For worst case clearance calculations the user of the FallTech SteelGrip® Cable HLL systems may opt to use the ANSI Z359.14 maximum
deceleration distances when determining clearance requirements. ANSI Z359.14 allows up to 24” of deceleration for Class A SRDs and up
to 54” of deceleration for Class B SRDs. The charts below demonstrate clearance requirements below the working surface when using
the FallTech SteelGrip® Temporary Cable HLL and attaching either Class A or Class B SRDs to the HLL. Overhead anchorage only.
2.8 Rescue:
The FallTech SteelGrip® Temporary Cable HLL is part of a complete PFAS. It is not intended as a rescue device. Users of this
system presents a wide variety of potential rescue scenarios. Users of this system should understand their work environment and
develop a rescue plan accordingly. It is recommended that a trained on-site rescue team be present during use of the system.
3.0 System Requirements
3.1
Anchorage Strength:
End anchors selected for use with this system must have a minimum rating of 5,000 lbs. (22.2 kN).
3.2
Structure:
The mounting points for the anchorage must be capable of supporting no less than 5000lbs, see Figure 6.
