Abstract

Die Erfindung betrifft einen Verriegelungszylinder (20) mit einem Zylinder (21) und einem Kolben (22), der mithilfe eines Druckmittels längs des Zylinders (21) bewegbar ist. Der Kolben 22 steht über ein nicht selbsthemmendes Gewinde (37) in Eingriff mit einer Spindel (35). Diese weist wenigstens eine Verriegelungsausnehmung (38) auf, in die ein oder mehrere Verriegelungsbolzen (40) federkraftbeaufschlagt eingreifen kann bzw. können und dadurch in eine Verriegelungsstellung überführbar ist bzw. sind, in welcher er bzw. sie in die Verriegelungsausnehmung bzw. in die Verriegelungsausnehmungen (38) der Spindel (35) eingreift bzw. eingreifen. Das Druckmittel ist beiden Seiten (44, 46) des Kolbens und außerdem dem bzw. den Verriegelungsbolzen (40) zuführbar. Die Verriegelungsbolzen (40) können separat beweglich sein. Ferner kann die Spindel (35) in Axialrichtung beweglich und federgelagert sein. Außerdem können Lasthalte-Senkbrems-Mittel (150) eingesetzt sein, mit denen ein unkontrolliertes Voreilen des Kolbens (22) vermieden werden kann und die in einer Haltestellung eine hydraulische Sicherung des Kolbens (22) in der gewünschten Hubstellung bewirken können.
