摘要： An arrangement and a method to align a part of a wind turbine to a counterpart is provided. The arrangement includes an alignment tool. The alignment tool includes a first area to be connected to a part of the wind turbine, and a second area that protrudes over the physical dimensions of the part of the wind turbine. The second area is arranged and prepared in a way that it abuts on the counterpart during the alignment of the part of the wind turbine and its counterpart. The arrangement includes a second alignment tool. The second alignment tool protrudes less far over the physical dimensions of the part of the wind turbine then the first alignment tool. Thus the first alignment tool abuts to the counterpart before the second alignment tool when the part of the wind turbine approaches the counterpart.
