In our transportation industry, the trailer is a widely used vehicle. Trailer refers to a vehicle pulled by a car, without its own power drive device, by a car (truck or tractor, forklift) and a combination of one or more trailers.
Trailer is an essential type of highway transportation, which has the advantages of speed, mobility, flexibility, safety and so on, and can conveniently realize section transportation. A trailer can only form a complete vehicle together with a tractor or other vehicle.
Common trailer models are mainly full trailer and semitrailer, so how to distinguish between these two kinds of vehicles? According to Semi Trailer Manufacturers, only the supporting mode of the vehicle is needed.
Full trailer refers to a trailer that can be supported independently. As the name implies, the load of the full trailer is entirely borne by itself, and it is connected to the main vehicle only by hooks. The main vehicle does not need to bear the load of the trailer, but only provides power to realize the traction and steering of the full trailer.
The typical full trailer is typically composed of frame, cargo platform (top), traction rod (frame) (with hanging ring), steering device, suspension, braking system, signal system and so on. It is mainly used for transportation in the dock, factory, port and other fields.
Semi-trailer refers to a trailer that cannot be supported independently, that is to say, the load of the semi-trailer needs to be borne by the semi-trailer and the main vehicle together. The front half of the semi-trailer rests on the traction saddle above the rear segment of the tractor, and the bridge behind the tractor bears part of the weight of the trailer.
The semi trailer is the most commonly used in the domestic transportation of a trailer, can be subdivided into numerous kinds, such as flat type, gooseneck type, concave beam type and all kinds of special semi trailer, because of its flexible application, carrying capacity, especially suitable for long-distance, high-grade highway transport, has become the most influential means of transport in the road transport vehicle.
In fact, in addition to the above two categories, there is another type of trailer - the mid-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 minor part of the weight of the trailer, traction and steering are completed by the main car. Normally, a middle axle trailer is suitable for running on a high grade highway.
Although the semi-trailer, full trailer and mid-axle trailer are different in structure, they have their own advantages and disadvantages in different dimensions and play a role in the field they are excellent at. But no matter what kind of trailer model, want to improve logistics transportation efficiency, reduce logistics costs, ensure safe operation, must choose a quality pass, reliable performance of the axle.
