Low flat semitrailer
The low-flat semi-trailer has no railings on the vehicle and is widely used. The skeleton container semi-trailer direct selling is mainly used for medium and long-distance freight transportation. The semi-trailer frame is a beam through structure, and the longitudinal beam adopts a straight type live gooseneck style. The web height ranges from 400 mm to 550 mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot peening, and the cross beam is penetrated into the longitudinal beam and welded as a whole. Series dry plate spring and suspension bearing are composed of reasonable structure, strong rigidity and strength, which are used to support load buffer. Low-level semi-trailers are usually used to transport heavy trucks (such as tractors, buses, special vehicles, etc.), railway vehicles, mining machinery forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-duty goods. The lower the center of gravity, the better the stability and safety. The ability to transport super high goods and head overhead obstacles is stronger. Low-flat semi-trailer structure and load low-flat semi-trailer usually use concave beam (or shaft) frame, both the front frame for gooseneck (gooseneck front traction pin and tractor saddle connected, gooseneck rear end and semi-trailer frame connected), the middle section for the freight platform (the lowest part of the frame), the rear end for the wheel frame (including wheels). ). When loading mechanical equipment on low-flat semi-trailer, it usually loads mechanical equipment from the rear end of the semi-trailer, that is, moving the mechanical equipment from the rear wheel frame or removing the wheel, and then fixing the mechanical equipment on the semi-trailer. The traveling structure of the low-flat semi-trailer uses high-strength international steel with light dead weight, and ensures its anti-twist, anti-seismic, anti-bump ability, and meets different road surface bearing capacity.
