Extending/Retracting the Outriggers Beams
To extend or retract the O/R beams, perform the following
procedure:
1. Using the Jog Dial, or the Arrow Buttons at the
Navigation Control Pad, select the O/R Beam icon
(6, Figure 4-96) (icon will turn orange when selected).
2. Press the Jog Dial, or the OK Button at the ODM, to
make the O/R Beam icon active (icon will turn green
when active).
3. To extend the O/R beams, position the Outrigger
Extend/Retract Switch (17, Figure 3-9) on the left
armrest to the extend position, then push and hold one
or more of the four buttons at the Jog Dial or the
Navigation Control Pad (Figure 4-95).
To retract the O/R beams, position the Outrigger
Extend/Retract Switch to the retract position, then push
and hold one or more of the four buttons at the Jog Dial
or the Navigation Control Pad.
NOTE: The O/R beam positions correspond to the four
buttons at the Jog Dial and the ODM Navigation
Control Pad (Figure 4-95 and Figure 4-96).
When a button at the Jog Dial or Navigation Control Pad is
pushed and held, the corresponding O/R beam image turns
orange to indicate that it is actively moving. An arrow will
appear to indicate whether the beam is extending or
retracting. In the following example (Figure 4-96), the top
image shows the Left-Front O/R beam is extending and the
bottom image shows the Left-Front O/R beam is retracting.
If operating the crane with the outrigger beams in the
mid-extended position (50%), use the Percentage Outrigger
is Extended field (7, Figure 4-96) to achieve the desired
position. When programming the RCL, if the outrigger beam
position does not match the RCL rigging code the outrigger
beam over-ride warning screen (Figure 4-185) will show on
the RDM. Operator must visually inspect to confirm outrigger
beam position using the markings on each outrigger beam.
