OUTRIGGER MANIFOLDS
There are two outrigger manifolds located on the carrier
frame. The front outrigger manifold is mounted on the center
of the front outrigger box (Figure 3-6) and the rear outrigger
manifold is mounted at the rear of the truck under the T-box
(Figure 3-7).
The swing and outrigger functions are on the same hydraulic
circuit however, only one function at a time can be working.
When the crane function power switch is turned ON, the
outrigger manifolds are disabled.
.
Front Outrigger Manifold
The solenoids on the front outrigger manifold control the
selection of the front outrigger components, single front
outrigger (SFO), the extend and retract functions of all
outrigger components, and the hydraulic flow to the outrigger
hydraulic circuit.
The solenoids on the front outrigger manifold provide the
following functions:
NOTE: When the crane function power switch in the crane
cab console is turned ON, all outrigger functions
• The SFO (3) solenoid extends or retracts the SFO when
energized. Any time the retract switch on the outrigger
control is depressed, the SFO is first up.
• The component solenoids (2 through 5) control the front
outrigger components. See Figure 3-6 for solenoid
identification.
• The extend (7) retract (8) solenoids control the extend
and retract functions for all outrigger components on
both front and rear outriggers.
Rear Outrigger Manifold
The solenoids on the rear outrigger manifold control the
selection of the rear outrigger components. See Figure 3-7
(1 through 4) for solenoid identification.
