Abstract

Die Erfindung betrifft ein Hydrauliksystem mit zumindest einer Antriebsmaschine (21), insbesondere einer Pumpe, und mit wenigstens zwei Arbeitsmaschinen (4), insbesondere zwei als Hydraulikzylinder ausgebildeten Arbeitsmaschinen, wobei jede Arbeitsmaschine über zwei, je nach Betriebszustand der Arbeitsmaschine als Zulauf bzw. Rücklauf dienenden Anschlüsse (10,11) mittels entsprechender Druckleitungen mit der jeweils zugeordneten Antriebsmaschine (21) verbunden ist, und mit wenigstens einem jeder Arbeitsmaschine zugeordneten Ventil (19) zur Einstellung des Betriebszustandes der jeweiligen Arbeitsmaschine. Um ein Hydrauliksystem anzugeben, bei dem die Energie beim Einfahren, beispielsweise bei einer Hubarbeitsbühne, genutzt werden kann, soll bei zumindest einer Arbeitsmaschine derjenige Anschluss, der bei einem Betriebszustand dieser Arbeitsmaschine, welcher durch die Gravitation bewirkt oder zumindest unterstützt ist, als Ablauf dient, unter Umgehung der Antriebsmaschine über einen Bypass (17) direkt mit dem bei einem gewünschten Betriebszustand als Zulauf dienenden Anschluss einer anderen Arbeitsmaschine verbunden sein, so dass die von der ersten Arbeitsmaschine abfließende Hydraulikflüssigkeit zur Betätigung der anderen Arbeitsmaschine strömt.
