What's the difference between semi trailer and full trailer?

In our country transportation industry, trailer is a kind of widely used vehicles. Trailer refers to a vehicle pulled by an automobile without its own power drive device, consisting of a car (truck or tractor, forklift) and a combination of one or more trailers.

Trailer is an important type of vehicle in highway transportation, which has the advantages of speed, mobility, flexibility and safety, and can conveniently realize section transportation. Trailers only together with tractors or other vehicles can form a complete means of transport.

Common trailer models are mainly full trailer and semi-trailer, so how to distinguish between these two vehicles? In fact, you just need to look at the way the vehicle is supported.

Full trailer refers to a trailer that can be supported independently. As the name implies, the load of the whole trailer is fully borne by itself, and the main car is only connected by hooks. The main car does not need to bear the load of the trailer, but only provides power to achieve traction and steering of the whole trailer.

Typical full trailer is generally composed of frame, cargo platform (top), traction bar (frame) (with hanging ring), steering device, suspension, braking system, signal system, etc., mainly used for dock, factory, port and other fields within the transportation.

The semi-trailer refers to the trailer that cannot be independently supported, that is to say, the load of the semi-trailer needs to be borne by the semi-trailer and the main car together. The front half of the semi-trailer rides on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the weight of the trailer.

Semi-trailer is the most commonly used trailer in domestic transportation, which can be subdivided into many types, such as flat plate type, gooseneck type, concave beam type and all kinds of special semi-trailer. Because of its flexible application and large bearing capacity, it is especially suitable for long-distance and high-grade highway transportation, and has become the most important means of transportation in road transport vehicles.

In fact, in addition to the above two categories, there is another type of trailer - the middle axle trailer. The structure of middle axle trailer is between full trailer and semi-trailer, its main weight is borne by the trailer, the main car bears a small part of the weight of the trailer, and the traction and steering are completed by the main car. General middle axle trailer is suitable for running on high - grade highway.

Semi-trailer, full trailer and mid-axle trailer, although different in structure, have their own advantages and disadvantages in different dimensions, and play a role in the areas they are good at. But no matter what kind of trailer model, if you want to improve the efficiency of logistics transportation, reduce logistics costs and ensure safe operation, you must choose a trailer axle with good quality and reliable performance.
