finally reached the collector, often the listed models were already sold out. That is why the excavator models from O&K and Fuchs remained single models in his collection. Sold everything It was the beginning of the 80s when Bruno Bieri discovered an article in a paper describing the first crawler rock crusher, a custom designed machine for the firm of Aggregat. It was built for them by Maschinenbau und Hydraulkfrima Emil Gisler in Seedorf, Switzerland. Bruno Bieri was fascinated and decided to build such a machine in 1:50 scale. To obtain the blue prints for the RBA004, he contacted the company Aggregat. Unfortunately, they had only a few detail plans and mainly sketches! These very few 5

6 Translation of pages first rock crusher crawlers were welded together using different components without any plans, according to the customer s wishes. The very first crawler-mounted rock crusher was mounted on a retired excavator platform. Not discouraged, Bruno Bieri visited all of the rock crushers in situ, to take measurements and pictures from all angles. Using brass profile shapes and ACC glue, the first crawler crusher model took shape built on a discarded lower carriage from a RH9. The fascination with this special segment of the construction trade, and successful construction of the model changed his collection direction. From then on, he focussed his collection efforts on models that could transport these machines and machines used to feed the crushers. Finally, in 1998, he sold most of his models, about 300, at several swap meets. Only a few Cat models and a few more of the Liebherr models remained. Scratch built models refined Demand for the specialized rock crusher on crawler base increased the business of Aggregat and increased the size of Bruno Bieri s collection. The very lightweight, mobile crushers were easily transported and were used to recycle material on building sites for high alpine meadow, agriculture and forestry roads. The first crusher crawler combinations were designated RBA001 to RBA012. After the twelve units, the firm of Aggregat switched production and concentrated on large construction projects and large conveyor belt assemblies. They are still active in this field today under the name of Agir. The Collector Bruno Bieri, 64, first apprenticed as a building draftsman and then worked for 15 years for a large steel manufacturer as a factory layout planner. There he was also involved in the trade of machine drafter. For a further 15 years, he worked for a middle-sized construction firm as a purchasing agent. Finally, he worked for a security firm before retiring early at age 62. He is married, has two sons and lives in Emmen, Switzerland. His early collection was of no interest to his family but now they are interested in preserving the unique crusher plant collection. Bruno Bieri s series of the 12 crushers was not completed until For every model, he had to visit the crusher at work and take exact measurements. As is common with modellers, each model he constructed was of a better quality than the last. In the beginning the selection and quality of brass profile shapes was rather limited. The offerings have improved greatly over the last few years and it is possible to have custom shapes made to order at affordable prices. (See Rather than using out of service excavator undercarriages from the scrap box as in the past, Bruno Bieri had the firm of Unicata make him customized undercarriages. The very distinct and visible fly roads and wheels were made in the apprentice metal shop of his employer. He only has a metal saw, a drill press and grinder in his hobby room. Gipo-plants After Aggregat declined to build further crushers, Emil Gisler founded the Gipo Company in the early eighties and started to produce a successful line of crushers under his name. When Bruno Bieri attended the 2010 Bauma, he dropped in at the Gipo stand and struck up a conversation with the CEO Kari Gasser. From this chance encounter developed a fruitful relationship. Bruno Bieri had retired early and was able and very willing to use his spare time to build a model of the largest crushing plant from Gipo for their show room. The Gipo Combi RC 170 FDR is, as the name suggests a combined crushing and sifting plant. It weighs 135 tonnes when in use and is currently working for a reclamation firm in Manchester, England. With all plans at his disposal and the full support of the manufacturer, Bruno Bieri s creative urges went into overdrive. During the last two years, he hand built the most detailed models ever of the three Gipo plants; the fourth one is already in the planning stages. And what about his collection? It has grown with the addition of Nooteboom models for the transport of the crushers; these go very well with the green or red machines. The lowboy truck and trailer units were financed by the sale of further older models through a dealer. 6

7 Translation of pages Caterpillar 992C from CCM in 1:48 scale Hitting the high C It was in 1977 when Caterpillar revolutionized the bulldozer world with the Cat D10. Soon after, the C-version appeared. At that time, it was the world s largest wheeled loader by Daniel Wietlisbach The main difference between the 992B and the 992 was the new cabin with the distinctive rollover protection bar. However, the 992C was completely newly developed. The machine has an operating weight of 85t with a shovel capacity of 17t and is capable of filling the bin of a Cat 777 dumper in only five loading sequences. The power plant used for the 992C is the Cat 3412 V12 diesel engine that produces a remarkable 690 hp. For use in quarry situations and on rocky ground, the 992B was offered with Beadless tires. These beadless tires have a wire cage embedded in the rubber outer housing, and have steel plates attached to the outside: this improves traction and gives the tires longer life. When specialized heavy-duty quarry tires for large earth moving machines were introduced to the marketing the 80s, beadless tires were no longer produced. The model from CCM At a glance + Choice of prototype + Detailing + Beadless -tires Lifting cylinder without an arresting position It will be 35 years after the introduction of the original when two versions of the Cat 992C from CCM hit dealers shelves in March of CCM was kind enough to provide us with a pre-production model for a closer look. The road loader model is constructed mostly from metal; this gives it a substantial weight. When checking the measurements against the prototype a few, small differences of only millimetres were found; these can be ignored. The tires are very convincingly modelled. They fit snugly and sport the Goodyear logo. The rear axle oscillates as on the prototype. The drive is modeled completely even on the underside. A hint to modellers is always to have a look underneath. The maker has taken pains to model the engine as well as the power shift housing in detail. This goes also for the V12 engine that can be seen through the finely etched air intake openings on the sides. It is very tempting to remove them to get a better look at the engine. The radiator grill is made from a fine etching, but the upper engine cooling screens are cast on and have been drilled open. The latter are a bit coarser than the etching and have fewer holes. This solution was probably necessary for stabilization reasons. The articulation mechanism with the two hydraulic cylinders and all of the hydraulic lines as well as the gear shaft to the front part of the unit are completely modelled. The cabin, with its characteristic look, is 7

8 Translation of pages excellently reproduced. The great look is further enhanced with snug fitting windows including gaskets. When the operating door opens, it allows an unobstructed look on the detailed, multi-colour interior. Unfortunately, the very finely cast rear view mirrors are not real but painted in a silver color. The same goes for the head, rear and brake lights. All handgrips, railings, ladders and steps are very fine metal castings. The fire extinguishers and exhaust pipes contribute to the positive overall look of the model. Careful when using the lifting mechanism With the shovel in the lifted position, the model gives a superb impression. The lifting mechanism must be handled carefully as it has no arresting position. The impression of the lifting mechanism is in no way compromised by any misplaced oversized bolts. The properly dimensioned lifting cylinders and the complete hydraulic lines harness are convincingly modeled. The rock shovel with etched overloading protection screen is very convincing. Perhaps it would have been better to give this model a smaller shovel bucket. This attachment works best with the beadless tire version. Another difference between the two models is the fenders on the front unit. The tires with their two-segment, tiny steel plates, including the screws are exquisite. The faultless paint job is the legendary, early Caterpillar yellow and the lettering, including the Pacman, logo is crisp.

