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.
Requirement
– The engine for crane operation is running.
Overriding the lifting limit switch
• Turn the key-operated switch (1) once anti-
clockwise.
Once the lifting limit switch has been acti-
vated, the crane movement will only be
stopped once and will then no longer be mon-
itored.
Overriding the RCL
• Turn the key-operated switch (1) once clock-
wise.
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 - 48.
If you do not trigger a control lever movement within 10 seconds, you must
press the key-operated switch again.
