Description

Hublader mit dem Vorschieben des Lastträgers dienender Schere Die Erfindung bezieht sich auf einen Hublader mit einer einerseits am Hinterrahmen des Hubschlittens, andererseits am Vorderrahmen des Lastträgers angelenkten und geführten, dem Vorschieben des Lastträgers dienenden Schere, die mittels eines oben und unten an Hinterrahmen und Vorderrahmen angreifenden Hydraulikzylinders angetrieben ist.Lifting loader with scissors serving to advance the load carrier The invention relates to a lift truck with a one hand on the rear frame of the Lifting carriage, on the other hand articulated and guided on the front frame of the load carrier, for advancing the load carrier serving scissors, which by means of a top and bottom is driven on the rear frame and front frame engaging hydraulic cylinder.

Es sind Hublader bekannt, bei denen Scheren zum Vorschieben des Lastträgers benutzt werden. In den bekannten Hubladern wird mit einem oder zwei zwischen den Scheren angeordneten und zu diesen parallelen Hydraulikzylindern gearbeitet. Wie die Praxis gezeigt hat, besteht hierbei die Möglichkeit einer unerwünschten seitlichen Bewegung des Lastträgers, die zu Zerstörungen am Hublader oder dessen Umgebung führen können.There are known lifters in which scissors are used to advance the load carrier to be used. In the well-known lifters with one or two between the Scissors arranged and worked on these parallel hydraulic cylinders. As Practice has shown that there is the possibility of an undesirable lateral Movement of the load carrier, which leads to destruction of the lift truck or its surroundings can.

Die Erfindung beseitigt diesen Nachteil und verwirklicht einen Hublader, dessen Lastträger nicht von seiner geradlinigen Bewegungsrichtung abweichen kann.The invention eliminates this disadvantage and realizes a lift truck, whose load carrier cannot deviate from its rectilinear direction of movement.

Zu diesem Zweck weisen die Angriffspunkte der Hydraulikzylinder am Hinterrahmen einen größeren Abstand als am Vorderrahmen auf. Die Zylinder stehen daher geneigt zu dem Gestänge der Schere und erhöhen die Seitenstabilität des Traggerüstes und verhindern damit ein Seitwärtsschwenken des Lastträgers.For this purpose, the points of application of the hydraulic cylinder on Rear frame a greater distance than at the front frame. The cylinders are up therefore inclined to the linkage of the scissors and increase the lateral stability of the supporting structure and thus prevent the load carrier from pivoting sideways.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt. Es zeigt F i g. 1 eine Seitenansicht des Hubladers mit dem Vorschieben des Lastträgers dienender Schere, F i g. 2 eine Vorderansicht nach F i g. 1, wobei der Lastträger weggelassen ist.An embodiment of the invention is shown schematically in the drawing shown. It shows F i g. 1 is a side view of the lift truck with the advancement the load carrier serving scissors, F i g. 2 is a front view according to FIG. 1, where the load carrier is omitted.

Dem Vorschieben des Lastträgers 25 des nicht dargestellten Hubladers dient eine Doppelschere, bestehend aus den Scherengliedern 9, 10, die in Gelenken 14 miteinander verbunden und hinten an dem über Zwischenglieder 2 am Hubschlitten 1 angebrachten Hinterrahmen 7, vorn am Vorderrahmen 8 oben angelenkt sind und in deren Vertikalführungen unten mittels Rollen 13 geführt sind.The advancement of the load carrier 25 of the lift truck, not shown serves a double scissors, consisting of the scissor links 9, 10, the joints 14 connected to each other and at the rear of the via intermediate links 2 on the lifting carriage 1 attached rear frame 7, are hinged at the front of the front frame 8 above and in the vertical guides of which are guided at the bottom by means of rollers 13.

Gekreuzte Diagonalversteifungen 15 am Vorderrahmen 8 und ebensolche Diagonalversteifungen 16 an den Scherengliedern 10 dienen der Aussteifung des gesamten Getriebes.Crossed diagonal stiffeners 15 on the front frame 8 and the like Diagonal stiffeners 16 on the scissor members 10 are used to stiffen the entire Transmission.

Als Antriebe sind außen beiderseits der Rahmen 7, 8 und Scherenglieder 9, 10 zwei in gleicher Ebene wirkende Hydraulikzylinder 11, 12 angebracht, die unten am Hinterrahmen 7 angelenkt sind und mit ihren Kolbenstangen 17,18 oben am Vorderrahmen 8 ; angreifen. Dabei ist der Abstand der Anlenkpunkte der Hydraulikzylinder 11, 12 am Hinterrahmen 7 größer als der Abstand der Anlenkpunkte ihrer Kolbenstangen 17, 18 am Vorderrahmen 8, so daß die Hydraulikzylinder 11, 12 geneigt zu den Scherengliedern 9, 10 stehen und deren einseitig seitliches, elastisches Nachgeben verhindern.As drives are the outside on both sides of the frame 7, 8 and scissor links 9, 10 two hydraulic cylinders 11, 12 acting in the same plane are attached, the bottom are hinged to the rear frame 7 and with their piston rods 17,18 on top of the front frame 8th ; attack. The distance between the articulation points of the hydraulic cylinders 11 is 12 on the rear frame 7 greater than the distance between the articulation points of their piston rods 17, 18 on the front frame 8, so that the hydraulic cylinders 11, 12 are inclined towards the scissor members 9, 10 and prevent their elastic yielding on one side.
