HOWO 375HP 6×4 Dump Truck

The truck uses a 375 HP Sinotruk diesel engine. Power is sent through a Sinotruk manual transmission to the two driven rear axles.

For a 6×4 dump truck, 375 HP provides a good working range for normal construction and material transport. The actual performance will naturally depend on the load, road conditions, driving habits and trailer or body configuration.

The manual transmission is also a familiar choice in many overseas markets. Local technicians are generally more accustomed to this type of drivetrain, which can make routine maintenance easier to arrange.

The 6×4 configuration means that both rear axles provide driving power. This is useful when the truck is loaded and has to start on an incline or travel over rough construction roads.

A 16-ton heavy-duty rear axle is used at the rear. The chassis also features a double-layer frame with an 8+5/300 specification, giving the truck a solid base for regular dump-truck work.

For used or stock vehicles, the frame should be inspected carefully. Areas around the cross members, suspension mounts and main frame rails can show signs of heavy loading or previous repairs.

The truck comes with a 5.6-meter ribbed dump body.

 

This type of body can be used for materials such as soil, sand, gravel and construction waste. The ribbed structure also gives the body additional support during normal loading and unloading operations.

 

 

One thing to keep in mind is that body volume and legal payload are not the same thing. A truck carrying wet soil, for example, can reach its weight limit much sooner than the same body filled with a lighter material.

 

 

The vehicle uses the HW76 cab and is finished in red.

The HW76 is a familiar Sinotruk cab design and is widely seen on HOWO heavy trucks. For export customers, familiarity can be useful because replacement parts and maintenance knowledge may already be available in the local market.

The cab specification can be checked and adjusted according to the final vehicle before shipment.

The truck uses a heavy-duty rear axle and a double-layer chassis frame. Combined with the 6×4 drivetrain, the setup is intended for regular loaded operation.

It is fitted with 12R22.5 tires. Before purchasing a stock or used truck, the tire tread, sidewalls and wear pattern should be checked. Uneven wear can sometimes point to problems with the suspension, steering or axle alignment.

The 300L fuel tank is suitable for regular construction and regional transportation. For longer routes, fuel consumption should be calculated according to the actual payload and road conditions rather than relying on the tank size alone.

The HOWO 375HP 6×4 Dump Truck is a better match for customers who spend most of their working time on construction sites, material yards, quarries and local transport routes.

It can handle common bulk materials such as sand, gravel, soil and construction waste, provided the load stays within the permitted limits.

For extremely heavy mining applications, buyers should compare axle ratings, frame dimensions, dump-body construction and local payload regulations before choosing a configuration. A standard construction dump truck and a dedicated mining truck are not designed for exactly the same working conditions.

If the truck is a stock or used vehicle, don't judge its condition from the cab and paint alone.

Start the engine from cold and listen for unusual noise. Check the transmission while shifting through the gears. The rear axle should be inspected for oil leaks, abnormal noise and signs of previous repair.

The dump-body hydraulic system should also be tested through a complete lifting and lowering cycle. Look at the hydraulic cylinder, hoses, pump and PTO connections for leakage.

The dump body itself deserves a close inspection. Check the floor and side panels for serious deformation, cracks and excessive welding. These areas can tell you quite a lot about how hard the truck has been used.
