The WABCO 3200 is a large dump truck made by the US construction machinery manufacturer WABCO Vehicle Control Systems in the 1970s.
Development history
In terms of dimensions and payload, the WABCO 3200 is the largest dump truck in WABCO's Haulpak range, the prototype of which was completed in 1970. This was able to transport material of up to 181 tons (200 short tons ) in its trough , making it the most powerful dump truck at the time. Series production began in 1971, but was switched to the improved model WABCO 3200B in 1974, which had a payload of 227 tons (250 short tons) with the same engine. Production stopped in the early 1980s after around 48 vehicles were built.
technology
The two rear axles with double tires of the three-axle WABCO 3200 were driven by electric traction motors. It draws its power from a turbocharged V12 four-stroke diesel engine with a displacement of 126.8 liters of the type 12-645-E4 from GM , which was originally designed for diesel locomotives . The engine has 12 cylinders and delivers 2000 hp (1491 kW) at 900 revolutions per minute. The maximum torque is 11671 lb f · ft (15.8 kN · m) The Model 3200B was equipped with an engine of 2250 hp (1678 kW) from 1976. The traction motors (one for each rear axle) each had an output of 1125 hp (839 kW). The WABCO 3200 had a diesel-electric drive that made manual gearboxes and clutches superfluous, which in particular reduced maintenance costs. The diesel engine drives a three-phase generator , which provides the electrical energy for the electric motors on the axles. One of these electric motors is located on each rear axle, which drives a geared planetary gear on the wheels. The cab is located above the left front wheel and can be reached using a ladder at the front of the vehicle. The tipping skip can be moved from the horizontal into the tipping position with two hydraulic cylinders .