9 Translation of pages Komatsu D475A from First Gear in 1:50 scale Power Dozer First Gear has created a mighty model with its new dozer. The manufacturer upholds its usual quality in this new scale of model regulate the tension on the tracks were bent the wrong way. After carefully removing the tracks, extending the springs with a screwdriver blade and replacing the tracks, the dozer ran like a charm, even on flat and slippery surfaces. The middle six running wheels oscillate and turn as on the original. The two outer wheels are only simulated; however, the two upper support wheels turn. The two sets of running gear are mounted on to the main frame, so that they oscillate correctly when the model moves over rough surfaces. The huge engine hood, the driver platform and the tank area are engraved metal or plastic castings. There are many detail parts on top of the castings: exhausts, air filters, spotlights, steps and many handrails invite closer inspection. A massive rollover bar equipped with six headlights and six window wipers, protects the operator s seating space. The black wipers fit exactly as do the window gaskets and separation frames. The two-colour interior of the operator s platform is correct. by Daniel Wietlisbach It was eight years ago when First Gear set new standards in the construction of tracked vehicles with their model of the D375A. Subsequently, many manufacturers have followed the same standard. Accordingly, there were high expectations of this new dozer. Checking against prototype measurements is made easier by the fact that there are detailed drawings of the model from two perspectives on the backside of the package showing all-important measurements. The proportions of the machine are exact to prototype, excluding the small difference of 3mm in overall height, when measured to the top of the rollover bar. The frames for the running gear are very nicely detailed and there are no assembly screws visible to mar the picture. With this detail, First Gear returns to the proven standard that was missing in the last two models released in 1:25 scale. The easy-running metal tracks are constructed prototypically from 41 one-piece segments. The ground level plates models are 910 mm wide, a very welcome detail on a dozer model of this size. Unfortunately, on our test model, all four springs that At a glance + Detailing + Scale correctness + Choice of optional attachements Ripping tooth is not adjustable Equipment The four cylinders used to operate the blade are very well detailed. The freestanding hydraulic lines to the lifting cylinders are complete; the modelling of the connectors is exceptional. The tilt cylinders are well protected and hidden from view as on the prototype. To match the massive tracks, the machine has been given the optional, reinforced Double tilt-u-blade that is a half-meter wider than the standard blade attachment. The protection fence on the top of the blade is perforated as on the original. The casting for the ripping tooth at the rear end of the machine is very convincing. The massive beam and the suspension are nicely engraved and are very detailed. The four hydraulic cylinders are present and the twelve hydraulic lines are correctly freestanding and very flexible. Unfortunately, the ripper is fixed at the uppermost position from which it can never encounter the soil below. The paint job is faultless and the lettering crisp. In this limited edition of 360 pieces, the D475A-5 is available in the blue and white color scheme of the Roy Ferguson outfit.

10 Translation of pages Liebherr rapid deployment cranes part 2 Time travel with models How did construction cranes change over time? In the second and last part of this article, the trolley plays the leading role by Carsten Bengs The disadvantage of needle beam cranes was obvious: they needed tracks to operate and were more difficult to transport because they had substantially longer pieces than their replacements. The trolley comes This was the reason why cranes with trolley mechanisms enjoyed an increasing popularity. The principle was simple enough: the destination of the load was controlled by moving the trolley forward on the arm. Liebherr introduced the first trolley-equipped, rapid deployment crane at the beginning of the 60s. In addition, as a new feature, the tower no longer tilted forwards during the breakdown of the assembly but backwards thus saving a lot of space. The 21K appeared at the beginning of the 80s. This model is still seen occasionally on today s construction sites. The typical silhouette with its two A frame brackets is unmistakable. The greatest similarity between these cranes is in the way the jib arms are erected. After the main tower of the crane has been assembled, it is telescoped out and the jib folds out from the assembly using a wire pull. The counter weights for the crane are concrete blocks with a total weight of 12t. The filling of the counterweight container with sand at the construction site was outdated. As a quick deployment crane, the 21K could be transported with its ballast blocks and