What is the longest meter of a compliant central axle trailer?

In the freight industry, trailers can be mainly divided into three types: semi-trailer, full trailer, and central axle trailer. Among them, full trailers and semi-trailers appeared in my country relatively early, and car owners are familiar with them, while central axle trailers Its popularity in China is not high, and car owners have relatively little contact with it.

After the update of GB1589, the central axle trailer has become a model encouraged by the policy, and its market popularity has continued to rise. Many car companies have also declared the center axle trailer model.

So, according to the requirements of the regulations, how many meters can the center axle trailer be made at the longest? This should be determined according to the model of the center axle trailer.

The length of the outer profile of the central 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 profile of the center-axle vehicle transport train can reach up to 22m, and the width and height limits are the same as those of the center-axle trailer;

The maximum length of the outer profile of the central axle freight car is 20m, and the width and height are the same as that of the central axle trailer.

As for the total mass limit, the limit for one-axle center-axle trailers is 10t, the limit for two-axle center-axle trailers is 18t, the limit for three-axle center-axle trailers is 24t, and the maximum total weight limit for four-axle center-axle trucks is 36t. The maximum total weight limit of five-axle center-axle freight trains is 43t, and the total weight limit of six-axle center-axle freight trains is 49t.

Among the above-mentioned models, the central axle trailer is similar to the semi-trailer, except that the axle is installed in a different position, and the types of goods loaded and transported are generally unlimited;

Center-mounted axle vehicle transport trains refer to center-mounted axle car transport vehicles, which are specially used to transport small passenger vehicles such as cars and vans;

Center-axle freight trains are more used in the field of general cargo transportation, such as express mail, less-than-truckload, and light cargo transportation. The upper structure is mainly box-type, with a volume of up to 120 cubic meters. After the emergence of transportation, the central axle truck trains can be detached flexibly, which can quickly realize the replacement of trailers, and improve the efficiency of loading, unloading and transportation.

In addition to the advantages in loading capacity, the central axle trailer also has the characteristics of low center of gravity and low chassis, which can improve driving stability, reduce the height of the compartment to a greater extent, and increase the cargo loading space within the scope of compliance; secondly, The curve passability of the central axle trailer is relatively strong, because its axle is in the middle of the car, the wheelbase is short, and the turning radius is small, so the central axle trailer can often be made longer under the same turning radius.

Because of this, the popularity rate of center-axle trailers is very high abroad, and it has almost become the main model of European and American trailers. However, since the popularization of the central axle trailer, the response to it in the domestic market has been mediocre. What is the reason?

It is mainly based on differences in national conditions. It is understood that in the European and American freight markets, the operation of road transport vehicles requires fast loading and unloading, high barge efficiency, common drop-and-hook mode, good transportation order, dedicated vehicles, and high illegal costs for overloading and exceeding the limit, which has almost reached standardized operation. Coupled with its vast land and sparsely populated roads, the length of the center-axle trailer has been relaxed to 25m with a higher loading rate. These factors have promoted the development and application of center-axle vehicles to a certain extent.

In addition, the disadvantages of central axle trailers that cannot be ignored have also become factors restricting their development in China, such as high purchase costs, high requirements on road conditions, difficult driving, unstable freight market, limited application scenarios, product The technology is not mature enough, etc., which discourage car owners.

It is worth mentioning that the domestic exploration of central axle trailers is still in its infancy, and the transportation environment is gradually improving. According to the advantages of central axle trailers and the gradual trend of dedicated, modular and standardized transportation In the future, the central axle trailer may occupy a certain market space, and the market coverage of various accessories that match it will further increase.

The DARO recessed trailer axle is specially designed for center axle trailers. The connection between the axle beam and the wheel end presents an inverted door-shaped structure, which can further reduce the height and center of gravity of the vehicle chassis, while ensuring the load-bearing capacity, it also expands the cargo loading space and improves driving stability. sex.
