Method for erecting a wind turbine tower

A method comprising:

• erecting a wind turbine tower having a plurality of tower segments tensioned by a plurality of tensioning members, the method comprising:
• fixing a fixing unit at first ends of the plurality of tensioning members, wherein fixing the fixing unit includes:
• placing a multi-part wedge unit at the first ends of the plurality of tensioning members, wherein the tensioning members comprise a plurality of tensioning wires;
• fitting a sleeve over the multi-part wedge unit;
• fixing a pulling tab on or at the sleeve, wherein the pulling tab has an opening;
• fixing a cable at the opening in the pulling tab;
• pulling the cable with the fixing unit and the plurality of tensioning members upwardly;
• fixing the fixing unit to a segment of the wind turbine tower for tensioning the plurality of tensioning members;
• and
• removing the sleeve over the multi-part wedge unit,
• wherein the sleeve is removed before the plurality of tensioning members are placed in tension.
