The invention relates to the field of construction machinery, in particular to a multi-level adjusting type rotary construction crane. The crane comprises a base; a supporting column is installed on the base; a horizontal rotating seat is installed at the top of the supporting column; a hanging bracket is installed on the horizontal rotating seat; a side supporting frame is installed on the hanging bracket; a load bearing base seat is installed on the side supporting frame; side wing frames are installed on the load bearing base seat; a transmission cavity is arranged on the load bearing baseseat; a folded connecting rod is installed in the transmission cavity; swaying frames are installed at the outer ends of the side wind frames; vertical rotating seats are installed on the swaying frames; limiting frames are installed at the driving ends of the vertical rotating seats; movable plates are installed inside the limiting frames; a plurality of driving gears are installed on the limiting frames in a built-in mode; toothed bars are arranged on the lower plate surfaces of the movable plates; the driving gears are engaged with the toothed bars; and suspension brackets are installed attwo plate ends of the movable plates. According to the crane, degree of freedom in three-dimensional adjustment can be realized with the hanging bracket being the central line, and position of the hanging bracket can be adjusted on the track of material throwing.
