When loading mechanical equipment on a low-bed semi-trailer, it is usually loaded from the rear end of the semi-trailer, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment on the semi-trailer. superior.
Low flat semi-trailer usually adopts concave beam type (or well type) frame, that is, the front section of the frame is a gooseneck (the traction pin of the front section of the gooseneck is connected to the traction saddle on the tractor, and the rear end of the gooseneck is connected to the semitrailer frame. connected), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels).

Features
1. The low flatbed semi-trailer series has flatbed, concave beam and tire exposed structure, and the longitudinal beam is straight or gooseneck. The frame is stepped, and the longitudinal beam section is I-shaped, which has the characteristics of high rigidity and high strength.
2. The main plane of the frame and platform is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large-scale equipment and steel.
3. It adopts three-axis balance type, two-axis balance type or rigid suspension, and a mass balance block is installed between the front and rear leaf springs, which can make the deflection of the front and rear leaf springs change in an equal amount, so that the front and rear axles are balanced.
4. The low-bed semi-trailer series products are suitable for the transportation of various kinds of mechanical equipment, large objects, highway construction equipment, large tanks, power station equipment and various steels. They are widely used, efficient and fast. The whole vehicle adopts advanced computer-aided design software, and the optimization design is flexible and diverse, and the frame bearing surface is designed according to user requirements to meet the transportation of various special goods.
