Haul truck

Haul truck in Quebec, Canada, with people for scale

Haul trucks are off-highway, two-axle, rigid dump trucks specifically engineered for use in high production mining and heavy-duty construction environments. Two very well known models from the 1970s the 350T TerexTitan and 235TWabco 3200/B were of a three axle design. Haul truck capacities range from 40 short tons (36 t) to 400 short tons (363 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)). Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks.

Standard mining trucks fall into these classes 130T, 150T, 190T, 240T, 320T, and 400T (ultra-class). As of 2013, BelAZ 75710 has the highest payload capacity, 450 metric tons.

Ultra Class

Liebherr T 282B ultra class haul truck.

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.
