The HoWo T7H, powered by a German MAN engine (353 kW/480 hp) and equipped with a reliable air braking system, is purpose-built for heavy-load transport at 70-ton maximum capacity. As high-tech features ensure efficiency, operational safety demands serious protocol adherence. Next, we will use it as an example to tell you the precautions for driving a dump truck.
I. Pre-Drive Preparations
1.Detailed Vehicle Inspection
Engine and Fluids: Monitor levels of coolant, oil, and diesel fuel for optimal performance. The MAN engine’s horsepower demand requires proper lubrication and cooling, especially under heavy loads.
Braking System: Test the responsiveness of air brakes and inspect air compressors and storage tanks for leaks. Proper braking is essential in the transportation of the T7H’s 70-ton maximum load capacity.
Tires and Cargo Security: Keep tire pressure and tread depth in check. Load cargo evenly across the 38 m³ cargo box and strap or secure with anti-slip mats to prevent movement.
2.Safety Equipment
Carry essential tools, a fire extinguisher, and reflective warning signs. The truck’s large size (11,000 × 2,550 × 3,500 mm) necessitates increased visibility at night.
II. On-Road Best Practices
1.Speed and Distance Management
Despite its maximum speed of 80 km/h, travel at a moderate speed (60–70 km/h) when carrying a load. Smooth transmission is ensured by the heavy-duty transmission, but hard acceleration or braking can stress the rear axle and increase accident risks. Maintain a safety gap of 150–200 meters to provide extra braking distance.
2.Blind Spot Awareness
The T7H’s size creates extensive blind areas. Employ side mirrors responsibly and install blind-spot cameras if available. When turning, use a wide radius to minimize the “inner wheel difference” effect, particularly in city driving.
3.Braking Strategy
Employ the engine brake on severe downhill grades to keep the air braking system to an absolute minimum. Avoid prolonged pressure on the brake pedal; make controlled, intermittent braking to prevent overheating.

III. Handling Specialized Scenarios
1.Mountainous Terrain
Downshift early using the heavy-duty gearbox to use engine braking. The MAN engine’s high torque output gives stability, but rough handling can be stressful for the front axle.
2.Adverse Weather Conditions
In rain or snow, reduce speed by 30–50% and install tire chains.
3.Urban Navigation
The width and height of the truck require attention while passing low bridges or narrow lanes—preplan routes to avoid restricted roads and follow local height/width regulations.
IV. Post-Drive Maintenance
Engine Maintenance: Oil the engine every 15,000 km and replace air filters from time to time to maintain the MAN engine at its best performance.
Brake System Maintenance: Drain daily the air tank moisture to prevent valve freezing. Inspect brake pads for wear, especially after prolonged runs.
Cargo Box Maintenance: Inspect 12 mm (base) and 10 mm (side) steel plates for damage or rust. Clean gently after carrying abrasive or corrosive material.
Conclusion
HoWo T7H delivers exceptionally well under heavy-hauling roles but demands a little respect for what it can do. With prudent planning, disciplined driving, and good maintenance, security and performance will be optimized. Always adhere to local authorities’ regulations governing load allowances (70 tons) and truck permits. Drive smart, drive safe!
