Abstract
A method for handling a load (2) including a wind turbine component (202). The method includes, while a crane (1) is supported by a supporting element (G), arranging a control arrangement (501, 502), which is at least partly elongated and flexible, so as to extend, while the load (2) is lifted in a suspended manner with the crane (1), from the load (2) to an actuator (511, 512), located on the supporting element (G), at a distance from the crane (1). The actuator (511, 512) controls the orientation of the load (2) by the control arrangement (501, 502), and the control arrangement (501, 502) is extended, during the load orientation control, via a redirection device (531, 532) which is connected to the supporting element (G).
Claims6
A method for handling a load comprising a wind turbine component, comprising,
- while a crane is supported by a supporting element, arranging a control arrangement, which is at least partly elongated and flexible, so as to extend, while the load is lifted in a suspended manner with the crane, from the load to an actuator,
- the actuator controlling the orientation of the load by means of the control arrangement,
- characterised by
- the control arrangement being extended, during the load orientation control, via a redirection device which is connected to the supporting element,
- wherein the redirection device is located on the crane,
- wherein the actuator is located at a distance from the redirection device and at a distance from the crane,
- wherein the control arrangement comprises a gear arrangement, wherein the gear arrangement comprises a rope and pulley system, wherein the redirection device forms a pulley in the rope and pulley system,
- the gear arrangement comprising a winch, the winch being located on the crane, the redirection device being located, along the control arrangement, between the winch and the load.
