vehicles are equipped with a proportional valve (see Figure 5
4), as part of
the
arm vane pump, that powers all arm functions (gripper [open/close], lifting arm [extend/retract,
up/down]). It can also power an optional crusher panel with the addition of another valve section.
The amount of flow coming out of this valve varies according to the position of the spool. This
feature, called proportional control, allows infinite control of the speed at which the arm goes up and
down, extends and retracts.
Each section of this valve is actuated by an electric coil located on the side of the valve.

4 Proportional valve
•
Input/output cover: provided with main relief valve
•
Gripper section (open/close): not proportional, with load sensor relief
•
Lifting arm section (extend/retract): proportional, no load sensor relief
•
Lifting arm section (up/down): proportional, no load sensor relief
Inspecting the Pump
The hydraulic pump is powered by the vehicle engine through a drive shaft or by an optional PTO.
The pump should be visually inspected every working day.

:
On some units, the pump is directly installed on a PTO with no drive shaft.
