Abstract

Es wird eine hydraulische Anordnung (10) für eine Schwimmstellung beschrieben. Die Anordnung (10) umfasst einen eine erste und eine zweite Kammer (28, 30) aufweisenden Hydraulikzylinder (26), einen Hydrauliktank (20), ein eine Hydraulikflüssigkeit förderndes Fördermittel (18), eine zwischen erster Kammer (28) und zweiter Kammer (30) angeordnete Hydraulikleitung (46), ein in der Hydraulikleitung (46) angeordnetes Schaltventil (50), eine in der Hydraulikleitung (46) angeordnete volumenstromabhängig steuernde Ventilvorrichtung (52, 76), eine erste Versorgungsleitung (22) für die erste Kammer (28), eine zweiten Versorgungsleitung (24) für die zweite Kammer (30), eine in der ersten Versorgungsleitung (22) angeordnete Rohrbruchsicherungseinrichtung (32) und ein Steuergerät (12) mit wenigstens drei Schaltstellungen, welche eine Hebestellung, eine Senkstellung und eine Neutralstellung für den Hydraulikzylinder (26) umfassen. Um eine Schwimmstellungsfunktion zu ermöglichen, wird vorgeschlagen, das Steuergerät (12) mit einer weiteren Schaltstellung zu versehen, welche eine Schwimmstellung darstellt, in welcher durch das Steuergerät (12) wenigstens die zweite Versorgungsleitung (24) mit dem Hydrauliktank (20) verbindbar ist und gleichzeitig Verbindungen beider Versorgungsleitungen (22, 24) zum Fördermittel (18) unterbrochen sind.
