Abstract

La présente invention concerne un système (100) destiné à commander le montage d'un composant (120) d'une éolienne sur un cadre de montage (130), le composant (120) pouvant être monté sur le cadre de montage (130) par l'intermédiaire d'une attache (110). Le système (100) comprend un mécanisme de déplacement d'attache. Le mécanisme de déplacement d'attache est conçu pour déplacer l'attache (110) entre une position ouverte pour positionner le composant (120) dans le cadre de montage (130) et une position fermée dans laquelle l'attache (110) est enroulée au moins partiellement autour du composant (120) afin de fixer le composant (120) au cadre de montage (130).
