Performance & Engineering

At the heart of this Sinotruk HOWO tractor truck lies the formidable Weichai WD615.47 diesel engine, a powerplant renowned for its exceptional reliability and robust construction. This 6-cylinder, 8-liter-plus displacement engine generates an impressive 375 horsepower with maximum torque output ranging between 1500-2000Nm, providing the sustained pulling power essential for heavy-load operations. The engine's proven design incorporates advanced fuel injection technology optimized for Euro 2 emission standards, ensuring compliance with regional environmental regulations while maintaining competitive fuel consumption rates.

The drivetrain features a heavy-duty Sinotruck manual transmission paired with the powerful engine, delivering smooth and precise gear changes under varying load conditions. The 10-forward and 2-reverse gear configuration provides operators with optimal gear ratios for diverse operational scenarios, from low-speed maneuvering on rough terrain to high-speed highway cruising. This transmission design has accumulated billions of kilometers of proven service history, demonstrating exceptional durability even under the most demanding operating conditions encountered in construction and mining applications.

The chassis engineering of the HOWO 6x4 incorporates a reinforced ladder-type frame with optimized crossmembers, providing exceptional torsional rigidity while maintaining the structural integrity required for heavy-duty hauling. The robust suspension system, featuring appropriate spring configurations for the front and rear axles, effectively absorbs road irregularities while protecting both cargo and the vehicle itself from excessive vibration and shock loads. Combined with the spacious 8245x2550x3450mm overall dimensions and generous 5400x2300x1500mm cargo platform, this heavy truck delivers the payload capacity and durability that professional operators demand.