so reached a total loading weight of 20t. When the jib arm was fully extended to 23 m, it was still capable of lifting a maximum load of 800 kg; otherwise, the maximum load was 1750 kg. Conrad used this 21K crane as a prototype for its model in the 80s. Regrettably, this beautiful model remains the only lattice tower crane model in 1:50 scale. Naturally, it is one of the most sought after crane models. For its time it was a nicely detailed model that faithfully copied the very compact construction of the crane. The crane sits on two axle assemblies attached to the unit using two little bolts. The erecting process follows the prototype closely. After successfully extending the four support arms using the four little screws to level, the front axle is removed and the tower assembly is fixed in place, secured with a small bolt tightened with the small key that is included with the crane model. All steel wire ropes run freely on the very free-running dolly wheels. The winch erects the un-locked tower assembly that telescopes out to the full length and then the jib unfolds by itself into a fully horizontal position. The whole unit is secured by the insertion of a locking bolt, and then the rear transporting axle assembly has to be removed. The only variation from the prototype is the omission of the ballast gallows type crane. The crane engineers from Bieberach, Germany came up with another sales hit about 10 years later with the new types 28K and 32K, made using the solid panel construction mode for the tower. This meant that the whole tower structure was strengthened and the tower unit was flatter for ease of transportation. Both cranes were able to erect themselves 10

11 Translation of pages on the construction site without any help from other cranes. Special mounting gears and winch allowed the crane assembly to be vertical after delivery to the site. This mounting arrangement also had a second function; it lifted the concrete counterweight sections from the truck right to the ballast tray. At first, Conrad released the 28K, and then later, this model was released as the 32K version, easily recognizable by the black interior color of the tower and the white operator s cabin. When being transported, both of the axle assemblies are connected in a prototypical arrangement to the upper or lower carriage, depending on the model. The crane can be moved sideways using the turning mechanism and so can be located on the site with pinpoint accuracy. The unfolding of the A-frame is simulated successfully by using the small metal hooks. After erecting the tower of the crane, the ballast sections are added; unfortunately, all ballast sections are moulded together as one piece. The single plates are only simulated and the ballast gallows crane is only for show. The very unreal looking hook can be replaced with something better from the scrap box. This allows the modeller to simulate the removal of the rear axle assembly. Contrary to the prototype, jib arm segments of models from the 80s and 90s are open at the bottom end. Fortunately, this is no longer the case with the newer models. The rear tension arm of the jib is held in tension with a flexible cable; this allows the model to display the jib in different luffing heights. The uppermost jib support is especially interesting. On the 21K, cables were used as support, whereas on the new series of cranes, Liebherr has used a telescoping crossbar. This feature, which is standard on today s cranes, simplifies the assembly process immensely. Conrad has incorporated this feature very nicely in the model. TT series is coming At the beginning of 2000, Liebherr launched the TT series. Originally, this series of cranes had several types. All the cranes in this series had telescoping jibs and solid panel towers. This idea was used first by the Belgian crane maker, Acromet, in their T series. Today the Liebherr crane of the series is the very successful 32TT with a maximum 24m height at the hook. The great advantage of this type of crane is that it is very flexible and can be adapted to all requirements on a site, and because of the telescoping jib, does not take up excess room when transported. At its greatest extension, the crane jib reaches 30m and is still capable of lifting 1.1t. The maximum load capacity is 4t. With these parameters, the 32TT is destined for employment at even the tightest construction sites. At the 2004 Toy fair, NZG featured the new and very detailed model of the 32TT. It was the very first tower crane released in the history of the Nuremberg toy maker. In the mean time, prototypical detailing had reached a high level of accuracy. This was especially so on the 32TT, and so a comparison with the 28K and 32K is not fair. However, the most noticeable difference on the model is the fine scale thickness cables. They hold the jib arm in place and, using a small winch on the outrigger base, help to extend the jib to its full length by telescoping the segments. In addition, the outrigger arm segments are not open at the bottom and the trolley has integrated small spring