Extra heavy-duty dump trucks are operated under severe conditions and usually do not reach the manufacturer's specified service life (at the design 450 thousand km the actual mileage is 150-250 thousand km). Basic designs of dump trucks operate in modes of multi-cycle alternating dynamic loads during excavator loading and when driving on quarry roads. These loads determine the reliability and durability of assemblies and systems of the dump truck
Heavy-duty mining dump trucks have two main damping systems: air-hydraulic suspensions and tires.
