Zusammenfassung:	There is provided a lifting unit for lifting a rotor of a wind power installation. The lifting unit has at least one first sling for looping around a region of a rotor blade on a rotor of the wind power installation, which region is near the rotor blade root, at least one transverse strut, at least one first and second strut or sling portion, and at least one first and second hinge unit. The at least one first and second struts or sling portions extend between the at least one first and second hinge units and the transverse strut. The lifting unit further has at least one second sling having first and second sling portions and a strut. The first ends of the first and second sling portions are fixed to the first and second hinge units. The second sling is adapted to be arranged around a rotor blade stub.
