Performance & Engineering

The heart of this concrete mixer truck comprises a meticulously engineered 250kW diesel engine with a displacement of 6.87 liters, delivering the substantial torque and horsepower required for demanding mixing and transportation operations. This powerplant has been specifically calibrated to provide optimal power delivery across varying load conditions, ensuring that the mixing drum maintains consistent rotational speeds even when ascending inclines or navigating challenging terrain. The integration of advanced fuel injection technology contributes to improved combustion efficiency, translating into measurable reductions in fuel consumption during typical operational cycles.

The vehicle's heavy-duty gearbox system transmits power to the rear wheels through a proven 4×2 drivetrain configuration, offering an optimal balance between traction capability and mechanical efficiency. The robust transmission gearing has been specifically selected to accommodate the high torque demands of the mixing drum while providing smooth power delivery during vehicle acceleration and deceleration. Complementing the drivetrain is a set of 11.00R20 tires engineered for commercial heavy-duty applications, delivering excellent grip on construction site surfaces while maintaining acceptable on-road handling characteristics.

The chassis platform has been engineered with high load moment characteristics as a primary design consideration, ensuring structural integrity under the substantial weight of loaded concrete. The 1800+3050+1350mm wheelbase provides a stable platform that effectively distributes the mixing drum's weight across the vehicle's axles, reducing stress on individual components while improving overall handling stability. Precision-engineered bearings throughout the rotating assembly minimize friction losses and ensure smooth drum operation, contributing to the vehicle's reputation for reliability and extended service intervals. The total vehicle weight of approximately 14,700 kg reflects the substantial construction quality that enables this mixer truck to handle the rigors of daily concrete transportation operations.