elements. These help the trolley to press tightly against the jib. That allows the trolley to travel the full length of the jib and sit evenly tight against it, even on the slightly narrower front of the arm. The securing of the separate tower segments is also prototypically correct. Here the internal and external parts of the crane tower are secured with a small quick connection clamp that is released automatically when the crane reaches the 90 position. Then the assembly winch telescopes the tower out while maintaining the jib arm in a vertical position. Alternatively, the model can be displayed telescoped in close; this shows the high flexibility when in use. Earlier the ballasting was only simulated and in one piece. Now, on this model the ballast is comprised of several sections. The icing on the cake would have been if the ballast, 22t on the prototype, were modeled in single sections. However, the little steps and hooks for the lifting are nicely done. The whole assembly is supported on solid struts that have threaded support columns giving the model a sound footing. The axle assemblies can remain attached to the model in this mode; however, it is best to squish the bolts flat slightly using a pair of pliers. This prevents them from slipping out of their holding rests. With this model the end of our time travel is in sight, it only remains to be hoped that the future will bring further crane models and there are plenty of prototypes to choose from. 11

12 Translation of page 25 Remo s old Iron Here you can challen- Recognized? ge your know-how. Recognize the machine and win a model! by Remo Stoll T his cable-operated excavator from the 70s is retired but not scrapped. Today it is on display at a small museum sitting forlorn by itself. There is also a dozer and a continuous bucket dredger on display. The excavator can be found in Germany, to be precise in the Eifel region, were it was previously used to mine pumice stone. Then send us the exact manufacturer s name and the model number on a post card by mail. We also accept submissions (contact information is on page 42). The contest ends 15th February Should there be more correct answers than prizes a draw will be held. The winners will receive the Goldhofer lowboy trailer combination with MAN TGX XXL in the Bohnet colors from Conrad, the Liebherr A 924 Litronic in the colors of Wurzel-Bau by NZG and the Ginaf 10x4 dumper from WSI. Solution from BAGGERMODELLE The difficulty was in the detail. The missing steel plate underneath the ballast box pointed clearly to a Hamm GRW 10. A draw decided the winners from among the many correct entries. The winners are Walter Jenni from Emmen (Switzerland) who won the Volvo EW160C mobile excavator from NZG, Dominik Whörl from Kulmain (Germany) who won the Mercedes Actros 8x6 heavy-duty tractor truck in the CharterWay from WSI and Cornelia Wegmüller from Biberist (Switzerland) who won the Cat CT660 four axled dump truck from Norscot. We congratulate all the winners! 12

13 Translation of pages Sennebogen 690 HD from ROS in 1:50 scale Green Henry by Daniel Wietlisbach The model of the 60t machine arrives fully assembled for the collector and therefore, it cannot be built differently and displayed in transport mode. To balance this critique, it must be said that, due to a lack of time or space, many lattice tower crane models are never built. The model passes the test with flying colors as far as prototypical measurements are concerned. The only deviance is in the range that drive sets can be telescoped which is short by 2.5 mm. The lower carriage is sturdy and very well done. The driving wheels and the sprung guide wheels are modeled as such and are fully functional. The 12 guide and support wheels are cast on and do not function. The simple running wheel protection skirt is not modelled. The metal tracks are constructed correctly from three-piece segments, but because of the heavy springs used, are not easy to turn. The tracks do not sag when fully extended, which is a commendable detail. The steps are delicate and are correct in location and number. Several warning and instructive labels complete the under carriage. Upper carriage The upper carriage is made of cast metal and the appropriate air The announcement from ROS that they would release a model of the Sennebogen 690 HD caused quite a stir. Many collectors waited in suspense for the first cable-operated excavator from ROS intakes, door cracks and knobs are all engraved and visible. The counterweights are cast in one piece and are correctly connected with a chain to the self-erecting unit. The plastic cast operator s cabin features perfectly fitting windows, simulated window gaskets painted black and a complete interior. The required number of window wipers, rear view mirrors, handgrips, rails and ladders is correct. Unfortunately, all plastic castings are slightly over scale. The two clips that hold the keys for the operation of the three winches are located behind the exactly fitting, removable cover of the right upper carriage At a glance + Choice of prototype + Scale