Outrigger Extend/Retract Switch
NOTE:
The park brake in the carrier cab must be set
before the outrigger controls will operate.
Be sure the outriggers plus the center front
stabilizer are properly extended and set, and the
crane is level for operation on outriggers. The
center front stabilizer outrigger is a vital factor in the
stability of the crane.
All four outrigger beams must be equally extended
to the mid position vertical stripe or fully extended
position before beginning operation.
While in craning mode (operating from the
superstructure), carrier outrigger controls are
ignored while superstructure cab outrigger controls
are being activated and superstructure cab
outrigger controls will be ignored while carrier
outrigger controls are being activated. All outrigger
functions are disabled while performing a craning
function such as swing, lift, tele or hoisting. Crane
functions such as swing, lift, tele or hoist are
disabled while outrigger controls are being
activated.
The center front stabilizer will retract automatically
when the extend/retract switch is activated in the
retract position for any stabilizer; therefore the
center front stabilizer MUST be reset if any craning
functions are to be continued.
The outrigger extend/retract momentary switch (1)
(Figure 3-17) is located on the side of the controller. It must
be used in conjunction with the outrigger selector switches to
control the operation of the stabilizer and extension
cylinders.
Push the top of the switch to select the extend function or
push the bottom of the switch to select the retract function. In
addition, when the switch is positioned to either EXTEND or
RETRACT position, a signal is sent to the engine ECM to
increase engine speed above idle for operation of the
outriggers.
Center Front Stabilizer Switch
A center front stabilizer switch (2) is located on the top of the
controller. To extend the center front stabilizer, push the top
of the outrigger extend/retract switch, then push the top of
the center front stabilizer switch.
To retract the center front stabilizer, push the bottom of the
outrigger extend/retract switch, then push the bottom of the
center front stabilizer switch.
NOTE:
The center front stabilizer will retract anytime the
extend/retract switch is positioned to the retract
position.
Left Front Outrigger Switch
The left front outrigger switch (3) is located on the left side of
the controller. It is a three-position switch used to extend or
retract the left front stabilizer and extension cylinders. It must
be used in conjunction with the outrigger extend/retract
switch.
To extend the left front outrigger beam, push the top of the
outrigger extend/retract switch (1) and the top of the left front
outrigger switch.
To retract the left front outrigger beam, push the bottom of
the outrigger extend/retract switch and the top of the left front
outrigger switch.
