Abstract

Eine Einrichtung zum gegenläufigen Verschieben von paarweise angeordneten Gabelzinken (9, 10) auf Gabelträgern (4) von Flurförderzeugen mit einen Hubschlitten (1) für den Gabelträger (4) besitzt zwei Umlenkrollen (29, 30) und ein darüber geführtes Endlosglied (31) mit einem oberen Trum (32) und einem unteren Trum (35), von denen jedes formschlüssig mit jeweils einem in einer waagrechten Führung geführten Mitnehmerteil (34, 37) verbunden ist, von denen eines unmittelbar durch einen Kraftantrieb (39) verschiebbar ist. Um mit einer solchen Einrichtung auch bereits vorhandene Flurförderzeuge ohne erhebliche Umbauten und Bearbeitungsvorgänge nachrüsten zu können, ist die waagrechte Führung durch eine eigenständige Führungsschiene (28) gebildet, die auf die Oberkante des Gabelträgers (4) aufsetzbar ist und die die Umlenkrollen (29, 30) mit dem Endlosglied (31), die beiden Mitnehmerteile (34, 37) und den Kraftantrieb (39) trägt, wobei die Mitnehmerteile (34, 37) formschlüssig mit den oberen Enden der Gabelrücken (11, 12) zusammenwirken. Bevorzugt besitzt die Führungsschiene (28) einen C-förmigen Querschnitt mit einem Hohlraum und einem in Fahrtrichtung offenen, engeren Schlitz (46), und an den Mitnehmerteilen (34, 37) sind T-förmige Führungsprofile befestigt, die durch den Schlitz (46) in den Hohlraum eingreifen.

Figure 00000001
A device for oppositely displacing paired fork tines (9, 10) on fork carriers (4) of industrial trucks with a lifting carriage (1) for the fork carrier (4) has two deflection rollers (29, 30) and an endless link (31) guided over them an upper run (32) and a lower run (35), each of which is positively connected to a driver part (34, 37) guided in a horizontal guide, one of which can be moved directly by a power drive (39). In order to be able to retrofit already existing industrial trucks with such a device without significant conversions and machining operations, the horizontal guide is formed by an independent guide rail (28) which can be placed on the upper edge of the fork carriage (4) and which the deflection rollers (29, 30 ) with the endless link (31), which carries the two driver parts (34, 37) and the power drive (39), the driver parts (34, 37) interacting positively with the upper ends of the fork backs (11, 12). The guide rail (28) preferably has a C-shaped cross section with a cavity and a narrower slot (46) which is open in the direction of travel, and T-shaped guide profiles are fastened to the driver parts (34, 37) and are passed through the slot (46). engage in the cavity.
