11.2 Operation of the rated capacity limiter
If the truck crane's current rigging mode is registered properly, the RCL will
prevent the permissible lifting capacity from being exceeded and the truck
crane from being overloaded.
The current rigging mode is based on measured values and manually
entered values.
During the operation of the crane, a visual and acoustic early warning is
issued before the load limit is reached and then the functions are shut down
that would lead into the overload range.
G
Risk of accident due to incorrectly set RCL
Before operating the crane, ensure that the current rigging mode is cor-
rectly entered. An incorrect entry will give you a false sense of security. This
may result in the truck crane overloading and causing an accident.

G
Risk of accident due to overridden or faulty RCL
The RCL must never be overridden.
It is prohibited to work if the RCL is switched off, overridden, out of service
or faulty.
G
Danger of overturning in two-hook operation
The rated capacity limiter only ensures safety for single hook operation.
Two-hook operation is not permitted.
