HYDRAULIC SYSTEM

OUTRIGGER CONTROL MANIFOLD

Description

There are two outrigger control manifolds utilized on the
crane, one for the front outriggers (Figure 2-25) and one for
the rear outriggers (Figure 2-26). The front manifold consists
of five normally closed two position two way solenoid valves
and the rear 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.
