The Komatsu 830E is an ultra class haul truck used in open pit mining designed and built in Peoria, Illinois by Komatsu America Corporation, whose parent company is the Japanese held company Komatsu Ltd. [1] [2]
The Komatsu 830E is notable for the rated capacity of 231 t (255 short tons). [1] While large, the 830E's capacity is just under two-thirds the capacity of its two largest competitors, the Liebherr T 282C and Caterpillar 797B. It differs from conventional dump trucks as it uses an electric drive system instead of a transmission/differential drive. The diesel engine is connected to a GE traction alternator then high voltage cables transfer electricity to the two wheel motors at the rear of the truck.
Previously the 830E was made by Dresser Industries, before it was taken over by Komatsu.
