CA 2666553

A method of replacing a wind wheel facility can reduce costs required to replace a large-sized facility in a nacelle. The method includes a winch lifting step (S1) that, by using a permanent winch that is provided on a girder moving in the nacelle placed on a column, lifts up to the nacelle both a reciprocating winch used to replace a wind wheel facility, which is placed in the nacelle, and a balance for supporting the wind wheel facility; a wire lifting step (S2) that lifts a wire used to replace the wind wheel facility up to the nacelle from a drum placed on the ground; a winch replacement step (S3) for removing the permanent winch from the girder and mounting a replacement winch on the girder; and a wire placement step (S4) for passing the lifted wire over the reciprocating winch and a moving pulley that is provided between the balance and the girder.

L'invention concerne un procédé de remplacement d'une installation de roue éolienne qui peut réduire les coûts de remplacement d'une installation de grande dimension dans une nacelle. Le procédé consiste à (S1) à soulever un treuil : au moyen d'un treuil permanent disposé sur une poutre se déplaçant dans la nacelle placée sur une colonne, soulever jusqu'à la nacelle un treuil alternatif utilisé pour remplacer une installation de roue éolienne placée dans la nacelle et un contrepoids pour supporter l'installation de roue éolienne ; (S2) à lever un câble : lever un câble utilisé pour remplacer l'installation de roue éolienne jusqu'à la nacelle à partir d'un tambour placé sur le sol ; (S3) remplacer le treuil : retirer le treuil permanent de la poutre et monter un treuil de remplacement sur la poutre ; (S4) placer un câble : faire passer le câble levé au-dessus du treuil alternatif et d'une poulie mobile disposée entre le contrepoids et la poutre.
