If the lead climber releases the tension on the rope,
all that is necessary to unlock the device and let out
the rope is to apply slight pressure to the braking
cam to continue letting out the rope.
Releasing and lowering (fig. 16)
The rope which is fed in should be held with the
braking hand to provide extra security.
The control lever must now be pulled gently in order
to release the tensioned rope and to lower the
person hanging on the rope.
In the process, let the rope which is fed in run
through the braking hand to provide extra security.
Only lower the person to the ground at a controlled
speed. The abseiling speed increases as the degree
of unlocking increases by means of the control
lever.
In the case of small rope diameters and heavily
used ropes with an increased diameter in particular,
the brake lever must be operated with increased
sensitivity when lowering a person.
Double-stop safety function in the event of
overload (fig. 17)
In the event of overload (braking lever pulled too far),
the braking cam auto matically springs back to the
locking position and arrests the rope. = Double-stop
safety function.
The braking lever remains in the pulled-back
position.
The braking cam can be unlocked again by gently
pushing the lever forwards, so that the person can
continue to be lowered.
ATTENTION – in the case of heavily used ropes with
an increased diameter, the lever mechanism reacts
with reduced sensitivity, which means that for safety
the rope running in must always remain clasped.
The double-stop safety function is an additional
safety function for avoiding overload with undesired
acceleration.
Active abseiling
Active abseiling occurs in a similar way to lowering,
with additional guidance of the rope running in by
the brake hand and measured unlocking by means
of the control lever.
Securing with rope deflection – Toproping (fig. 18)
For the purpose of securing with rope deflection, the
two strands of rope can also be operated directly for
pulling in the rope.
When top roping make sure that the rope does not
become slack.
REGULAR INSPECTION, REMOVAL FROM SERVICE
AND LIFESPAN
Regular inspection
Before each instance of use, the components listed
below must be inspected to see whether they have
any damage (score marks, deformations, wear) and
whether they function perfectly.
