HOWO 6×4 371HP Heavy-Duty Tractor Truck For sale
Sinotruk HOWO 6×4 371HP Heavy-Duty tractor truck is equipped with a 371HP WD615 engine, 10-speed transmission, and HC16 rear axle. Its 6×4 drive & off-road tires make it ideal for construction transport and heavy-duty towing, offering reliable performance and high load capacity.
HOWO 6×4 371HP Heavy-Duty Tractor Truck For sale Description:
Designed to excel in both on-highway haulage and rugged off-road scenarios, the Sinotruk HOWO 6×4 371HP Heavy-Duty Tractor Truck stands as a robust solution for construction, mining, and heavy cargo transportation. At its core, this unit is powered by the WD615.47 6-cylinder in-line water-cooled engine, delivering 371 horsepower with Euro 2 emission compliance—striking a balance between power output and operational efficiency for long-haul or heavy-load tasks.
Paired with the HW19710 transmission (10 forward gears + 2 reverse gears, gear ratios ranging from 4.42 to 5.73), ensuring smooth gear shifts and optimized torque distribution across varying terrains. The chassis is reinforced with a New H9 front axle (drum brake system) and HC16 pressed rear axle (single reduction, differential lock housing + drum brakes), supporting a front axle load of 7,000 kg and rear axle load of 16,000 kg—enabling a gross vehicle weight of 25,000 kg, suitable for pairing with heavy-duty trailers (e.g., flatbeds, dump trailers) in construction or logistics fleets.
For off-road capability, the Heavy-Duty Tractor Truck features 12.00R20 steel wheels (with optional rim/tire sizes including 8.5-22.5, 11.00-20, etc.) wrapped in rugged off-road tires, complemented by its 6×4 drive configuration to tackle loose gravel, muddy job sites, or uneven terrain. The HW76 brand driver’s cab enhances operator comfort: it’s a full-floating air suspension cab (1 sleeper berth) with a 4-point mounting system, adjustable height/angle settings, and an air suspension seat—reducing fatigue during extended shifts.
Dimensionally, the unit measures 6800×2496×3230 mm (overall length/width/height) with a wheelbase of 3200+1350 mm and front/rear wheel tracks of 1830/1830 mm, ensuring stability during heavy towing. Performance highlights include a maximum driving speed of 102 km/h, minimum turning radius of 12.65 m, and 18.5° minimum ground clearance—blending on-road maneuverability with off-road durability.
Whether deployed for construction material haulage, mining site logistics, or long-distance heavy cargo transport, the HOWO 6×4 371HP Heavy-Duty Tractor Truck combines Sinotruk’s proven engineering, robust componentry, and operator-centric design to deliver consistent performance in demanding operational environments.
