5.1 Installation of Top Bracket Assembly

The top bracket assembly may be installed to
extend above the ladder to allow workers to step
safety onto the platform without disconnecting
from the lifeline. It is recommended to be
mounted at the center of the ladder for ease of
use and access, but can be installed toward the
side of the ladder if required.
For typical installation of the 5
ft. (1.5m) top bracket assembly,
refer to Figure 1a. This installation
to four (4) users simultaneously. The
7 ft. (2m) and 10 ft. (3m) top bracket
assemblies are installed as shown in
Figure 1b. [Note: All systems using
the 10 ft.
(3m) top bracket assembly are
limited to two (2) users.]
An extra rung clamp assembly may
be used in the installation of the top
bracket to lower the loads transmitted
to each ladder rung (see Fig. 1c).
For systems limited to one (1) user,
the 5 ft. (1.5m) top bracket may
be installed with two rung clamp
assemblies (see Fig. 1d). Ensure the
ladder will withstand the loads
between the two rungs.
1. Place the top bracket against the
rungs of the ladder at the desired
height (see either Fig. 1a or 1b). Install
For 5 ft. (1.5m) bracket: Place U-bolt around the
rung of the ladder and through the holes provided at
the bottom of the bracket.
For 7 ft. (2m) or 10 ft. (3m) bracket: Place bolts
through the holes provided at the bottom of the
bracket and through mounting plate on opposite side
of ladder rung as shown.
Install washers and torque fasteners to 20 plus or
minus 2 ft. lbs.
WARNING: The bottom U-clamp must be installed
correctly or the bracket may slip under load.
2. Continue to hold bracket against the rungs of the
ladder. Install rung clamp assembly by placing U-bolts
around the rung of the ladder and inserting through the
mounting plate. Install washers and torque fasteners
to 20 plus or minus 2 ft. lbs. Repeat procedure for
remaining rung clamp assemblies.
