TOWER SECTION AND A METHOD FOR A TOWER SECTION
Indicator device (90), for indicating proper alignment of bolt-and-nut holes of two abutting flanges (72,72′) of two tower sections (2,5) of a wind turbine tower structure (1), the indicator device (90) comprising a connector (122) for connecting the indicator device (90) to an inner face (71) of one of the flanges, and a body (100) having a first body end (101) and an opposite second body end (112) closer to the connector (122), the indicator device (90) including a resiliently deformable part (150), a pneumatic system or a hydraulic system allowing for the indicator device (90) to assume a normal configuration wherein the first body end (101) is distant from the connector (122), and a second configuration wherein the first body end (101) is located closer to the connector (122), the resiliently deformable part or pneumatic system or hydraulic system urging the first body end (101) from the second configuration towards the first configuration.
