All along, various controversies about green transportation seem to have been ongoing. Previously, more attention was focused on the issue of certain agricultural products not belonging to green currency, such as virgin fruit, chili peppers, baby cabbage, beetroot, sugarcane, etc. Nowadays, in addition to this type of problem, there is also a question about the height limit of vehicles: can the total height of vehicles and goods exceed 4m from the ground be taken through the free green channel.

According to the Notice on Further Optimizing the "Green Channel" Policy for the Transportation of Fresh Agricultural Products issued by the Ministry of Transport, the Development and Reform Commission, and the Ministry of Finance, vehicles that legally load and transport products within the national unified "Catalogue of Fresh Agricultural Products" are exempt from vehicle tolls. If the total height of the vehicle and cargo exceeds 4m from the ground, it is considered an illegal and overloaded transportation vehicle and cannot enjoy the green channel policy for transporting fresh agricultural products.

This regulation can be said to clearly include green traffic with a total height of over 4m between the vehicle and cargo in the scope of over limit transportation, which can be implemented, especially for container green traffic such as refrigerated vehicles, where conflicts arise.

According to the provisions of the first paragraph of Article 54 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China issued by the State Council, the height of heavy and medium-sized truck and semi trailers from the ground shall not exceed 4m, and the height of vehicles carrying containers shall not exceed 4.2m.

That is to say, as long as the height of the vehicle carrying containers does not exceed 4.2m, it is not illegal.

Which regulation should be followed for container green traffic, with a total height of vehicles and cargo not exceeding 4m and a height of vehicles and cargo not exceeding 4.2m?

Based on the current situation, some regions such as Liaoning, Hebei, Inner Mongolia, Henan, and Hunan have introduced new regulations on highways. If the total height of vehicles and goods exceeds the maximum limit of external dimensions, green passage fees will not be exempted. This means that only designated fresh agricultural products can be loaded according to regulations and transported legally and compliant can tolls be exempted. The 4.2m green passage of containers is an act of exceeding the limit, and the green passage policy cannot be applied.

Although the standard has not yet been clearly unified, there are no fewer car owners who have paid the toll in full for more than 4.2m in the market. In order to enjoy the free passage policy, the safest way is to limit the height of cars and goods to within 4m.

But for the green opening of containers, do we really need to cut off the super high box body?

In fact, since the release of the "super high" news, the orders of cabinet modification factories in multiple cities across the country have been fully booked. However, whether the airtightness, insulation, and waterproofing of the cut and sewn box body can be consistent with the original one may depend on the effectiveness of the modification. Furthermore, after the modification of the cabin, the loading space will inevitably decrease, and the number of goods that can be loaded may also decrease, which will have a certain impact on operational revenue.

If the car owner is using a container semi-trailer, they can also start renovating from the saddle: one is to remove or replace thinner saddle pads to reduce the height of the saddle to a certain extent; Another option is to replace low saddles with "ultra-thin" thickness, which can be 4-5cm thinner than most saddles on the market, further reducing the height of the saddles above the ground.

In addition, car owners can also choose to install an airbag bridge. By adjusting the air pressure inside the airbag and adjusting the height of the airbag, the suspension can be lowered to the lowest position during inspection, and the top ground height can be effectively controlled.

It is worth mentioning that air suspension can also be divided into two types: American and European. Among them, the American air suspension guide arm has a light weight, a larger contact area with the axle, better lateral support, and is more suitable for use in good road conditions; The European style air suspension adopts the leaf spring guide arm, such as the air suspension produced by Darong Group, which has good load-bearing performance, long airbag travel, better shock absorption effect, and is more suitable for the domestic transportation environment with complex road conditions and heavy loads. It has a long service life and high bearing strength. It can effectively reduce the loss of goods and improve the operation efficiency with the Darong axle.
