The invention relates to the field of large-scale storage and transportation, in particular to a tank container.

Background technique

Generally, a tank container includes a frame and a tank body placed in the frame. The frame includes two frames at the ends of the tank body. The tank body is used to transport liquid, gaseous, powdery and granular media. Due to the advantages of safety, speed, environmental protection and combined transport, tank containers have been more and more widely used in the logistics and transportation industry in recent years.

The capacity of the existing standard container is 20 feet, but when the goods to be transported are some low-density media, their weight is relatively light, which cannot meet the requirements of the standard container for transport weight, resulting in the unreasonable allocation of transport resources. Therefore, the existing general practice is to change the 20-foot tank container into a 30-foot tank container, that is, to lengthen the original 20-foot tank container to 30 feet along the length of the frame, thereby making the transportation resources more efficient. Reasonable configuration, however, in hoisting, transportation and other working conditions, it must be equipped with spreaders and tooling suitable for 30-foot tank containers.

In the prior art, in order to make the 30-foot tank container suitable for the spreader and tooling used by the 20-foot tank container, generally, two middle end frames with a distance of 20 feet from each other are set on the 30-foot frame. The corner fittings set on the end frame are hoisted.

However, the above-mentioned 30-foot tank container has four end frames in total due to the addition of two intermediate end frames and the original two end frames (these four end frames are used to meet the strength and hoisting requirements of the tank container. ), which increases the self-weight of the tank container and affects the loading weight of the tank container.
