The difference between middle axle trailer and full trailer

With the continuous strengthening of governance in all aspects of highway transport industry, the word "middle axle trailer" is also appearing more and more frequently in the line of sight of owners, and even in GB1589, there are new middle axle trailer models. Some owners may ask: what kind of vehicle is the middle axle trailer?

In popular terms, the middle axle trailer is the trailer whose axle is located in the center of the vehicle's center of gravity. If a single view is taken on the model of the shaft trailer, some old drivers even think that the middle axle trailer looks more like the whole trailer. In fact, the difference between the two is relatively obvious:

1. The axle of the middle axle trailer is located in the center of gravity of the body, and it cannot support its own weight independently when it leaves the tractor; Full-trailer axles are located at the front and rear ends of the body and can stand smoothly even without the support of the tractor.

2. The traction device of the middle axle trailer can not move up and down; Full trailers, on the other hand, have traction devices that can swing either up and down or from side to side.

3. The middle axle trailer is mainly composed of carriage, axle and traction device, without bogie; The full trailer is composed of carriage, axle, bogie and traction device, which can be turned along with the driving direction of the tractor.

4. The traction hook connected with the main car and the middle axle trailer is located under the frame and indirectly connected with the frame; The full trailer is connected to the main car by a traction hook mounted on the frame of the main car.

5. Compared with full trailer, reversing of middle axle trailer is relatively simple.

Compared with other trailers, middle-axle trailer has the advantages of low center of gravity, light weight, simple structure, etc., but because it is only suitable for use on high-grade highways, it is relatively more suitable for special line logistics users with fixed goods. In addition, the load of the middle axle trailer is relatively stable, the force is relatively simple, it is suitable for the use of lightweight materials and lightweight design to achieve greater benefits.

So how is the standard of middle axle trailer established?

According to GB1589 standard, the outer length of the middle axle trailer shall not exceed 12m, the width shall not exceed 2.55m and the height shall not exceed 4m; The length of the outer outline of the train transported by the middle axle vehicle shall not exceed 22m, and the width and height shall be the same as that of the middle axle trailer. On the maximum allowable total mass limit, the limit of one-axle axle trailer is 10t, the limit of two-axle axle trailer is 18t and the limit of three-axle axle trailer is 24t.

With the continuous development of mid-axle trailer, the status quo of semi-trailer in the future logistics and transportation industry will also change. Various models will play a role in their respective fields of expertise, and jointly improve the efficiency of logistics and transportation. DARO Group is one of the first domestic enterprises to mass-produce all-in-one trailer axles. It has been focusing on the production and sales of trailer axles for 20 years with reliable quality and stable performance. It has become a fixed cooperative brand of many trailer factories, logistics enterprises and retail investors.
