Emergency-Stops For Material Lifting Equipment; Measures To Be Taken After A Problem Or An Emergency-Stop - Greifzug blocstop BSO Série Manuel D'installation

– 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.
– Move downwards.
– Press the EMERGENCY-STOP (1) button while moving
downward.
Independent secondary brakes without limit switch:
– Lower the load until the independent secondary brake sup-
ports the load using the safety rope.
Independent secondary brakes with limit switch:
– Perform an emergency descent (see the documentation for
the hoist or the personnel lifting equipment) until the inde-
pendent secondary brake holds the load using the safety
rope.
If the load is not held:
– Evacuate the team and secure the personnel lifting equip-
ment in place (see above).
If the load is held:
– 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.
– Move the load lifting equipment carefully downwards and be
ready to press the EMERGENCY-STOP button on the inde-
pendent secondary brake at any time.
After every emergency-stop:
See '12.3 Measures to be taken after a problem or an emer-
gency-stop' on page 13.
12.2 Emergency-stops for material lifting
equipment
DANGER!
Danger of being injured by falling loads!
– Never stand beneath the material lifting equipment.
– Check the cause of the problem.
– Eliminate the problem.
If this was caused by a suspension rope snapping or a hoist
malfunction:
– Implement suitable measures to secure the load lifting
equipment in place so that the suspension rope or the hoist-
ing gear can be replaced.
If this was not caused by a suspension rope snapping or a hoist
malfunction:
– Try to move upwards.
If this is not possible:
– Securing the load lifting equipment (see above).
G905.5 - 02/2011
See Fig. 10.
If it is possible to move upwards then an independent secondary
brake malfunction has probably occurred.

lever (2) clockwise until it latches into place.
– Re-tighten the safety rope by hand, if necessary.
– Move downwards.
– Press the EMERGENCY-STOP (1) button while moving

12.3 Measures to be taken after a prob-
lem or an emergency-stop
DANGER!
Danger of severe accidents!
In the event of an emergency-stop the entire construction is
subjected to sudden forces. Damage to the suspended as-
sembly, the anchoring devices, the rope and the independent
secondary brake is possible.
– The independent secondary brake must be inspected by
Greifzug Hebezeugbau GmbH or an authorised hoisting
gear workshop.
– A qualified specialist must perform an on-site inspection.
– Remove the independent secondary brake and send it to
Greifzug Hebezeugbau GmbH or an authorised hoisting
gear workshop for inspection.
On-site inspection to be carried out by a specialist:
Safety rope
Safety rope anchoring point
On-site anchoring point of the independent secondary brake
and anchoring point on the load lifting equipment
All bolts and screw connections
An inspection is not needed after an activation.
