[MOC] M.G. Bryan "PERCHERON" - TATRA T815-7 10x10
Paliason posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi guys, I want to introduce you my latest model. It is a technological equipment intended for shale gas extraction: PERCHERON This unique solution, called ONE-ENGINE-TRUCK, is the result of the American-Czech cooperation of the following companies: * M.G.BRYAN Equipment (USA) - Percheron superstructure * TATRA TRUCKS (CZ) - chassis * GARDNER DENVER (USA) - pump * TALOSA (CZ) - auxiliary gearbox The basis of the PERCHERON system is a TATRA T815-7 10×10 truck and a GD-2500 Quintiplex Well pump from the American company Gardner Denver. The 2500-horsepower pump blows a mixture of water, sand and chemicals into the well. Behind the Tatra cabin is a 12-cylinder diesel engine, model 1163 from the German company MTU. It is used to drive the pump and the vehicle. Engine power is 5954 hp. However, this power only serves to drive the pump. Only about 700 horses are intended to drive the Tatra with some cylinders on the engine switched off. The Czech company TALOSA designed a special additional gearbox for the transmission of torque for the drive of the mining equipment and also for the drive of the vehicle. Shale gas extraction: Shale gas is found in shale formations hidden hundreds of meters or units of miles underground. Due to the low permeability of the shale, the gas bearing cannot be pulled out in one borehole, as is the case with conventional gas pocket bearings. Here, a mining technology called hydraulic fracturing /fracking/ is used. The drilling rig first drills a vertical well. A horizontal borehole is then drilled through the shale gas deposit. The shale gas layer is then broken with small charges. Subsequently, a special device starts pumping a mixture of water, sand and chemicals into the well. The water expands and branches the cracks in the slate and the sand prevents the cracks from closing. Finally, a device for extracting the released gas enters. Schematically represented well in comparison with conventional mining: Good video with animation of how the mining process works: https://www.youtube.com/watch?v=VY34PQUiwOQ&feature=emb_logo Lego model features: - chassis 10x10: central axle, swivel axles, 9 differentials, wheel displacement on one side relative to the wheels on the other side - turning eight wheels: first, second, fourth and fifth axle / second and fourth at a smaller angle / 1x PF-L Engine + 4x LA - opening the door, opening the cover on the central control panel - piston movement of a 12-cylinder engine - PF-Led lighting: a total of 8 pairs (16 LEDs), with only the front and rear being permanently installed in the vehicle. LEDs in the light bar on the roof and on the lighting on the superstructure were mounted only temporarily to take pictures in the dark. Dimensions: - length: 100 cm - height: 31 cm - width: 24 cm - weight: ~ 8 KG My FLICKR album with photos is here. Daily shots: Suspension: Steering: Night shots:
