Emergency Descent; Switching Off When Overloaded - Tractel tirak T 1000 Manuel D'installation Et De Manutention Original

Installation and operating manual
ATTENTION!
Incorrect rope lengths!
Can result in damage to the device!
The rope end connection, the load bearing point or the rope
end itself must never be pulled up to or into the product or the
accessory parts!
– Use a rope with adequate length.
– Whenever necessary: Monitor the rope during operation.
Loading
DANGER!
Risk of being injured by falling objects!
– Secure loads against falling.
– Secure loads against twisting.
– Switch on the on-site main switch or insert the CEE plug into
the connector.
– Turn the EMERGENCY-STOP button to the right until it
releases:
The control unit is switched on.
– Always abide by the maximum permitted load when loading
the load lifting equipment.
Note:
Moving / rocking whilst stopped can result in the "overload"
buzzer being activated or the warning light coming on. No over-
load is present if the buzzer or the warning light switches off as
soon as the personnel lifting equipment stops moving.
Operating the hoist
– Run the hoist in the pulling direction until the rope is ten-
sioned (run hoists with two speeds at the lower speed).
– Run the hoist in the pulling direction until the load lifting
equipment is raised or pulled.
– Let down or release load.
– Observe the end of the rope when lowering or slackening.
– Stop immediately when damage, loops or knots are detect-
ed.
– Stop: Release the operating control.
If the rope / hoist does not stop when letting go of the operating
control:
– Press the EMERGENCY-STOP button.
– If the EMERGENCY-STOP button fails, disconnect the hoist
power supply (e.g. by pulling out the plug).
– Have the hoist inspected and serviced by an electrician or
authorized service personnel (see ' 15.1 Authorized mainte-
nance personnel' on page 18).

10.3 Emergency descent

The load lifting equipment can be lowered manually in the event
of a power failure.
DANGER!
Risk of being injured by falling objects!
You are only allowed to lower the load in manual mode in an
emergency.
– The hoist must always be tested by TRACTEL Greifzug
GmbH or a hoisting gear workshop that has been author-
ized by TRACTEL Greifzug GmbH after an emergency
descent.
– Any damaged or worn part found must always be re-
placed.
Risk of being injured by falling objects!
The centrifugal brake might not brake the load in case of
overloading!
– In the event of overloading, never open the service brake
(spring-applied brake) manually.
The centrifugal brake prevents rope speeds that are too high
when lowering manually.
See Fig. 16.
– Remove the lever (1) from the anchoring.
– Insert the lever (1) into the brake bracket through the slot in
the hood of the motor (2).
– Lift and hold the lever.
The load is lowered.
– Let go of the lever to brake.
– Anchor the lever again after use.
– Send the hoist to the manufacturer for testing or repair or
send it to a specialist hoisting gear workshop.

10.4 Switching off when overloaded

Hoists with a mechanical or electrical load limiting device:
The hoist's load limiting device has been set up in the factory to
activate with a maximum permitted overload of 125% of the
maximum working load. A warning signal will be sounded or a
warning light will come on when it is switched off.
Jamming of the load lifting equipment may also lead to deactiva-
tion.
When overloaded:
– 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.
