The invention relates to the field of buildings, in particular to a lifting appliance and lifting method for a prefabricated inspection well. An end structure is a pincer-like portal frame, and the pincer-like portal frame is of a right-angle n-shaped structure. A middle gap is formed in one side of the right-angle n-shaped structure. The right-angle n-shaped structure further is further providedwith a locking plate. The right-angle n-shaped structure is provided with a pincer-like portal frame hole and further provided with the locking plate which is disposed by penetrating through the middle gap. The locking plate is similar to a triangle, the top end of the locking plate is provided with a lifting hole, one side of the locking plate is provided with a penetrating hole, and a rotary supporting shaft nail can penetrate through the pincer-like portal frame hole and the penetrating hole and then be fixed with a nut. The portion, facing the interior of the right-angle n-shaped structure, of the locking plate is provided with an extrusion piece, and one vertical side of the right-angle n-shaped structure is provided with an outer side extrusion piece. The lifting appliance is convenient to disassemble, use and assemble, beneficial for lifting, stable and large in bearing capacity.
