The present invention appropriately increases the strength of the bottom frame of the semi-hanging container by using a larger specification material, the strength of the bottom side beam can be increased by about 1 times that of the conventional container, and the strength of the bottom beam is increased by 1.3 times than that of the conventional container. The requirements for high strength of the base for land transportation. At the same time, because land transportation does not stack several containers to be transported like container shipping, the material specifications of corner posts, side components and top components can be appropriately reduced. Therefore, compared with the traditional container, the semi-trailer container of the present invention has a similar weight when the same volume is used.

While the strength of the semi-trailer container chassis is increased, the strength of the dedicated container semi-trailer can be greatly reduced. The special container semi-trailer of the present invention only uses a high-strength load beam at the legs and wheels, which simplifies The structure of the traditional container semi-trailer reduces the material cost of the entire vehicle and makes it more flexible to meet the requirements of different length semi-trailers.

The semi-trailer container of the present invention has the basic characteristics of a marine container. It has a corner piece lifting hole at an appropriate position. Therefore, the existing container lifting equipment can lift the box, and it can also be used for ocean empty container delivery by a container ship. Because its external structure is similar to a container, it can directly use the existing collection Box production line for mass production. The purpose of a semi-trailer container is not to use it as a container, but to use it as the top load of a van semi-trailer. It has a detachable traction pin and traction slide assembly on the front bottom surface, which is different from ordinary containers. The traction pin and traction slide are standard assembled and bolted after the product is delivered to its destination. The bottom side beam of the semi-hanging container of the present invention has higher strength than the bottom side beam of the shipping container, and the strength of the bottom cross beam is also higher than that of the shipping container. In addition, the overall rigidity and strength are greatly improved. Because semi-hanging containers are used on land, the requirements for the side wall tests are not strict, and there is no stacking test. Therefore, the materials for the upper compartment structure can be reduced, while the materials for the bottom side beams and bottom cross beams are increased, but The total weight is essentially unchanged. Since the semi-trailer container itself has coupling parts with the traction pin and the traction slide assembly, outriggers, and sub-frames, and the structure is good, the semi-trailer to be matched with it only needs a few major components: the traction pin and The structure of traction skateboard, outriggers, subframe, rear bumper, etc. is greatly simplified. The connection between the semi-trailer container and its special container semi-trailer is fast-locked through the mounting holes on the semi-trailer container and the locking device at the end of the trailer beam, which is convenient and reliable.
