D. INSTALLATION OF BB-8 WOOD POLE
BOTTOM BRACKET:
Bottom Bracket Installation:
See Figure 28 for a typical installation of the
BB-8 bottom bracket. 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. Use 1/2-inch
fasteners (not provided) to attach the bottom
bracket to the pole. DBI-SALA recommends using
lock washers, double nuts, or other methods to
ensure fasteners will not loosen.
Carrier Cable Tension Adjustment:
Figure 28 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 slack in the carrier cable by pulling the 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. When the correct carrier cable tension is reached, tighten the jam nut against the tensioning
nut. Cut off excess cable just below the lower saddle clip.
E. 5900172
COUNTERWEIGHT:
To install the 5900172 counterweight onto the carrier cable, loosen the saddle clips and pass the carrier
cable through the counterweight. Position the counterweight to allow users safe access when connecting
or disconnecting from the system. Tighten the saddle clips against the carrier cable.
3.7 FINAL INSPECTION AFTER INITIAL INSTALLATION AND SYSTEM IDENTIFICATION:
A.
Install the installation and service label onto the ladder or structure in a prominent location. Use the
steel wire provided with the label to attach it to the ladder or structure. Before installing the label, mark
the installation date and number of users allowed in the appropriate locations on the label. Use a metal
letter stamp to mark the label. Record the system identifi cation information in the Installation Check
Lists at the end of this manual.
B. After installation conduct a fi nal inspection of the system as follows:
• Ensure all fasteners are in place and properly tightened.
• Ensure the carrier cable is properly tensioned. Do not use the Lad-Saf
®
system if the bottom of the
cable is not secured/tensioned with the bottom bracket assembly.
• For cables terminated with a carrier clamp, the cable should extend above the carrier clamp 1.0 in. -
2.0 in. (2.5 cm - 5.0 cm).
• Ensure the carrier cable does not abrade against the structure at any point.
• Ensure the system information is recorded on the label and inspection log.
4.0 LAD-SAF
®
SYSTEM USE
4.1 BEFORE EACH USE inspect the system according to section 5.0. Do not climb a structure that is
not in good condition. Verify from the label markings that the system has been formally inspected
within the last year. Do not use a defective or improperly maintained LAD-SAF
®
system. Inspect
the detachable cable sleeve according to manufacturer’s instructions. Inspect the full body
harness according to manufacturer’s instructions.
