Embodiment Construction

[0036] figure 1 A crane structure 10 for assembling a wind power installation 100 is shown. The specific configuration of the crane structure 10, in particular the jib system 11, is not critical to the invention. The idea according to the invention can be applied in principle to every type of boom system 11 , for example in lattice cranes and telescopic boom cranes.

[0037]The yoke 30 is suspended on the lifting hook 20 through the suspension mechanism 21 . The yoke 30 comprises a frame, which gently and without damage lifts the rotor blade of the wind power installation 100 to be raised. Furthermore, the yoke 30 comprises a set of independently working components, such as winches, drives, operating mechanisms, which are also used for manipulating the payout control cables 40 .

[0038] These control cables 40 are indirectly connected to the boom system 11 for adjusting and stabilizing the yoke 30 . Contrary to the prior art, no additional guide cables are tensioned on th...

Abstract

The present invention relates to a crane comprising: a crampon indirectly / directly fixed on a lifting cable of the crane; and a frame which is hanged on the crampon and used for lifting a special cargo, especially used for lifting a rotor blade of a wind power device, wherein a control element of the frame hanged on the crampon guides along a guiding cable area of the lifting cable of the crane.

Description

technical field [0001] The invention relates to a crane with a lifting hook indirectly / directly fixed on the hoisting rope of the crane and a rotor suspended from the lifting hook for lifting special goods, in particular for lifting wind power installations Frame of leaves. Background technique [0002] When assembling a wind power plant, the rotor blades are installed at a high lifting height. Preferably, truck cranes or crawler cranes are used for this purpose. The rotor blade to be assembled has a large rotor surface and thus a large wind-acting surface. Sufficiently precise adjustment and stabilization of the lifted rotor blade at the mounting height is required for mounting the rotor blade on the corresponding wind power installation. [0003] It is already known from the prior art to lift rotor blades by means of frames. The frame is suspended from the lifting hook of the hoisting cable and lifts the rotor component to be assembled in the corresponding receptacle. ...
