Komatsu 830E
From Wikipedia, the free encyclopedia
The Komatsu 830E is an ultra class dump truck used in open pit mining designed and built in the United States (Peoria, Illinois) by the Japanese company Komatsu.[1] [2]
The Komatsu 830E is notable for the 231,000 kilograms capacity of its bucket.[1] While large, the 830E's capacity is just under two-thirds the capacity of its two largest competitors. the Liebherr T 282B and Caterpillar 797B. Like the German designed Liebherr model, and its larger stablemate, the Komatsu 930E, the 830E is a hybrid diesel-electric vehicle whose wheels are driven by either direct current or alternating current electric motors (830E-AC). The American designed Caterpillar uses a traditional mechanical transmission, whose diesel motors connect to its driving wheels through a traditional mechanical transmission and drive train.
Previously Dresser Industries made the 830E before it was taken over by Komatsu.
