What is the characteristics of the lowbed semi trailer？

the characteristics of the lowbed semi trailer

the lowbed semi trailer are usually used to transport heavy duty trucks (such as tractors, buses, special purpose vehicles, etc.), rail vehicles, mining machines, forestry machines, agricultural machines (such as excavators, bulldozers, loaders, road pavers, cranes, etc.) and other heavy loads, the lower the center of gravity, the better the stability and safety, and the greater the ability to transport super high loads and pass overhead obstacles.

the lowbed semi trailer is also widely used for transportation of various mechanical equipment, large objects, road construction equipment, large tanks, power station equipment and various steels.

the Lowbed semi trailer structure and loading：

the Lowbed semi trailer usually adopts concave beam type (or well type) frame, that is, the front section of the frame is a gooseneck (the traction pin of 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. connected), 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 the lowbed semi trailer, the lowbed semi trailer is usually loaded from the rear end of the low semi trailer, the lowbed semi trailer that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment on the lowbed semi trailer. superior.

Features：

1. The lowbed semitrailer series has flatbed, concave beam and tire exposed structure, and the longitudinal beam is straight or gooseneck. The frame is stepped, and the longitudinal beam section is I-shaped, which has the characteristics of high rigidity and high strength.
2. The main plane of the frame and platform is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large scale equipment and steel.

3. It adopts threeaxis balance type, two-axis balance type or rigid suspension, and a mass balance block is installed between the front and rear leaf springs, which can make the deflection of the front and rear leaf springs change in an equal amount, so that the front and rear axles are balanced.
4. The lowbed semi trailer series products are suitable for the transportation of various kinds of mechanical equipment, large objects, highway construction equipment, large tanks, power station equipment and various steels. They are widely used, the lowbed semi trailer efficient and fast. The whole vehicle adopts advanced computer aided design software, and the optimization design is flexible and diverse, and the frame bearing surface the lowbed semi trailer is designed according to user requirements to meet the transportation of various special goods.

The lowbed semi trailer is mainly used to transport bulky goods that are not easy to be broken down, such as excavators, etc. The fence type is more suitable for pulling fresh goods, such as vegetables, fruits, etc. The van type is more suitable for pulling bulk goods And moisture proof more valuable goods.

Side beams are generally channel steel or bending parts. At present, most trailers use channel steel, and there will be more side beams for light body hanging bending parts, because the requirements for strength are not too large. The support beam is the through beam, and now most of them are W beams (the above picture shows the W beam as the through beam), and only use 10# or more channel steel for heavy cargo.

The traction pin is an important component that connects the lowbed semi trailer and the tractor and bears the traction force, and is connected to the traction seat. It is generally forged from steel with a chrome alloy structure.
