Ground Station Outrigger Control Panel
The following paragraphs describe the outrigger controls and
indicators (Figure 3-3) found on the ground station outrigger
control panels.
Outrigger Control Panel
There is one outrigger control panel on each side of the
machine fender decking, as shown in Figure 3-3. The follow-
ing details apply to both control panels as indicated.
• The panel on the right side operates the horizontal
outrigger beams for that side only.
• The panel on the left side operates the horizontal
outrigger beams for that side only.
• The vertical stabilizers (jacks) may be operated from the
left or right side of the unit.
• Each control panel features a control switch for raising
and lowering the single front outrigger (SFO).
• Each control panel features an emergency stop switch.
Outrigger Beam Selector Switch
The outrigger beam selector button (1, Figure 3-3) is used to
operate the front or rear outrigger beam on the same side of
the crane the ground control is located.
Extend and Retract Buttons
The extend and retract buttons (3, 4, Figure 3-3) operate
both the outrigger beams or the jacks.
After pushing the desired selector button, pushing the extend
or retract button energizes the control solenoid to allow
hydraulic fluid to flow through the control solenoid valve and
the individual solenoid valve and move the selected compo-
nent in the desired direction.
Single Front Outrigger Button
The single front outrigger (SFO) button (5, Figure 3-3) is
located in the center of the of the top row of buttons of the
ground station outrigger control panel. It must be used with
the extend/retract button to control the operation of the SFO.
The SFO retracts automatically when any of the other four
jacks are retracted; therefore, it must be reset if lifting is to be
continued.
If not equipped with an SFO, the LED indicators above the
SFO button illuminate red.
Jack Selector Button
Use the jack selector button (2, Figure 3-3) to indicate which
jack you desire to operate.
Emergency Stop Switch
There is an emergency stop switch (9, Figure 3-3) on the
outrigger controls on each side of the carrier. Pressing either
switch shuts down the engine.
NOTE: Use the emergency stop switch only in the case of
an emergency to shut down the engine; do not use
the emergency stop switch regularly as a means of
turning off the machine.
