The invention relates to a fixed-column-type cantilever crane which comprises a rotating base, a lifting device, a cantilever device and a rotating cantilever powder device. The rotating base can rotate freely by 360 degrees and is an installation platform for the lifting device, the cantilever device and the rotating cantilever power device. The lifting device can control taking-up and paying-off of a steel wire rope and then controls ascending and descending of a lifting hook. The cantilever device stretches the lifting hook on the steel wire rope out by a certain distance, and the lifting hook gets away from or is close to the rotating base within the certain range through pitching of the cantilever device. The rotating cantilever power device is matched with two clutches through a motor, and the rotating action and the pitching action of the cantilever device can be performed respectively. The fixed-column-type cantilever crane can be used for lifting an object lighter than one ton and has the beneficial effects that the structure is compact, the size is small, and the cantilever device can pitch.
