Installation and operating manual
– Stop the hoisting gear.
– Check whether the safety rope is hanging free.
– Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
– Re-tighten the safety rope by hand, if necessary.
– Only continue with the original movement after the safety
rope has been re-tensioned.
11.3 Operation with material lifting
equipment
See Fig. 10 (example).
– Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
– Start the hoisting gear.
– Check the inspection window (4) during every run to see
whether the centrifugal force weight is turning.
If the centrifugal force weight does not turn:
– Immediately stop the load lifting equipment.
– Remove the independent secondary brake and send it to
Greifzug Hebezeugbau GmbH or an authorised hoisting
gear workshop for inspection.
Safety rope is not tensioned
If the safety rope is not under tension when the independent
secondary brake is closed:
– Stop the hoisting gear.
– Check whether the safety rope is hanging free.
– Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
– Re-tighten the safety rope by hand, if necessary.
– Only continue with the original movement after the safety
rope has been re-tensioned.

11.4 Manual EMERGENCY-STOP

Press the EMERGENCY-STOP button to manually trigger the
independent secondary brake in an emergency situation.

11.5 Securing the load

The independent secondary brake can be used to secure the
load during work breaks. This relieves the strain on the rope hoist
gearbox, for example.
Note:
– Please follow the operator's work instructions and safety
measures and the notes in the operating manuals for the
hoisting gear and load lifting equipment.
EN-12
See Fig. 10 (example).
Securing the load:
– Trigger the independent secondary brake via the EMER-
GENCY-STOP button.
Re-open the independent secondary brake:
– Move upwards slightly to reduce the strain on the rope.
– Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
– Re-tighten the safety rope by hand, if necessary.
– Only continue with the original movement after the safety
rope has been re-tensioned.
12 Immediate measures to be
taken after an emergency-stop
An emergency-stop means that the independent secondary
brake was triggered by a hoist malfunction or suspension rope
breakage, for example.
12.1 Emergency-stops for personnel lift-
ing equipment
DANGER!
Danger of severe injuries caused by incorrect proce-
dures!
– Keep calm.
– Check out the cause.
– Eliminate the problem.
If this was caused by a suspension rope snapping or a hoist
malfunction:
– Evacuate the team. See the personnel lifting equipment
documentation or, if available, the operators' emergency
rescue plan.
– Implement suitable measures to secure the personnel lifting
equipment in place so that the suspension rope or the hoist-
ing gear can be replaced.
– Tension the safety rope on the ground.
If this was not caused by a suspension rope snapping or a hoist
malfunction:
– Try to move upwards.
If this is not possible:
– Evacuate the team and secure the personnel lifting equip-
ment in place (see above).
See Fig. 10.
If it is possible to move upwards then an independent secondary
brake malfunction has probably occurred.
