4011 Skyloc™ Self Retracting Lifeline: The 4011 SRL utilizes an
external energy absorber integrated into the lifeline itself. This does not
change fall clearance calculations for this unit.
4009 Skyloc™ Self Retracting Lifeline with 3014 Tieback Hook:
When tying back on to the lifeline, point of tie back must be below the
webbing impact indicator (see Figure 2).
Using the 4004, 4005, 4006, 4007, 4008, 4009, or 4011 with a Man-Lift :
1. If the unit DOES NOT employ an external shock absorber, then
the user must connect the SRL directly to the harness (see 'Instal-
lation Procedures') to provide shock absorption in the event that the
user falls over the hand rail.
2. If the unit DOES employ an external shock absorber, then the
shock absorber end must be attached to the users back to provide
shock absorption in the event that the user falls over the hand rail.
Based on testing results, if a user does not have a shock absorbing
device on their back (whether it be a unit with internal brakes or an
external shock absorber), the arrest load is isolated at the hand rail
and the user could be over loaded with no shock absorption.
3. Do not extract an amount of lifeline from the SRL and 'clip it off'
to prevent it from retracting back into the unit. Doing so will ensure
that a free-fall occurs if the user falls out of the basket and over the
handrail, and will prevent the SRL from functioning properly.
CALCULATE THE FALL CLEARANCE!
1) Determine distance beneath walking/working surface to nearest lower level
or obstruction : Minimum Required Clearance - MRC
2) Add the Activation Distance - Distance required for lifeline to activate -
Activation Distance - AD = 12" (.3m)
3) Add the Deceleration Distance - DD. No more than 30" (.76m)
4) Add the Safety Factor: Safety Factor - SF. 1.5' to 3' (.4 to .9m)

AD + DD + SF < or = MRC
