Abstract: A rotor assembly for a wind turbine comprises a hub, a blade provided with a blade root portion and a strengthener for the blade root portion. The strengthener comprises a supporting part that strengthens the blade root portion and the supporting part comprises a supporting portion to temporarily support the blade. The supporting portion is made in one piece with the supporting part. The rotor assembly also comprises a number of first fasteners and second fasteners to fasten the blade root portion to the hub. The second fasteners are adapted to fasten the supporting part of the strengthener to the blade root portion when the latter is not fastened to the hub.

Abstract: The assembly includes a tool with a stem having a first end having a projecting portion such as a ring, and a second end adapted to be engaged by lifting equipment. The assembly also includes a stem receiving portion formed in a wind turbine part to be lifted. The stem of the tool is adapted to be freely passed through the stem receiving portion until the first end of the stem is locked to the stem receiving portion, thereby preventing the stem from separating from the stem receiving portion when lifting the wind turbine part.

Abstract: The safety structure comprises temporarily deployable safety bars that can be attached to a support member associated with at least one of a wind turbine hub, a wind turbine blade, a wind turbine root section, a wind turbine yaw mechanism, a wind turbine tower base, a wind turbine foundation, and a wind turbine nacelle. The bars can be coupled with each other and the structure may comprise at least one inflatable portion. The safety bars are first attached to the support member surrounding a wind turbine portion and then coupled to each other defining a fence structure.
