The invention discloses a transfer lifting appliance for nuclear fuel related assemblies. The transfer lifting appliance comprises a lifting ring, a cotter pin, a pin shaft, a lifting hook and a tongue piece. The lifting hook is connected with the lifting ring through the pin shaft. The tongue piece is fixed to the lifting hook through a bolt. The lifting hook and the lifting ring are connected together through the pin shaft. The cotter pin is inserted into the pin shaft and used in cooperation with the pin shaft. The transfer lifting appliance has the beneficial effects that (1) the related assemblies are safely and stably lifted into/out of a suspension platform, and quick unhooking is achieved; (2) no damage (including scratches) is generated in the process that the related assemblies are lifted into/out of the suspension platform; (3) the multiple related assemblies can be lifted through the same lifting appliance; (4) the transfer efficiency of the related assemblies is improved by five times; (5) no lifting rope needs to be manually used, and safety is guaranteed; and (6) the split structure is adopted, and universality and replaceability are higher.
