Rotate for overridden slewing gear shutdown
If the slewing gear is not switched off due to the load torque, turning can be
released within the permissible operating range. For example, for emer-
gency unrigging when the counterweight cannot be fully pre-stressed.
Overriding shutdown procedures
•
Press the button (
2
) in at the top.
– The lamp (
1
) lights up.
– The lifting limit switch is overridden.
– Slewing in permissible working range will be released.
– The slewing speed is limited to about 6%.
Cancelling the override
•
Release button (
2
).
– The lamp (
1
) goes out.
– The lifting limit switch override is cancelled.
– The slewing will be blocked (if the shutdown is still pending).
S
Risk of damage due to overridden slewing gear shutdown.
The slewing is not monitored if the shutdown is overridden.
Before slewing, always make sure that the superstructure and the counter-
weight (partially lowered if necessary) cannot damage any parts in the
slewing range.
