1. Structure & Craft
One-piece forged drawbar ring made of thick cast steel without welding seams, ultimate tensile strength far above rated 360kN. Dual front and rear rubber shock absorbers eliminate longitudinal impact and reduce frame & drawbar fatigue. Auto spring lock with stainless steel safety chain prevents accidental unhooking on bumpy roads. 4-hole square mounting flange matches standard mine vehicle drawbar dimensions, sealed hydraulic connector at rear for dust & leak resistance.
2. Heavy Load Performance
360kN rated horizontal traction leads the same price range, designed for 100–160 ton heavy trailers. 26kN vertical dynamic buffer load handles continuous impact on rough mine slopes and pits. Easy open-close ring hook for simple draw pin inspection & replacement. Separable rubber buffers cut maintenance cost, stable operation under mine dust, rain and snow.
3. Application & Compatible Tractors
Domestic: Open coal & metal mine dump semi-trailers, long-distance oversize equipment transport, port heavy flatbed trailers.
Export: Cross-border ore & earthwork haulage trailers for mines in Mongolia and Central Asia.
Tractor Match: 6×4 / 8×4 high-power heavy-duty HOWO & SHACMAN tractors.
