OUTRIGGER MONITORING SYSTEM (OMS)
(OPTIONAL—STANDARD IN NORTH
AMERICA)
Operation
The Outrigger Monitoring System (OMS) is standard
equipment on cranes sold in North America and optional
equipment on cranes sold outside of North America. The
OMS aids the operator in ensuring that the crane is properly
setup on outriggers and jacks. The OMS utilizes one sensor
in each outrigger and one sensor in each horizontally
extending stabilizer to identify when each jack is fully
extended and an outrigger beam is positioned to one of the
two pre-defined locations, including mid-extend fully
extended position in which they provide maximum stability.
The OMS utilizes an LED indicator to communicate to the
operator the position of the outriggers. The Outrigger Status
Indicator (1, (Figure 3)) is a bi-color LED located at each
control station.
When power is on and both stabilizers beams are fully
extended and both outriggers beams are at the mid-extend
position, the Outrigger Status Indicator flashes green,
indicating a lift can be made using the capacities from the
mid-extend outrigger load chart.
When power is on and both stabilizers beams are fully
extended and one outrigger beam is at the mid-extend
position and the other is fully extended, the Outrigger Status
Indicator flashes green, indicating a lift can be made using
capacities from the mid-extend outrigger load chart.
If power is on and both stabilizers beams are fully extended
and both outriggers beams are at the fully extended position,
the Outrigger Status Indicator illuminates constant green,
indicating a lift can be made using capacities from the full-
extend outrigger load chart. If power is on and one or more
stabilizer beams are not fully extended, or one or more
outriggers are at a position other than the mid-extend or fully
extended positions, the Outrigger Status Indicator flashes
red, indicating a lift should not be made. If the Outrigger
Status Indicator illuminates constant red, there is a fault in
the OMS.
