LeTourneau Technologies Australia will show its 1050 hp diesel-electric D-950 wheel dozer with 27m3 blade capacity on Stand 108 during AIMEX 2007 – Asia Pacific’s International Mining Exhibition, to be held at Sydney’s Olympic Park from September 4 to 7, 2007.
The D-950 has independent electric motors in each wheel, and uses switched-reluctance (SR) traction motors, which do not use brushes or commutators.
This drive system has wider power band and higher output-to-weight ratio than conventional DC traction motors and does away with the differentials, transmissions, torque converters and drive shafts of a mechanical drive machine.
This drive system eliminates two of the three main causes of tyre wear: slippage and scrubbing. Substantial fuel savings are also claimed. The drive system is already proven in the L-950 loaders operating in Australia.
