Off-road dump trucks have several special suspension designs to handle various complex road conditions. For example, the MAN HX series off-road heavy trucks use leaf spring suspension, while the SX series is equipped with coil spring suspension.

US military'sM977A4 truckuses the HAUSKO TAK-4 hydro-pneumatic suspension system. This suspension system has a long suspension travel, providing strong off-road capability and leveling capability. China'sShaanxi Automobile SX2550 10x10 military truckalso uses a similar suspension system, improving the vehicle's off-road performance.
Unimoghas an excellent suspension system. Its design uses an integral axle with coil spring damping, and the frame has a strong ability to withstand torsional stress. Through an offset frame design and welded tubular structure, the frame's torsional flexibility is enhanced. The cab, engine, and gearbox are connected to the frame at three points, giving the vehicle a certain degree of torsional freedom when the frame is twisted.
The hill-climbing chassis suspension design of the Mercedes-Benz 6x6 military off-road truck is also quite outstanding, providing the vehicle with excellent off-road performance.
United Heavy Truck Off-Road Special Chassisalso performs excellently. Its engine is a 350 horsepower National VI b emission standard diesel engine, the chassis uses a Tatra central spine structure and independent suspension, and the transmission is an Allison AT imported transmission. The body uses an all-steel flat-top cab and uses highly reliable CAN bus structured electrical equipment. The body attitude control uses a pure mechanical valve-controlled bellows air suspension.
