Detailed Description:
- Advanced Material Science:The entire body is fabricated from imported HARDOX 500 wear-resistant steel, providing 2–3 times the service life of conventional Q345 steel, dramatically reducing maintenance and replacement costs in abrasive environments.
- Payload & Weight Optimization:Available in 40/60/80/100-ton configurations, the U-shaped design achieves a 10–15% reduction in tare weight compared to conventional square-body trailers, directly increasing revenue-generating payload capacity.
- Intelligent Unloading Design:The smooth, continuous inner surface and optimized hopper angles eliminate material bridging and sticking, ensuring a complete, rapid discharge in under 2 minutes, even with moist clay or sticky aggregates.
- Enhanced Road Stability: The U-profile inherently lowers the center of gravity by approximately 15%, significantly improving roll stability during cornering and on uneven haul roads, which is critical for operator safety and load protection.
- Key Markets: Large-capacity aggregate transport, metal/non-metal mining operations, and major infrastructure projects requiring high-volume material movement.

Frequently Asked Questions
How much can this dump semi-trailer carry?
This 4-axle dump semi-trailer is rated for 40T of payload. The U-shaped or square body is matched to the axle set and the kingpin rating so the combination stays legal and stable at full load.
What materials does it handle best?
Sand, gravel, crushed stone, ore, grain and other bulk material. The smooth-sided body discharges cleanly, which matters for sticky or damp loads that bridge in a conventional tipper body.
What is the difference between a U-shape and a square dump trailer?
A U-shape body has curved sides, so wet or sticky material slides out without bridging. A square body carries slightly more volume for the same footprint and suits dry, free-flowing aggregates. Choose U-shape if your material is damp.
Which axles and suspension are fitted?
This unit runs 4-axle axles with a heavy-duty mechanical or air suspension. Air suspension is preferred where road damage is a concern or where the trailer is used for high-value or fragile cargo.
How is the trailer shipped?
Dump semi-trailers ship in containers or by breakbulk depending on length and axle count. We supply the loading plan, tie-down specification and full export documentation with every shipment.
Why Buy From ZS Truck
- Factory-direct pricing — You buy from the manufacturer, not through a trading layer, so the price reflects the build cost plus a single margin.
- Built to your specification — Drive formula, steering side, emission standard, axle count and body configuration are set to your market before production starts.
- Export documentation handled — Commercial invoice, packing list, bill of lading, certificate of origin and conformity documents are prepared with every shipment.
- Spare parts and support — Every order ships with a recommended spare parts kit, and we quote ongoing parts supply for the consumables that wear first.
We ship regularly to Nigeria, Ghana, Tanzania, Kenya and Zambia, where buyers typically specify Euro 2 or Euro 3 engines for fuel tolerance and easy servicing.
ZS Truck (Shandong Zhongsheng Vehicle) manufactures and exports trucks and semi-trailers from Shandong, China to buyers in Africa, the Middle East, Southeast Asia and Latin America. Contact us with your specification and destination port for a factory-direct quotation.
