Application

2.1
Purpose: The purpose of the FallTech SteelGrip® Temporary Cable HLL is to provide horizontal mobility for workers exposed to fall hazards
and is designed as an anchorage subsystem for the attachment of up to two PFASs. The HLL is adjustable up to 100' in length for
a single span system and up to 330' in length for a multi-span system. The system is designed to be used as part of a complete PFAS. See
Figure 1.

When properly tensioned, the lifeline will react to a fall event of up to two workers by combining the energy absorbing properties of the
lifeline cable, the SteelGrip® Coil Energy Absorber, and the worker's personal energy absorber. During a fall event, the SteelGrip® Coil
Energy Absorber will deploy and elongate to safely and predictably absorb the energy of the fall event. The elongation of the
SteelGrip® Coil Energy Absorber along with the stretch of the lifeline and the expansion of the user's PFAS will result in reduced
forces to the anchor and to the user's body.
2.2
Application Limits: The FallTech SteelGrip® Temporary Cable HLL is a dynamic anchorage subsystem that will vary in its performance
depending upon the length of the system, the number of workers attached and the type of PFAS being used. Care should be taken to
understand the capacity of the system, minimum required fall clearance, anchorage strength requirements, total allowable free fall, total
allowable fall clearance, and how the user's PFAS will deploy during a fall event. Longer HLL spans will generate more lifeline deflection
and sag during a fall event and will result in greater clearance requirements. See Figure 2.
