The working principle of a semi-trailer mainly includes its structural design and working mechanism. A semi-trailer is a heavy-duty transportation vehicle, with its axle placed behind the vehicle's center of gravity and connected to the tractor through a towing pin, forming a semi-trailer train. The design of a semi-trailer makes it unable to support independently and relies on the joint action of the front legs and the towing vehicle to maintain balance.
Structure design
A semi-trailer typically consists of a base plate, vertical plates, and horizontal plates. The upper surface of the bottom plate is fixedly connected to the vertical plate, and the upper surface of the vertical plate is further fixedly connected to the horizontal plate. There is a square groove on the vertical plate, and the sliding seat is connected to the sliding seat through the square groove. One side of the sliding seat is fixedly connected to the first mounting bracket, and the upper surface of the horizontal plate is fixedly connected to the second mounting bracket. This design allows the boxes to be conveniently placed through guide plates and automatically removed from the hopper by the device, while also performing automatic stacking, thus completing the unloading process with ease and speed.
Working mechanism
The front part of the semi-trailer overlaps with the rear saddle of the tractor, sharing some of the weight through the tractor's rear axle. Semi trailers have a large loading capacity and are suitable for long-distance and high-grade highway transportation. There are various types of trailers, including flatbed, gooseneck, recessed beam, and various specialized semi trailers, which are widely suitable for various transportation needs.
Application scenarios
Semi trailers play a crucial role in the logistics industry, with their excellent cargo transportation capabilities, efficiently and safely transporting various types of goods such as coal, steel, wood, fruits, vegetables, etc. Its high transportation efficiency not only saves time and costs, but also greatly improves the safety of goods.
