The tractor head is an important component of a heavy-duty truck, primarily used to tow semi-trailers or trailers, and is widely used in logistics, construction, mining, and other fields. Its core function is to provide power and traction capacity, and it is usually equipped with a high-horsepower diesel engine (such as 371HP-450HP) and a multi-axle drive system (such as 6×4 or 8×4).

• Drive Type

1.6×4 Drive: Commonly found in medium- and heavy-duty tractors, such as the HOWO 371HP model, suitable for long-distance hauls and difficult road conditions.

2.8×4 Drive: Higher load capacity (e.g., 50 tons), suitable for mining or heavy-duty cargo transport.

• Powertrain

1. Engine power typically ranges from 351-450HP, with emission standards covering Euro II to Euro IV.

2. Transmission types include manual (e.g., HW19710) and automatic (e.g., ZF8098).

• Additional Features

Some models are equipped with ABS, air suspension, or a hydraulic dump mechanism (e.g., tipper truck variants).
