Performance & Engineering

At the heart of this HOWO dump truck lies the Weichai Power WD615.47 engine, a 6-cylinder, 9.7-liter turbocharged diesel powerplant that produces 440 horsepower and delivers maximum torque exceeding 2,500 Nm. This engine family has accumulated billions of operating hours across global mining and construction applications, establishing a reputation for exceptional durability and simplified maintenance requirements. The electronically controlled fuel injection system optimizes combustion efficiency across the entire power band, providing responsive performance under load while maintaining reasonable fuel consumption levels. Air intake filtration is positioned to minimize dust ingress in肮脏 operating environments, protecting internal components from abrasive particulate matter that prematurely degrades lesser powerplants.

Power is routed through a FAST 8-speed manual transmission with synchronized gear ratios optimized for heavy hauling applications. The transmission's robust gearset handles the engine's substantial torque output with margin to spare, while the single reverse gear provides adequate functionality for loading and positioning maneuvers. The clutch assembly features a heavy-duty pressure plate and friction disc combination designed to withstand the abuse characteristic of repeated starts on inclines under full load. Drive is distributed to all eight wheels through a proven transfer case and differential assembly that balances torque delivery between front and rear bogies, maximizing traction in low-grip conditions while preventing drivetrain shock loads.

The chassis architecture employs heavy-duty steel frame rails with optimized crossmember placement, providing the torsional rigidity required to handle concentrated loads from the cargo box and the dynamic stresses imposed during severe off-road operation. Suspension components utilize a combination of leaf springs and hydraulic dampers that absorb impact forces from uneven terrain while maintaining stable handling characteristics. The braking system, while lacking advanced electronic aids, provides substantial stopping power through large-diameter drums or discs at each wheel position, essential for controlling fully-loaded vehicles descending steep grades. The 12-tire configuration distributes contact pressure effectively, reducing ground pressure in sensitive areas while maximizing pulling force.

Key Advantages & Features

• 440HP Weichai Powerplant: The WD615.47 turbocharged diesel engine delivers class-leading horsepower output, providing exceptional acceleration and hill-climbing capability even when operating at maximum payload capacity. The engine's proven design ensures widespread parts availability and established service procedures at facilities worldwide.
• 31-40 Metric Ton Payload Rating: With a gross vehicle weight rating exceeding 30 tons, this dump truck accommodates substantial payload masses, reducing per-ton transport costs and improving overall fleet efficiency. The reinforced cargo box construction handles the demands of dense materials like aggregate, ore, and excavated earth.
• 8x4 Drivetrain Configuration: The eight-wheel drive system provides superior traction in muddy, rocky, or otherwise challenging terrain where conventional trucks struggle. The balanced weight distribution prevents bogging and improves stability on uneven ground surfaces common to mining and quarry operations.
• FAST 8-Speed Manual Transmission: The proven FAST gearbox offers precise gear selection and durable construction that withstands the demanding shift patterns typical of heavy hauling operations. Wide gear spread ratios enable efficient operation at both low speeds for technical sections and highway speeds during repositioning.
• 5,400mm Cargo Box Dimensions: The spacious cargo body measures 5.4 meters in length with 2.3-meter width and 1.5-meter side height, providing generous volume for high-capacity material transport. The box design facilitates rapid dumping through reliable hydraulic tipping mechanisms.
• Comprehensive Refurbishment: This used unit has undergone thorough inspection and restoration processes that address critical components, ensuring reliable operation and reduced immediate maintenance requirements compared to typical as-seen used equipment.
• 300-400L Fuel Capacity: Substantial fuel tank volume extends operating range between refueling stops, reducing downtime and improving productivity in remote operation sites where fuel availability may be limited.
• Proven HOWO Platform Support: The widespread popularity of HOWO vehicles ensures excellent parts availability, established dealer networks, and extensive operator knowledge, minimizing operational support challenges across diverse geographical locations.

Ideal Applications

• Open-Pit Mining Operations: The 8x4 drivetrain and high ground clearance enable effective navigation of uneven pit floors and ramp grades, while the 440HP powerplant handles the continuous pulling demands of loaded vehicles ascending steep exit routes. The substantial payload capacity maximizes tons moved per operating hour, directly improving mining economics.
• Quarrying and Aggregate Processing: Transporting crushed stone, sand, gravel, and similar materials from extraction points to processing facilities requires vehicles that tolerate continuous loading and dumping cycles. The reinforced cargo box construction resists impact damage from heavy aggregate materials while the hydraulic tipping system enables rapid discharge.
• Large-Scale Earthmoving Projects: Dam construction, highway building, and other major infrastructure projects generate significant spoil volumes requiring efficient transport to disposal or utilization areas. The combination of payload capacity and off-road capability allows continuous operation across undeveloped construction sites.
• Stripping and Overburden Removal: Removing waste material to access economic mineral deposits demands reliable heavy equipment that operates continuously in abrasive, dusty environments. The HOWO platform's proven durability and widespread parts support minimize operational interruptions in these time-sensitive operations.
• Heavy Construction Material Transport: Hauling bulk construction materials including fill dirt, clay, rock, and processed aggregates benefits from the vehicle's generous cargo volume and durable construction. Construction site access roads often lack paving, making the off-road capability essential for timely material delivery.
• Remote Infrastructure Development: Oil and gas field development, pipeline construction, and similar remote projects often lack established service infrastructure, making the excellent parts availability and established maintenance procedures of the HOWO platform particularly valuable for ensuring equipment availability.
