Abstract

Hydroseilaufzug, umfassend eine Antriebsvorrichtung mit einem mit einem Arbeitsfluid beaufschlagbaren Differentialzylinder (1) zum Bewegen einer Last, insbesondere einer eine Zuladung aufnehmenden Kabine, wobei der Differentialzylinder (1) in einen ein Fördermittel für das Arbeitsfluid aufweisenden Fluidkreislauf eingebunden ist und zwei Arbeitsräume (23,24) aufweist, die beide in Abhängigkeit der geforderten Bewegung mit Arbeitsfluid beaufschlagbar sind.
