Overriding RCL or lifting limit switch for rigging work
For rigging work, you can:
– Override the lifting limit switch
– Override the RCL and thus enable a degree of utilisation of up to 110%.
H
For both overrides the speed of the movements which increase the load
moment is reduced to 15%.
The speed of the movements which increase the load moment is not
reduced.
Overriding the lifting limit switch
• Turn the key-operated switch (1) once
anticlockwise.
Once the lifting limit switch has been
activated, the crane movement will only be
stopped once and will then no longer be
monitored.
RCL override
• Turn the key-operated switch (1) once
clockwise.
Now a degree of utilisation of up to 110% is
enabled.
After overriding
– The status indicator will light up red.
– The RCL will show an information code;
à p. 11 - 46.
If you do not trigger a control lever movement within 10 seconds, you must
press the key-operated switch again.
Cancelling the override
The override will be cancelled when you:
– press the key-operated switch again, or
– do not activate the control lever for 10 seconds, or
– switch off the ignition.
S
Risk of accidents due to unintentional override!
The key must not remain in the key-operated switch while the crane is
operating!
This prevents the RCL from overriding unintentionally.
