Semitrailers are one of the main categories of trailers. They refer to trailers with axles positioned behind the center of gravity of the vehicle and equipped with coupling devices that transfer horizontal and vertical forces to the tractor. The semi trailer itself has no driving force, it needs to rely on the traction of the main car to achieve driving.Semi-trailer transport has high comprehensive economic benefits, which can be improved by 30-50% compared with ordinary monomer type cars.

With the continuous improvement of logistics transportation efficiency, the speed of trailer transportation is also improving, especially for medium and long distance transportation, the speed above 70 is common. But when the vehicle is fully loaded, dozens of tons of behemoths at high speed, once the accident, the results are often shocking, bumper, seat belt, airbag seems to be powerless.

On April 7th, it was learned from the Provincial Department of Transportation that the department, in conjunction with the Provincial Department of Public Security, the Provincial Department of Housing and Urban Rural Development, and the Provincial Data Bureau, has issued the "Several Opinions on Further Optimizing the Business Environment of Large Cargo Transportation in Hunan Province" (hereinafter referred to as the "Opinions"), promoting multiple measures that benefit enterprises and the people, such as "handling each matter once" for large cargo transportati

Annual inspection of motor vehicles is something that owners must do every year. But in the actual operation process, many owners will modify the trailer, some of which are legal, some of which belong to the category of illegal modification.

Semi-trailers are the main force in the domestic transportation market, especially in long-distance cargo transportation, semi-trailers almost dominate the world. The axle of a semi-trailer is generally installed behind the center of gravity of the vehicle, so it cannot maintain the balance of the body independently.

Tank semi-trailer refers to a semi-trailer with a tank structure in the container. It is more common in transportation operations. It is widely used in industry, agriculture, commerce and other fields under normal circumstances. It is mainly used to transport oil, gas, bulk Materials etc.According to the type of goods transported, tank semi-trailers can be subdivided into the following categories:1.

If you want to ask which model in the trailer transportation industry is the best for loading, many car owners will invariably think of 17.5 large trucks.

The freight market has almost become the world of large trucks. The original length of 17.5 vehicles is already a huge loading capacity. Some car owners pursue higher profits.

In recent years, our logistics transportation industry has gradually developed in the direction of intensification and high efficiency, logistics enterprises to the demand for efficient vehicles is more urgent. Compared with the "monomer type" vehicle, the transport efficiency of semi-trailer can be improved by about 30%-50%, but the transport cost is reduced by about 30%-40%.

With the strengthening of traffic management departments on overload transport control, vehicle lightweight gradually become an industry trend, more and more vehicle owners in the purchase of trailers and accessories, more inclined to choose those stable performance but their own weight lighter products, which also to a certain extent promote the trailer, accessories manufacturers in materials, technology, structure and other aspects of continuous optimization and improvement.In general, the trailer wants to achieve light weight, the common way are the following.1, reduce the thickness of the
