4.2 Function description
4.2.1 Load moment limitation
The RCL gives the operator information needed to operate the
machine within the operating ranges specified by the manufacturer.
The operator's experience, prudence and judgment are required to
ensure safe operation of the RCL.
Using sensors, the RCL monitors machine functions and continu-
ously provides the performance data of the machine to the oper-
ator. This data changes continuously as the machine moves. When
the machine approaches the maximum load rating, the RCL warns
the operator via a warning tone and a visual signal.
If the machine reaches the inadmissible area of operation, any
machine movements which increase the machine load moment are
shut down. In order to unload the machine after the RCL is tripped,
