7 OPERATION

Upon correct inspection the LMI is operational. The operator shall be thoroughly familiar with all

controls of the LMI 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 LMI.

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

reverification of the cranes LMI calibration.

Any structural modifications or changes to the crane shall require reverification of the

cranes LMI calibration.
