Low flatbed semi trailers have no railings in their vehicle parts and are widely used, mainly for medium to long-distance freight transportation. The frame of the series semi-trailer is a beam through structure, and the longitudinal beam adopts a flat and movable gooseneck type. The height of the web plate ranges from 400mm to 550mm, and the longitudinal beam is automatically submerged arc welded. The frame is shot peened, and the crossbeam is penetrated into the longitudinal beam and welded as a whole. The series type dry plate spring and suspension support are composed of a reasonable structure, with strong rigidity and strength, and are used to support load-bearing and slow impact. Low flatbed semi-trailers are usually used to transport heavy vehicles (such as tractors, buses, specialized vehicles, etc.), rail vehicles, mining and forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.), and other heavy goods. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high goods and pass through overhead obstacles. The structure and loading of low flat semi trailers usually adopt a concave beam (or well shaped) frame, with the front section of the frame being a gooseneck (the traction pin of the gooseneck front section is connected to the traction saddle on the tractor, and the rear end of the gooseneck is connected to the semi trailer frame), the middle section being a cargo platform (the lowest part of the frame), and the rear end being a wheel frame (including wheels). When loading mechanical equipment onto a low flatbed semi-trailer, it is usually done from the rear end of the semi-trailer by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment onto the semi-trailer. The walking structure of the low flat plate semi trailer uses high-strength international steel materials, with a light weight and ensuring its ability to resist twisting, earthquake resistance, bumps, and meet different road bearing capacities.
