Distinguishing points of full trailer and semi-trailer: different traction modes
First of all, we have to clarify two concepts: what is a tractor? What is a trailer? The front with driving capacity is called a tractor, and the rear without driving capacity is called a trailer. The trailer is dragged by the tractor. The full trailer and semi-trailer are distinguished based on the different connection modes of the front tractor.
The most obvious difference between full hanging and semi hanging is that the full hanging can stand stably independently, while the semi hanging must rely on the front outrigger to stand.

The full trailer is literally well understood. The load of the whole vehicle is fully borne by the trailer itself, which is only connected with the main vehicle by hook. The main vehicle does not need to bear the trailer load, but only provides power to realize the traction and steering of the whole trailer. A typical full trailer is generally composed of frame, pallet (top mounted), drawbar (frame) (with hanging ring), steering device, suspension, wheels, braking system, signal system, etc. At present, full trailers are mainly used for transportation in docks, factories, ports and other sites.

The most popular period of all Trailer in China is the 1970s-1990s. At that time, the output of cars was small, the speed was very low, the roads were underdeveloped, and there were no special requirements for tractors; With the advantages of convenient coupling and low manufacturing cost, full trailers are widely used under the comprehensive influence of road and technical conditions. There are many trailer manufacturers in China. At present, many refitting factories start from the production of trailers. However, with the development of China's automobile industry and the popularization of expressways, the safety problems of traditional full trailers such as braking tail flick and poor high-speed straight-line driving performance are exposed. Therefore, the use of full trailers is limited in China
