The invention discloses a special lifting appliance for lifting a frame-shaped piece. The special lifting appliance comprises fixing pieces and connecting pieces, wherein the fixing pieces comprise fixing blocks and limiting blocks; the fixing blocks are of L-shaped structures; the limiting blocks are of circular-arc-shaped structures; the circle centers of the limiting blocks are arranged at theouter corners of the fixing blocks; the four fixing blocks are sequentially connected end to end through the connecting pieces; and the two connecting pieces are arranged on the fixing blocks in parallel. The lifting appliance for lifting the frame-shaped piece is formed through cooperation of the fixing pieces and the connecting pieces, and the frame-shaped piece is lifted through cooperative useof four lifting appliances; and due to the fact that the fixing pieces are provided with arc-shaped grooves, a steel wire rope for lifting is convenient to embed, the steel wire rope and the fixing pieces are tightly fixed, fixing and dismounting are convenient, and the hoisting and transferring efficiency is improved.
