(6) Confirming that the key is removed from the ACS emergency switch
Confirm that the key is not in the ACS emergency switch on the front panel. This switch is provided to avert
possible danger in an emergency of the ACS system. Therefore, give the key to the safety supervisor when on the
work site.
The ACS emergency switch is only used to take emergency action to avoid a serious accident.
Before crane operation, take the key off the switch and it must be kept by the safety supervisor.
If the ACS emergency switch is set to the"release" position intentionally when operating the
crane, the crane tipping over or other serious accident can be caused.
