Abstract

Ein Hydrauliksystem zum Anschluß an einen Stellzylinder (100) zur Eigengewichtsentlastung von sich dynamisch vertikal bewegenden Anbaugeräten, insbesondere Schneepflug, besitzt eine elektronische Regelungseinrichtung zum Einregeln des Drucks p zum Anheben des Anbaugeräts auf einen Solldruck ps, wobei die Regelungseinrichtung des weiteren dafür sorgt, daß der Druck p, wenn sich der Druck aus einem vorgegebenen Toleranzdruckbereich p1, p2 um den Solldruck ps herausbewegt, so erhöht oder erniedrigt wird, daß der Druck wieder in den Toleranzdruckbereich zurückgeführt wird.
