3.5 INSTALLATION OF CABLE GUIDES, ALL MODELS:
Cable guides protect the carrier cable from chafi ng against the
ladder or structure and to prevent the climber from excessively
defl ecting the cable from side to side. Cable guides should be
positioned at approximately 25 ft (7.62 m) intervals along the
carrier cable between the top and bottom brackets, and at any
point along the system where the cable may abrade against the
structure. Cable guides should be staggered along the system
to reduce harmonic effects of the wind, such as at 23 (7.01), 25
(7.61), and 27 (8.23) feet (m) intervals. For high wind areas “L”
shaped cable guides may be used. The “L” shaped cable guides
should be alternated with opening on the left, then right, etc. up
the ladder. Latching cable guides are also available.
Direct Connection to Ladder:
See Figure 19 for a typical installations of cable guides onto
a ladder. Some cable guides utilize rung spacers and clamp
plates while others do not (see Figure 3). Install the cable guide
using the hardware provided. Do not substitute other fasteners.
Torque fasteners to 20-25 ft-lbs (27.1-33.9 N-m).
SO-7 Weld-on Stand-off Support Installation:
Install the SO-7 stand-off as shown in
Figure 20. See section 3.2 for welding
recommendations. The stand-off must be
perpendicular to the pole surface and in-line
with the carrier cable.
Angle Leg and Round Leg Stand-off
Support Installation:
See Figure 21 for typical installations of angle
leg and round leg stand-off supports. Install the
stand-off support using the hardware provided.
Do not substitute other fasteners. Torque
fasteners to 20-25 ft-lbs (27.1-33.9 N-m).
Install the cable guide to the stand-off support
using the hardware provided. Do not substitute
other fasteners. Torque fasteners to 20-25 ft-lbs (27.1-33.9 N-m).
