ERECTION
Erection should only be attempted in light winds.
The tower should first be erected without the wind generator fitted. Raise the tower to it’s working
position by pivoting about it’s base fixing. Ensure the rear rigging screw does not become detached
from it’s anchor point. Attach the free guy to it’s anchor point to secure the tower in it’s vertical
position.
With the aid of a spirit level, adjust the rigging screws until the tower is vertical and the guys are
suitably tensioned. Attach the 4 lower guys to their rigging screws by looping the free end through
the eye of the rigging screw and thimble and secure using 3 rope grips. Tension as for the upper
guys. Ensure the tube is straight and vertical.
The tower can now be lowered by reversing the procedure for raising. It may be necessary to slightly
slacken the side guys during this procedure.
The wind generator cable can now be installed down the centre of the tower and the wind generator
fitted to the tower top. The tower can be raised in the same previous manner; the guys tensioned
ensuring the tower is straight and vertical.
After tensioning of the guys, the rope grip nuts should be checked for tightness, this should be
repeated after 24 hours. Further periodic checking and tightening of the nuts is essential during
service, more frequently during early stages of operation to ensure long term reliability of the
structure.
