The invention discloses a tail lifting appliance for lifting a prefabricated pier body and a construction method of the tail lifting appliance. The tail lifting appliance is matched with a head lifting appliance through a lifting mechanism and used for lifting the prefabricated pier body. The tail lifting appliance comprises a pair of oppositely arranged clamping devices and a top connecting mechanism. Two cross beams are transversely arranged between the pair of clamping devices in a spaced manner, a square clamping groove is defined by the two cross beams and the pair of clamping devices together and used for containing and clamping the prefabricated pier body, and the lengths of the clamping devices can be adjusted so that the space of the clamping groove can be adjusted. The top connecting mechanism is connected to the clamping devices, and the tops of the clamping devices are hinged to the top connecting mechanism, so that the clamping devices can horizontally rotate in the opening direction of the clamping groove in a hinged mode. The tail lifting appliance has the technical effects that after the pier body is lifted, the pier body is vertically released, oblique pulling and oblique lifting of a hoisting crown block are avoided, the structure is stable, and the construction efficiency is high. The tail lifting appliance for lifting the prefabricated pier body and the construction method of the tail lifting appliance can be widely applied to the technical field of prefabricated pier body lifting devices.
