Core Advantages & Performance

Exceptional Power & Fuel Efficiency

At the heart of this vehicle lies the WP12.400E201 Weichai engine, delivering 400 horsepower of relentless pulling capability. Mated to the HW19710 10-speed forward gearbox, this powertrain configuration ensures exceptional gradeability, allowing the truck to conquer steep inclines without losing momentum. The precise gear ratios are calibrated to keep the engine in its optimal RPM range, translating to remarkable fuel economy even when operating at a maximum gross combination weight.

Superior Load Capacity & Chassis Stability

Built upon a rugged 10-wheel chassis architecture, the truck features dual 16-ton heavy-duty rear axles engineered for extreme mechanical stress. This robust foundation comfortably supports a 60-ton comprehensive load capacity. The optimized suspension system absorbs severe road shocks, ensuring that the tires maintain a firm, continuous grip on the road surface, which is critical for stability when hauling heavy, shifting loads across unpredictable terrains.

Aerodynamics & Energy Optimization

Beyond raw mechanical strength, the exterior design incorporates a scientifically contoured wind deflector. This aerodynamic enhancement significantly cuts down frontal wind resistance during high-speed highway transit. By minimizing drag and mitigating the destabilizing effects of crosswinds, the truck achieves a lower overall drag coefficient, directly contributing to reduced fuel consumption and enhanced driving stability over long distances.

Optimized Total Cost of Ownership (TCO)

Fleet managers understand that profitability hinges on maximizing uptime. This vehicle is constructed using highly durable, rigorously tested core assemblies that resist premature wear. The integration of a dual-circuit compressed air service brake and an engine exhaust valve auxiliary brake reduces the thermal load on brake components, extending their operational lifespan. These engineering choices drastically reduce unexpected downtime and lower long-term maintenance expenses, optimizing the comprehensive total cost of ownership.

Ideal Application Scenarios

This 6x4 tractor truck is engineered to excel across a variety of demanding, high-intensity environments:

  • Port Container Dispatch: The tight turning radius and immense low-end torque make it perfect for the continuous stop-and-go nature of moving heavy shipping containers within crowded port facilities.

  • Long-Haul Trunk Logistics: Equipped with a 400-liter fuel tank and a spacious HW76 sleeper cabin, the truck minimizes refueling stops and provides drivers with necessary rest, ensuring timely cross-country freight deliveries.

  • Heavy Construction Material Transport: With an approach angle of 19 degrees and a departure angle of 27 degrees, the chassis offers excellent ground clearance. This allows the truck to safely navigate the rutted, uneven surfaces typical of large-scale construction sites while hauling dense materials like steel, cement, or aggregate.

Global Shipping & Comprehensive Support

Procuring heavy machinery internationally requires absolute confidence in logistics and post-delivery service. We implement a rigorous, transoceanic anti-rust treatment for every truck, applying specialized protective wax coatings to shield the chassis and exposed metal components from the corrosive salt air encountered during sea transit. Our logistics team designs customized Ro-Ro (Roll-on/Roll-off) or flat rack shipping solutions, ensuring that your fleet additions arrive safely and efficiently within a targeted 25 to 35-day delivery window.

Upon arrival, our commitment continues through a globalized after-sales network. We guarantee the rapid provision of original factory spare parts, eliminating the frustration of extended wait times for critical components. Furthermore, our dedicated technical support framework provides comprehensive guidance for your mechanics, ensuring your vehicles remain in peak operational condition and your logistics operations proceed without interruption.
