G
Risk of accidents due to overridden or faulty RCL
It is not permitted to work with an overridden or faulty RCL.
Set down the load immediately and stop operating the crane if the RCL is
faulty.
You may only override the RCL if it becomes absolutely necessary in the
event of an emergency. This is to put the truck crane into a safe state in the
event of a malfunction. In this case, do not perform any movements that
would increase the load moment.
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 being overridden unintentionally.
