Off-road dump truck
DAC 120 DE Earth-hauling Dump
Liebherr
Off-road dump trucks more closely resemble heavy construction equipment or engineering vehicles than they do highway dump trucks. They are used strictly off-road for mining and heavy dirt hauling jobs. The current largest off road haul trucks are the Liebherr T282B and the Caterpillar 797B, which both have payloads of 400 short tons. Even though these trucks are similar in capacity the Caterpillar is referred to as a mechanical truck since it uses a big diesel engine(s, sometimes two) and big transmissions to power the rear wheels. The Liebherr is referred to as a Diesel-Electric Truck since it uses a diesel engine linked to an alternator that generates electricity which is converted to AC used to power two giant electric motors found on the rear wheel assemblies, similar to a locomotive (it is a series plug-in hybrid). Besides Liebherr and Caterpillar, Hitachi, Terex, Komatsu and others also fabricate such off road haul trucks in different capacities.
