A bolted attachment having opposite threaded sections between which a shank is provided having at least two shank sections with different diameter located at a length from the threaded section of at least three times the difference between a diameter of a threaded section and a minimum diameter of the shank. At least one conical transition is formed between two adjacent shank sections where the ratio of its length to a difference between a diameter at one end of the transition and a diameter at the opposite end of the transition is of at least 0.85.

Bolted attachment for attaching wind turbine parts

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.
