Engineered for quarry, mining, and high-frequency bulk material transport under extreme off-road conditions.
This 4 axle 40CBM mining dump semi trailer is designed for continuous high-impact loading in mining and quarry environments. It solves three core problems: frame fatigue, axle overload, and hydraulic instability under full payload conditions.
The dump body uses Q550/Q690 high tensile steel, engineered for abrasive materials like ore, coal, and stone. Compared with Q345 steel, it significantly improves fatigue resistance and reduces deformation risk.
High impact resistance for mining ore loading
Reduced welding stress concentration
Extended service life under harsh conditions
Lower maintenance cost per ton transported
The box-type subframe improves torsional rigidity and prevents structural fatigue caused by uneven mining road conditions. It distributes stress evenly across the chassis during slope climbing and rough terrain operations.

The front-mounted multi-stage hydraulic cylinder ensures stable lifting under full 40CBM payload. It reduces material residue and improves unloading efficiency in mining operations.
Stable lifting under full load conditions
Controlled tipping angle 45–50°
Reduced hydraulic pressure loss
Improved unloading speed and safety
The 4 axle configuration reduces per-axle stress and improves tire lifespan in high-frequency mining transport cycles. Air suspension improves ground adaptability on unpaved roads.
18%–25% axle load fluctuation reduction
Lower tire wear rate
Better braking stability on slopes
