As a tribute to this truck this project shows some of the unlimited possibilities. It is a model of a KrAZ 255B 6x6 off-road truck which is used for extreme applications. Even though this specific truck was never produced as a civilian truck however after its retirement it has been used as such. Within a couple of minutes it can be changed into one of the four different editions which include: - Semi-truck with fifth wheel - Ballast tractor with ballast box - Trial Truck edition - Log Truck with stinger steered trailer So it is up to you what kind of job it does: just having fun as it being a Trial Truck, or will you give it a semi-trailer? Or will it be hauling logs? The truck features: solid axle suspension on all axles of which the rear axles use a tandem bogie suspension, PF powered driving on all axles 6x6 drive, reduced speed to increase power/torque, Servo powered steering, fully functional fifth wheel, modeled V8 engine, detailed cabin interior and two light units. Actually you could build this yourself. Building instructions and inventory/parts list are available. Early in the building process you will see what it is that you are building. You will be very excited from the moment you start the build of "Truck T14" KrAZ 255B 6x6 till you finish it with about 290 different parts totaling 1800 pieces. Scale: 1:17,5 Length: 477 mm (+ trailer 926 mm) Weight: 1,92kg (+ trailer 2,41kg) Parts: 1840 (+ trailer 2270) This KrAZ 255B 6x6 model is powered by a YaAZ-238A V8 4-stroke Diesel Engine which is visible with the hood opened. This power source has 8 cylinders in a V setup with a displacement of 14,87 liters. The initial YaMZ-238 delivered 215 hp with a torque of 785 at 1500 rpm. Since 1966 the YaAZ-238A engine was installed and delivered 240 hp with a torque of 883 at 1500 rpm. This detailed V8 engine is nice to build and to give it those realistic looks a total number of 80 parts is used. It is detailed with for example air filter, fan, fan belt, pulleys, hoses, by-pass oil filter and the exhaust system. Both L Motors, which are used to power the truck's drivetrain, are positioned laterally on each side of the chassis. The rotation of both L Motors is reduced using a single gear reduction one for each. The power produced by these motors individually is merged by the length differential. To increase off-road capabilities it has limited slip applied. One out going shaft is powering the front axle, but not without being geared down once more. The second out going shaft of the length differential is powering both rear axles. Both rear axles have there own gear reduction which is equal to that of the front axle. Again limited slip is applied, but to the rear axles only. The front axle has Rubber Belts installed instead of shock absorber. It's double rear axle setup is fitted with a tandem bogie suspension. The use of this setup allows easy axle and wheel travel. Both front and rear axles are fitted with "Technic Steering Wheel Hub with 2 Pin Holes". These hubs have proved to be a real improvement, less friction and the wheels do not bend under the weight of the model as it would without. Semi-truck with fifth wheel For a basic configuration a fifth wheel is mounted. Because of this a semi-trailer can be hooked up. Since this is a common application it makes the truck extremely versatile and depending on the used trailer it still suites any kind of terrain. At the rear end of the chassis has wedges installed to allow easy attaching of any semi-trailer. By adding a winch the versatility can even be increased. The battery box is simply sitting behind the cabin and the spare tire is mounted to the truck's roll bar. Ballast tractor with ballast box As used to haul extremely large and heavy loads this truck can be fitted with a ballast box. What it basically does is adding weight to the rear axles to improve traction. While fifth wheel mounted trucks have there semi-trailer to add weight to the rear axles it is now replaced with a ballast box. The truck's battery box acts as the actual weight. A spare tire is mounted that fits the truck as well as four spare tires that would fit for example a drawbar lowboy trailer. Trial Truck edition To be used as just an off-road truck to fool around with a trail truck body can be installed. To distribute the weight of the truck equally over all axles the battery box placed on top of the rear axles. Even though spare tires are not common for trail trucks two are installed to improve the looks of this truck. It is always impressive to see a truck with these large wheels having some spares. Mounted to the roll bar and easy to access when needed. Log Truck with stinger steered trailer Using this truck to transport logs requires to additions. The first one is a bolster mounted to the truck's chassis. It is sitting directly on top of both rear axles which enable good weight distribution. Second is the stinger steered trailer. Basically this trailer is a large tube with a tow ball at one end and a partial chassis with a bolster and two sets of wheels attached to it. The two sets of wheels are attached to solid axles which uses the same hubs as the truck does. Essentially the axle setup is equal to that of the truck without the drivetrain. Again it uses a tandem bogie suspension setup which allows easy axle and wheel travel. To hook it up to the truck it has a tow ball which connect to the truck's tow ball socket. The trailer's bolster is exactly the same of that of the truck and both are foldable. Finally the partial chassis with the axles and bolster attached is slidable. Allowing the full log combination to haul different lengths of logs.
Hello Everybody! My latest creation of which I am very keen! Loved to build it, including the design, color scheme and it's functions/features. Initially build for this amazing book "The Art of LEGO Scale Modeling" in which is fully "shiny". Yes, a lot of chrome parts are used to make it even more impressive. For a guy who lives in the Netherlands for whole of his live it took quite a while to get started with a "Euro" truck Well, here it is! Well, I am curious what it is that you think of this MOC, please share it... Would you be interested to build it yourself? Well that's possible. I have building instructions and inventory/parts list are available . Early in the building process you will see what it is that you are building. You will be very excited from the moment you start the build of "Truck T13" till you finish it with about 420 different parts totaling 2790 pieces. The truck features: solid axle suspension on all axles of which the rear axle uses tandem bogie suspension, PF powered driving with power transmitted independently to both rear axles, Ackerman geometry on steering axle, Servo powered steering, fully functional fifth wheel, fifth wheel slider, detailed engine bay, modeled Scania V8 engine, detailed cabin interior and 3 light units. Scale: 1:17,5 Length: 444 mm Weight: 2,21kg Parts: 2790 The Scania 3 series is the third generation truck model range introduced by Scania, which we all know is Swedish truck manufacturer. Obviously it is the successor of the 2 series and was introduced back in 1987. With the release of the 4 series in 1997 production of the 3 series stopped after being produced for roughly a decade. Given the fact it has a hood or bonnet, so it is not a COE (cab over engine) truck, it is referred to as a torpedo. For this the manufacturer gave it a prefix as well, a T. At that time the 3 series T came in a range of different engine sizes and horsepower. Starting with a 9.0 liter engine with 230 horsepower all the way up to a massive 14 liter V8 engine with 500 horsepower. Being available with either a 9, 11, or 14 liter engine truck models were denoted 93, 113, or 143. To indicate the rating of the frame and suspension stiffness a letter suffix is used. Rated with an M indicates this model has a „medium” frame and suspension setup. Other suffices used by Scania are H for „heavy” and E for „extra-heavy”.
