Abstract
Abstract A container handling apparatus is formed of a travelling container crane, a self-supporting portal frame supported by wheels, a connector connecting the container crane with the portal frame, container receiving device provided on the portal frame and container elevating device provided on the portal frame, thereby the container crane handles a container to the container receiving means provided on the portal frame, the container is handled from the container receiving device to the container elevating device, and the operation efficiency is increased between the container crane and the container elevating device, a contact point of each handling path is fixed by the connector not to be discrepant each other so as to maintain continuity of the handling paths, further, during handling operation, a load received by the container handling apparatus is prevented to transmit concentrically to the container crane by the self-supporting portal frame, and that a large number of the containers may be handled in a short period of time without unreasonable use of the container crane.
