3.5 CABLE GUIDE:
Figure 4 ANSI, CSA, AS/NZS, CE
CG-3
INSTALLATION OF CABLE GUIDE:
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.
Direct Connection to Ladder:
See Figure 10 for a typical installation of a cable guide on a ladder. Install the cable guide (A) using the
hardware provided. Do not substitute other fasteners. Torque fasteners to 1.1-1.8 ft-lbs (1.5-2.5 N-m).
3.6 BOTTOM BRACKET:
Figure 11 ANSI, CSA, AS/NZS, CE
BB-1 6100298
INSTALLATION OF BOTTOM BRACKET AND CARRIER CABLE TENSION ADJUSTMENT:
Before installing the bottom bracket it is recommended that the ladder and/or climbing structure be
evaluated by a qualifi ed engineer to determine if the load requirements for the system specifi ed in section
2.3 are met.
Depending on the length of the system, and the environment in which the system is installed,
NOTE:
it may be necessary to periodically re-tension the system. Extreme temperature ranges and very
long systems will likely require periodic re-tensioning. The tension indicator can be purchased
separately. Contact DBI-SALA for details.
A. INSTALLATION OF BOTTOM BRACKET:
Direct Connection to Ladder:
See Figure 11 for a typical installation of the bottom bracket onto a ladder. Components:
A Carrier Cable
B. Saddle Clip
C. Tension Rod
D. Tension Indicator
E. Washer
F . Tensioning Nut
G. Jam Nut
The bottom bracket should be positioned to allow users safe access when connecting or disconnecting
from the system. The bottom bracket must be mounted in-line (vertically) with the top bracket.
Install the rung clamps using hardware provided. Do not substitute other fasteners. Torque fasteners to
12-13 ft-lbs (16.3-17.6 N-m).
Carrier Cable Tension Adjustment:
Figure 11 shows the assembly of the tension rod to the bottom bracket and carrier cable. Loosely clamp
the saddle clips around the carrier cable. Slide the tension rod down the carrier cable and through the
hole in the bracket until suffi cient threads are exposed to allow the installation of the tension indicator,
washers, and nuts. Remove the slack in the carrier cable by the pulling cable though the saddle clips.
Tighten saddle clips to 35 ft.-lbs (47.5 N-m). Tighten the tensioning nut until the ring on the tension
indicator is sheared off. A small amount of grease on the tension rod threads will reduce the effort
required to tension the carrier cable. If there are insuffi cient threads exposed to fully tension the carrier
cable, pull more carrier cable through the saddle clips on the tension rod and repeat the procedure.
