Description

Hublader mit einem mittels Scheren vorschiebbaren Lastträger Es sind Hublader bekannt, deren Lastträger mittels Scheren waagerecht vorschiebbar sind. Dabei ist der Hubschlitten mit Rollen am Hubmast senkrecht verschiebbar geführt. Am Hubschlitten sind die Scheren angelenkt, an deren freien Enden der Lastträger angebracht ist. Die Scheren können durch eine Hydraulik bewegt werden, so daß damit der Lastträger vorgeschoben oder zurückgezogen wird. Allerdings ist bei diesen bekannten Geräten das Gewicht verhältnismäßig groß, denn außer der Schere ist ein besonderer Hubschlitten vorhanden.A lift truck with a load carrier that can be pushed forward by means of scissors There are Known lifters whose load carriers can be advanced horizontally by means of scissors. The lifting carriage is guided so that it can be moved vertically with rollers on the lifting mast. The scissors are hinged to the lifting carriage and the load carriers are attached to their free ends is appropriate. The scissors can be moved by a hydraulic system, so that with it the load carrier is advanced or withdrawn. However, this is well known Devices the weight is relatively large, because apart from the scissors is a special one Lifting carriage available.

Der Erfindung liegt die Aufgabe zugrunde, bei Hubladern die Einrichtungen zum Vorschieben von Lastträgern mittels Scheren durch Einsparen schwerer Bauteile leichter und einfacher zu gestalten.The invention is based on the object of the devices in the case of lift trucks for advancing load carriers using scissors by saving heavy components easier and simpler to design.

Die Lösung besteht darin, daß die Scheren an ihren inneren Gliedenden mit Rollen versehen und hiermit in den Schienen des Hubmastes geführt sind. Damit entfällt der zusätzliche Schlitten, den nunmehr die inneren Enden der Scheren verwirklichen.The solution is to hold the scissors at their inner limb ends are provided with rollers and are thus guided in the rails of the lifting mast. In order to the additional slide that is now realized by the inner ends of the scissors is no longer necessary.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

In den Schienen 1 des Hubmastes sind senkrecht verschiebbar Rollen 2 und 3 geführt, die an den inneren Enden von zwei nebeneinander angeordneten Scheren angebracht sind. Die beiden Glieder 4, 5 beider Scheren sind auf einer gemeinsamen, drehsteifen Welle 6 derart gelagert, daß mindestens eines der beiden Gliedpaare 4 oder 5 die gleichen Winkelbewegungen ausführt und damit asymmetrische Belastungen aufgenommen werden können. An den Armen 4 greift die Kette 7 an, die zum Heben der Scheren und damit des Lastträgers dient.Rollers are vertically displaceable in the rails 1 of the lifting mast 2 and 3 out, the at the inner ends of two juxtaposed scissors are appropriate. The two links 4, 5 of both scissors are on a common, torsionally rigid shaft 6 mounted in such a way that at least one of the two pairs of links 4 or 5 performs the same angular movements and thus asymmetrical loads can be included. On the arms 4, the chain 7 engages, which is used to lift the Scissors and thus the load carrier is used.

Die äußeren Enden 8 der Glieder 5 sind am Rahmen 9 des Lastträgers 10 artgelenkt. Dagegen sind die äußeren Enden der Glieder 4 mit Rollen 11 versehen, die sich im Rahmen 9 verschieben können. Zwischen den inneren Schenkeln der Gliedpaare 4 und 5 ist ein. Hydraulikzylinder 12 angeordnet, durch dessen Betätigung die Scheren, wie strichpunktiert eingezeichnet, gestreckt werden. Der Hydraulikzylinder 12 kann auch zwischen den äußeren Schenkeln der Gliedpaare 4 und 5 angeordnet sein, wie gestrichelt eingezeichnet ist.The outer ends 8 of the links 5 are on the frame 9 of the load carrier 10 articulated. In contrast, the outer ends of the links 4 are provided with rollers 11, which can move in frame 9. Between the inner legs of the link pairs 4 and 5 is a. Hydraulic cylinder 12 arranged, by actuating the scissors, as drawn in dash-dotted lines, are stretched. The hydraulic cylinder 12 can also be arranged between the outer legs of the link pairs 4 and 5, such as is shown in dashed lines.
