Performance & Engineering

The heart of this heavy-duty dump truck is the Weichai WD615.47 engine, a legendary powerplant in the commercial vehicle industry known for its exceptional durability, fuel efficiency, and ease of maintenance. This 9.726-liter six-cylinder inline diesel engine delivers a maximum output of 371 horsepower at 2,200 rpm, with peak torque exceeding 2,500 Nm available at just 1,300-1,500 rpm. This torque characteristics provides exceptional low-end pulling power essential for heavy-load starts on inclines and soft ground conditions commonly encountered at construction sites and quarries. The engine's robust design incorporates advanced fuel injection technology and optimized combustion chamber geometry to achieve the ideal balance between power output and fuel consumption.

Power is transmitted through a FAST manual transmission featuring eight forward gears and one reverse gear, enabling operators to select the optimal gear ratio for varying load conditions and terrain gradients. The synchronized shifting mechanism ensures smooth power transitions while the wide gear spread accommodates both low-speed maneuvering and high-speed highway cruising. The 6x4 drive configuration provides excellent traction distribution across all four rear wheels, reducing ground pressure per tire and improving stability on uneven or soft surfaces. The vehicle's 10-tire configuration with dual rear axle setup contributes to its exceptional 30-ton gross vehicle weight capacity while maintaining ride comfort and tire longevity.

The chassis architecture features a reinforced ladder-type frame constructed from high-tensile steel, providing the structural rigidity necessary to withstand the dynamic stresses of heavy-load tipper operations. The suspension system employs heavy-duty leaf springs on both front and rear axles, designed to absorb road shocks while maintaining payload stability. The braking system utilizes air-assisted drum brakes on all wheels, providing consistent stopping power even under full payload conditions. With a fuel tank capacity of 300-400 liters, this dump truck offers extended operating range between refueling stops, minimizing downtime and improving overall fleet productivity.
