Embodiment Construction

[0028] figure 1 A part of a lifting trolley 1 of the invention is shown, comprising a lifting device 2 with several cables 3 to which connecting means 4 are attached, as is known.

[0029] A lifting device 5 (often also called a yoke) of the invention is attached to the connection device 4 . see figure 2 and 3 , the lifting device 5 comprises a frame 6 with two upright-ended support arms 7, which here have a C-shape.

[0030] The lifting device 6 carries the component, here the rotor blade 8 . The C-shaped support arm 7 is equipped with a corresponding holding device 9 for holding or clamping the rotor blade 8 .

[0031] The rotor blades 8 are arranged in the horizontal direction and are lifted to be attached to figure 1 A mounting interface 10 of a hub 11 of a wind turbine 12 is shown. Therefore, the blade root 13 connected to the airfoil-shaped blade body 14 must be precisely positioned relative to the mounting interface 10 . This lifting and positioning is sometimes...

Abstract

A lifting apparatus for a lifting crane (1), adapted to carry an elongated component having a non-circular cross section extending over the major part of its length, especially a rotor blade (8) of a wind turbine (12), comprising a frame (6) with at least one holding means (9) for holding the component with a horizontal orientation, wherein a pitching system (17) for pitching the component around its longitudinal axis is provided.

Description

technical field [0001] The present invention relates to a lifting device for a lifting crane, suitable for carrying an elongated part, in particular a rotor blade of a wind turbine, having a non-circular cross-section extending over a substantial part of its length, The lifting device includes a frame with at least one holding device for holding the component in a substantially horizontal orientation. Background technique [0002] Large and slender components are usually moved by a hoisting crane adapted to lift and position the respective component for attaching it to, for example, a building. An example of such a component is a rotor blade of a wind turbine, which needs to be positioned and fixed to the hub of the wind turbine when the wind turbine is installed, typically three rotor blades are attached to the hub. In order to lift such a component, respectively the rotor blade, special lifting equipment is used, which is connected to a lifting crane and which is suitable...
