The invention discloses a method for hoisting an object of an asymmetrical structure. The method comprises the steps that (1), the position of the geometric center line and the position of the actual gravity center line of the object of the asymmetrical structure and the offset direction and offset distance of the actual gravity center line relative to the geometric center line are calculated and determined; (2), a cantilever crane which is fixed to a hoisting platform based on the determined geometric center line in advance and used for hoisting the object of the asymmetrical structure is moved by the offset distance in the offset direction, so that the hoisting gravity center line of the cantilever crane and the determined geometric center line coincide; (3), a special hoisting tool which is suspended along the hoisting gravity center line of the cantilever crane and used for hoisting the object of the asymmetrical structure is provided so that the object of the asymmetrical structure can be kept balanced when hoisted; (4), the special hoisting tool is fixedly connected with the object of the asymmetrical structure, and then hoisting operation is conducted, so that the object of the asymmetrical structure is kept balanced when hoisted.
