In the freight industry, the gooseneck semi-trailer is widely used, and is applicable to the transportation of various mechanical equipment, large objects, highway construction equipment, large tanks, power station equipment and various steel materials.

Gooseneck semi-trailer generally has a gooseneck in the front section, a cargo platform in the middle section, and a wheel frame in the rear section. There is no fence around it. From the structural point of view, it can be divided into flat type, concave beam type and tire exposed type.

Compared with the ordinary semi-trailer, the gooseneck semi-trailer can reduce the center of gravity of the vehicle, improve the driving stability of the vehicle, and improve the trafficability on the high-limit section.

When buying a car, people often hear the salesperson say "big goose neck" and "small goose neck". How do you distinguish the two semi-trailers?

In fact, it is mainly based on the height of gooseneck. Generally speaking, the height difference between the gooseneck and the cargo platform of the large gooseneck semi-trailer is more than 300 mm, and the cargo platform height is ≤ 1300 mm; The height difference between the gooseneck and the cargo platform of the small gooseneck semi-trailer is relatively smaller, and the cargo platform height is also relatively higher.

At present, the relevant departments are increasingly strengthening the control of overload. Even the height of container semi-trailer can not exceed 4m. From this point of view, the large gooseneck semi-trailer can better reduce the height and center of gravity of the cargo platform, and solve the problem of vehicle superelevation, without exceeding the limit, and at the same time, the center of gravity is stable, which is conducive to driving safety.

It is worth noting that the gooseneck is the gooseneck part of the semi-trailer, which is not allowed to load goods. This is an explicit regulation of the Ministry of Industry and Information Technology. The owners should strictly abide by it to avoid fines or points deduction.

Some car owners asked: Can the gooseneck semi-trailer transport ordinary goods? This problem should be analyzed from the model of gooseneck semi-trailer.

Generally, gooseneck structure mainly exists in low flat semi-trailer, special skeleton vehicle for container transport and some vehicle transport semi-trailer (car transport vehicle).

If it is a low flat semi-trailer or a car carrier, it must not be able to transport ordinary goods, because these two kinds of semi-trailers are special vehicles, of which the low flat semi-trailer is used to transport "large and non-detachable" goods, and the car carrier is used to transport passenger vehicles, and it is illegal to transport ordinary goods according to the regulations.

If it is a skeleton gooseneck semi-trailer specially designed to transport containers, it is no problem to transport ordinary goods, because for container transport semi-trailers, the container belongs to the category of goods, not the body structure, and it is completely possible to load ordinary goods in the container.

Gooseneck semi-trailer has certain particularity in application field, and its accessories are also different from ordinary semi-trailer. For example, the rear axle and gooseneck semi-trailer platform are small in height, and the selected axle should also conform to the characteristics of high load bearing and low center of gravity. The low flat axle produced by Darong Group is specially made for the gooseneck semi-trailer. Not only is the height from the ground significantly smaller than other axles, but also the wall thickness of the axle body is higher than that of the ordinary axle. In addition, the brake drum, brake pad, bearing, bolt, etc. are also special for the heavy-duty semi-trailer, and the strength, toughness, wear resistance and other indicators are also higher.
