The tower should have no more than a gentle bend from base to top. If the bow be-
comes more than about one foot, the side guy wires or the lifting wires should be ad-
justed before proceeding further.
This sequence of observing, communicating observations, issuing commands to guy
tenders, adjusting guys, and retightening wire rope clips must be well understood by all
members of the team before lifting or lowering starts. It is a continuing process
throughout the lifting/lowering sequences. Particular care should be taken at sites
where guy wires might catch on tree limbs, roots, rocks, or other obstructions.
A guy wire will have about 50 pounds of tension when the tower is properly erected.
This amount of tension is a comfortable but hearty pull on the wire for an average crew
member. The uppermost guy wire will have one foot to two feet of droop with 50
pounds. Letting out just six inches of the top guy wire will add approximately two feet of
droop to the wire and will cause the tower to move over a few inches at the attachment
point.
Tower Lift Crew
The following is a suggested guide to forming an efficient and safe crew to erect a BWC
EXCEL1 tower.
Four members:
1. One member to operate the winch and serve as the key person or leader.
2. Two people to attend to and adjust each side guy anchor. These individuals must be
familiar with taking in and letting out guy wires.
3. One person free to assist in holding or pulling guy wires as required. This person
should also continuously observe the guy wires and the entire lifting operation for
any unusual or dangerous situations.
WARNINGS: The following warnings should be carefully observed as part of any
tower siting and raising or lowering operation. Some of the following
warnings or cautions have been highlighted in the appropriate sec-
tion of this manual.
1. Read and follow the TOWER INSTALLATION MANUAL
2. DO NOT climb the tower.
3. DO NOT erect the tower within 1 1/2 times the tower height of electric power
lines.
4. DO NOT place guy anchors near roads, driveways, or normal paths for vehicles.
5. DO NOT permit unauthorized persons on the tower site while the tower is being
raised or lowered.
6. DO NOT use a tractor or truck to erect the tower without exercising extreme cau-
tion.
