The dump semi-trailer utilizes a front-mounted hoist for rear-discharge unloading; its cargo body features a framework structure with corrugated panels and incorporates aluminum alloy components-such as fenders, toolboxes, landing legs, and wheels-alongside high-strength steel, with weight-reduction holes punched into the chassis cross-members to lower the vehicle's curb weight.
The lifting mechanism employs a front-mounted single-cylinder hoist, with a stabilizing bracket positioned beneath the cargo body; the rear of the body features a widened four-point hinge design, while the rear of the chassis utilizes X-shaped cross-bracing to connect the two frame rails.
The T6 aluminum alloy rear-dump trailer from the U.S. company Hicks employs bolted and riveted assembly methods to prevent the reduction in aluminum strength caused by welding, and utilizes an ultra-high molecular weight polyethylene (UHMW) liner to minimize cargo residue.
Heavy-duty dump semi-trailers utilize heavy-duty hydraulic cylinders featuring larger diameters and higher load-bearing capacities to ensure stable lifting operations.
