OUTRIGGER CONTROL MANIFOLD
Description
There are two outrigger control manifolds utilized on the
crane, one for the front outriggers and one for the rear
outriggers. The front manifold (Figure 2-12) consists of five
normally closed two position two way solenoid valves and a
200 psi check valve for the fifth jack, the rear (Figure 2-13)
consists of four normally closed two position two way
solenoid valves. They are mounted inside the frame of their
respective outrigger box.
When energized, the solenoid shifts the spool to open
allowing extension or retraction of the outrigger cylinders.
