A system for assembling/disassembling a blade in the rotating hub of a windmill is described, which system includes a set of structural components including: a hoisting structure capable of joining the tower and providing an element to support the load, with a variable geometry to adapt to the changes of diameter of the tower; a main structure that moves along the extension of the tower, provided with lifting points, also movable to control the position in the horizontal level; a clamp structure to grasp the blade and facilitate the subsequent change in the orientation of the blade; and means for lifting the main structure made up by traction cables attached at one end to the hoisting structure and at the other end to respective capstans which are external to the structure and located at ground level.
