3.8 KNEE-LEVEL TIE-OFF APPLICATIONS: If the HLL System is installed at a height of less than 3.0 ft. (0.9 m) above the
working platform, then it is considered a knee-level tie-off application. The following criteria should be observed with
knee-level tie-off applications:
• Connecting subsystems used with the HLL System must be rated for tie-off at knee-level or below, in addition to
meeting the requirements specified in Table 1.
• Reduce the system capacity to one user per span.
;
This section does not apply to HLL Systems meeting "Large System Setback" application requirements for use with
SRDs. For installation requirements for these systems, see Section 3.7.C.
3.9 USER CAPACITY ABOVE LIMITS: If the user's total capacity (including clothing, tools, etc.) exceeds 310 lb. (140 kg),
adaptations can be made to accommodate a single user of up to 420 lb. (190 kg) total capacity.
For users with a total capacity between 310 lb. - 420 lb. (140 kg - 190 kg), the following guidelines must be observed:
• Reduce capacity to one user per span.
• Use a connecting subsystem with a maximum capacity of 420 lb. (190 kg) or greater.
• Use the two-user Required Fall Clearance values from the 310 lb. (140 kg) Fall Clearance charts, but apply instead to
a single user of up to 420 lb. (190 kg) total capacity.
3.10 BEFORE INSTALLATION: Determine the location of your anchorage points and evaluate the strength of the anchorage
structure in accordance with the anchorage requirements listed in Table 1. Determine the span length between your
anchorage points and evaluate the fall clearance requirements per your connecting subsystem type. See Section 3.2 for
more information. Do not install the system if there is insufficient fall clearance. Shorten span length if necessary to stay
within the available fall clearance.
3.11 INSTALLING THE EZ-LINE HLL: Figure 12 illustrates installation of the EZ-Line HLL. Whenever possible, locate the
horizontal lifeline such that the user is restrained from reaching the fall hazard. If rigging as a Restraint system is not
possible, rig the system such that the potential free fall is minimized. To install the EZ-Line HLL:
1. Verify that the Anchorages (A) have been installed per the requirements of Section 3.2. Any anchorage connectors
that are used should be installed per the manufacturer instructions.
2. Secure the HLL System between the anchorage connectors. First, secure the Connector (A) at the top of the HLL to
one of the Anchorage Connectors (B). Then, press and hold down the Unlock Button (C) located atop the housing to
begin extending the lifeline.
;
If used, Rolled Metal Energy Absorbers should be installed so that they are able to pivot freely with adjustment
of the system.
3. With the Unlock Button still held down, extend the lifeline of HLL System until the Connector (A) at the end of the
lifeline can be secured to the second Anchorage Connector (B). When the Connector is secure, release the Unlock
Button. This should cause the Button to spring back up and the lifeline to lock into place.
;
If the lifeline does not lock into place, remove the system from service immediately.
4. Connect the Crank Handle (A) to the Top Output (B). Remove any excess slack in the lifeline by rotating the Crank
Handle clockwise. The lifeline should be tensioned until a "click" is heard and there is a slight rotation of the Crank
Handle. When the Crank Handle is released, it should return to its original position in line with the crank body.
;
For 3M Rooftop Anchor installations, the wire rope should be tensioned only enough to raise it slightly above
the working surface.
5. If slack is needed to make an adjustment to the system, connect the Crank Handle (A) to the Top Output (B) and
rotate clockwise about 20 degrees (20°) while holding down the Unlock Button (C). Then, with the Button still held
down, rotate the Crank Handle counterclockwise until there is enough slack for an adjustment.
3.12 REMOVING THE HLL SYSTEM: Figure 13 illustrates removal of the EZ-Line HLL. To remove an installed system:
1. Connect the Crank Handle (A) to the Top Output (B) and rotate clockwise about 20 degrees (20°) while holding down
the Unlock Button (C). Then, with the Button still held down, extend the lifeline slightly past its end anchor. After this
is done, disconnect the HLL System from the anchorage connection points.
2. Retract the lifeline back into the housing by connecting the Crank Handle (A) to the Bottom Output (B). Rotate
counterclockwise until the lifeline is fully retracted.