conformity + Brass pulley wheels Suspending is too long The drums of the winches cannot be braked side. Unfortunately, there is no satisfactory locking mechanism. The danger exists that the grappler will descend precipitously to the floor. We found a simple solution to this problem on the NZG Model of the LTM Cables of the Y suspension rest in the upper dolly wheels kept in place by small pieces of foam. I took some small foam pieces and inserted them, using a toothpick, between winch drum and support. A small drop of ACC kept them in place. This little intervention is invisible and gives the winch drums enough resistance to prevent the grappler from crashing to the floor. Equipment The foot piece of the jib is made as a separate piece, but the jib pieces and the headpiece are made from a single casting. The excavator thus reaches the original length of 20 m. The suspension cables are made from one single, continuous plastic cable. Since the two lower 13

14 Translation of pages pieces are too long, it is impossible to position the jib in the fully upright position; trying this manoeuvre brings the A-frame into transportation position. Because the material for the pulleys used throughout is brass, all cables move without any binding or other problems. The Diaphragm wall grab is a K 810 HD from the Stein Company. It has a maximal mouth opening of 3.4 m, weighs t, and is constructed from combination of metal and plastic castings. Combined with the brass dolly wheels it works extremely well. An allmetal construction would cause this model, and many others, to tip over because of increased weight. The guiding frames are made from plastic, but the jaws of the shovel are made from metal, as is the opening mechanism. The bolts used to hold the assembly together would almost disappear with a drop of paint. The grab tends to twist but if both cables are under the same traction, it can be handled optimally. Special civic engineering machines are for specialists; this goes for their models as well! The paint job and lettering are excellent. It is hoped that further variants of this very nice cable operated excavator will appear in due course. 14

15 Translation of pages Hamm HW 90B from WSI in 1:50 scale Evergreen in orange Even during the current reign of tandem road rollers, demand for the classical three wheeled road roller remains strong by Daniel Wietlisbach At the end of 2011, the firm of Hamm was able to look back on 100 years of road roller construction. This jubilee was also a reason for construction model collectors to celebrate as more models of road rollers than ever before have been released. Special praise should go to Tirschenreuther for the last model. The HW 90B, a constant seller for over thirty years, does not represent the latest technological advances. It is especially popular in Great Britain and the Netherlands. The purely static roller, without any vibrator, is often seen at work with a tandem roller. The machine is available in two weight classes, and kg. They can be ballasted up to a maximum of 12 and 14 tons. For the hydrostatic drive, a76.8hp Deutz four cylinder is used which ensures that it conforms to the EU exhaust control tier IIIA. With its striking design, it hearkens back to the beginning of the 80s. HW 90B by WSI The newest release from the Dutch maker replicates the characteristic look of the prototype perfectly and is true to scale in all dimensions. At first glance, the plain exterior hides many of the details that wait to be discovered. Whilst the rear drum wheels are finely engraved castings, the front drum wheel with seamlessly modeled bandages, is plain, just as on the original. The front drum wheel suspension is modeled correctly right down to the steering hydraulic cylinder. The ballast and motor housing has all the original vents and service openings, checker-plated steps, handgrips and finely etched, air intake screen. However, unlike on its predecessor, the HD+110, none of the lids open. The protective grids on the headlights are very delicate. The back up lights are made from separate pieces. Three steps reach the operator s cabin that has an opening door. There is a driver s seat on each side of the middle console. Interior sun visors provide shade and rear view mirrors increase visibility. All windows fit snugly, flush with the outside surface. The raised window gaskets are matt black. Two window wipers on the divided front window are separate castings. The remarkably slim exhaust pipe is mounted in the middle, in front of the cabin. Cargo The HW 90B is an ideal candidate for transportation especially when combined with the HD+ 110 tandem roller from WSI. It is an excellent fit for the ASD four-axled lowboy from Nooteboom, also newly released. The lowboy trailer, loading capacity of 40t, with an empty weight of only 8t, is a specially developed unit for the road construction business. An ordinary (dumper) truck can pull it. For now, the new WSI model comes only in the red of the Dutch maker and is available only from them. The truck chosen to pull the trailer is a Ginaf X4345 TSV 8x4 dump truck. The ASD is an excellent model, superbly detailed and very functional. For example, the outside extension boards that are prototypically hinged can be tilted upwards and secured with functioning brackets. Two part hydraulic ramps, which are secured during transport using real scale chains, are used during loading and unloading the unit. The whiffletree is kept in place with a spring as per the prototype; however, it is a bit high. A small matter that is easily fixed. The Hamm HW 90B and the tractor-trailer set have an excellent paint job with crisp and very legible writing that contributes to the overall prototypical look. 15

16 Translation of pages 30 Palfinger PK from Conrad in 1: 50 scale Big things can come in small packages by Carsten Bengs The truck platform chosen for the mounting of the crane was a MAN TGS in the attractive color scheme of Wiesbauer. Both front axles and one of the rear ones are fully steerable thus, the model has a tight turning radius. On top of that, the pre-ultimate rear axle oscillates. The model truck and crane have six support braces: four on the sides, and two on the front. They are made of plastic, except the last segment of the rear support, which is made from metal. The front bracing hydraulic cylinders on this unit fold upwards during driving as they do on the smaller sibling. The truck-mounted loading crane is very impressive. It extends to 48 cm (24 m on the prototype) and so competes well with smaller mobil crane units. In total, there are nine After releasing the PK53002 earlier on, Conrad now brings the much larger PK truckloading crane. Like the earlier version, it has convincing detailing and functionality extendable telescoping segments on the crane arm. All are plastic; die-casting would have made the crane too heavy. All eight telescoping segments have a very nice, simulated hydraulic cylinder, cast in metal and a blackened metal tube. The second to last telescoping piece extends mechanically and is interlocked. The crane has two optional hooks. On the model under discussion, the seventh telescoping segment is equipped with a winch for lifting operations. Two small guide dollies on the mast ensure that the cable stays safely in place, especially when the truck is moving. Impressively, Conrad has given this model real metal pulley wheels. Massive hydraulic cylinders ensure the stabilization of the crane arm without sagging. These cylinders are definitely more difficult to move than those on its predecessor are. The hydraulic fluids tank, cooling unit and turning engines on the crane are well modeled. It is a perfect companion to the LTR Because the ballast tray is easily removed, it can also be used as a tractor unit for a ballast trailer. Overall, this is a very fine, highly detailed and fully functional model in the proven Conrad quality. 16

17 Translation of page 31 Eye Candy Sennebogen S1020 by Albert Schmid It was towards the end of the 70s when Sennebogen started marketing the 1020 model. This universally useful excavator had a two-part grabbing or dragging shovel. In its crane configuration, its foremost task was the lifting of loads. It was available as a mobile or tracked excavator with total weights of 19t and 23t, respectively. The power plant for the series, the air-cooled KHD F6L 912 diesel engine by Deutz, produced 105 hp. When using a short, 8.5m mast extended to 3 m, it was possible to lift loads up to 20t. There were 10 lattice mast sizes available as options. With an additional extension jib, a top wheel height of 30m could be achieved. The main boom could be folded down to transportation mode using a hydraulic folding mechanism. Since 1969, hydraulic operated cranes and cable-operated excavators have been the mainstay of Sennebogen, an excavator manufacturer located in Straubingen, Germany Upon prodding from some users who wanted even more mobility, Sennebogen agreed to mount a few of the S1020 Lattice cranes on truck chassis. These mounted units were custom made for specific users and therefore were outside the regular production units. At the beginning of the 80s, Conrad created the S1020-crane model 2810 in 1:50 scale, on a mobile chassis with four-fold support struts and a foldable 11.5 m lattice mast. Around 1987, the model, 4110/0 appeared in the Conrad Catalogue with the description MAN-Senne- bogen-lattice mast. The information is from Conrad itself; no other information could be obtained. Therefore, there is no information on who commissioned the model or how many were produced. One guesses that there were not a great number of these models made. By the way, from today s perspective, the Sennebogen S1020 crane mounted on a truck chassis is the forerunner of today s truck mounted cranes. 17

