This invention discloses a crane with an end beam hanging trolley and a rotating mechanism with fan gear transmission. The crane includes a double-beam bridge frame. The two ends of each end beam of the bridge frame are each provided with a big trolley driving device and a rollover preventing device. The lower portion of a main beam of the bridge frame is provided with tracks and a trolley stop. The two tracks are connected with the end beam hanging trolley. The rotating mechanism with the fan gear transmission is arranged on the end beam hanging trolley. The lower end of a hanger shaft in therotating mechanism is connected with a cantilever member. The upper end of the hanger shaft is connected with a safety ruler. Two stroke switches are connected with the upper surface of a small trolley frame. The cantilever member is provided with an electric hoist which can move back and forth along a cantilever beam. The cantilever beam is located at the lower portion of the main beam and can rotate. The cantilever end of the cantilever beam is connected with a trolley stop device, and the position of the trolley stop device is adjustable. The two end beams on the double-beam bridge frame are connected with electric power frames. A steel cable rail is connected between the two electric power frames. The steel cable rail is connected with a hanging cable. One end of the hanging cable iselectrically connected with the end beam hanging trolley.
