The invention discloses a rotating crane. The rotating crane comprises a base, a stand column, a rotating core shaft, a cantilever, a movable trolley and a balance weight mechanism. The stand column is perpendicularly fixed to the base, and the rotating core shaft is rotatably arranged in the stand column; the cantilever is fixedly connected to the portion, higher than the top end of the stand column, of the rotating core shaft, and the movable trolley and the balance weight mechanism are arranged on the two sides of the cantilever; protruding edges which are arranged along the periphery of the stand column are arranged at the top end of the stand column, and the balance weight mechanism comprises a balance weight support fixedly connected with the cantilever and a balance weight shaft fixedly connected with the balance weight support; and a balance weight bearing capable of rolling along the lower surfaces of the protruding edges is connected to the balance weight shaft. The protruding edges and the balance weight bearing matched with the protruding edges are arranged, and counter-acting force borne by the balance weight mechanism is scientifically and reasonably transmitted to the stand column; due to the rolling manner, rotating friction force between the balance weight mechanism and the protruding edges is avoided; and the rotating crane is simple in structure, convenient to operate and lower in cost.
