What is a lowbed/lowboy semi trailer?

Lowbed semi trailers are widely used, mainly for medium and long-distance freight transportation. low deck trailers are commonly used to transport heavy vehicles, rail vehicles, mining machinery, forestry machinery, agricultural machinery, and other heavy-duty cargo.

The low bed trailer structure usually adopts a concave beam frame. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high cargo. The front section of the frame is a gooseneck (the traction pin in 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) Cargo platform (the lowest part of the frame), the rear end is the wheel frame (including wheels).

History of low flatbed trailer

The first trailer we know today was invented in the 1920s. Early models had riveted goosenecks, which were hung from the front of the trailer to the truck. Because of this design, any operable equipment must be driven to the deck above the rear tires.

In the 1950s, heavy load trailers had a new design. In 1958, a removable gooseneck or removable gooseneck (RGN) was added to make loading easier.

Modern lowboy trailers typically work with hydraulic systems; a hydraulic ram lifts the trailer to meet the unit post-loading. They also include air breaks and are towed by semi-trucks.

Features of low bed semi trailer

1. The series of lowbed trailers have flat-plate, concave beam and exposed tire structures, and the longitudinal beams are straight or gooseneck. The frame is stepped and the longitudinal beam section is I-shaped. It has the characteristics of high rigidity and high strength.

2. The main plane of the frame and cargo platform is low, which ensures the stability of transportation and is suitable for carrying various types of engineering machinery, large equipment and steel.

Maintenance knowledge about heavy transport lowbed trailers:

1. The height of the low deck trailer work platform is determined by the size of the tires and the leaf springs.

For example: 12R22.5 tires are installed, the leaf spring is reverse mounted, and the working platform height is 1.2m. Under the premise of this configuration, reduce the height of the working platform. That only shortens the height of the main beam.

So, equipment trailer friends when customizing new trailers, don't blindly reduce the height of the working platform. The shortening and narrowing of the main beam will directly affect the load capacity and service life of the step deck trailer.

2. When does the brake pad change?

For transportation safety, stable braking performance is essential. Always check the brake system, when checking the wear level of the brake pads. We can check it through the observation hole.

The limit thickness of Fuhua axle brake pads is 6mm, when it is worn to a limit, It must be replaced.
