1. Structure & Craft
Fully forged ultra-thick cast steel construction without split welds on stress points for ultimate tensile & compression resistance. Built-in dual hydraulic-rubber shock absorber to eliminate impact from bumpy roads and emergency braking, protecting drawbar, frame and axles. Integrated one-hand self-locking anti-drop mechanism, easy operation without accidental release. Wide support base distributes load evenly to avoid tilt deformation under heavy haulage.
2. Heavy Load Performance
280kN horizontal traction capacity far exceeds WEQ40E & WEQ40F, dedicated for 120–150 ton open pit mine dump and oversize flatbed trailers. 40kN vertical dynamic load handles continuous impact on uphill, downhill and rough mine roads. Wear-resistant sealed ball joint assembly is dustproof, waterproof and mine powder resistant, no oil leakage or jamming for long outdoor service.
3. Application & Compatible Tractors
Domestic: Heavy dump semi-trailers for large open coal & metal mines, 120–150 ton oversize equipment transport, port ultra-heavy flatbed trailers.
Export: Cross-border ore & earthwork haulage for open mines in Mongolia and Central Asia.
Tractor Match: 700HP+ 8×4 / 6×4 heavy-duty HOWO & SHACMAN tractor units.
4. Supply & After-Sales
Retail price 2600 RMB per unit, tiered discount for bulk orders. Triple factory inspection for tensile force, hydraulic tightness and lock reliability. Nationwide domestic logistics, full tractor+trailer package export service. 12-month warranty for cast steel housing and hydraulic assembly, long-term original spare parts supply.
