The invention belongs to the technical field of lifting of a spent fuel transfer container of a million-kilowatt nuclear power station, and particularly relates to a lifting device for the spent fueltransfer container of the million-kilowatt nuclear power station. According to the lifting device for the spent fuel transfer container of the million-kilowatt nuclear power station, a lifting beam, pneumatic components and lifting arms are arranged, and each pneumatic component is connected with the corresponding lifting arm and can drive the corresponding lifting arm to realize longitudinal reciprocating motion, so that when the spent fuel transfer container arranged in a water pool needs to be transferred, each lifting hook is firstly lowered until being parallel to a corresponding liftinglug, and then the lifting hook of each lifting arm is inserted into the corresponding lifting lug through rotating each lifting arm at a small angle; in the actual use process, frequent disassembly ofa lifting appliance for adapting to different container interfaces on site is reduced, the integral lifting time is shortened, the workload and the probability of manual operation errors are reduced,and the efficiency and the safety are improved; and meanwhile, abrasion of the lifting device for the spent fuel transfer container of the million-kilowatt nuclear power station caused by long-term frequent disassembly and replacement is avoided, and the service life is prolonged.
