The U-shaped rear dump semi-trailer is a mainstream hydraulic tipper trailer specially designed for loose bulk cargo transportation, widely exported to Africa, the Middle East, Southeast Asia and Latin America. Different from traditional square dump trailers with right-angle corners, it adopts an integrated curved U-bin structure, mainly used to haul sand, gravel, coal, mine ore, construction waste and soil for infrastructure, mining and earthmoving projects. It matches all mainstream tractor heads like HOWO, SHACMAN and FAW, and becomes the top pick for medium and long-distance bulk haulage fleets due to its efficient unloading performance.
The smooth arc bottom and side walls eliminate dead corners inside the cargo box. Sticky mud, wet sand and fine ore will not stick to the inner wall during tipping, which greatly cuts manual cleaning work and unloading time per trip. Without extra inner stiffeners, the whole body weight is lighter while structural strength stays solid, raising actual payload without violating local weight limit rules.
Trailer chassis uses high-strength integrated I-beam steel for strong anti-torsion capacity on bumpy mine roads. Cargo bin is made of T700 high-tensile wear-resistant steel plate, resisting impact from sharp stones and long-term abrasion. Surface undergoes full sandblasting and anti-rust paint treatment to adapt rainy, dusty overseas environments.
Before placing orders, buyers need to confirm local road axle load limits, maximum vehicle length and height regulations, so manufacturers can adjust frame thickness, axle quantity and bin size accordingly. For daily maintenance, regularly check hydraulic cylinder seals, axle lubrication and brake systems to extend the whole trailer service life. Most trailer factories provide 12–18 months warranty for core components and long-term spare parts supply support for bulk purchasers.
