发明名称 METHOD OF LIFTING A WIND TURBINE NACELLE
摘要 This invention relates to a method of lifting a wind turbine nacelle (1), the method comprising: arranging a first and second anchoring point (2,3) on each of two opposing sides of the nacelle (1), the first point (2) of each side being arranged below the centre of gravity (4) of the nacelle (1) and the second point (3) of each side being arranged above the centre of gravity (4), wherein one of said first and second anchoring point (2,3) of each side is immovably arranged, and wherein the other one of said first and second anchoring point (2,3) of each side is movably arranged; interconnecting said first and second anchoring point (2,3) on respective side of the nacelle (1) by means of one connecting element (5) per each of the two sides; connecting each of said connecting elements (5) to a hoisting means (11); adjusting the position of each of the movable anchoring points such that each of the connecting elements (5) is vertically aligned when lifting the nacelle (1) by the hoisting means (11).
