The Difference Between Heavy-duty Trucks And Tractors

The difference between heavy-duty trucks and tractors is mainly reflected in the following aspects:
Design and transmission mode: The engine design and transmission mode of heavy-duty trucks are different from those of tractors. Heavy trucks usually adopt a multi axle design with relatively low power, while tractors have a large torque and can tow multiple vehicles, resulting in a large transportation volume.
Loading method: Heavy trucks need to carry cargo, usually with a truck body, and are a whole. And a tractor is a type of freight car, characterized by a tool traction connection between the front of the car and the car body. The front of the car can detach from the original car body to pull other car bodies, and the car body can also detach from the original car body to be pulled by other car bodies.
Frame and axle: Tractors and heavy-duty trucks also have different configurations in the frame and axle. Heavy vehicles typically use a double decker frame and wheel reduction axle, while semi-trailers typically use a single decker frame and a single reduction axle.
Towing method: The definition of a tractor is to tow a semi trailer or fully trailer powered front end, while a heavy-duty truck is usually a single unit cargo truck, characterized by the front end and cargo box being integrated, both mounted on a single beam.
In summary, a tractor is a special type of heavy-duty truck, and their main differences lie in the traction method, cargo loading method, and vehicle structural configuration. The front of the tractor and the cargo box are separated and connected by a towing disc, while the front of the heavy-duty truck and the cargo box are integrated.
