Abstract

Bei einem Flurförderzeug mit einer Kolben-Zylinder-Anordnung (20), umfassend einen Zylinder (26) und einen aus diesem ausfahrbaren und in diesen einfahrbaren Kolben (22), als Antrieb oder/und Führung eines ersten Bauteils (12) zur Bewegung relativ zu einem zweiten Bauteil (14), insbesondere als Antrieb von Bauteilen (12, 4) eines Hubsystems (10) ist der Kolben (22) mit einem ihm zugeordneten Bauteil (14): erstes oder zweites Bauteil, zur Kraftübertragung gekoppelt und ist der Zylinder (26) an einem Zylinderlager (34) des jeweils anderen, dem Zylinder (26) zugeordneten Bauteils (12) gelagert und zur Kraftübertragung mit diesem gekoppelt. Der Zylinder (26) befindet sich derart in Anlageeingriff mit dem Zylinderlager (34), dass er relativ zu dem Zylinderlager (34) beweglich ist.

In an industrial truck with a piston-cylinder arrangement (20), comprising a cylinder (26) and a retractable and retractable in this piston (22), as a drive and / or guide a first component (12) for movement relative to a second component (14), in particular as drive of components (12, 4) of a lifting system (10), the piston (22) is associated with a component (14) assigned to it: first or second component, for transmitting power and is the cylinder ( 26) mounted on a cylinder bearing (34) of the other, the cylinder (26) associated with the component (12) and coupled to the power transmission with this. The cylinder (26) is in abutting engagement with the cylinder bearing (34) such that it is movable relative to the cylinder bearing (34).
