Abstract: 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.

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 translation: 该组件包括具有杆的工具，其具有第一端，其具有诸如环的突出部分，以及适于通过提升设备接合的第二端。 组件还包括形成在要提升的风力涡轮机部分中的杆接收部分。 工具的杆适于自由地通过杆接收部分，直到杆的第一端被锁定到杆接收部分，从而防止当提升风力涡轮机部分时杆从杆接收部分分离。
