Low bed trailer: the "hot commodity" in the transportation industry

Recently, if you pay attention, you will find that there are more and more Low bed trailers on the road. What is going on? Why are Low bed trailers suddenly so popular? Today, let's talk about this topic and see what the charm of Low bed trailers is.

Low bed trailers have no railings on the vehicle and are widely used, mainly for medium and long-distance freight transportation. The frame of the series semi-trailer is a through-beam structure, and the longitudinal beam adopts a straight live gooseneck structure. The web height ranges from 400mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot peened, and the crossbeam penetrates the longitudinal beam and is welded as a whole. It is composed of a series of dry leaf springs and suspension supports, with a reasonable structure, strong rigidity and strength, and is used to support load buffering.

Low bed trailers are usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-loaded goods. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport oversized goods and pass overhead obstacles.

Low bed trailer structure and loading

Low bed trailers usually use a concave beam (or well-type) frame, that is, the front section of the frame is a gooseneck (the traction pin at 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 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 wheels).

When loading mechanical equipment on a Low bed trailer, it is usually loaded from the rear end of the semi-trailer, that is, the mechanical equipment is moved from the rear wheel frame or the wheels are removed, and then the mechanical equipment is fixed to the semi-trailer.

The walking structure of the Low bed trailer is made of high-strength international steel. The vehicle has a light weight and is guaranteed to be resistant to torsion, shock and bumps, meeting the bearing capacity of different road surfaces.
