Bridge crane or gantry crane comprising a revolving arrangement and lifting frames suspended thereunder

A bridge crane or gantry crane for handling standard load carriers, said crane comprising:

• a crane carrier;
• a crane trolley that is movable along the crane carrier in a trolley travel direction;
• a rigid, single-pieced and non-telescopic mast guided on the crane trolley, wherein the mast extends in a lifting and lowering direction;
• at least one lifting mechanism comprising a cable drum, a common drive and a drive motor disposed at the crane trolley for moving the mast in the lifting and lowering direction via cables;
• a load-receiving device for standard load carriers attached at a lower end of the mast, wherein the mast is suspended on the crane trolley so as to be rotatable about an axis of rotation extending in the mast's longitudinal direction;
• a revolving arrangement on the crane trolley, the revolving arrangement including a revolving pipe with an upper end and a lower end, the upper end of the revolving pipe supported on the crane trolley via a revolving connection;
• a lifting frame suspended by the revolving arrangement via attachment of the lifting frame to the lower end of the revolving pipe, the lifting frame supporting the lifting mechanism for moving the mast in the lifting and lowering direction via cables running between the lifting frame and the load-receiving device;
• and
• wherein the mast is arranged coaxially to the revolving pipe and is guided in such a way that the mast can be raised and lowered in the revolving pipe, and wherein the lifting frame is disposed below the crane carrier.
