Komatsu To Launch 860E Super-large Dump Truck Powered By Siemens’ AC Motor

Here is an image of the Komatsu’s new 860E-1K model electric-drive rigid dump truck, recently displayed at the 860E at the MINExpo INTERNATIONAL 2008 in Las Vegas.


Komatsu teamed up with Siemens for the development of new electric drive systems. The newly developed electric drive system consists of a generator, AC motor, inverter, final gear and other components. The 860E integrates Siemens’ leading-edge electric components and Komatsu-developed and manufactured mechanical components, such as the final gear.

A factory installed trolley-cable option is also available for the 860E. Under the trolley system, pantograph-mounted dump trucks receive electric power from the trolley cable extended over their travel routes to drive their AC motors. The trolley system supports high-climbing performance.

Also under this system, dump trucks use electricity generated at the mine instead of electricity generated by their own engines, which can extend their engine life to a great extent and cut down fuel expenses.
