Low Plate Semi-trailer

Mar 30, 2019

The low-slab semi-trailer has no hurdles in the vehicle parts and is widely used for medium and long-distance freight transportation. The series of semi-trailer frames are of the beam-type structure, and the longitudinal beams are of the straight live gooseneck type. The web height is from 400mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot peened, the beam is inserted into the stringer and welded. It consists of a series of dry plate springs and suspension bearings. It has a reasonable structure and strong rigidity and strength. 

It is used to support load cushioning. Low-profile semi-trailers are commonly used to transport heavy-duty vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machines, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) As with other heavy-duty cargoes, the lower the center of gravity, the better the stability and safety, and the greater the ability to transport ultra-high cargo and obstacles through the head. The low-profile semi-trailer structure and the low-profile semi-trailer usually use a concave beam (or well type) frame, and the front section of the frame is a gooseneck (the front of the gooseneck is connected to the traction saddle on the tractor, the gooseneck The rear end is connected to the semi-trailer frame), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including the wheel). 

When loading mechanical equipment on a low-profile 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 wheel, and then fixing the mechanical equipment to the semi-trailer. on. The low-profile semi-trailer walking structure uses high-strength international steel material, and the whole vehicle has light weight and guarantees its resistance to twisting, shock and bounce, and meets different road carrying capacity.
