Zusammenfassung:A method of lifting a nacelle installed on a tower is provided. The method includes attaching a tapered bushing mechanism to a through-hole provided for a member of the tower; attaching a push-up bolt to the tapered bushing mechanism; and raising the push-up bolt while pushing the push-up bolt against a first member provided for the nacelle. The tapered bushing mechanism includes a tapered bushing inner cylinder and a tapered bushing outer cylinder. The tapered bushing inner cylinder includes a first taper section whose outer diameter becomes larger toward an end of the tapered bushing inner cylinder and a first screw thread formed on an inner surface of the tapered bushing inner cylinder. The tapered bushing outer cylinder includes a second taper section whose inner diameter becomes smaller toward an end of the tapered bushing outer cylinder.
