4.4 RESCUING A PERSON HANGING HELP­
LESSLY ON A LANYARD
Fasten the descender and rescue device safely to
an attachment point to EN 795 using the karabiner
on the device. Latch the karabiner on the short end
of the rope to the dorsal eye on the fall arrest har-
ness of the person to be rescued and secure it. The
switch-over lever of the support pawl must point
toward the short rope end attached to the dorsal
eye on the rescue harness. Turning the hand wheel,
lift the person until he/she can be detached from
the lanyard. If the lifting ratchet is used to lift the
person, push the switch-over lever of the lifting rat-
chet toward the loose end of the rope. Using the
lifting ratchet, lift the person until he/she can be
detached from the lanyard.
To descend the person, all ratchets must be swit-
ched over. Be sure to push all switches to either
green or blue, depending on the lifting or descent
direction.
Attention: The ratchets cannot and must not be
switched when the rope is loaded.
Version 1: Lifting with the hand wheel
Switch over as follows: Lift and hold the load using
the hand wheel. The support pawl is thereby relie-
ved and can be switched over. Keep holding the
load with the hand wheel. Now feed the relieved
end of the rope through the open hook, pull it down
firmly and hold it tensioned. To start the descent,
begin to let go of the hand wheel slowly and let the
rope glide through your hand slowly.
Version 2: Lifting with the lifting ratchet
To switch over, first relieve the support pawl and
then the lifting ratchet. Proceed as follows: Lift the
load using one lifting ratchet and hold the load with
this ratchet. The support pawl is thereby relieved
and can be switched over.
Attention: Keep holding the load with the lifting
ratchet.
Now feed the relieved end of the rope through the
open hook, pull it down firmly and hold it tensioned.
Now you may slowly release the lifting ratchet hol-
ding the load, then it also may be switched over or
it may be detached from the device by pressing the
eject button. Be sure to hold the load with the rope.
That is, the load is transferred from the lifting rat-
chet to the rope held down tightly. To start the
descent, begin to let the rope glide through your
hand slowly (wear gloves), then let go of it. The
descent speed is controlled automatically by the
centrifugal brake. If a person must be rescued from
a ladder, it is often necessary to control the descent
manually. The person rescuing lets the rope end
running upward glide through his hand and thereby
precisely controls the descent speed, to ensure the
person rescued is maneuverer slowly around obsta-
cles. During the rescue action direct or indirect
visual contact should be maintained permanently; if
this is not possible, good communication with the
person rescued should be established by other
means.
