The Beiben 6×4 U-shaped dump truck is a heavy duty truck designed for bulk material transportation in mining and construction projects. Equipped with a 420 HP WP12 engine and double reduction axles with Mercedes Benz technology, it delivers powerful and reliable performance. Its core advantage lies in the high strength steel U shaped cargo body, which enables residue free discharging with little material adhesion. Featuring lighter tare weight and a lower center of gravity, the truck runs stably and safely. Supported by a dual circuit brake system and auxiliary brake, it handles heavy load operations effortlessly. Widely used for frequent loading unloading tasks of sand, gravel, coal and other materials, it serves as an efficient and durable workhorse for engineering transportation.

Applications of Beiben U-shaped box tipper truck⇓
The Beiben 6×4 U shaped dump truck is primarily designed for short haul transport scenarios that require efficient, clean bulk material transfer. Its common applications include:
• Mining and quarry operations: Specifically used for the extraction and transfer of coal, iron ore, copper ore, and other mineral resources. Its high strength and impact resistant design is capable of handling harsh working conditions.
• Infrastructure and construction projects: In road construction, bridge building, and other projects, it is responsible for large scale transfer of building materials such as sand, gravel, and earth.
• Urban muck and environmental sanitation: Thanks to the U shaped body's non sticking properties, clean dumping, and good sealing, it is highly suitable for the removal and transport of urban construction waste and muck, effectively reducing spillage and dust emissions.

U-shaped VS Rectangular Dump Truck Body⇓
|
Comparison Item |
U‑Shaped Dump Body |
Rectangular Grid‑Reinforced Dump Body |
|
Body Structure |
Arc‑shaped floor without right‑angle dead corners, integrally bent from high‑strength steel plate |
Flat‑bottom rectangular container; reinforced "grid‑shaped" frame formed by external vertical and horizontal ribs; multiple longitudinal beams at the bottom for load‑bearing |
|
Dead Weight & Load Utilization Factor |
Lighter curb weight (normally reduced by about 1 ton); lower center of gravity, better driving stability, reduced cargo spillage |
Heavier tare weight; slightly larger internal volume; strong anti‑sag performance under heavy‑load conditions |
|
Discharging Performance |
Smooth inner wall with no dead corners, thorough unloading. Hardly sticky for wet soil, coal powder and clay; fast dumping speed |
Material residue easily accumulated at right‑angle corners. Wet cargo is hard to unload completely, resulting in residual loss |
|
Impact‑resistance & Wear‑resistance |
High‑strength steel plate; arc‑shaped floor cushions impact from rocks, ideal for ore haulage |
Thickened floor + dense reinforcing ribs; excellent anti‑bumping and heavy‑duty capacity, suitable for large‑size heavy stones and extreme heavy‑load working conditions |
|
Procurement Cost |
Relatively high cost; complex superstructure manufacturing process |
Cost‑effective, easy maintenance and readily‑available spare parts |
|
Recommended Working Conditions |
Mines, ore, coal, muck, wet clay; scenarios requiring frequent dumping and stable transportation |
Large‑size rocks, construction waste, short‑distance heavy‑load shuttle transport; construction sites where maximum cargo‑box volume is required |
