The invention relates to the technical field of water conservancy construction engineering, in particular to a gravity type square wharf prefabricated square hoisting device and a mounting method.The hoisting beam comprises an upper beam, a rotary supporting structure and a lower beam, and the upper beam is connected with the lower beam through the rotary supporting structure; the rotary supporting structure and the lower beam are sequentially located below the upper beam and are linearly arranged along the central axis of the upper beam. Two transmission assemblies are slidably connected into the lower beam and located on the two sides of the supporting structure. The device has the advantages that angle alignment between prefabricated concrete square blocks is guaranteed, the hydraulic telescopic arm pushes the rear square block to move in the direction aligned with the front square block, alignment is guaranteed through the push arm cross rod, the underwater mounting stability of the prefabricated square b
