Background technique

As a multimodal cargo transportation tool, containers have been widely used around the world. In addition to standard shipping containers that are commonly used around the world, there are also containers with special functions used regionally, such as North American 53-foot containers. These containers are divided into North American inland 53-foot containers and maritime 53-foot containers. , among which, compared with the 53-foot container transported by sea, the 53-foot container transported in North America has the characteristics of high door opening, tall interior and large volume. However, due to the size and structure limitations of the corner parts, it is necessary to use a transshipment platform to achieve liner transportation and stacking during sea transport. The number of layers is generally 3. During liner transportation, the number of stacking layers of 53-foot shipping containers can reach 6-8, but the internal volume and door opening height are smaller than those of 53-foot inland shipping containers. Due to the lack of 53-foot containers that are common for both land and sea transportation, the process of container land transportation and sea transportation is cumbersome and the consumption cost is high.
