Haul truck

Haul trucks are off-highway, rigid dump trucks specifically engineered for use in high-production mining and heavy-duty construction environments. Haul trucks are also used for transporting construction equipment from job site to job site. Some are multi-axle in order to support the equipment that is being hauled.

Description

Most haul trucks have a two-axle design, but two 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 long tons; 36 t) to 496 short tons (443 long tons; 450 t).

Large quarry-sized trucks range from 40 short tons (36 long tons; 36 t) to 100 short tons (89.3 long tons; 90.7 t). A good example of this is the Caterpillar 775 (rated at 70 short tons [62 long tons; 64 t]).[2] Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks.

Ultra class

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 (268 long tons; 272 t) or greater.[3] As of October 2013, the BelAZ 75710 has the highest payload capacity, 450 metric tons (440 long tons; 500 short tons).[4]
