Solenoid valve 4-way, 2-position
F
UNCTION
: Allows the change in drive speed by placing
the "cyl. B" displacement of the wheel motors in "free
wheel".
- When the solenoid valve is not actuated (
and
), both motor displacementss (cyl. A +
cyl. B) are supplied.
[ HI ] : High displacement
Ô
slow speed
- When the solenoid valve is actuated (
), only
the motor displacement "cyl. A" is supplied,
displacement "Cyl. B" is placed in "free wheel".
[ LO] : Low displacement
Ô
high speed

Counterbalance valves
F
UNCTION
: Allows dynamic braking of the work
platform and the counter pressure necessary for the
make up flow to the wheel motors.
Counterbalance valve setting
: The tighter the
setting screw is, the sharper is the braking of the
work platform.
Adjustment must be done with the rated load correctly
distributed in the work platform. Tighten completely
the setting screw, then loosen by 4 1/2 turns to obtain
an average setting.
Sharpen the setting if necessary so that :
- When the work platform is driven at maximum
speed, it stops over a distance of 0,8m to 1m on
horizontal ground (in both drive directions) when
the joystick is returned to its neutral position.
- When the work platform is driven down a 15% slope
in 2nd gear, it stops over a distance below 1 m
when the joystick is returned to its neutral position.
Shuttle valve
F
UNCTION
: Oil supply to the brake release circuit in
both drive directions of the work platform.
