The invention discloses an externally-hung climbing frame type self-climbing crane attached to a barrel wall and a climbing method.The self-climbing crane comprises a draught fan unit and a crane, the draught fan unit comprises a tower barrel composed of tower barrel sections, and the crane comprises a tower body, a climbing device, a climbing frame structure and a climbing frame dismounting device; the climbing frame structure is fixed outside the tower drum through a pin shaft; the crane is arranged on the tower body, climbs and descends along the climbing frame structure through the climbing device and climbs along the tower barrel section along with the increase of the height, the tower barrel, a cabin, a hub and blades of the whole large fan unit are installed in place, after installation in place, the crane descends along the tower barrel section, and the climbing frame structure is dismantled through the crane. And repeating the process to complete the installation of a whole set of wind turbine generator. The device has the advantages of small component size, small number, compact structure and light weight; transportation is convenient, and transition is easy; the occupied area is small, and dismounting is convenient; the hoisting is safe, the wind load influence is small, and the stability is good.
