Bergey Tilt Tower Installation Manual page 15

Note: The guy wires with the lifting eyes must be on the upper side of the hori-
zontal tower sections. This eye is clipped to the top of the gin pole. These
guy wires will serve as the lifting wires until the tower is fully erected.
Note: Guy wires must be rolled out to the anchors, not let out from a coil held in
the hand or from the side of the spool. These latter two methods will allow
the wire to become severely twisted and stressed, making it very difficult
to handle.
Step 6:
When the guy wires are rolled out to all the anchors, check to ensure that the tower is at
a 90 degree angle to the line joining the side anchors and the base plate. If the anchors
were accurately placed the tower should lay close to the "uphill" anchor point (see Fig-
ure 2). If not, use a tape measure or a rope to check that the diagonal distances from
the tower top to each side anchor are approximately the same. Check also that the front
and rear anchors and the lifting anchor are in line with the tower.
WARNING: Extra care must be taken while raising the tower if the anchor place-
ment is not perpendicular (90 degrees) to the tower, or if the side an-
chors are not at the same elevation, or if the side anchors and base
plate are not in a straight line. Any of these conditions will affect the
guy wire tension as the tower is raised. Tension must be adjusted pe-
riodically as the tower is raised.
Step 7:
Assemble the 3/16" HD thimbles on the anchor rod eyes by twisting them open, press-
ing them on, and twisting them closed. Two crescent wrenches work well for this task.
There will be 3 thimbles per anchor on the 60' tower, 4 thimbles per anchor on the 80'
tower, and 5 thimbles per anchor on the 100' tower.
Slide three wire rope malleable clips (supplied in the guy set box) onto each guy wire
end. Place the wire rope clips on the wire so that the forged, grooved part cradles the
wire coming from the tower (the "tension side") and the "U-bolt" part clamps down on
the end-most section of the wire. Thread the guy wire end through the anchor rod eye
and around a thimble, double back and slide through the first wire rope malleable clip.
The guy wires are wrapped around the anchor eye thimbles as shown on the anchor
detail in Figure 5. Leave a little slack in the guy wire. Snug up the wire rope malleable
clips using a 7/16" nut driver. Tighten two of the clips. Let the other clip remain loose
until the tower has been erected and leveled.
