Abstract

Die Erfindung betrifft ein Flurförderzeug (10) mit einer Lastverlagerungsvorrichtung (12, 14, 16, 18), welche zwei relativ zueinander längs einer Verlagerungsachse (V) im Wesentlichen verstellbare Vorrichtungsteile (12, 14, 19, 20) und wenigstens ein Kolben-Zylinder-System (30, 60) zur Bereitstellung einer für eine Relatiwerlagerung der Vorrichtungsteile (12, 14, 19, 20) nötigen Kraft umfasst, wobei ein Kolben (32) des Kolben-Zylinder-Systems (30, 60) mit einem der Vorrichtungsteile (14, 20) verbunden ist und ein Zylinder (34, 64) des Kolben-Zylinder-Systems (30, 60) mit dem jeweils anderen der Vorrichtungsteile (12, 19) verbunden ist. Erfindungsgemäß ist der Zylinder (34, 64) mit dem ihm zugeordneten Vorrichtungsteil (12, 19) derart starr verbunden, dass um eine in Zylinderlängsrichtung (L, L') verlaufende Torsionsachse (T) wirkende Torsionsmomente oder/und im Wesentlichen in Zylinderlängsrichtung (L, L') wirkende Zug- oder/und Druckkräfte oder/und um eine im Wesentlichen orthogonal zur Zylinderlängsrichtung (L, L') verlaufende Biegeachse (W, W') wirkende Biegemomente vom Vorrichtungsteil (12, 19) zumindest auf einen Längsabschnitt (34b) des Zylinders (34, 64), insbesondere des Zylindermantels, übertragbar sind.

The invention relates to an industrial truck (10) having a load transfer device (12, 14, 16, 18) which has two device parts (12, 14, 19, 20) which are essentially adjustable relative to one another along a displacement axis (V) and at least one piston cylinder System (30, 60) for providing a force necessary for a relative bearing of the device parts (12, 14, 19, 20) force, wherein a piston (32) of the piston-cylinder system (30, 60) with one of the device parts ( 14, 20) is connected and a cylinder (34, 64) of the piston-cylinder system (30, 60) with the other of the device parts (12, 19) is connected. According to the invention, the cylinder (34, 64) is rigidly connected to its associated device part (12, 19) in such a way that torsional moments acting about a torsion axis (T) extending in the cylinder longitudinal direction (L, L ') and / or substantially in the cylinder longitudinal direction (L L ') acting tensile and / or compressive forces and / or about a substantially orthogonal to the cylinder longitudinal direction (L, L') extending bending axis (W, W ') bending moments from the device part (12, 19) at least on a longitudinal portion (34b ) of the cylinder (34, 64), in particular of the cylinder jacket, are transferable.