18 Translation of page 32 New books Schwertransporte Bildarchiv 3 By Thorge Clever. Published by Verlag Podszun, 144 pages, 290 pictures, 28 x 21 cm, hard cover ISBN Whenever heavy-duty transports hit the road with their heavy loads, Thorge Clever was there to document them. In this newest volume, his third, the author shows off some most interesting transport situations. For example, the transport of a 320t transformer from Lake Geneva to Basel was a weeklong undertaking by the firm of Fridrici. This well-known entity needs no further explanation for any heavy-duty transport fan. Problems occasionally facing these transports are especially exciting for example, when the heavy-duty tractor units are stuck in the gravel and can no longer move forward. This happened when the Pieper company tried to move an 11m long boiler. The final solution was to use a LTM 1400 from Thömen to pull the unit out of the predicament; the LTM 1400 was intended for the unloading. (dw) Pieper Schwertransporte By Thorge Clever. Published by Verlag Podszun, 144 pages, about 290 pictures, 24 x 17 cm, soft cover ISBN If you want to find out more about the firm of Pieper, their history, fleet and transports, then purchase this book. The Dortmund firm was founded in With the need to transport ever-heavier loads, the firm grew and was a pioneer in the heavy-duty haulage business until the mid-1950s. Today the firm is one of the giants in the trade. After a short company history, Thorge Clever concentrates on the most interesting transports in the 1980s and 1990s. The book contains a selection of pictures from the author s archive of over 1000 pictures. (dw) Jahrbuch Schwertransporte & Autokrane 2012 Several Authors. Published by Verlag Podszun, 144 pages about 280 pictures, 24 x 17 cm, soft cover ISBN Since 2005, the release of this very handy annual issue for lovers of heavy-duty transport and mobile cranes has been a very welcome event. For 2012, well-known authors offer many interesting and entertaining articles, all under the heading of heavy-duty transport. For example, the book contains a write-up about the largest side girder deck trailer in the world. Constructed by Scheuerle especially for the transportation of transformers, it has a legendary carrying capacity of 620t. Cranes made by Krupp are featured in two articles. The first covers extra wide, four axled cross-country cranes used in above ground mining for lignite, and the second details the cranes used for modular home construction. (dw) Walking with Giants By Steven Vale. Published by Old Pond Publishing, 318 pages, English language, hard cover ISBN Steven Vale is well known for his DVD series, Massive Earth Movers. Walking with Giants is his first book. It concentrates on the largest construction machines in Europe. During a trip from Spain to Norway, he chronicles the gigantic machines, employed in surface mining and quarry operations transporting waste and raw materials. Komatsu Pc3000, Hitachi EX3600, Komatsu WA1200, Hitachi EX5500, Liebherr R995, O&K RH200, Cat 994F, LeT L1400, P&H 4100C, Komatsu PC5500 and Cat 795F AC are only a few of the huge construction machines described in detail and shown in many pictures. There is a short introduction to the mining or quarry sites at the beginning of each chapter. (up) 18

19 Translation of page 33 Tinplate Cable shovel from Joustra by Robert Bretscher This impressive, brightly colored excavator with front scoop comes from the French workshops of Joustra. The factory in Strasbourg was founded in During its existence, the maker specialized in manufacturing all kinds of mechanical toys. These appeared as technically refined, moveable animal figures, cars, trucks, tanks and fire engines. A special feature on this construction machine model is the changeover operating mechanism. A lever located on the left side of the housing activates this mechanism. The arm of the excavator is operated either by the built-in heavyduty wind up clockwork mechanism or with the use of the hand crank that is included with the toy. (The use of the crank eliminates constant re-winding of the mechanism when used for an extended period). Leverage is achieved The upper carriage of this excavator from the French maker, Joustra, has a strong resemblance to a machine from Weserhütte using an eccentric wheel located in the interior of the upper carriage housing allowing for the automatic lifting and lowering of the shovel with only one crank or motor movement. When the shovel reaches its zenith it is emptied by a release cable operated from the rear of the machine. The same work/play movement is repeated until the mountain of sand in the sand box has been moved. This technique is commonly used in the toy industry to simulate loading/dumping work plays. German, English and Far East makers have used the same up and down mechanism for many of their products. The orange and blue excavator is convincing with its well-proportioned looks. It is probable that an excavator from Weserhütte was used a prototype when Joustra designed the model. The solid tin plate with different air intake openings, partly open, the modeling of the windows, the coloring and the mechanical ingenuity show off the Joustra model very nicely. The model (at first, only as a hand crank unit) was sold initially in 1955 and remained in sale catalogues until By the way, the model still functions without any problems, even after 51 years! 19
