12 of them have their own motors at 110 kW each
A unit of China aerospace giant СSSG, the company WSIEC showed unusual mining truck WTW 220E.
This machine is designed to carry 220 tons of cargo. It has a length of 15 m, width of 7.2 m and a height of 6.7 m (with lifted – 14 m).
The most unusual thing about the car is multisupporting chassis. This scheme is widespread on trailers-heavy truck. Its essence lies in the fact that the wheels are of small diameter located at a few in a row on the axis. In this case, the four axes and of the wheels 16.
Thus, multisupporting scheme allows to reduce the load on the ground and use the truck for open cast mining with soft soils. The “trick” WTW 220E, not only in the number of wheels, but that 12 of them have their own motors at 110 kW each. They are powered by a generator that is powered by a turbodiesel Cummins KTA38-S.
