Abstract[English]
The invention provides a method for handling a wind turbine rotor blade (11) of a horizontal axis wind turbine (1), which wind turbine comprises a tower (14) supported by and fixed to a foundation (17), a nacelle (15) on the tower, and a rotor hub (18) rotatably mounted to the nacelle, the method comprising - fixedly mounting a blade supporting device (21a, 21b) to the foundation and/or to the wind turbine, - lifting the blade to the hub, or lowering the blade from the hub, and - positioning the blade on the blade supporting device (21a, 21b) so as to be supported by the blade supporting device, before the blade is lifted to the hub, or upon lowering the blade from the hub.[French]
L'invention concerne un procédé de manipulation d'une pale de rotor d'éolienne (11) d'une éolienne à axe horizontal (1) ; ladite éolienne comprend une tour (14) supportée par et fixée à une fondation (17), une nacelle (15) sur la tour, et un moyeu de rotor (18) monté rotatif sur la nacelle ; le procédé comprend le montage fixe d'un dispositif de support de pale (21a, 21b) sur la fondation et/ou sur l'éolienne, le levage de la pale vers le moyeu, ou l'abaissement de la pale à partir du moyeu, et le positionnement de la pale sur le dispositif de support de pale (21a, 21b) de manière à être supportée par le dispositif de support de pale, avant que la pale ne soit soulevée au moyeu, ou lors de l'abaissement de la pale à partir du moyeu.
