A full trailer is an independent load-bearing vehicle that relies on other vehicles to provide power for towing. Its load is entirely borne by itself, and it is only connected to the towing vehicle through a hook. The towing vehicle does not need to bear the load of the trailer, but only provides power to help the trailer overcome the friction resistance of the road.
Full trailers are mainly used for short-distance transportation of goods in docks, factories, ports and other areas. Due to its simple structure, it is usually composed of a frame, a body and a towing device. Full trailers play an important role in logistics transportation.
The opposite of a full trailer is a semi-trailer, which requires a tractor to provide a support point, and in addition to providing driving force, the tractor also needs to bear most of the trailer's load. This difference is similar to two people carrying a wooden board together, where the person in front is equivalent to the tractor and the person behind is equivalent to the semi-trailer.
