Howo 371 Tractor Truck

We have not only the standard configuration but also the advanced configuration, which can be modified according to the customer’s needs

Engine: Equipped with an engine independently developed by Sinotruk. Displacement is approximately 9.726 liters or 7 liters, delivering a maximum output of 271 kW (approximately 371 horsepower). It generates a massive torque of around 1800 N·m within the low-speed range of 1100-1400 rpm. This low-rpm, high-torque characteristic ensures robust performance during acceleration, hill climbing, and overtaking, while also facilitating lower engine speeds for improved fuel efficiency.
Transmission: Paired with Sinotruk’s 9-speed, 10-speed, or 12-speed manual transmission featuring dual H-pattern shifters, offering relatively light gear changes. The multi-speed design allows drivers to precisely select gears based on speed and road conditions, ensuring the engine consistently operates within its optimal fuel-efficient range.
Clutch: Features a large-diameter φ430mm single-plate dry clutch, delivering high torque transmission and excellent durability.

Cab: Features a high-roof double-berth cab with ample interior headroom, allowing the driver to stand upright. The four-point suspension design effectively filters road vibrations.
Bunk: Equipped with upper and lower bunk beds. The lower bunk typically exceeds 800mm in width, providing drivers with a comfortable resting environment.
Interior and Features: Standard equipment includes mechanically damped seats, a multifunction steering wheel, analog or combined analog/digital instrument cluster, manual air conditioning, and a radio.

Drive Configuration: 6×4, featuring front-wheel steering and rear dual-axle drive.
Frame: Constructed from high-strength steel with a double-layer design and a flange height exceeding 300mm. Exceptional bending and torsional rigidity ensures body integrity under severe road conditions.
Front Axle: Standard I-beam front axle with a typical permissible axle load of 7 tons.
Rear Axle: Equipped with Sinotruk’s classic STR dual rear axle (e.g., STR 16-ton class), offering a wide range of gear ratios (common options include 4.11, 4.42, 4.8, etc.).Users can select the appropriate gear ratio based on primary operating terrain (plains, mountains) to achieve optimal balance between fuel efficiency and power delivery.
