New 4 axles 80 tons lowbed low bed lowboy low boy truck semi trailer

TRUCKMAN Brand 80 ton low bed lowboy semi trailer is usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, construction machinery (such as excavators, bulldozers, loaders, pavers, cranes) and other heavy-duty goods. The lower the center of gravity, the better the stability and safety. The more capable it is to transport super-high cargo and pass overhead obstacles.

1. Side beams are usually channel steel or bending parts. At present, most trailers use channel steel. There are more side beams with light-weight bending parts because the strength requirement is not too big. Supporting beams are through beams. Now most of them are W beams.

2. The traction pin is an important component connecting the semi-trailer with the tractor and bearing traction force, which is connected with the traction seat. Generally, the steel with chromium alloy structure is forged. There are 50 traction pins and 90 traction pins for different tonnages of cargo. Generally, the total weight of 50T trailer and cargo is limited, 50# for below 50T, 90# for above 50T, and 90# for insurance purposes.
