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

Description[edit]

Most haul trucks have a two-axle design, but two very well known models from the 1970s, the 350T TerexTitan and 235TWabco 3200/B, had three axles. [1] 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.

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.[2] As of October 2013, the BelAZ 75710 has the highest payload capacity, 450 metric tons.[3]
