Abstract

Hydraulische Schaltungsanordnung für eine hydraulisch betriebene Arbeitsmaschine, umfassend mindestens einen hydraulischen Verbraucher zum wahlweisen Heben oder Senken einer Last, sowie eine erste und eine zweite mit dem hydraulischen Verbraucher verbundene Hydraulikleitung, wobei zum Heben der Last ein Hydraulikflüssigkeitszulauf für den hydraulischen Verbraucher über die erste Hydraulikleitung erfolgt und ein Hydraulikflüssigkeitsrücklauf von dem hydraulischen Verbraucher über die zweite Hydraulikleitung erfolgt, und wobei zum Senken der Last ein Hydraulikflüssigkeitszulauf für den hydraulischen Verbraucher über die zweite Hydraulikleitung erfolgt und ein Hydraulikflüssigkeitsrücklauf von dem hydraulischen Verbraucher über die erste Hydraulikleitung erfolgt, mindestens ein Senkensteuerventil, das in geöffnetem Zustand einen Durchfluss von beim Senken der Last als Rücklauf vom hydraulischen Verbraucher kommender Hydraulikflüssigkeit zulässt und in einem geschlossenen Grundzustand für einen solchen Durchfluss von Hydraulikflüssigkeit sperrt, mindestens ein mit der zweiten Hydraulikleitung verbundenes Vorsteuerventil, wobei durch das Vorsteuerventil ein Vorsteuerdruck an einem ersten Steuereingang des Senkensteuerventils zum Öffnen des Vorsteuerventils steuerbar ist, eine Druckmesseinrichtung, die den Druck in der zweiten Hydraulikleitung zumindest beim Senken der Last misst, und eine Regeleinrichtung, die auf Grundlage des von der Druckmesseinrichtung gemessenen Drucks das Vorsteuerventil derart zum Öffnen des Senkensteuerventils ansteuert, dass in der zweiten Hydraulikleitung ein vorgegebener Druck herrscht.
