The phenomena that when rolled metal is lifted through an existingknown travelling crane lifting hook by hanging a steel wire rope or chain in a manual hanging or unloading manner, the labor intensity of workers is high, the dangerousness is large, and the working environment of the workers is poor are changed, and the gravity type self-unloading lifting hook is especially suitable for high-labor intensity, poor-environment and high-dangerousness lifting operation that special-steel slow cooling materials are fed into an insulating pit. The lifting hook is suitable for new rod production line rolled piece lifting and old rod production line rolled piece lifting, the structure is sim |
