Device and method for mounting and dismantling a component of a wind turbine

A wind energy turbine with a tower and a tower head and at least one fastening means on a tower head for a guide means of an apparatus for mounting and/or dismantling a component having a root area and a tip area of a wind turbine with a tower head, the apparatus comprises at least one guide means that can be tensioned between the tower head and the ground, on which at least one holding apparatus can be arranged that carries at least a partial load of a weight of the component during a transport of the component between the ground and the wind turbine, and wherein a loading cable runs from at least one loading apparatus to the root area and a length of the loading cable can be varied between the loading apparatus and the root area and wherein the at least one loading apparatus is arranged in an area of the tower head and is adapted to hold at least one further partial load of the component during a transport of the component between the ground and the wind turbine and in which at least one holding cable runs from the holding apparatus to the tip area whose length can be varied between the holding apparatus and the component wherein the positions of the root area and the tip area are controllable by the respective holding cable and loading cable such that at least in a ground area the component is moved vertically with respect to the ground given a substantially parallel alignment of a longitudinal direction of the component to the ground and the component is then rotated about a transversal axis and positioned vertically under the tower head.

A process for mounting and/or dismantling a component having a root area and a tip area from a wind energy turbine having a tower and a tower head, the apparatus comprises at least one guide means is tensioned between the tower head and the ground, and on which guide means a holding apparatus is arranged, that is adapted to hold a partial load of the weight of the component during a transport of the component between the ground and the wind turbine, and wherein a loading cable runs from at least one loading apparatus to the root area and a length of the loading cable can be varied between the at least one loading apparatus and the root area, comprising the steps of

• fastening the component to a holding cable, that runs from the holding apparatus to the tip area and the holding cable has a length that varies between the holding apparatus and the component,
• controlling the positions of the root area and the tip area by the respective holding cable and loading cable,
• moving the component substantially vertical with respect to the ground in an area of the ground given a substantially parallel alignment of a longitudinal direction of the component to the ground,
• rotating the component about a transversal axis, and
• positioning the component vertically under the tower head.
