Low-bed semi-trailers are 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, etc. ), and other heavy cargo. The lower it’s center of gravity, the better its stability and safety, and its ability to transport very high loads and negotiate overhead obstacles.

Structure

Low-bed semi-trailers usually use a concave beam (or well-type) frame. The front part of the vehicle frame is a gooseneck (the traction pin at the front part of the gooseneck is connected with the traction saddle on the tractor. The rear end of the gooseneck is connected with the semi-trailer frame). The middle section is the cargo platform (the lower part of the frame), and the rear end is the wheel frame (including the wheels).

Load

When loading mechanical equipment on a low-bed semi-trailer, it is usually loaded from the rear 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 on the semi-trailer.

Features

The low-bed semi-trailer also has a wide range of cargo, which is suitable for the transportation of various mechanical equipment, large objects, road construction equipment, large tanks, and power station equipment.

Low plate

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

Cargo rack

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

Three-axis balance

3. Adopt a three-axis balance type, two-axis balance type, or rigid suspension, and a mass balance block is installed between the front and rear leaf springs so that the deflection of the front and rear leaf springs can be changed in equal amounts so that the force on the front and rear axles can be balanced.

4. The low-bed semi-trailer series products are suitable for the transportation of various mechanical equipment, large objects, road construction equipment, large tanks, power station equipment, and various steel materials. They are widely used, efficient, and fast. The whole vehicle adopts advanced computer-aided design software, and the optimization design is flexible and diverse. The load-bearing surface of the frame is designed according to user requirements to meet the transportation of various special goods.

Type

The main types of low-bed semi-trailers are two-axle high-low height, two-line four-axle high-low height, three-axle high-low high, and three-line six-axle high-low high.

Load

The number of axles, the size of the tires, and the load of the low-bed semi-trailer are also different. The more the number of axles, the greater the load, and the load range is between 20-150 tons.
