The dump truck is a kind of model widely used in the semi-trailer, especially in the transportation of loose goods such as sand and gravel, soil, coal, and grain, which plays a great role in improving the unloading efficiency, shortening the transportation cycle, saving time and labor.The traditional semi-trailer is made of steel, mainly high-strength alloy steel; With the prevalence of the trend of lightweight trailers, in some areas, steel trailers began to be gradually replaced by aluminum trailers, and the price was also a big cut higher.But have you ever seen a trailer made of stainless s

In everyday life, we sometimes see or hear the term "tractor-trailer". What is "tractor-trailer"?

Check the appearance of the axle: Check if there are any obvious damages, cracks, or deformations on the appearance of the axle.

For the rear axle of the trailer, many owners think that it is simple in structure and low in technical content, but it is not. As a driven bridge, although the design complexity of the rear axle of the trailer is not as good as that of the drive axle, it bears the bearing, braking, driving and other performance of the vehicle, which is directly related to driving safety.It is very simple to produce a trailer rear axle, but it is not simple to produce a trailer rear axle with good performance.

The axle is one of the core components on the trailer, and its quality and performance are directly related to the driving safety of the trailer, such as load bearing, braking, maintenance and so on.

Trailer is a type of vehicle that does not have its own driving force, and needs to be powered by a tractor to drive, from a structural point of view, it can be mainly divided into full-mounted, mid-mounted and semi-mounted, of which full-mounted and mid-mounted axles are more common.Full hangingCenter axle typesemi-hangingThe application field of trailer is very wide, warehouse, factory, port, dock, farmland, road, field, etc., almost can see their figure.Due to the different working conditions, the functions of the trailer are also very different.
