This dry container is a box-shaped container having a rectangular parallelepiped shape in order to protect cargo from external factors of destruction and damage and to facilitate loading on the transportation means. Compared to special containers such as flat containers that do not have a ceiling and open top containers that can open the ceiling, this dry container is generally high in number, inexpensive, easy to secure, and airtight. It has the advantage of being excellent.
However, the dry container is provided at the rear end side where the carry-in / out port of the conveyed goods is the smallest side surface, and the carrying-in / out work of the conveyed goods to / from the dry container through the opening at the rear end side {banning (including devanning) Also say. } Is performed. Therefore, when carrying in / out a conveyed product to / from a dry container, particularly when the conveyed product is a heavy and heavy conveyed product, the carrying-in / carrying-out work is extremely difficult. In other words, except for specific heavy goods that can be carried using small forklifts and other carriers that can enter dry containers, most heavy goods (long objects, large cargo, etc.) are carried out to dry containers. It was almost impossible to enter. Therefore, it was the current situation that the above-mentioned heavy goods were carried into a special container (open top container, flat rack container, etc.) using a special carrier (crane, large lift, etc.) instead of a dry container.
