The invention discloses a novel lifting device used for a large ring forged piece. The novel lifting device comprises a strong ring, chains, lifting rings, bow shackles and butterfly buckles. The lifting rings are connected with the bow shackles. One end of each lifting ring is connected with the corresponding chain through the corresponding butterfly buckle connected with the corresponding bow shackle, and then connected with the strong ring; the other end of each lifting ring is connected with the corresponding chain through the corresponding butterfly buckle connected with the corresponding bow shackle, and then connected with a corresponding lifting hook. In this way, the novel lifting device used for the large ring forged piece is low in investment cost, high in operation efficiency, wide in application scope and convenient to disassemble. Various ring forged pieces with different models can be lifted under the circumstances of the limited distance between a crane and the ground. When the large ring forged piece is lifted by the novel lifting device, expansion angles of the chains are small; the torque in the radial direction is small, and most of the torque is distributed to the vertical direction; in this way, the lifting hooks are safer and firmer to use.
