9 LOAD SENSING
Please note that the load displayed by the LMI is not a direct measurement, but a calculated value
that is based on a lot of factors. Outside of the measured values (sensors), those include:
 Operator settings such as:
o Operating mode/configuration
o Parts of Line/Reeving
 Rigging parts such as:
 Hookblock weight
 Sling weights, etc.
 Tip height (length of load line used)
 Boom weights
 Boom attachments such as
 Stowed jibs
 Auxiliary boom nose, etc.
9.1 LOAD SENSING ERROR - FLOW CHART
Correct whichever
value differs
Load Sensing Error
Verify operator’s settings are correct
Verify angle, length, and pressure readings
Press the info
button twice
Do the
displayed
values differ
from the actual
value?
NO
YES
Zero pressure transducers,
calibrate angle and length
If a problem still persists,
replace the pressure
transducer block.
