Special transport vehicles for container vans. In the early stage of the development of container transportation, because the container load is small and the quantity is not large, it is mostly carried by ordinary trucks. Since the 1960 s, with the rapid development of container transport, countries have developed a car dedicated to the transport of containers. The size of the loading part of the container car is determined according to the size of the standard container, and the twist lock device for fixing the container is provided at the position corresponding to the four corners of the bottom of the container.
Container cars usually take the form of a combination of cars and trains. This combination is semi-hung, full-hung and double-hung, of which semi-hung cars and trains are the majority.
There are two types of semi-trailers that make up the container car train: flat type and skeleton type. The loading part of the flatbed semi-trailer is a flatbed cargo platform, which can be used to ship containers or ordinary large and large cargo, 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 car and fixed by the twist lock device, it also becomes the strength member of the semi-trailer. Skeleton semi-trailers can only be used for the purpose of shipping containers. It has the advantages of small weight, simple structure and convenient maintenance.
According to the structural form, the container semi-trailer is divided into straight frame type and gooseneck type. The straight-frame semi-trailer is suitable for loading containers with flat-bottom structure; the gooseneck semi-trailer is specially used for loading containers with grooved bottom structure, which can reduce the loading height.
