2.3
System Capacity:
The FallTech 4-Person Temporary HLL maximum capacity is four workers simultaneously, with each worker weighing no
more than 310 lbs. inclusive of clothing, tools, etc.
2.4
Anchorage Requirements:
End anchors selected for use with this system must be a minimum of 5,000 lbs. (22.2 kN) for one and two
workers and 6,000 lbs. (26.7 kN) for three and four workers. If used in applications with leading edge hazards, anchorage locations must
be selected so that the deflected HLL shall not come in contact with a leading edge in the event of a fall.
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 energy
absorbing lanyards, FallTech self-retracting devices and FallTech fall arrestor connecting subsystems.
2.7
Clearance Requirements:
The FallTech 4-Person Temporary 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. Failure to calculate the fall clearance required when using the
system could result in contact with a lower level or obstruction during a fall event and could result in serious injury or death. See tables
and charts below for calculating minimum required fall clearance.
* 7’ Freefall Distance scenario is only allowed when the FallTech 4-Person Temporary HLL is attached to the FallTech SteelGrip
®
Stanchion.
Freefall should be limited to 6’ or less when used with any other anchorage connector.
