The invention provides a lifting device of a tower crane hanging bracket and a lifting method of the tower crane hanging bracket. The lifting device comprises a rapid lifting mechanism and a hanging bracket leveling mechanism which are sequentially arranged from top to bottom. The rapid lifting mechanism comprises a middle platform, at least three groups of first lifting ropes which are uniformly distributed around the geometric outer contour of a to-be-lifted cargo, and first winch assemblies which are arranged on the cart and are in one-to-one correspondence with the first lifting ropes; the middle platform is horizontally arranged, the upper end of the first lifting rope is connected with the first winch assembly corresponding to the first lifting rope, and the lower end of the first lifting rope is connected with the middle platform; the lifting frame leveling mechanism comprises at least three groups of second lifting ropes which are uniformly distributed around the geometric outer contour of the goods to be lifted and second winding assemblies which are arranged on the middle platform and are in one-to-one correspondence with the second lifting ropes; the second winch assembly is driven by a servo motor, the upper end of the second lifting rope is connected with the second winch assembly corresponding to the second lifting rope, and the lower end of the second lifting rope is used for being connected with a lifting frame. The structure is simple, leveling is fast, and efficiency is high.
