Beschreibung
Zusammenfassung:	The invention provides a high-altitude multi-layer annular steel structure tower crane, and belongs to the field of tower cranes, the high-altitude multi-layer annular steel structure tower crane comprises a base, a push plate, a first rotating plate, a movable plate, a transmission block and a foot stool, the bottom of the base is provided with a hydraulic rod for driving the push plate to ascend and descend along the base; the surface of the push plate is rotationally connected with a connecting plate for driving the first rotating plate to rotate, and the surface of the first rotating plate is fixedly connected with a transmission plate for driving the movable plate to swing; according to the high-altitude multi-layer annular steel structure tower crane, the driving plate is arranged, and the driving plate is obliquely arranged relative to the driven plate, so that when the driving plate is subjected to upward pulling force from the mounting block, pulling force can be applied to the driven plate, and the
