Description

  The present invention relates to a transport apparatus and a method for transporting a load into a container from a transport port provided on a peripheral side wall of the container.

  In recent years, transportation using containers is increasing from the viewpoint of reducing transportation costs and packing costs. A container usually has to be loaded from a transfer port provided on a side wall of the container, and there is a problem that a loader must work in a dangerous environment such as the inside of a narrow container.

  In addition, it is necessary to repeat a small amount of loading due to the restriction of the size of the transfer port, so the handling efficiency is poor, especially when the load is loose, it can not be loaded with a pallet, so loading with a power shovel etc. There is a problem that it is difficult to perform the loading operation because the transfer port is provided on the peripheral side wall of the container.

  On the other hand, it is conceivable that the container is tilted so that the transfer port faces upward, but it is difficult to arrange the load inside the container uniformly, and the container shell is excessively large during loading. In addition, there is a problem that a large load is easily applied and damage is easily caused. Further, when the container becomes large, there is a problem that a hoist for tilting the container becomes large.

Therefore, in addition to the transfer port on the peripheral wall of the container, a loading port with an open / close hatch is formed at the top of the container outer shell, so that the container can be loaded into the container from the loading port using a power shovel without tilting the container. However, in such a case, the container has to be remodeled, and there is a problem that the container is not versatile and the transportation cost is increased.
