Haul trucks are off-highway, rigid dump trucks specifically engineered for use in high-production mining and heavy-duty construction environments.


Most haul trucks have a two-axle design, but two very well known models from the 1970s, the 350T Terex Titan and 235T Wabco 3200/B, had three axles. [1] Haul truck capacities range from 40 short tons (36 t) to 496 short tons (450 t).

Large quarry-sized trucks range from 40 to 100 tons. A good example of this is the Caterpillar 775 (rated at 70 short tons (64 t)).[2] Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks.

Ultra class[edit]

The largest, highest-payload-capacity haul trucks are referred to as ultra class trucks. The ultra class includes all haul trucks with a payload capacity of 300 short tons (272 t) or greater.[3] As of October 2013, the BelAZ 75710 has the highest payload capacity, 450 metric tons.[4]


As the world largest six-wheeled dump truck, the XDE400 electric drive dump truck can accommodate 400 Metric tons. It is equipped with a XCMG-patented AC variable frequency traction system to improve its traction and ambling capacity and also achieve higher efficiency.
