REAR OUTRIGGERS (RSOD)
The Rear Stabilizer Out and Down (RSOD) (Figure 7-8) is
located behind the rear wheels and provides added stability
for the crane. The RSOD can be used in the fully retracted, at
the mid-extended, or the fully extended positions.
The RSOD is controlled with the hand held outrigger control
box located in a compartment on the operator control
console. When the outrigger extension is activated the
selected beam or stabilizer is extended or retracted.
RSOD Assembly
The RSOD assembly consists of the following:
• outrigger beams
• jacks
• required hoses and mounting hardware
• OMS potentiometer and associated hardware (if
equipped)
Removal
1. Check that the stabilizer is fully retracted.
2. Extend the outrigger beam slightly so that a lifting strap
(Figure 7-4) can be attached to the outrigger beam.
NOTE: To prevent damage to the bottom of the outrigger
beam, do not attach chains to the outrigger beam.
3. Tag and remove the hydraulic hoses connected to the
extension (5, Figure 7-9) and stabilizer (7) cylinders.
4. Remove the bolts (1) that attach the extension cylinder
barrel to the outrigger box.
5. Pull the outrigger beam out of the outrigger box with the
lifting device.
6. Position the outrigger beam on blocking material
(Figure 7-4).
Inspection
Inspect the outrigger beam for bends, evidence of cracks, or
other damage. Check the outrigger beam internally for
hydraulic fluid, which may indicate a leaking cylinder, loose
connection, or damaged hydraulic line.
Installation
1. Apply grease (EP-MPG) to the bottom of the outrigger
beam.
2. Slide the beam into the outrigger box.
3. Bolt the extension cylinder to the end of the outrigger
box.
