Abstract: An equipment for installing and dismantling of a wind turbine system including a tower, a nacelle and a blades is capable of self-climbing along the tower via upper and lower grippers moving up and down the supporting frame equipped with two booms along the tower. The two booms aren't able to turn around in horizontal plan but are able to hoist, for example, the nacelle and pivot it to the top of the tower before placing it on the positioning frame. In order to combine the nacelle to the tower, the nacelle resting on the positioning frame shall be adjusted to the location of the tower in horizontal plan before the positioning frame is lowering it to the tower.
