The HOWO 4×2 tractor truck is a flagship model from Sinotruk, one of China’s earliest and most influential heavy-duty truck manufacturers. Since the launch of the HOWO series in the early 2000s, Sinotruk has continuously refined its designs to meet international transport needs. The 4×2 configuration, meaning one drive axle and one steering axle, was introduced to serve operators requiring reliable long-distance haulage without the extra weight of additional axles. Over two decades of production, the HOWO brand has become synonymous with affordability, durability, and accessible service networks, especially for developing regions where cost-effective heavy trucks are in demand.
This tractor truck offers two main power options: 371 horsepower and 375 horsepower, both derived from advanced Euro II/III-compliant diesel engines. The engine is coupled with a robust manual transmission and reinforced drive axle to handle heavy loads efficiently. Standard parameters include a gross combination weight of around 40–50 tons, a spacious sleeper cab, air braking systems, and modern dashboard electronics. Sinotruk applies CAD-based engineering and robotic welding in its assembly lines, improving chassis precision and cab safety. Paint and anti-corrosion treatments meet international standards, extending the truck’s lifecycle even under harsh climates. Strict quality inspections at each stage ensure consistency before shipment.
In Africa, the HOWO 4×2 tractor head has become a common sight at ports, mines, and logistics corridors. Its balance of power and fuel economy suits regional freight routes where road conditions vary widely. The availability of 371 hp and 375 hp gives fleet owners flexibility between cost and performance. Sinotruk has also developed local spare-parts channels and training programs with dealers in countries such as Nigeria, Kenya, and Tanzania, reducing downtime and maintenance costs. Combined with competitive pricing and proven reliability, the HOWO 4×2 tractor truck continues to strengthen its position as a preferred heavy-duty transport solution on the continent.
