Understanding HOWO dump truck capacity specifications is essential for selecting the right vehicle for your construction or mining operations. This comprehensive guide covers the key capacity metrics for HOWO A7, 371, and other SINOTRUK dump truck models.
The HOWO A7 dump truck, available in 6x4 and 8x4 configurations, offers a payload capacity ranging from 20 to 30 tons. The cargo body volume measures approximately 18-22 cubic meters for the 6x4 variant and 22-28 cubic meters for the 8x4 configuration. The A7 model is powered by SINOTRUK's advanced engine series with output from 336HP to 420HP, providing excellent power-to-weight ratio for loaded operations.
The HOWO 371 dump truck, named after its 371 horsepower engine rating, is a popular choice for medium to heavy-duty applications. With a 6x4 drive configuration, it offers a payload capacity of 20-25 tons and a cargo body volume of 16-20 cubic meters. The 371HP engine delivers strong low-end torque, making it well-suited for operation in hilly terrain and soft ground conditions.
Fuel consumption is a critical consideration for dump truck operations. The HOWO dump truck typically achieves fuel consumption rates of 25-35 liters per 100 kilometers under loaded conditions, depending on terrain, load weight, and driving style. The fuel tank capacity ranges from 300 to 400 liters, providing a theoretical range of 800-1,200 kilometers between refueling stops.
The load capacity specifications include the Gross Vehicle Weight (GVW) rating, which is 25 tons for 6x4 models and 31 tons for 8x4 configurations. The chassis frame is designed with a safety factor exceeding the rated capacity, ensuring reliable operation even under occasional overload conditions. The suspension system, featuring multi-leaf springs with auxiliary springs, provides stable load support and good ride quality.
When selecting a HOWO dump truck based on capacity, consider the specific gravity of the material being transported, the haul road conditions, and any regulatory weight limits in your operating area. The SINOTRUK technical team can assist with selecting the optimal configuration for your specific requirements.
