When customers compare used heavy dump trucks, the question is often simple: should they choose a 6×4 or an 8×4? The answer depends on the cargo body, required working volume and the conditions in which the truck will operate.

The HOWO HW76 8×4 dump truck in the supplied specification uses a WD615.47 engine with 371 HP and a 10-liter displacement. The truck is fitted with a HOWO HW76 cab with a new front cover, single sleeper and metal bumper. Its gearbox is listed as a reconditioned 19710+HW50 unit, while the AC16 drive axle with a 5.45 gear ratio is also listed as reconditioned. fileciteturn1file2L5-L16

One of the clearest differences between the 8×4 and 6×4 dump truck configurations is the cargo body. The supplied 8×4 configuration lists a cargo box size of 8500×2300×1500 mm. The bottom plate is 10 mm thick and the side panels are 8 mm thick. The listed rated cargo volume is 25 m³. fileciteturn1file2L17-L23

By comparison, the supplied HOWO 6×4 dump truck has a 5400×2300×1500 mm cargo box, with an 8 mm bottom plate and 6 mm side panels. The listed rated cargo volume is 20 m³. fileciteturn1file1L17-L22

This means the 8×4 dump truck provides a larger cargo body and a higher listed cargo volume in the supplied specifications. For customers whose business requires moving larger quantities of material, that difference may be an important factor.

The two dump trucks also share several major specifications. Both are based on the HOWO HW76 platform and use the WD615.47 371 HP, 10-liter engine. Both use the AC16 drive axle with a 5.45 gear ratio, and both list new front axles, new 12.00R20 tires and new ZF8118 steering gear in the supplied configurations. fileciteturn1file1L5-L15 fileciteturn1file2L5-L16

So, which one should a buyer choose?

Choose the HOWO 6×4 dump truck when you prefer a more compact cargo body and the 20 m³ listed cargo volume matches your daily transportation requirements. Its smaller cargo body may be easier to match with certain project conditions and operating requirements.

Choose the HOWO 8×4 dump truck when your priority is a larger cargo body and the higher listed 25 m³ cargo volume is more suitable for your business. Its supplied cargo body is longer, and both the bottom and side panel thicknesses are greater than those listed for the 6×4 dump truck. fileciteturn1file1L17-L21 fileciteturn1file2L18-L22

For mining, construction and other heavy-duty material transportation scenarios, customers should evaluate not only cargo volume but also road conditions, loading requirements, operating cycles and local regulations. The vehicle that provides the largest cargo body is not automatically the best choice for every operation.

In the end, the 6×4 and 8×4 HOWO dump trucks are designed for different priorities. The 6×4 offers a more compact configuration with a listed 20 m³ cargo volume, while the 8×4 provides a larger 25 m³ cargo volume and larger cargo body dimensions in the supplied specifications.

For international buyers, the most practical approach is to start with the job requirement, then compare the truck configuration against that requirement. With clear information about cargo body size, vehicle configuration and component condition, customers can select the HOWO dump truck that better matches their business.
