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: A direct-drive wind turbine comprises a wind turbine rotor and a generator mounted on a frame. The wind turbine rotor comprises a hub carrying blades and the generator comprises a generator stator comprising a track structure and a stator surface connected to the track structure, wherein the stator surface has coil windings, and carriages connected one after the other and adapted to run on the track structure, wherein the carriages carry an electrically magnetically active material facing the stator surface such that when the carriages run along the track structure a magnetic field is generated across an air gap provided between the carriages active materials and the stator coil windings, wherein one or more carriages are directly coupled to the wind turbine rotor by rigid connectors such that rotation of the wind turbine rotor causes displacement of the carriages along the track.
