[0002] A semi-trailer is a means of transport, mainly used to transport various items on the road. It is an indispensable part of the automobile transportation industry. The main feature of a semi-trailer is that its axle is placed at the back of the vehicle's center of gravity, and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. It is usually connected to the semi-trailer head through a traction pin and is towed by the main vehicle. There are many types of semi-trailers, such as flatbed semi-trailers, box-type semi-trailers, and warehouse-type semi-trailers. Flatbed semi-trailers are mainly used to transport large machinery and equipment, steel and other items; box-type semi-trailers are used for long-distance transportation of light goods.
