3 Axles Shape Rear Dump Semi-Trailer For Sale

This 3-axle shape rear dump semi-trailer is purpose-built for transporting ore, sand, gravel, and bulk materials on mining and construction sites. The high-strength body discharges cleanly with no residual material, while the front-mount hydraulic cylinder provides powerful and reliable dumping.

The U-shape high-strength steel body features an 8mm floor and 6mm sides for maximum resistance to abrasion and impact, making it ideal for rock and ore haulage. The rounded bottom ensures material discharges completely with no sticking.

Fitted with a 3.5-inch (90#) bolted kingpin, 28T JOST dual-speed heavy-duty legs, mechanical leaf spring suspension, and 3×13-ton FUWA axles, the trailer delivers outstanding durability on rough terrain.

The front-mount HYVA-type multi-stage hydraulic cylinder lifts the body to a 45–50° angle with a safety valve. Dual-circuit air brakes with WABCO valves and 24V electricals complete the setup; an automatic rain-proof tarpaulin is available for dusty regions.
