Embodiment Construction

[0039] figure 1 is a simplified perspective view showing the elevator 2 according to the first embodiment of the present invention. figure 1 A situation is shown in which the elevator 2 is about to grab a rotor blade 4 of a wind turbine. The elevator 2 comprises first means 6 and second means 8 for contacting the outer surface of the rotor blade 4 . The outer surface of the rotor blade 4 is mainly indicated by the pressure side and the suction side. Both the first device 6 and the second device 8 carry a plurality of pads (not shown) in order to support the rotor blade 4 in the predetermined gripping area. Although the means 6 , 8 for contacting the outer surface of the rotor blade 4 can be configured with different design criteria depending on the embodiment of the elevator with grabbing jaws. The first means 6 for contacting the outer surface of the rotor blade 4 are first gripping jaws 6 . The second means 8 for contacting the outer surface of the rotor blade 4 are seco...

Abstract

A lift (2) for handling a rotor blade (4), a method of operating the lift (2) and a system comprising the lift (2) and the rotor blade (4) are provided. The lifter comprises at least one device, in particular grabbing jaws (6) for contacting the outer surface of the rotor blade. The elevator may further comprise a non-optical wave based system to detect the position of the rotor blade (4) relative to the elevator (2).

Description

technical field [0001] The invention relates to an elevator for handling rotor blades of a wind turbine, a system comprising an elevator and a rotor blade and further to a method of operating an elevator. Background technique [0002] The rotor blades of wind turbines (also known as wind power plants or wind energy converters) are generally hollow structures with a plurality of structural strengthening members arranged within the rotor blades. The outer surface of the rotor blade, which manifests mainly as the pressure side and the suction side, is not fully supported by the structural stiffeners inside the rotor blade. Therefore, the rotor blades of a wind turbine must be handled carefully in order to prevent the risk of damaging the rotor blades even under their own weight. In particular, during mounting of the rotor blade on the rotor hub of a wind turbine, the rotor blade must be gripped within a predetermined gripping area designated to support the weight of the rotor ...
