Heavy-Duty Rear Dump Semi Trailer (30T–100T Payload for Mining & Construction)
ENXIN rear dump semi trailers (also known as tipper semi trailers or end dump trailers) are engineered for heavy-duty haulage of aggregates, sand, gravel, construction debris, and mining ores across rugged terrains in Africa, Central Asia, and South America.
Manufactured in our Liangshan facility using premium Q345B high-tensile steel or ultra-wear-resistant T700 / BST1000L steel, the tipper body is shaped and reinforced to withstand severe abrasive impact while maintaining balanced stability during hydraulic tipping.
Key Engineering & Tipping Safety Features
- Heavy-Duty Front-Lifting Hydraulic Cylinder: Equipped with a multi-stage hydraulic telescopic tipping cylinder (HYVA / FC series optional), providing fast cycle times and smooth lifting. Integrated with a pneumatic tipping control valve and mechanical limit valve to prevent over-extension.
- Reinforced Mining-Grade Main Beam: Fabricated from Q345B / BST1000L high-tensile steel with automatic submerged arc welding. Deep I-beam structure prevents bending or torsional deformation under concentrated off-center loading.
- Anti-Deformation Cargo Body: U-shaped (half-pipe) or rectangular bucket designs. Standard 8mm checkered floor plate and 6mm high-strength sidewalls (customizable with wear-resistant liners for abrasive granite and iron ore transport).
- Automatic Mechanical Tailgate Locking: Heavy-duty rear door with auto-releasing mechanical locks and safety chains, ensuring reliable cargo retention during transit and rapid material discharge upon tipping.
- Heavy-Duty Running Gear & Stable Pivot: Genuine FUWA / BPW / Fengbao 13T or 16T axles, coupled with a wide-span heavy mechanical suspension and reinforced rear tipping hinge shaft (100mm solid steel pin) to maximize anti-rollover safety during high-angle dumping.

Frequently Asked Questions (Buyer Decision Guide)
Q: How do you prevent rollover when dumping on uneven ground?
A: Our tipper chassis uses a lowered center-of-gravity design, widened rear hinge span, and high-strength torsional box crossmembers. Operators should ensure the truck and trailer are aligned straight on compacted ground before lifting.
Q: What is the benefit of T700 steel over standard Q345B for dump bodies?
A: T700 steel offers higher yield strength (~700 MPa vs ~345 MPa). Using T700 reduces the tare weight of the bucket by 15–20% while providing greater impact resistance against heavy granite and jagged ores, allowing you to carry more legal payload.
Q: What is the delivery lead time for dump trailers?
A: Standard specifications with Chinese hydraulic systems ship in 15 to 20 working days. Custom orders equipped with genuine HYVA cylinders or specific bucket dimensions ship in 25–30 days.
