System, device and method for lifting and controlling the horizontal orientation and/or position of components

A method of lifting and controlling the horizontal orientation and/or position of a wind turbine component, during installation and/or dismounting of said components, by means of a lifting device (10), wherein the lifting device comprises:

• a crane connection arrangement (11) to be connected to one or more lifting lines (3a) of a crane arrangement,
• a frame arrangement (12) connected to said crane connection arrangement (11), a first and a second steering wire guide (13a, 13b) for guiding steering wires (20a, 20b) placed on the crane arrangement (11), and
• a component connection arrangement (30) connected to said frame arrangement and configured to be connected directly or indirectly to the component, wherein a guiding arrangement (4) is connected to a crane boom arrangement (3), and wherein said steering wires (20a, 20b) are connected to said guiding arrangement (4) and extend from the guiding arrangement (4) in a direction towards the lifting device (10) with a mutual angle (a1) between the steering wires (20a, 20b), and so that the steering wires (20a, 20b) are guided by said first and second steering wire guides (13a, 13b), wherein the method comprises the steps of:
• connecting one or more lifting lines (3a) to the crane connection arrangement (11) so that the lifting device (10) hangs from the one or more lifting lines (3a),
• connecting said component (90) to be lifted to said component connection arrangement (30),
• hoisting and/or lowering said component (90) by operating said one or more lifting lines (3a), and/or rotating (RO) the frame arrangement (12) in a horizontal plane by means of said one or more steering wires (20a, 20b) guided by the steering wire guides (13a, 13b),
• wherein a relative displacement between one or both of the first and second steering wire guides (13a, 13b) and said frame arrangement (12) is provided due to and/or in repose to a rotation (RO) of the frame arrangement (12) by a rotation control arrangement (15a, 15b), and/or wherein a relative displacement between one or both of the first and second steering wire guides (13a, 13b) and said frame arrangement (12) is provided in response to a change in distance (DIS1) between the lifting device (10) and the guiding arrangement (4), wherein—the first and second steering wire guide (13a, 13b) are connected to and supported by the frame arrangement (12).
