4 Axles Rectangular Rear Dump Semi-Trailer For Sale

This 4-axle rectangular rear dump semi-trailer is purpose-built for transporting large rocks, earth, and heavy bulk materials on mining and construction sites. The rectangular body with vertical walls is designed for blocky material that a U-shape body cannot handle as efficiently.

Unlike a U-shape body, the rectangular square box has vertical walls, which is ideal for large rocks and earthwork. Note that wet clay and fine sand can stick to the corners, so an Africa export heavy-duty configuration with a 10mm floor and 8mm wear-resistant high-strength steel sides is available.

Fitted with a 3.5-inch (90#) bolted kingpin, 28T JOST dual-speed heavy-duty legs, and 3×13–16-ton FUWA heavy-duty axles, the trailer can be configured with standard leaf spring or Rob-Spring single-point suspension for rough African mine roads.

The original HYVA front hydraulic cylinder provides reliable dumping power, and a hydraulic automatic tailgate is available as a top choice for mining operations. Dual-circuit air brakes with WABCO valves and 24V electricals complete the setup.
