Operation
Upon correct inspection the RCL is operational. The operator shall be thoroughly familiar with all controls
of the RCL before operating the crane. The proper function of the system shall be checked by lifting a load
of known weight and comparing the load to the information displayed on the RCL.
Rated loads include the weight of the hook block, slings, and auxiliary load handling devices. Their
combined weights shall be subtracted from the listed load capacities as stated on the load capacity chart
to obtain the net load to be lifted.
If any of the displays reflects a deviation between displayed and actual values, an authorized PAT
service representative shall be called for repair of the system or re-verification of the crane’s RCL
calibration.
Any structural modifications or changes to the crane shall require re-verification of the crane’s RCL
calibration.
