The invention discloses a self-unloading large annular forge piece lifting tool which consists of a lifting control part and a suspension control part. A guide sleeve is operated to lift to drive a fixture block to move up and down to be contacted with different diameter parts of a reducing rod, so that the fixture block rotates to a different extent, and therefore, suspending and lifting movements of the lifting tool are realized, the lifting tool and an annular piece under the intervention of external force are automatically separated. The lifting tool is simple in structure, convenient to operate, safe and reliable and has a using value for increasing the running speed and improving the production efficiency of the large annular forge piece.
