Retrieval Operation
―FOR EMERGENCY USE ONLY―
The MightEvac retrieval mechanism is to be used only in the event of an
emergency. Do not use for routine hoisting of personnel or materials.
NOTE: It is recommended to pull out
several feet of lifeline and hold in position
before engaging retrieval mechanism.
Always maintain tension on the lifeline
while in retrieval mode.
Pull out on the plunger pin until the ratchet
handle pops outward. It may be necessary to
rotate the handle slightly to fully engage the in-
ternal gears. The plunger pin should snap back
into its original position when the gears are fully
engaged. The unit is now in retrieval mode.
NOTE: A rescue may be executed either
by raising or lowering a person to safety.
TO RAISE: While maintaining light tension on
the lifeline, rotate the ratchet handle counter-
clockwise (CCW) to crank the lifeline into the
housing.
TO LOWER: To extend lifeline from the housing
(to lower), rotate ratchet handle in clockwise
(CW) direction. [NOTE: If the internal brak-
ing mechanism has been activated, such as
with a fall arrest, it is necessary to first crank
in the upward direction (CCW) for one-half to
one rotation, then reverse the direction (CW) to
begin lowering. A minimum of 75 lbs. (34kg) is
required for lowering.]
WARNING: Always ensure that the
plunger pin has returned completely into
the locked position when changing the
unit from retractable to retrieval mode.
Do not use the unit if it will not hold the
load while in retrieval mode.
Self-Retracting Lifeline Operation
To return the unit to the retractable mode, remove the weight from the lifeline and secure the end of
the lifeline as it will begin to retract once the internal gears are disengaged. Pull out on the plunger
pin and hold. Push inward on the ratchet handle, where it connects to the gear shaft, to disengage
the gears and let pin drop into the locked position.
