Manifold schematic
F
UNCTION
: Enables the adjustment of the horizontality
of the work platform :
- When a movement to tilt the platform to the rear is
controlled :
- The solenoid valve [EVI] is actuated.
- The coil [MB] (Jib elevation) on the function
manifold is supplied.
An additional volume of fluid is admitted in the trim
circuit between the master cylinder (rod side) and the
slave cylinder (piston side) : the work platform tilts
rearwards.
- When a movement to tilt the platform to the front is
controlled :
- The solenoid valve [EVI] is actuated.
- The coil [DB] (Jib lowering) on the function
manifold is supplied.
A volume of fluid is extracted from the trim circuit
between the master cylinder (rod side) and the slave
cylinder (piston side) : the work platform tilts forwards.
Solenoid poppet valve [EVI]
Pressure relief valve [PR1]
F
UNCTION
: Protects the trim circuit against excessive
pressure during the jib elevation movement.
Setting of the pressure relief valve
: see § 3.19.
