Step 2.
Install the
anchorage
connectors.
Some
Sayfline
horizontal
lifeline
systems
include
two tie-off
adaptor
anchorage
connectors.
To ensure
the tie-off adaptor does not slide down a vertical or
sloped anchorage, the tie-off adaptor must be wrapped
twice around the structure as shown in Figure 7.
Refer to the tie-off adaptor instructions for complete
installation information. The horizontal lifeline may be
secured directly to the anchorage when the anchorage
incorporates a compatible attachment element that
meets the requirements specified in section 2.3.
WARNING:
For applications where the HLL cannot be located
overhead, contact 3M Fall Protection for application-specific clearance.
For use in accordance with CSA Z259 technical standards, the HLL may
not be installed at a height lower than 1 ft. below the user’s D-ring.
Step 3.
Secure each end of the horizontal lifeline to the
anchorage connectors with the snap hook or carabiner.
Loosen and reposition the rope tensioner as required.
Step 4.
Remove the slack from the horizontal lifeline by pulling
the rope through the tensioner by hand. To tension the
horizontal lifeline, use a pointed bar or a 1 1/4 in (32
mm) wrench and turn the tensioning nut clockwise until
the tensioner slips. Do not modify the rope tensioner to
achieve greater lifeline tension. See Figure 8. The final
tension will be 300 to 450 lbs. (1.3 to 2.0 kN).
