At this point the tower should be checked for guy wires that are slightly too tight or too loose. Guy
wires that are too tight will cause the tower to bow. The proper pre-tension is essential to avoid
buckling the tower. If they are too loose the tower will usually sway back and forth a bit. A simple
test for guy wire tension involves pulling or pushing the guy wire with about 15 to 20 pounds
approximately 36.00” from the guy attachment.
The guy wire should move approximately 6.00” – 10.00” total. If the cable moves less than this, the
guy wire is probably too tight. If the guy wire moves more, the guy is probably too loose. The proper
tension is where there is no tension and no slack. This is easily achieved by hand without
turnbuckles. Correct any mis-adjusted wires by loosening their cable clamps one at a time, adjusting
the wire and re-tightening the clamps.
With the gin pole secure, the rope should be removed from the snap links, coiled and set aside.
Thread the slack end of the upper gin side wire through the two clamps, the anchor (with thimble)
and back through the clamps. Unclip the wire from the gin pole snap link, and without letting go of
it, adjust the wire and tighten the clamps at the anchor. Repeat these steps with the lower gin-pole
side wire. Once all the guy wires are attached to their anchors the gin pole can be removed from the
tower base.
