Abstract[English]
A method is provided of handling a wind turbine blade (20) of a wind turbine (10). The wind turbine (10) includes a tower (12) and a nacelle (14) connected to the tower (12) with the wind turbine blade (20) being configured to be rotatably attached to the nacelle (14). The method includes providing a first crane (38) supported from the nacelle (14) and including a first attachment structure (70) and a second crane (78) including a second attachment structure (92). The method includes attaching the first attachment structure (70) to the wind turbine blade (20) and the second attachment structure (92) to the wind turbine blade (20). The method further includes operating the nacelle (14) or the first crane (38) and the second crane (78) to arrange the wind turbine blade (20) in an oblique angular position and attaching or detaching the wind turbine blade (20) respectively to or from the nacelle (14) while the wind turbine blade (20) is arranged in the oblique angular position.[French]
L'invention concerne un procédé de manipulation d'une pale d'éolienne (20) d'une éolienne (10). L'éolienne (10) comprend une tour (12) et une nacelle (14) reliée à la tour (12), la pale d'éolienne (20) étant conçue pour être fixée rotative à la nacelle (14). Le procédé comprend la fourniture d'une première grue (38) supportée à partir de la nacelle (14) et comprenant une première structure de fixation (70) et une seconde grue (78) comprenant une seconde structure de fixation (92). Le procédé comprend la fixation de la première structure de fixation (70) à la pale d'éolienne (20) et de la seconde structure de fixation (92) à la pale d'éolienne (20). Le procédé comprend en outre l'actionnement de la nacelle (14) ou de la première grue (38) et de la seconde grue (78) pour agencer la pale d'éolienne (20) dans une position angulaire oblique et la fixation ou le détachement de la pale d'éolienne (20) respectivement vers ou à partir de la nacelle (14) pendant que la pale d'éolienne (20) est disposée dans la position angulaire oblique.
