The invention discloses a crane and a method for establishing a super-lifting device on the crane. The crane comprises a main arm (20), a rotary table (10), an auxiliary lifting winch (30) and an auxiliary lifting steel wire rope (40). The crane is characterized in that the main arm (20) and the auxiliary lifting winch (30) are installed on the rotary table (10), the first end of the auxiliary lifting steel wire rope (40) is wound around the auxiliary lifting winch (30), the second end of the auxiliary lifting steel wire rope (40) is connected to a top-joint arm (21) of the main arm (20), and therefore the super-lifting device of the crane is composed of the auxiliary lifting winch (30), the auxiliary lifting steel wire rope (40) and the rotary table (10). By the adoption of the technical scheme, a specific super-lifting device does not need to be additionally arranged on the crane, the super-lifting function can be achieved through existing components on the crane, the number of parts of the crane is reduced, multiple purposes are achieved through the crane, and the production cost is remarkably reduced.
