Abstract

The truck has a mast (2) with an elevating slide (3) carrying a pair of forks (4). Also carried on the slide (3) is a second mast (5) with an elevating slide (6) carrying a second pair of forks (7). To lift a pair of boxes off the floor, the upper box is engaged using the second pair of forks and lifted. The bottom box is then lifted using the first pair of forks. During raising of the bottom box the distance between the two boxes remains unchanged. ADVANTAGE - Saves handling time.

Description

Die Erfindung bezieht sich auf einen fahrbaren Hubapparat nach dem Oberbegriff des ersten Anspruchs.The invention relates to a mobile lifting device according to the preamble of the first claim.

Aus der DE-A-35 08 194 ist ein Stapelfahrzeug bekannt, welches einen vorderen Hubmast trägt, an dem ein Hub­ schlitten verfahrbar angeordnet ist. Der Hubschlitten trägt in an sich bekannter Weise Lastgabeln, mit denen eine Last vom Boden angehoben werden kann. Weiterhin ist an dem Hubmast ein Kran angeordnet mit einer hydraulisch betriebenen Auf- und Abladevorrichtung. Damit können Ma­ terialien, die von den Lastgabeln getragen werden, be- und entladen werden.A stacking vehicle is known from DE-A-35 08 194, which carries a front mast on which a hub carriage is arranged movable. The lifting carriage carries forks in a manner known per se with which a load can be lifted off the floor. Still is a crane is arranged on the mast with a hydraulic operated loading and unloading device. Ma materials carried by the forks and be unloaded.

Aufgabe der vorliegenden Erfindung ist es, einen fahrba­ ren Hubapparat der eingangs genannten Art dahingehend weiterzubilden, daß ein Be- und Entladen von zwei übereinander stehenden Gitterboxen erleichtert wird.The object of the present invention is to provide a fahrba ren lifting apparatus of the type mentioned to further develop a loading and unloading of two stacked lattice boxes is facilitated.

Diese Aufgabe wird erfindungsgemäß durch die kennzeich­ nenden Merkmale des ersten Anspruchs gelöst. Die Verwen­ dung von zwei separat steuerbaren Hubschlitten an zwei Hubmasten gestattet es, gleichzeitig zwei übereinander gestapelte Gitterboxen zu transportieren und diese nach­ einander der gleichzeitig in ein Regal in übereinanderliegen Ebenen abzusetzen. Damit entfallen zeitaufwendige und gefahrenträchtige Rangierfahrten.This object is inventively characterized by nenden features of the first claim solved. The use of two separately controllable lifting carriages on two Lift masts allows two on top of each other at the same time stacked lattice boxes and transport them to  each other in a shelf at the same time to lay layers on top of each other. This eliminates time-consuming and dangerous shunting trips.

Die Weiterbildung nach Anspruch 2 hat den Vorteil, daß mit dem Anheben des ersten, unteren Hubschlittens gleich­ zeitig auch der weitere Hubmast mit angehoben wird, so daß der Abstand der beiden Lastgabeln gleich bleibt. Da­ durch wird verhindert, daß die auf der unteren Lastgabel deponierte Last beim Anheben von unten gegen die Lastga­ beln an dem zweiten Hubmast stoßen.The development according to claim 2 has the advantage that with the lifting of the first, lower lifting carriage the other mast is also raised at the same time that the distance between the two forks remains the same. There by preventing the on the lower fork deposited load when lifting against the load from below bump against the second mast.

Die Weiterbildung nach Anspruch 3 stellt eine einfache Nachrüstlösung dar.The development according to claim 3 is a simple one Retrofit solution.

In folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher erläutert.In the following the invention is preferred based on a Embodiment explained in more detail.

In den beiden Abbildungen ist die Seitenansicht (Fig. 1) und die Draufsicht (Fig. 2) eines handelsüblichen, fahr­ baren Gabelstaplers 1 dargestellt, welcher an seiner Frontseite einen Hubmast 2 trägt. An dem Hubmast 2 ist in üblicher Weise ein Hubschlitten 3 heb- und senkbar gela­ gert, der zwei nach vorne weisenden Lastgabeln 4 trägt. Die Lastgabeln 4 können seitlich verschiebbar angeordnet werden.In the two figures, the side view ( Fig. 1) and the top view ( Fig. 2) of a commercially available, mobile forklift truck 1 is shown, which carries a mast 2 on its front. On the mast 2 , a lifting carriage 3 is lifted and lowered gela gert in the usual way, which carries two forward-facing forks 4 . The forks 4 can be arranged laterally displaceable.

Weiterhin trägt der Hubschlitten 3 einen weiteren Hubmast 5, der wiederum mit einem Hubschlitten 6 ausgerüstet ist. Auch dieser Hubschlitten 6 ist heb- und senkbar in an sich bekannter Weise ausgebildet. Auch er trägt zwei nach vorne weisende Lastgabeln 7, die ebenfalls in an sich be­ kannter Weise seitlich verschiebbar angeordnet sind.Furthermore, the lifting carriage 3 carries a further lifting mast 5 , which in turn is equipped with a lifting carriage 6 . This lifting carriage 6 can also be raised and lowered in a manner known per se. He also carries two forward-facing forks 7 , which are also laterally displaceable in a manner known per se.

Auf beiden Lastgabeln kann je eine Gitterbox abgestellt werden. A lattice box can be placed on each of the two forks will.  

Um die Gitterboxen aufzunehmen, wird - wenn beide Gitter­ boxen auf dem Boden stehen - zuerst die obere Gitterbox aufgenommen, indem der Hubschlitten 6 in seine untere Position fährt. Nach Aufnahme der oberen Gitterbox wird der Hubschlitten 6 angehoben und sodann kann in üblicher Weise die untere Gitterbox übernommen werden. Dadurch, daß der Hubmast 5 an dem Hubschlitten 3 befestigt ist, bleibt der Abstand zwischen den Lastgabeln 4 und 7 bei einem Verfahren des unteren Hubschlittens konstant.In order to accommodate the lattice boxes, when the two lattice boxes are on the floor, the upper lattice box is first picked up by the lifting carriage 6 moving into its lower position. After picking up the upper lattice box, the lifting slide 6 is raised and then the lower lattice box can be taken over in the usual way. Characterized in that the mast 5 is attached to the lifting carriage 3 , the distance between the forks 4 and 7 remains constant when moving the lower lifting carriage.

Beide Gitterboxen können nun gemeinsam auf einen unteren und darüber liegenden Regalboden abgesetzt werden und hierzu ist nur ein einziger Arbeitsgang erforderlich.Both grid boxes can now be placed together on a lower one and shelf located above it and this requires only a single operation.

Es ist aber auch möglich, beide Gitterboxen nacheinander, z. B. auf ein Flurförderzeug, beispielsweise ein Förder­ band, abzusetzen. Hierzu wird dann zuerst die untere Git­ terbox abgesetzt und dann anschließend - nachdem diese abtransportiert wurde - die obere.But it is also possible to place both mesh boxes one after the other, e.g. B. on an industrial truck, for example a conveyor tied off. For this purpose, the lower git is first terbox and then - after this was removed - the upper one.
