A wheel straightening apparatus including a rotatable attachment mechanism radially connected to a spindle that includes a locking cuff radially surrounding the spindle a sleeve coaxial to and rotatably connected to the locking cuff, an arm member having a first end and a second end opposed to the first end, a first face and a second face opposed to the first face, the first face of the elongated member connected to the sleeve at a location proximate to the first end and oriented parallel to the outer surface of the locking cuff, the arm member projecting perpendicularly outward from the locking cuff relative to the first edge of the locking cuff and a socket connected to the second face of the arm member at a location proximate to the second end of the arm member configured to removably receive a wheel working appliance.

The invention relates to a device (100), a system (10) and a method for modifying the cross section of a tower section (1) of a wind turbine, wherein the tower section comprises a flange (4) located at an end (3) of the tower section having a plurality of through holes (5) spaced around its circumference for securing said tower section to another wind turbine section. The method comprises securing tensioning mechanism (14) to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed; and applying a tensile force between said pair of holes in the flange of the tower section.
