Hydraulic diagram
The hydraulic control unit at the front of the baler directs the hydraulic
pressure through lines to activate functions.
The bale growth in the bale chamber extends the tension cylinders.
Hydraulic oil from the top side of the piston is pressed through an ad-
justable pressure valve and then flows back into the tension cylinders
underneath the piston.
The hydraulic control unit directs the hydraulic pressure through lines
E and D to the tailgate cylinders. When the tailgate opens the tension
cylinders move freely up. A throttle non-return valve in the hydraulic
system enables a sufficient flow in order to open the tailgate quickly.
When the tailgate is to close the hydraulic pressure is directed on top
of the tailgate cylinders: the tailgate closes. Just before the tailgate is
closed the flow changeover valve is connected in between (little flow)
and acts to brake the motion of the tailgate and at once prevents a
sudden depression in the system.
Each tailgate cylinder has a substantial shock absorber at the end of
its stroke.
