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.

As a rule, these dump trucks can be distinguished from other trucks (in particular, dump trucks) by the following features:

the tipper body is made of very strong steel plate; its front is extended above the driver's cab to protect the cab; the entire bottom, or rear of it, points upward;in some cases the driver's cab is only half the width of the truck;no axle suspension;powerful brakes;limited speed and operating range;special tires used for driving on the ground;due to the robust design the ratio of dead weight to payload does not exceed 1:1.6the body can be heated by exhaust gases to prevent the transported material from sticking or freezing.Dump trucks are classified by:

type of unloading (inclined or forced);the direction of discharge (side, rear);type of body (hopper, platform, sliding hopper, sliding platform).
