The invention relates to a lifting appliance for lifting a frame. The lifting appliance comprises a lifting mechanism and a clamping mechanism, the hoisting mechanism comprises a hoisting ring, a hoisting chain, a bow-shaped shackle and a butterfly shackle; the clamping mechanism is composed of T-shaped upper pressing plates, L-shaped lower pressing plates and a rectangular hollow adjusting pipe, the upper pressing plates are arranged at the left end and the right end of the adjusting pipe, corresponding adjusting holes are formed in the connecting ends of the adjusting pipe and the upper pressing plates, adjusting pins penetrate through the adjusting holes to connect the adjusting pipe with the upper pressing plates, and the lower portions of the lower pressing plates penetrate through the front portions of the upper pressing plates. The longitudinal side part is connected with the upper pressing plate through a rotating shaft, so that the upper pressing plate can rotate around the shaft, the upper part of the upper pressing plate is connected with the lower part of the lifting chain through a bow-shaped shackle and a butterfly shackle, and the lifting ring is connected with the upper part of the lifting chain through the bow-shaped shackle and the butterfly shackle; the adjusting pipe can be transversely adjusted to adapt to lifting of vehicle frames with different widths; clamping force can be formed between the lower pressing plate in a special shape and the upper pressing plate, frames with different thicknesses can be hoisted, and the hoisting mechanism and the clamping mechanism are connected in a segmented mode so that the hoisting mechanism and the clamping mechanism can be independently replaced and maintained.
