Final Tower Raising; Figure 15: Guy Wire Transfer Sequence - Bergey Tilt Tower Installation Manual

7) Final Tower Raising

Tools Required:
7/16" nut driver (several)
Procedure:
Step 1:
Short-circuit the EXCEL1 alternator by twisting or bolting the output wires together. This
will keep the wind turbine from spinning during the raising of the tower. If the Power-
Center connections have already been made, this can be easily done by moving the
positive lead over to the negative terminal.
Step 2:
Follow Steps 1 through 3 of the Initial Tower Raising instructions in Section 4.
Step 3:
Transfer the lifting guy wires one at a time from the gin-pole to the forward anchor, as
shown in Figure 15. Secure each wire with wire rope clips, being sure to maintain ten-
sion on each cable as it is transferred. Start with the top level and work down.

Step 4:
Again, use a carpenter's level on the base tube to check that the tower is vertical in all
directions. Make a final adjustment of all guys to ensure that the tower is straight. On
the taller towers this may take some time due to the number of wires involved.
Step 5:
Pull all guy wires tight by hand with approximately 100 pounds of tension. Tighten the
second and third wire rope clips on each guy wire. There will be a small amount of visi-
ble slack in all guy wires. This is normal.
