WARNING
If the light and audible alarm do not function as described and the crane movements are not
stopped, the system is not working properly. The malfunction shall be corrected before op-
erating the crane.
5.
If the crane is equipped with a boom extension, repeat the test procedure for the boom extension
anti two-block switch.
6.
Check that the display of the main boom length agrees with the actual boom length.
7.
Check that the display of the main boom angle agrees with the actual boom angles.
8.
Check that the display of the operating radius of the crane agrees with the actual radius.
9.
Check the load display by lifting a load of known weight.
5.1
OPERATION
After being properly checked, the LMI is operational. The operator shall be thoroughly familiar with all
controls of the LMI and he shall properly set the Reeving Switch (external unit) before operating the
crane. The proper function of the system shall be checked by lifting a load of known weight and com-
paring 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.
WARNING
If any of the displays reflect 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 LMI calibration.
WARNING
Any structural modifications or changes to the crane shall require re-verification of the
crane's LMI calibration.
