The cab can be hydraulically tilted forward 70° for easy maintenance of the engine and chassis structure. The HW70 cab is also available as an option to suit different engineering tasks.

Left-hand or right-hand drive configurations are available to meet the road regulations of different countries.

Heavy-duty Chassis Platform – Born for High-Load Conditions

The HOWO 8×4 dump truck adopts a four-axle, eight-wheel drive layout. Its dimensions are 10310 × 2500 × 3400 mm, with a wheelbase of 1800+3500+1350 mm. The vehicle's stable and wide stance is suitable for high-load, high-speed driving and complex construction site conditions.

● Payload capacity up to 45,000 kg, suitable for transporting ore, sand, gravel, and large-scale earthwork.

● Front axle load capacity: 2 × 9,000 kg

● Rear axle load capacity: 2 × 16,000 kg

The robust structural design ensures chassis stability and prevents deformation under full-load impact, frequent unloading, and uneven road conditions. The rational front and rear axle layout maintains good balance during loading, climbing, emergency braking, and cornering.

371 hp Sinotruk Engine – A Powerful Core for Continuous Output

The powertrain features a Sinotruk WD615.47 inline 6-cylinder diesel engine, employing:

• 4-stroke direct injection system

• Water-cooled structure

• Turbocharging + intercooling technology

• Euro II emission standard

The engine delivers a maximum output of 371 HP, providing ample power reserves. It provides continuous torque and acceleration even under full-load starts, on inclines, and in rough working environments, helping the vehicle maintain stable transportation efficiency.

Mature and Reliable Transmission System – Adaptable to Complex Working Intensities

• The vehicle uses an HW19710 manual transmission, providing 10 forward gears + 2 reverse gears. The wide gear ratio distribution and stronger low-speed torque make it suitable for narrow construction sites, heavy-load low-speed crawling, and frequent gear shifting in loading areas.

• Equipped with a 430 mm reinforced diaphragm clutch, featuring smooth operation, wear resistance, and long service life, maintaining a low failure rate in environments with frequent gear shifts.

• The steering system uses a ZF 8118 hydraulic power steering gear, offering high-precision steering and light handling, allowing the driver to easily control the vehicle even under heavy loads.

Engineering-Grade Braking System and Safety Structure Design

HOWO Dump Truck Configuration:

Dual-circuit compressed air service brake
Spring energy parking/emergency braking (applies to the rear axle)
Engine exhaust-assisted braking (enhances downhill stability)
The braking system offers fast response and strong braking force, ensuring the vehicle can be safely stopped even under heavy loads.

Professional Self-Unloading Device + HYVA Front-Mounted Lifting Hydraulic System

A: The 8×4 drive mode offers good traction and stability. Optional features such as heavy-duty tires and differential locks improve its ability to traverse soft surfaces and gravel roads.

Q: Will the high lifting frequency of the dump truck affect the lifespan of the hydraulic system?

A: The HOWO dump truck structure supports high-frequency operation, and the hydraulic system is designed for wear resistance and high pressure resistance. Timely maintenance can significantly extend the service life of the hydraulic cylinders and oil circuits.

Q: Does the HOWO 8×4 dump truck support customized cargo boxes?

A: Yes. Different cargo box structures can be selected according to the transported materials, such as standard square, U-shaped, wear-resistant steel, and lightweight designs, to improve loading efficiency and reduce wear.

Q: How is the vehicle's fuel consumption?

A: Fuel consumption varies depending on load, road conditions, and driving habits. HOWO models typically maintain good fuel economy under heavy load conditions. Fuel consumption can be optimized by selecting different rear axle ratios.

Q: How often is maintenance required under normal use?

A: Generally, the routine maintenance interval for the engine, transmission, and chassis is between 5,000 and 10,000 km. For harsh environments such as mining areas and high-dust environments, it is recommended to shorten the maintenance interval to improve reliability.
