[0005]

In the conventional container handling, stacking cones (weight of about 10 kg / piece) attached to the four corners of the lower surface of the container are attached and detached on the ground side by several land detaching workers. Because I'm going by
In addition to being disadvantageous in terms of cost, it is a heavy and dangerous work for workers.

Further, since the cone is attached to the container, the container cannot be directly placed on the pedestal, and the work is suspended and the cargo handling efficiency is poor. The present invention provides a container pedestal capable of mounting a container having a cone mounted thereon, removing the cone, and mounting a container having no cone mounted thereon and mounting the cone on the container. The purpose is.

[Means for Solving the Problems] A gantry on which a container is placed, a power source built in the gantry, a cone attaching / detaching mechanism installed on the gantry so as to correspond to a cone mounted on the container, and an unlocking mechanism. A cone taking-out mechanism for taking out the taken-out cone and a cone storing device for aligning and storing the taken-out cone are provided. The cone attaching / detaching mechanism is unitized in the container width direction to be replaceable, and further movable in the container longitudinal direction.

The container cradle constructed as described above is arranged on the other surface on the land side or in an appropriate place of the container crane, and the attachment and detachment of the stacking cone is automated.

[0009]

[Operation] On the container pedestal, it is possible to automatically perform the work of attaching / detaching, taking out and storing the cone to / from the container. Therefore, container handling work can be safely and efficiently executed. In addition, the cone attachment / detachment mechanism can be unitized and replaced, so that different types of cones can be handled immediately. Further, since the unit can be freely moved in the longitudinal direction, the cone attaching / detaching position can be arbitrarily adjusted according to the size of the container to be handled.
