4-Axle U-Shaped Rear Dump Semi Trailer

A: It is mainly used for transporting bulk cargo such as sand & gravel, ore, coal, muck, and construction waste. It is also suitable for bulk goods with good fluidity like grain, making it the mainstream transport model for mines, infrastructure construction sites, and sand & gravel yards.

 A: The U-shaped cargo body has no right-angle dead corners, resulting in very little cargo residue during unloading, eliminating the need for manual cleaning. Its overall structure has more even stress distribution, stronger impact and deformation resistance, and a lighter dead weight, which increases the effective payload capacity.

 A: The 4-axle layout distributes the total vehicle weight, enhancing the overall payload capacity to meet heavy-duty transport needs. It also reduces ground pressure, complying with road load limits in most regions, and improves driving stability and passability.

 A: The mainstream design uses a hydraulic cylinder lifting structure (mostly single or double front cylinders), with a lifting angle typically reaching 45°–55°, enabling fast unloading. The rated lifting force of the system matches the vehicle's rated payload, ensuring stable lifting under heavy loads.
