Self-climbing crane

The invention relates to the field of lifting devices, and in particular to a self-climbing crane. The self-climbing crane comprises a self-climbing device and a lifting device fixedly assembled on the self-climbing device. The self-climbing device comprises two or more holding arm assemblies. The crane further comprises a guide rod and a guide sleeve which are sleeved together in an inserted manner and are in guide coordination. The guide rod and the guide sleeve are each provided with at least one holding arm assembly, and a telescopic driving device is arranged between the guide sleeve and the guide rod. When the self-climbing crane is used, the holding arm assemblies on the guide rod and the guide sleeve can work alternately to stabilize devices to corresponding vertical rods; the guide rod and the guide sleeve are lifted alternately through the telescopic driving device to achieve the climbing purpose so that automatic climbing can be achieved; and in addition, mutual guiding between the single guide rod and the guide sleeve is more smooth, and the problems of clamping and deforming can be more not likely to happen. Thus, the problems that an existing climbing type wind power equipment overhauling crane is likely to be abraded and poor in reliability are solved.
