What is a rear dump trailer?

A rear dump trailer is a type of semi-trailer primarily used for transporting and dumping bulk materials. This setup includes a tractor connected to a semi-trailer via a saddle, creating a semi-trailer train configuration. The hydraulic lifting system in a rear dump trailer is key to its functionality, enabling the trailer bed to tilt for unloading. This system includes several essential components: a power take-off (PTO) unit connected to the gearbox, a hydraulic pump, a lifting valve, a gas control valve, a limit valve, a hydraulic cylinder, a hydraulic oil tank, and high- and low-pressure oil pipes. Together, these parts work seamlessly to lift the trailer bed, allowing for efficient rear unloading of materials.

Made of high-strength Q700 steel,, which has better tensile strength and yield strength. Yield strength Mpa ≥ 650Mpa,sile strength ≥ 700-880, elongation 18-25.this material has strong corrosion resistance, is hard and sturdy, and is suitable for transporting materials such as hard stones.

What are the advantages of U-shaped rear dump semi-trailer ?

The U-shaped rear dump semi-trailer offers several advantages compared to traditional square-shaped cargo boxes. Unlike the conventional design, which typically relies on thickening the box panels and reinforcing the frame structure for added strength, the U-shaped cargo box introduces an innovative design that reduces deadweight through a more efficient structural system. By utilizing high-strength materials for the cargo box panels, the U-shaped design maintains the necessary strength while cutting down the overall weight by more than a ton. This reduction in deadweight significantly enhances the load utilization factor, allowing for better efficiency in transporting cargo.

Our U-shaped rear dump semi-trailer features a powder coating process, which utilizes electrostatic charges to evenly apply powder paint onto the vehicle’s surface. This advanced coating technique significantly enhances the vehicle’s durability and extends its service life. After the powder is applied, it is baked to form a smooth, uniform surface that offers improved wear resistance and corrosion protection. This process ensures that the vehicle remains in excellent condition for a longer period, even under challenging operating conditions.
