A trailer is a vehicle which is towed by a motor vehicle and which does not have a drive of its own, and is usually in the form of a multi-axle trailer for transporting a domestic or small freight vehicle. Conventional truck trailers are unable to rotate because the lower deck platform, thus setting the axle position to a low angle incline or flush the lower deck platform with the upper portion of the axle.

When the position of the axle is set to be a small-angle inclined plane, if the chassis of the transported automobile is high and the head of the automobile is short, such as in the case of a bread car, the wheels of the automobile are required to be as close to the axle of the trailer as possible, but the top of the transported automobile will be raised; when the lower platform is level with the upper part of the axle, the whole lower platform is heightened, and the top of the automobile is lifted while the gravity center of the whole trailer is also lifted.

For the safety of transportation, the country requires that the overall length and height of the trailer after loading the vehicle be limited. In order to meet the requirement of the overall height of the overall trailer, the roof height of the lower layer loading vehicle needs to be controlled, namely, the wheels of the lower layer loading vehicle cannot be positioned on the inclined plane of the axle position, or a single-layer transportation mode is adopted.

If the scheme that the wheels of the lower-layer vehicle cannot be located on the inclined plane of the axle position is adopted, after the vehicles (the vehicle types with longer vehicle heads and vehicle tails) of some vehicle types are loaded, the vehicle bodies of the vehicles will extend out of the lower-layer platform of the trailer (because the space of the axle position is not utilized), so that the limitation on the overall vehicle length of the trailer is exceeded, the lower-layer platform can only transport the vehicle types with shorter vehicle lengths, and the transportation limitation is large. If the single-layer transportation mode is adopted, the transportation cost of the single vehicle is obviously increased.
