If the mast is to be raised by hand, ensure
that it can be safely and easily managed
manually.
It is recommended that the use of a crane
or other suitable equipment be used for
anything over 6 m (20 ft.) in height, or for
hazardous area installations such as high
elevations (towers).
To minimize the possibility of the mast
becoming bent or damaged, it is very
important to keep the mast straight during
the lift.
Ensure that:
t
There are no overhead AC
power lines.
t
There is nothing overhead that will
obstruct the lift.
t
There is enough man-power available to
safely conduct the lift.
t
There is only ONE person in control of
the lift.
Remember to always Plan the Lift
before attempting it.
When ready to raise the mast, check the
following:
t
Guys to the inline coupling, guying ring
or other mast anchor points are properly
secured.
t
Ensure the guys are not twisted, kinked
or damaged in any way.
t
Ensure that each guy can be easily
secured at the base when the mast has
been raised.
Turnbuckles or rigging screws are recom-
mended at the base anchor points of the
guys to enable easy vertical alignment of
the mast and correct tensioning of the guys.
If using turn-buckles, ensure that they are
wired securely with nichrome wire.
Using conductive guying, such as stainless
steel, is acceptable as long as it is NOT
used for guying to the top of sections of
insulated FRP mast. Guying to the top of an
aluminum section of mast is acceptable.
