The capacity of a dump truck varies with its size. Smaller ten-wheel dump trucks haul about 10 cubic yards of material, equivalent to approximately 13 tons. The largest road-going dump trucks are the Super 18 varieties, which can haul up to 40 tons of material.
Larger non-road-going dump trucks are used in surface mines and quarries and known as haul trucks. These large high-capacity vehicles, like the Caterpillar 797F, typically have payloads of 400 tons, ten times that of the Super 18. This capacity is equivalent to a range between 315 and 350 cubic yards of material. The 797F is 51.5 feet tall with the body raised and 49.5 feet long.
