  • Publication number: 20020003996
    Abstract: Disclosed is a container loading and unloading apparatus, which overcomes a problem of a conventional container in that a special equipment such as a forklift truck, a crane or the like is necessarily mobilized whenever the loading or unloading work is performed because the container is simply a cuboidal rigid body. The present invention makes it possible to perform the loading and unloading works of the container main body at the time of its storage and transportation without a separate loading and unloading equipment by providing a container supporter to secure a space for loading the container main body on a chassis of a freight car, thereby reducing equipments and labor as well as facilitating the loading and unloading works.
