Executive Summary

The SINOTRUK HOWO 6x4 heavy-duty dump truck represents a proven solution for mining, quarrying, and large-scale construction operations requiring exceptional payload capacity and uncompromising durability. This used commercial vehicle has been engineered to excel in the most demanding off-highway environments, featuring a rugged steel cargo body measuring 6500×2350×1500mm that enables efficient transportation of aggregates, minerals, overburden materials, and construction debris. The vehicle's 6×4 drive configuration delivers superior traction on unpaved surfaces, while the powerful WEICHAI diesel powerplant ensures reliable performance under heavy loads and challenging terrain conditions.

As mining operations and infrastructure development projects continue to expand globally, the demand for heavy-duty tipper trucks capable of delivering high productivity rates has intensified. The HOWO series has established itself as a benchmark in the 21-30 ton payload class, offering operators an optimal balance between initial acquisition cost and total cost of ownership. This particular unit combines the proven reliability of SINOTRUK's drivetrain technology with a robust suspension system featuring air-suspended driver's seating, ensuring operator comfort during extended shifts in demanding operational environments.

The vehicle's Euro 2 emission compliance makes it particularly suitable for markets and applications where modern emissions standards are not yet mandated, while still delivering the environmental performance required for responsible industrial operations. With its manual 12-speed transmission, drivers can precisely match gear ratios to varying load conditions and gradient profiles, maximizing fuel efficiency and drivetrain longevity across diverse operating scenarios.

Performance & Engineering

The WEICHAI 6-cylinder diesel engine powering this HOWO dump truck represents China's leading heavy-duty powerplant technology, delivering between 351 and 450 horsepower with maximum torque output ranging from 1500 to 2000 Newton-meters. This engine displacement exceeding 8 liters provides the substantial low-end torque characteristics essential for heavy-duty dump truck applications, enabling efficient loaded starts on steep inclines and maintaining consistent power delivery throughout the operating RPM range. The proven Euro 2 emissions architecture ensures reliable operation with straightforward maintenance requirements, reducing unplanned downtime and supporting predictable maintenance scheduling.

The SINOTRUK 12-speed manual transmission paired with this powerplant offers drivers exceptional control over power delivery, with carefully spaced gear ratios optimized for loaded and empty travel cycles. The transmission features synchronized gear engagement for smooth shifts, while the two reverse gears provide adequate maneuvering capability for loading and dumping operations in confined spaces. This transmission configuration has been extensively validated in global mining operations, demonstrating remarkable durability under continuous heavy-duty operation cycles.

The vehicle's heavy-duty chassis and suspension system have been specifically engineered for the abusive operating conditions typical of mining and quarrying environments. The gross vehicle weight rating of 15-20 metric tons, combined with the substantial 21-30 ton payload capacity, results in a robust frame construction capable of withstanding the dynamic stresses of off-road dump operations. The air-suspended driver's seat significantly reduces whole-body vibration exposure, contributing to reduced operator fatigue and improved safety outcomes during extended operational periods. Ten heavy-duty tires mounted on dual rear axles distribute loads effectively while providing the traction necessary for confident operation on soft, uneven, or muddy surfaces.
