Container Truck Trailer

Special transport vehicle for carrying containers. In the early stage of the development of container truck trailer, due to the small load capacity and small quantity of containers, ordinary trucks were often used for transportation. Since the 1960s, with the rapid development of container transportation, various countries have successively developed automobiles specially designed to transport containers. The size of the loading part of the container truck trailer is determined according to the size of the standard container, and a twist-lock device for fixing the container is provided at the position corresponding to the four corners of the bottom of the container.

Container truck trailer usually take the form of a combination of car trains. This combination includes semi-trailer, full-trailer and double-trailer, among which semitrailer car trains are mostly.

There are two types of semi trailers that make up the container truck trailer, the flatbed trailer and the skeleton trailer. The loading part of the flatbed semi-trailer is a flatbed, which can be used for shipping containers, and can also be used for shipping ordinary long-sized goods, and the use efficiency of the vehicle is high. The loading part of the skeleton semi-trailer is the chassis frame without the cargo platform. After the container is loaded on the vehicle and fixed by the twist lock device, it also becomes the strength member of the semi-trailer. Skeleton semi-trailers can only be used exclusively for shipping containers. It has the advantages of small weight, simple structure and convenient maintenance.

According to the structure, container semi-trailers are divided into two types: straight frame type and gooseneck type. Straight frame semi-trailer is suitable for shipping containers with flat bottom structure; gooseneck semi-trailer is specially used for shipping containers with groove bottom structure, which can reduce the loading height
