Sectional Monopole Tower Foundation & Installation Manual, Revision A
17
TIP:
The tower is now set to be raised. Southwest Windpower recommends raising the
tower once without the wind turbine installed. This permits checking the proper opera-
tion and installation of the hinge and gin pole and also allows inexperienced installers an
opportunity to practice raising the tower without risking damage to the wind turbine.
Raising the Tower
Refer to the Skystream Owners Manual for instructions on completing the electrical connections and mounting Skystream on the tower. If you have not
raised a tower before Southwest Windpower recommends first raising the tower without the windturbine installed. This provides the opportunity to practice
the procedure without risking damage to the windturbine.
Follow these steps to raise the tower:
• Tilt the gin pole to the vertical position and using the wire rope cable (with the adjustable end) connect the end of the gin pole to the lifting tab located
at the tower mid section.
• Note that it may be necessary to adjust the length of this cable when switching between the 33.5 ft (10.2 m) and 45 ft (13.7 m) towers or because of
variations in the location of the lifting tab. Refer to the accompanying Adjusting Cable Length section for instructions.
Adjusting Cable Length
READ ALL INSTRUCTIONS bEFORE bEGINNING
• Determine the required cable length taking into account the two shackles needed to connect the cable to the gin pole and the tower.
• Turn back the cable over the thimble and install the first U-Bolt clip such that the “U” section of the bolt is in contact with the “dead” end of the cable and
is approximately 6 in (15 cm) from the base of the thimble. Refer to the accompanying figure.
• Tighten the nuts evenly, alternating from one nut to the other until reaching 30 lb-ft (41 N-m) of torque.
WARNING:
When using U-Bolt clips, extreme care must be exer-
cised to make certain they are installed correctly. The U-Bolt clip
must be installed so that the “U” section is in contact with the
“dead” end of the cable. Refer to the accompanying figure.
WARNING:
The TIGHTENING and RETIGHTENING of the U-Bolt
clip nuts must be accomplished as described in the instructions.
Only use forged U-Bolt clips – never use malleable clips in criti-
cal heavy duty applications such as raising the tower.
