OUTRIGGER MONITORING SYSTEM (OMS)
(OPTIONAL—STANDARD IN NORTH
AMERICA)
Description
The outrigger monitoring system (OMS) utilizes string
potentiometers to monitor the outrigger’s extension beam
positions together with the RCL. Four monitoring string
potentiometers are used on the crane, one at the end of each
outrigger extension beam to monitor if beams are at full, mid
or retracted positions. The default is to the lowest possible
load chart after sensing all outrigger positions, for example, if
three outriggers are fully extended and one is retracted, the
RCL defaults to the retracted chart.
Removal
1. Extend the outrigger beam slightly and shut down the
engine.
2. Remove the hardware that secures the outrigger cover
plate (1, Figure 7-11) and remove the cover plate.
3. Remove the OMS string potentiometer connector (2)
from the attaching point on the outrigger beam.
