In some areas there are subsidies and grants available for installing renewable energy systems.
If you live in one of these areas and need an engineering analysis for this tower assembly to satisfy
your local authorities please contact us. We have an engineering analysis available for this tower
kit.
Step 3:
Tower, Base and Anchor Layout
This tower kit should only be assembled on a calm a day (no wind). The tower base and anchors
should be laid out as described in the drawing below.
The tower will be assembled laying on the ground and then tilted up into position.
If the tower is being erected on a slope it will be much easier to raise the tower if it is assembled to
the uphill side of the base as it will already be part way up as it is erected. In this case the two
“side” anchors should be at the same height or elevation on the hill as the tower base. The two
remaining anchors should be directly uphill and downhill from the tower base.
Be sure that the anchor points and base position are in a line when sighted from anchor to anchor.
This will insure that the forces on the guy wires are balanced properly, make final guy wire
adjustments simpler and will help a great deal during the actual raising of the tower. The side
anchors and tower base should also be at the same elevation. If either of these requirements are not
met, the guy wires will either tighten excessively or go slack as the tower is raised.
If the guy
wires tighten excessively the tower may buckle and collapse, causing possible injury or even
death and at the very least, damage to both the tower and the turbine. Carefully read the section
on raising the tower for further instructions on making the proper adjustments in these
situations.
