The new system "variopress and its advantages:
- Pressure adjustment of the blades during operation (e.g. via radio)
- Opening/closing the blades during operation (e.g. via radio)
- Opening/closing the blades for model transport
- Opening the blades in the event of faults
- Better debarking result through pressure adjustment of the blades
(e.g. summer / winter operation)
The function of the patented ‘variopress’ system:
The rotor itself contains a self-sufficient hydraulic unit for adjusting the knives. Driven by an electric motor, a hydraulic pump produces the pressure required to adjust the blades.
The power unit is supplied via 230V slip rings.
A directional control valve opens and closes the five cylinders of the knife arms. Five built-in diaphragm accumulators store the equalising oil for the differential cylinders. The pump draws the oil from an air-free bladder tank (when the entire rotor is rotating).
"variopress" is available for the rotor debarkers ZE 905 and ZE 1105.
