DANGER!
Danger of being injured by falling objects! Danger of
crushing and cutting!
If the independent secondary brake fails to activate and the
falling path is not cordoned off by on-site equipment then the
independent secondary brake can fall unchecked and endan-
ger other people!
– Use suitable measures to cordon off the falling path!
ATTENTION!
Danger of damage to the independent secondary brake
or other components!
When performing the following test the independent secon-
dary brake can collide with other on-site equipment and be
damaged.
– Ensure that the independent secondary brake cannot
collide with on-site equipment.
– If a collision cannot be avoided than use the other
testing method.
– Remove the independent secondary brake anchoring (e.g.
via the bolts (3) in the installation example shown).
– Raise the independent secondary brake approx. 30 cm up
the rope.
– Let the independent secondary brake fall:
The independent secondary brake must close and clamp
onto the rope after a maximum of 8 cm.
– Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
– Lower the independent secondary brake down the rope.
– Mount the independent secondary brake:
Secure the bolts with a new cotter pin.
Secure the screws with a new self-locking nut.
Method 2 (Checking the speed limitation):
See Fig. 12.
– Remove the tensioning weight from the safety rope or cre-
ate a rope loop at the rope outlet (the unloaded side of the
independent secondary brake).
– Abruptly jerk the rope in the direction 'A':
The independent secondary brake must close and hold 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.
– Re-attach the tensioning weight to the safety rope, if neces-
sary.

Operating / Operation

Personnel must have been trained by the operator in operating
the unit and be authorised to use it.
11.1 Checks to be carried out before
starting work
– Check the rope for clinging dirt and clean if necessary.
– Check that everything is ready for working, see
'10.4 Commissioning, Determine operational readiness' on
Page 10.
– Run the function test, see '10.4 Commissioning, Functional
test' on page 10.
– Record the inspection results in the logbook.
11.2 Operation with personnel lifting
equipment
DANGER!
Danger of being injured by an emergency-stop due to
the drop being too long!
The safety rope will be pushed upwards when moving
upwards with the independent secondary brake shut and it
will no longer be tensioned between the suspension point
and the independent secondary brake!
– You must always ensure that the manual lever is set to
OPEN and latched in place before moving.
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.
Note:
Where possible perform this check when beginning to move and
before the load lifting equipment has reached a great height.
If the centrifugal force weight does not turn:
– Immediately stop the load lifting equipment.
– Observe the operator's emergency plan.
– 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:
