2.3
System Capacity:
The FallTech SteelGrip® Temporary Cable HLL maximum capacity is two workers simultaneously, with each worker
weighing no more than 310 Lbs. inclusive of clothing, tools, etc. For multiple span systems, maximum capacity is two workers per span
with a maximum of six total workers per system, see Figures 3 and 4.
2.4
Anchorage
Requirements:
End anchors selected for use with this system must be a minimum of 5,000 lbs. (22.2 kN).
2.5
Total Allowable Free Fall
:
OSHA limits free fall to 6’ or less. The HLL system described in this manual is designed to be used overhead and
free fall should be limited to 6’ unless otherwise specified by a specific anchorage solution.
2.6
PFAS
Selection:
Only FallTech PFASs may be used in conjunction with this HLL system. The HLL may be used with FallTech shock
absorbing lanyards, FallTech self-retracting devices and FallTech fall arrestor connecting subsystems.
2.7
Clearance
Requirements:
The FallTech SteelGrip® Temporary Cable HLL is designed to react to a fall event by elongating and
deflecting to absorb energy. PFAS attached to the HLL will also elongate during a fall event. It is important to understand
clearance requirements prior to installation and use of the system. See tables and charts below for calculating minimum required fall
clearance.
* 7’ Freefall Distance scenario is only allowed when the SteelGrip® Temporary Cable HLL attached to the FallTech SteelGrip® Stanchion.
Freefall should be limited to 6’ or less when used with any other anchorage connector.
