ROTOR TURNING LIFTING YOKE

Rotor lifting yoke for lifting a three bladed rotor (6), said rotor lifting yoke comprising: a lifting structure (16), a first (34) and second flexible elongated element (36) arranged to be connected both to the lifting structure and to a root portion (104) of a first blade (10a) of the rotor, and a third (38) and fourth flexible elongated element (40) arranged to be connected both to the lifting structure and to a root portion of a second blade (10b) of the rotor. The rotor lifting yoke further comprises one or more length adjusting mechanisms (44, 46) which are arranged to adjust the effective length of the first and third and/or the second and fourth flexible elongated elements. The flexible elongated members are further arranged such that when said flexible elongated members are attached to the root portions of their respective blades, at least one point on the first and third and/or at least one point on the second and fourth flexible elongated elements is attached to their respective blades via a non-slip attachment. In this way, a rotor lifting yoke is provided which can rotate the rotor from a vertical to a horizontal position and back again in an easy and flexible manner just by adjusting the lengths of the flexible elongated members.
