BLADE REMOVING METHOD, BLADE MOUNTING METHOD AND SUSPENSION JIG
To provide a blade removing method, etc., capable of safely and promptly removing a blade of such a large-sized windmill that cannot be reached by a crane.SOLUTION: A front end of a blade which is a suspension object is directed downward, and a first suspension instrument is mounted to a blade which is not the suspension object. In a state where the first suspension instrument and the blade which is the suspension object are connected, the blade which is the suspension object is removed from a hub. A second suspension instrument is installed inside of the hub and in a state where the second suspension instrument and the blade which is the suspension object are connected, the first suspension instrument and the blade which is the suspension object are disconnected, The blade which is the suspension object is suspended by the second suspension instrument.SELECTED DRAWING: Figure 3
【課題】クレーンが届かないような大型の風車のブレードを安全且つ迅速に取り外すことができるブレードの取り外し方法等を提供する。【解決手段】吊り下ろし対象であるブレードの先端を下方に向け、吊り下ろし対象でないブレードに第１吊り器具を取り付け、第１吊り器具と吊り下ろし対象であるブレードを接続した状態で吊り下ろし対象であるブレードをハブから取り外し、ハブの内部に第２吊り器具を設置し、第２吊り器具と吊り下ろし対象であるブレードを接続した状態で第１吊り器具と吊り下ろし対象であるブレードの接続を解除して、第２吊り器具により吊り下ろし対象であるブレードを吊り下ろす。【選択図】図３
