When securing the fiberglass guys, use
the guying grips supplied in the guying kit,
carefully following the instructions provided.
Use of alternative wire rope
grips is acceptable but ensure that:
• Grips are made of a suitable material
to PREVENT corrosion.
• There are a minimum of
3
grips per
guy end.
• Grips are spaced at a minimum of
30
mm
(
1
¼ in.) on guys (or
6
x guy diameter).
• Grips are correctly orientated - grip base
(saddle) on the ‘live’ side of the guy and
‘U-bolt’ over the ‘dead’ side or tail of
the guy.
• No more than
60
cN-m (
5
lbf-in.) of torque
is applied to the grip.
The above recommendations should also
be used for any other guying, i.e.: stainless
steel, when used on any mast.
Important
recommendations:
• When guying any mast, it is advisable
that the guying angle be no greater than
60
° from horizontal.
• It is recommended that
8
mm (
⁵⁄₁₆
in.)
diameter stainless steel guying saddles
are used for the base guy anchor points.
If these are to be anchored to a concrete
surface, then
6
mm (¼ in.) diameter x
40
mm (
1 ⅝ in.) depth (minimum) masonry
anchors or similar should be used.
• nVent ERICO can provide wind load ratings
per mast type to the structural engineer.
• Each of the guying kits comes with six
stainless steel thimbles to relieve stress
on the guys at the anchor points. These
thimbles MUST be used when guying,
(see Figure
21
).
• When using shackles (
5
mm (
³⁄₁₆
in.)
minimum), ensure that the shackle pins
are secured with nichrome wire.
