Diecast Masters 1:87 Caterpillar 772 Off-Highway 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

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.  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 to 100 short tons (36 to 89 long tons; 36 to 91 t). A good example of this is the Caterpillar 775 (rated at 70 short tons [62 long tons; 64 t]). Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks.
