In China's port, airline, highway, transfer station, bridge and tunnel logistics system, there is a commonly used vehicle - container trailer, which has large volume, large transportation volume and high transportation efficiency. It usually adopts semi-trailer, full trailer or double trailer, mostly semi-trailer. Semi-trailer can be divided into flat plate type or skeleton type, which belongs to a special semi-trailer.

Different from other semi trailers, container semi trailers are mainly used to transport containers. The containers loaded with goods are directly loaded on the trailer from the delivery warehouse and transported to the harvest warehouse for unloading. If the vehicle and ship need to be changed in the middle, only the container needs to be moved, and there is no need to unload or load the goods scattered, so rapid loading and unloading can be realized, Changing directly from one means of transport to another can greatly improve the efficiency. At the same time, it is also conducive to the filling and unloading of goods, meet the personalized needs of customers, have stable quality and reliable performance.

Among semi trailers, there is another type of vehicle - Van semi-trailer. Are container semi-trailer and van semi-trailer the same type?

Answer: not the same model. Although the two semi trailers are equipped with cargo compartments, which can be used to transport goods, and the names are quite different, there are still some differences:

1. The structural design is different.

The cargo box of container semi-trailer belongs to the category of goods and is integrated with goods. Its body is only the frame, and the cargo box can be unloaded together when unloading; The cargo box of van semi-trailer belongs to the category of vehicle body. The goods are only loaded in the cargo box. When unloading, the goods need to be taken out from the cargo box.

2. The length limit is different.

According to relevant regulations, the length limit of container semi-trailer is 13.95m, which mainly takes into account the length of container. For example, the length of semi-trailer capable of transporting 45 foot container is 13.95m; The length limit of van semi-trailer is 13.75 meters.

3. Different uses.

Container semi-trailer is specially used to transport containers, dangerous goods, tanks and other special goods; Van type semi-trailer is mainly used to transport household appliances, light textile goods, coal, gravel and other building materials or drawing plate goods.

4. The loading capacity is different.

Generally speaking, the cargo loading capacity of container semi-trailer is larger than that of van semi-trailer.

5. Different safety performance.

The safety performance of the semi-trailer is closely related to many factors, but if only from the perspective of vehicle structure, because the carriage of the container semi-trailer is not integrated with the body, it is connected by a special locking structure. If it meets the emergency brake under the condition of full load, it is easy to cause damage to the cargo compartment, and even the cargo compartment rushes to the cab, threatening personnel safety.

For car owners, which model is better needs to comprehensively consider various factors, such as the type of goods they load, the weight of goods, the road conditions of frequent routes, the budget of car purchase, etc. only those that meet their own needs are suitable models.

Whether it is a container semi-trailer or a van semi-trailer, the choice of axle is very important. As a key component on the trailer chassis related to vehicle load-bearing, braking and driving, the strength, toughness and durability of axle must be strictly up to standard. Darong group is the first axle enterprise in Liangshan special vehicle production base to mass produce integrated axles. So far, it has accumulated 20 years of production experience, and its technology and strength rank among the forefront of the industry. The shaft body and shaft head of Darong axle are polished and formed on the same high-strength alloy steel pipe, which is superior to the welded shaft head in terms of heavy load performance. There are 15 production processes such as 1300 ℃ hot rotary rolling, 865 ℃ medium frequency quenching, 480 ℃ heat preservation treatment and CNC precision grinding, which are in strict compliance with the industry standards. The upper + lower quality inspection of the connecting line, the product quality is strict and up to the standard, and fully meet the use needs of users.
