11.4 Operation of the rated capacity limiter
The rated capacity limiter is abbreviated to RCL (Rated-Capacity-Limiter) in
these operating instructions.
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 registered via
– Measurements,
– Acquired via manual entry.
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 accidents due to an incorrectly set RCL!
Ensure that the current rigging mode is correctly entered Before starting crane
operation. An incorrect entry will give you a false sense of security. This will
overload the truck crane and cause an accident!

G
Risk of accidents 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.
