Embodiment Construction

[0018] figure 1 An arrangement of a mobile crane 1 is shown for positioning and orienting a rotor blade 2 of a wind turbine relative to a hub (not shown) of the wind turbine.

[0019] The mobile crane 1 includes a boom 3 . A cable 4 hangs downwards from the end of the crane jib and a yoke 5 is connected to the cable 4 by a cable 6 . Further cables 7 hang downwards from each end of the yoke 5 , which cables 7 are arranged around and carry the rotor blade 2 . The positioning and orientation of the rotor blade 2 relative to the hub is done by adjusting the crane boom 3 and by moving the rotor blade 2 . Typically, several people are required to guide and control the movement of the rotor blade 2 by manually pulling on a cable (not shown) attached to the rotor blade 2 . Because the cables 4 carry the yoke 5 with one point of attachment and because the working surface of the rotor blade 2 is relatively large for the wind, especially in high wind conditions, it is difficult to po...

Abstract

The invention concerns a method for mounting of at least two components (30, 40) of a wind turbine with each other wherein the first component (30) is positioned, oriented and / or arranged relatively to the second component (40) by a Reach Stacker (10). The invention concerns moreover the use of a Reach Stacker (10) for mounting of at least two components (30, 40) of a wind turbine with each other wherein the first component (30) is positioned, oriented and / or arranged relatively to the second component (40) by the Reach Stacker (10).

Description

technical field [0001] The invention relates to a method for mounting at least two components of a wind turbine to each other. The invention also relates to the use of a handling device for installing at least two components of a wind turbine. Background technique [0002] A wind turbine consists of several components such as a tower, nacelle, generator, rotor including hub and rotor blades, etc. In order to build a wind turbine, these partially very heavy parts have to be mounted on top of each other. When installing on the ground, a mobile crane is typically used to position, orient and arrange the components that can be mounted together relative to each other. [0003] Such a mobile crane, which usually includes a boom, is used, for example, to position and orient the rotor blades relative to the hub. A cable hangs down from the end of the crane boom to which the yoke is attached. Other cables hang down from each end of the yoke, which cables are arranged around and c...
