Product Features & Applications

Top heavy-duty hydraulic WEQ45 drawbar coupler, fully forged ultra-thick cast steel housing with rated traction load up to 280kN, compatible with 150-ton mine and oversize transport trailers. Multi-layer composite hydraulic shock absorption, high-strength integrated lock mechanism with excellent tear & impact resistance, specially designed for harsh open-pit mine roads, matches high-power HOWO & SHACMAN tractors. Unit price 2600 RMB, full container bulk export supply available.

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.
