3/4 Axles U-Shape Rear Dump Semi-Trailer For Sale

This 3/4-axle U-shape rear dump semi-trailer is purpose-built for transporting ore, sand, gravel, and bulk materials on mining and construction sites. The U-shape 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 (required for Central Asia; air suspension should be chosen with care), 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 to prevent accidental lowering. Dual-circuit air brakes with WABCO valves and 24V electricals complete the setup; ABS can be omitted to reduce cost, and an automatic rain-proof tarpaulin is available for dusty regions.
