Haul truck

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

Haul trucks are denominated by their payload capacity, by weight (variously in tons, tonnes, and kg).

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.

[3] Quarry operations (which produce payloads that have value) are typically employ smaller trucks[why?]

than mining operations (such as removing undesirable overburden, an expense).
