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.

Abstract: A method for handling a wind turbine component (20) is disclosed. The method includes providing a lifting system including a hoist cable (36) and an attachment assembly (38). The attachment assembly includes one or more removable ballast weights (48). The method includes positioning the attachment assembly near a working surface, removing at least some of the one or more ballast weights from the attachment assembly, and attaching a lifting tool (34) to the attachment assembly. The combined weight of the attachment assembly and the lifting tool is sufficiently greater than a threshold weight of the lifting system. The method further includes attaching a wind turbine component to the lifting tool and moving the wind turbine component using the lifting system. A lifting system is also disclosed. The lifting system includes a hoist cable, an attachment assembly, and a lifting tool. The combined weight of the attachment assembly and the lifting tool is sufficiently greater than a threshold weight of the lifting system.
