Operation and Installation Manual
–
Manually trigger the independent secondary brake on the
personnel lifting equipment.
–
Shut off the operator-side compressed air supply.
–
Observe the operator's emergency rescue plan.
–
Remove the supply hose on the hoist.
–
Have the hoist inspected and serviced by a authorized ser-
vice personnel, see ' 15.1 Authorized maintenance person-
nel' on page 16.
10.3 Emergency descent
The load lifting equipment can be lowered manually in the event
of a compressed air failure.
Risk of falling! Danger of being injured by falling objects!
The brake cannot brake the load if overloaded!
–
In the event of overloading, never open the service brake
(spring-applied brake) manually.
See Fig. 17 on page XII.
The motor's braking effect prevents rope speeds that are too high
when lowering manually.
For an emergency descent with low loads, increase the weight
using ballast and / or carefully pulling on the rope.
–
Lift and hold the lever (1). The load is lowered.
–
Let go of the lever to brake.
10.4 Switching off when overloaded
When delivered, the load limiting device has been set in such a
way that it deactivates the hoist at the latest once the load
reaches 1.25 times the load bearing capacity.
Jamming of the load lifting equipment may also lead to deactiva-
tion.
When overloaded:
–
Lower or release the hoist until the load has reached the
ground.
–
Reduce the load until no overload is present.
When jammed:
–
Lower or release the hoist until the load hangs freely again.
–
Remove the obstacle before lifting the load again.
