Hydraulics QUANTUM TIC
11-82 10/04
4.2.5 Raise pick-up Solenoid valve (12-M4) and solenoid valve (31) are activated.
The volume flow from the pump (10 l/min.) flows to the hydraulic cylinders
(35) via port A of solenoid valve (12) and from there via solenoid valve
(31).
The backside build-up of pressure moves the spool (5) of circulation
valve (4) back against the volume flow from the pump.
The pick-up is raised.
When the hydraulic cylinders hit their limit stop, the pressure relief valve
(8) opens. The spool (5) of the circulation valve (4) opens and the volume
flows back into the tank via the circulation valve (4).
When switching off, the solenoid valves (31) and, after a delay, solenoid
valve (12-M4) are switched off first.
4.2.6 Pick-up lower The solenoid valve (31) is actuated.
The displaced oil from the hydraulic cylinders (35) flows back to the tank
via the activated solenoid valve (31). The pick-up is lowered.
4.2.7 Floating position The solenoid valve (31) is actuated.
In the floating position, the pick-up follows the ground contours so that
the hydraulic cylinders (35) are raised or lowered.
Oil is either taken in or displaced by the activated solenoid valve (31) and
the deenergized solenoid valve (12).
A control light (green) in the control box indicates that the pick-up has
been lowered (floating position).
