SINOTRUK HOWO 371HP 400HP 6x4 Heavy Duty Tipper Truck for Sand Transport

The SINOTRUK HOWO 6x4 Heavy Duty Tipper Truck is available in both 371HP and 400HP engine configurations, providing flexibility for different payload requirements and operating conditions. This model is specifically optimized for sand, gravel, and aggregate transport operations. The 371HP variant uses the proven WD615.47 engine, while the 400HP variant features the upgraded WD615.69 engine with 11-liter displacement producing 400 HP at 2200 rpm and 1750 Nm of torque. The additional power of the 400HP model is particularly beneficial for operations involving steep gradients, high-altitude sites, or heavier payloads. For sand and aggregate transport, the cargo box features a 20mm thick high-strength steel body with a large 25-30 cubic meter capacity. The box includes a front extension board adding 3 cubic meters of additional volume for lightweight materials like sand. The tailgate is equipped with a hydraulic locking mechanism for secure transport. The chassis features a reinforced frame with 10mm thick main beams and cross-members designed for continuous heavy-load operation. The suspension system uses 12-layer leaf springs on the rear axle with reinforced spring pins and brackets. All pivot points use maintenance-free bushings for reduced downtime. Both variants share the same reliable HW19710 transmission, HC16 rear axle, and WABCO braking system. The fuel-efficient powertrain delivers low operating costs per ton-kilometer, making this truck a profitable choice for material transport businesses.
