What Stands Out in Daily Use

The main point of this truck is the combination of a 371 HP engine and 6×4 drivetrain. For a loaded trailer, having two driven rear axles can make a noticeable difference when leaving a muddy site or climbing a road with a heavy load.

The manual gearbox also keeps the driving system familiar for markets where manual trucks are still common. Drivers can choose a lower gear when climbing or carrying a heavy trailer instead of depending on automatic shifting.

The HW76 cab is a well-known HOWO cab layout, with the main controls kept within easy reach. For a truck that may spend many hours on the road, having a familiar and simple cab can be more useful than adding unnecessary equipment.

Chassis and Load Work

The 13R22.5 tires provide a relatively large contact area and are commonly used on heavy commercial vehicles. Tire choice should still be adjusted according to the local road surface and trailer weight.

The chassis uses a double-layer 8+5/300 frame. Together with the 16-ton rear axles, it is intended for work where the tractor and trailer regularly carry substantial weight.

With a 300L fuel tank, the truck is more suited to regular routes where refueling points are available along the way. Actual fuel range depends heavily on trailer weight, road conditions, driving speed and engine condition.

Where It Can Be Used

This HOWO tractor can be matched with different semi-trailers for cargo transportation. Common applications include general freight, machinery transport, construction material hauling and trailer-based logistics.

For buyers working mainly on paved highways, the truck can be used for long-distance cargo routes. The 6×4 configuration also gives it more flexibility when the route includes construction roads, gravel sections or moderate slopes.

Inspection Before Delivery

Before shipment, the truck is checked as a complete vehicle rather than only looking at the body condition.

The engine is started to check operation, smoke and possible leakage. The manual gearbox and clutch are tested, and the rear axles, driveshaft and frame are inspected for visible problems.

We also check the 13R22.5 tires, braking system, lights, electrical equipment and fuel system. For stock vehicles, buyers can request photos or running videos before shipment.

Packing & Delivery

The shipping method depends on the destination and the number of trucks ordered. Ro-Ro and bulk vessel shipping are common options for complete tractor trucks.

Before loading, the vehicle is cleaned and prepared for sea transportation. Loose or vulnerable parts are secured, and the truck is fixed properly during loading to reduce movement during the voyage.
