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.
