Abstract
A tool to enable removal of a wind turbine blade, wherein the weight of the blade itself secures the blade without need for additional fixation. The tool includes an articulated structure, composed of an upper part and a lower part articulated to each other; a cradle-shaped support attached to the lower part of the structure and configured to house a blade, the cradle-shaped support having two portions being moveable to each other; a hooking element which allows the tool to be suspended from a first crane; and springs fixed to the structure for exerting an aperture force on the structure, which allows automatic aperture of the structure in the absence of blades in the interior of the cradle.
