Performance & Engineering

The WEICHAI 400HP engine powering this heavy-duty dump truck exemplifies modern diesel engine technology, delivering 294kW of continuous power output through a proven 6-cylinder configuration. This Euro 2 compliant powerplant combines robust construction with fuel efficiency optimization, making it particularly suitable for construction transportation applications where sustained operation under heavy loads is the norm rather than the exception. The engine's superior torque characteristics in the 1500-2000Nm range ensure that the vehicle maintains optimal performance even when climbing gradients or traversing soft ground conditions typical of active construction sites.

The FAST 12-speed automatic transmission paired with this powertrain represents the gold standard in Chinese commercial vehicle drivetrains, offering seamless gear engagement and intelligent shift logic that adapts to varying load conditions. The transmission's robust internal components are designed to handle the high torque outputs generated by the WEICHAI engine, ensuring long service life even under sustained heavy-duty operation. With two reverse gears available, operators benefit from enhanced maneuverability in confined loading and dumping zones common at construction sites and material processing facilities.

The chassis and suspension system of this SINOTRUK HOWO dump truck have been engineered for maximum durability under extreme loading cycles. The vehicle features a comprehensive 12-tire configuration with 12.00R20 18PR radial tires mounted on a heavy-duty wheelbase measuring 1800+2575+1400mm, providing exceptional stability and load distribution. The air suspension driver's seat reduces operator fatigue during extended shifts, while the advanced braking system incorporating ABS and ESC ensures controlled deceleration and enhanced safety when transporting heavy loads on construction site access roads and public highways alike.
