U-Shaped Rear Dump Trailer for Heavy Bulk Material Transport
High-strength U-shaped rear dump trailer designed for efficient unloading of bulk materials.
U-Shaped Rear Dump Trailer Detailed Description
The U-Shaped Rear Dump Trailer is engineered for reliable transportation and efficient unloading of bulk materials such as sand, stone, coal, and ore. Its U-shaped cargo body minimizes material residue during unloading, ensuring smooth and complete discharge.
Built with high-strength steel and reinforced structural design, this trailer delivers excellent durability and stability under heavy-duty operating conditions. The rear tipping system provides balanced unloading performance, making it suitable for construction sites, mining operations, and infrastructure projects.

U-Shaped Rear Dump Trailer Features
- No Dead Spots: Material naturally slides towards the center under gravity, leaving minimal residue.
- High Strength: The arched structure acts like a bridge, better distributing the pressure of the load against the walls, resulting in a lighter yet stronger body for the same weight.
- Lightweight: Compared to a rectangular body, it reduces tare weight for equivalent strength, increasing payload capacity.
Hydraulic Lifting System:
- Core: A multi-stage (usually 4-5 stage) front-mounted hydraulic cylinder, installed between the front of the body and the subframe.
- Power: A PTO (Power Take-Off) from the tractor unit drives the hydraulic pump.
- Lifting Angle: Maximum tipping angle can exceed 70 degrees, relying on gravity for complete self-unloading.
- Control: The operator controls lifting and lowering via a remote control or manual valve from outside the vehicle for safety
Chassis and Frame
Subframe:
This is a robust base frame connected to the axles via the suspension. The body's tipping pivot is fixed to this subframe.
It bears the weight of the entire loaded body and remains stable during lifting.
Main Beams:
During tipping, only the subframe and axles remain on the ground. The entire body, including its main beams, is lifted.
The beams must have extremely high torsional strength to withstand the significant stresses of lifting and unloading.
