    Abstract: An alignment tool (1) for aligning a bore (13) extending through a first structural member (14) with a bore (19) extending through a second structural member (15) is disclosed. The alignment tool (1) comprises two shaft portions (2, 3) having a cylindrical or cylindrical like configuration. The second shaft portion (3) is arranged adjacent to the first shaft portion (2). A portion of the second surface forms a continuation of a portion of the first surface. A first bushing (8) is arranged along the first shaft portion (2) and substantially covering the first surface, and a second bushing (9) is arranged along the second shaft portion (3) and substantially covering the second surface. Mutual rotational movements are allowed between the first shaft portion (2) and the first bushing (8) and between the second shaft portion (3) and the second bushing (9).

    Abstract: A method of lifting a rotor of a wind turbine, the rotor having a center of gravity and including a hub and first, second, and third blades projecting outwardly from the hub at locations circumferentially distributed thereabout, includes positioning first and second slings around the first and second blades, respectively, to define first and second lifting zones delineating a lifting envelope, wherein the lifting envelope encompasses the center of gravity. The method also includes lifting the rotor above a surface via the first and second slings wherein the rotor is in one of a substantially horizontal or substantially vertical orientation, with the aid of at least one of the first and second slings while continuing to fully support the rotor by the first and second slings.
