A lot of people may ask what's the difference between a full trailer and a semi-trailer, a full trailer and a semi-trailer are just connected in a different way than the front trailer. The full trailer or semi-trailer also does not have its own power device, the full trailer is the front end of the trailer connected to the rear end of the tractor, the tractor only provides tension, not bear weight. A semi trailer is a trailer with the front half of the trailer attached to the towing saddle above the rear section of the trailer, and the bridge behind the trailer bears part of the trailer's weight. The most common semi-trailers are flatbed trailers and large container carrier trailers.

Full trailers can independent support, and semi trailers must rely on the front leg to stand, all full trailer loads borne by itself, connected to the tractor with peg, tractor don't need to bear the trailer load, it's only used to provide traction, semi-trailer is provided by the tractor, in addition to providing power,it needs to burden the trailer load.

There are many types of full trailers, whose basic frame, body and moving system are basically the same as those of freight trucks. The rail-plate carriage is generally made of thin steel plate. The longitudinal concave ribs are stamped on the rail-plate of the carriage, and the transverse welded ribs are used to increase the stiffness of the carriage and reduce the mass of the carriage. The floor plate of the carriage is generally made of wood and covered with thin steel plate, or of iron and wood mixed structure. The frame is usually made of 16MN steel plate, which is pressed into profiles and welded or welded. The longitudinal and crossbeam of the frame mostly adopt groove interface structure, and the two longitudinal beams are arranged with equal width before and after, so that the frame has better bending resistance performance.

The full trailer is generally composed of frame, body, traction device, steering device, suspension, walking system, braking system, signal system, etc.
