G. INSTALLATION OF TB-8 TELESCOPING TOP BRACKET:
See Figure 15 for a typical installation of the TB-8 top bracket onto
a round rung ladder. The top bracket should be positioned to allow
users safe access when connecting or disconnecting from the system.
The top bracket is typically mounted in the center of the climbing
surface for ease of climbing, but may be located towards the side of
the ladder if required. The TB-8 top bracket is designed to mount at
or near the top of the ladder and telescope up when in use. Typical
installations include access ladders into manholes and under trap
doors.
Installations that use the TB-8 top bracket are limited to one user on
the system at a time.
Install rung clamps using the hardware provided. Do not substitute
other fasteners. Torque fasteners to 20-25 ft-lbs (27.1-33.9 N-m).
TO OPERATE: Pull up on the bracket handle and rotate it clockwise
to lock it in place. Secure the front attachment point on a full body
harness to the carrier cable with a Lad-Saf
®
detachable cable sleeve
and climb up and down the ladder. (See the Lad-Saf
®
Detachable
Cable Sleeve User Instruction Manual for details). When you are done
rotate the bracket handle counterclockwise and allow the bracket to
slide back down into the stationary bracket.
H. INSTALLATION OF D-RING ANCHORAGE: The D-ring Anchorage
is designed for used with the DBI-SALA Force2
™
energy absorbing
lanyard and full body harness. The D-ring Anchorage must be
attached to a Lad-Saf
®
top bracket that is attached to a structure
that meets the top bracket load requirements. See Figure 16.
APPLICATION: The D-ring anchorage
must be used in accordance with local
requirements for fall arrest or rescue
systems.
INSTALLATION:
See Figure 16. Install the
D-ring anchorage assembly no more than 6
in. (15.2 cm) above the ladder rung where
the top clamp plate of the Lad-Saf
®
top
bracket is attached. The D-ring must be on
the climbing (cable) side of the top bracket.
Clamp the D-ring anchorage assembly to
the top bracket with the fasteners provided
with the assembly. Torque fasteners to
20-25 ft.-lbs (27.1-33.9 N-m).
USE:
Connect the lanyard end of the
energy absorbing lanyard to the D-ring
anchorage. Connect the energy absorber
end to the back D-ring on your full body
harness. Do not disconnect from the
Lad-Saf system before connecting to the
D-ring anchorage.
4. SWING FALLS: Swing falls occur when
the anchorage point is not directly above
the point where a fall occurs. The force
of striking an object in a swing fall may
cause serious injury. See the instructions
provided with the energy absorbing
lanyard for more information.
