Fuel Efficiency Analysis
Fuel efficiency is optimized through calibrated integration of the Weichai WD615 engine and HW19710 transmission, enabling extended gear ratios and reduced engine RPM during cruising. Under mixed operation (40% highway, 60% on/off-site hauling):
- Average Fuel Consumption: 32–36 L/100 km at 45-ton GVW
- Best-in-Class Efficiency Achieved: 28 L/100 km (highway cruise, 8th–10th gear, 1,600 rpm)
- Engine ECU Tuning: Load-adaptive fuel mapping with over-fuel protection
The use of low-rolling-resistance radial tires (12.00R20) contributes to a 4–6% improvement in fuel economy versus bias-ply equivalents. Additionally, optimized rear axle ratio (HC16 @ 5.45) balances tractive effort and cruise efficiency.
Load Capacity & Hitch Plate Performance
The trailer hitch plate is designed to support high-moment loading during dump cycles and uneven terrain traversal. Key load performance metrics:
- Max Permissible Trailer Mass (Braked): 40,000 kg
