Abstract

A bridge crane or gantry crane is provided for transferring standard cargo holders, especially ISO containers in port zones. A crane trolley is movable along a crane carrier. A rigid mast is guided on the crane trolley and extends in a raising and lowering direction and can be moved using at least one lifting gear and cables on the crane trolley. A load accepting device for standard cargo holders is fastened to the lower end of the mast. The mast is rotatable about a longitudinal rotational axis. A lifting frame supports the lifting gear and is suspended on the crane trolley by a revolving arrangement that includes a revolving tube. An upper end of the revolving tube rests against the crane trolley using a revolving joint, while the lifting frame is mounted on a lower end of the revolving tube. The mast is arranged coaxially to the revolving tube.
