Abstract: A lifting apparatus (10) for a wind turbine blade (2), said apparatus comprising a cradle (12) for carrying a said blade, and a lifting yoke (14) which is cooperable with a crane, in use, to lift the cradle. The lifting yoke is mounted to the cradle and is moveable in a lengthwise direction relative to the cradle to permit adjustment of the orientation of the cradle when the yoke is suspended from a lifting point associated therewith. Said apparatus is particularly relevant for lifting and manoeuvring wind turbine blades which are particularly large and heavy and difficult to move between sites. It is one benefit of the invention that the orientation of the blade when carried in the cradle can be controlled conveniently, safely and reliably by adjusting the position of the yoke relative to the cradle.
