Die Erfindung betrifft ein mindestens eine vertikal bewegbare Lastaufnahmeeinrichtung aufweisendes Hubgerüst mit mindestens einem Anschlag, der den Bewegungsweg der Lastaufnahmeeinrichtung begrenzt.The invention relates to at least one vertically movable load suspension device having mast with at least one stop that the movement of the Load handling device limited.

Im Stand der Technik bekannte Hubgerüste weisen in der Regel einen aus mehreren Teilen bestehenden Anschlag auf. Eine Anschlagplatte wird durch Unterlegen von ein oder mehreren Nachstellplatten in der Höhe verstellt. Der Anschlag ist vor allem als Begrenzung der Absenkbarkeit der Lastaufnahmeeinrichtung notwendig. Der Anschlag muß höhenverstellbar sein, da durch Abnützung der Reifen, durch Wechsel der Bereifungsart oder z.B. durch den Einsatz verschiedener Lastaufnahmeeinrichtungen eine Notwendigkeit der Anpassung des minimalen Abstands zum Boden, sowie ggf. zur Decke, besteht. Diese Anpassung ist jedoch mit den herkömmlich gestalteten Anschlägen arbeits- und zeitintensiv, da die mitgeführten Nachstellplatten zunächst aus ihrer Transportposition ausgebaut werden müssen. Dann müssen sie unter der Anschlagplatte angebracht werden. Und erst nach diesen Arbeitsschritten kann der Betrieb des Hubgerüsts wieder aufgenommen werden. Insbesondere tritt die Notwendigkeit zur Ein- und Nachstellung der Höhe des Anschlags bei Hubgerüsten für Flurförderzeuge auf.Masts known in the prior art generally have one of several Share existing stop.

Die Figuren 1 bis 6 zeigen ein erfindungsgemäßes Hubgerüst in Teildarstellung mit drei verschiedenen Positionen des Anschlagteils, jeweils in Frontalansicht mit einem Ausbruch zur Darstellung des Anschlagteils und in Schnittdarstellung von der Seitenansicht. Die Figuren 1 und 2 zeigen das Anschlagteil 1 in Grundstellung, die Figuren 3 und 4 in einer ersten möglichen Nachstellposition und die Figuren 5 und 6 in einer zweiten möglichen Nachstellposition. Die folgenden Merkmale sind in allen sechs Figuren dargestellt:Figures 1 to 6 show a mast according to the invention in partial representation with three different positions of the stop part, each in a front view with a Outbreak to show the stop part and in a sectional view of the Side view. Figures 1 and 2 show the stop part 1 in the basic position, the Figures 3 and 4 in a first possible readjustment position and Figures 5 and 6 in a second possible readjustment position. The following features are common to all six Figures shown:

Ein erfindungsgemäßes Anschlagteil 1 ist über ein Kraftaufnahmeteil 2 am Fahrmast 3 befestigt, welcher relativ zu einem Standmast 7 in vertikaler Richtung bewegbar ist. Darüber hinaus ist ein mit dem Gabelträger 4 verbundener Klotz 5 vorgesehen, der bei einer Absenkung des Gabelträgers 4 auf seine minimal einstellbare Höhe über dem Boden am Anschlagteil 1 anschlägt. Dadurch wird der Bewegungsweg des Gabelträgers nach unten wirksam begrenzt. Das Anschlagteil 1 ist in diesem Beispiel so geformt, daß die Höhe des Anschlags durch Drehung des Anschlagteils 1 um jeweils 90° auf unterschiedliche Niveaus einstellbar ist. Die in den Figuren 1 und 2 gezeigte Grundstellung des Anschlagteils 1 geht durch Drehung um 90° in die in den Figuren 3 und 4 gezeigte erste Nachstellposition über. Durch eine weitere Drehung um 90° ist die zweite Nachstellposition erreichbar, wie sie in den Figuren 5 und 6 gezeigt ist.A stop part 1 according to the invention is on the mast 3 via a force absorption part 2 attached, which is movable relative to a mast 7 in the vertical direction. In addition, a block 5 connected to the fork carriage 4 is provided, which at a lowering of the fork carriage 4 to its minimum adjustable height above the Strikes the bottom of the stop part 1. This will move the Fork carrier effectively limited downwards. The stop part 1 is in this example shaped so that the height of the stop by rotating the stop part 1 can be adjusted to different levels by 90 °. The in Figures 1 and 2 shown basic position of the stop part 1 is by rotating through 90 ° in the Figures 3 and 4 shown first readjustment position. By another turn The second readjustment position, as shown in FIGS. 5 and 6, can be reached at 90 ° is.

Das Anschlagteil 1 weist in diesem Beispiel eine im wesentlichen quaderförmige Form mit einer Aussparung auf, durch die ein Absatz gebildet wird, der die Kraft, die auf den Anschlag wirkt, auf das Kraftaufnahmeteil 2 und somit auf den Fahrmast 3 überträgt. Das so gestaltete Anschlagteil 1 weist eine exzentrische Bohrung auf, durch die hindurch eine Schraube 6 das Anschlagteil 1 am Kraftaufnahmeteil 2 befestigt. Die Schraube 6 bildet die Drehachse, um die das Anschlagteil 1 drehbar ist. Der maximale Verstellweg der Höheneinstellung des Anschlags kann wie folgt ermittelt werden: Vom größten Abstand der Drehachse zu einer zur Drehachse parallelen Seitenfläche des im wesentlichen quaderförmigen Anschlagteils 1 wird der kleinste Abstand der Drehachse zu einer solchen Seitenfläche subtrahiert. Die Differenz stellt den maximal möglichen Verstellweg der Höheneinstellung des Anschlags dar.The stop part 1 has a substantially cuboid shape in this example with a recess through which a paragraph is formed, the force acting on the Stop acts, transmits to the force receiving part 2 and thus to the mast 3. The stop part 1 designed in this way has an eccentric bore through which through a screw 6 the stop part 1 attached to the force receiving part 2. The Screw 6 forms the axis of rotation about which the stop part 1 can be rotated. The maximum Adjustment of the height adjustment of the stop can be determined as follows: From greatest distance of the axis of rotation to a side surface parallel to the axis of rotation of the im essential cuboid stop part 1 becomes the smallest distance of the axis of rotation subtracted to such a side surface. The difference represents the maximum possible Adjustment path of the height adjustment of the stop.

Es existieren eine Reihe weiterer zweckmäßiger Ausführungsformen der Erfindung. Beispielhaft sei hier genannt, daß es eine ebenfalls vorteilhafte Variante darstellt, das Anschlagteil mit dem Gabelträger sowie den Klotz mit dem Fahrmast zu verbinden. Auch gibt es viele Geometrien, die sich als Form für das Anschlagteil eignen. Diese Geometrien werden im wesentlichen bevorzugt durch die Merkmale aus Anspruch 6 gekennzeichnet.There are a number of further expedient embodiments of the invention. As an example, it should be mentioned here that it also represents an advantageous variant, that To connect the stop part with the fork carriage and the block with the mast. There are also many geometries that are suitable as a shape for the stop part. This Geometries are essentially preferred by the features from claim 6 characterized.
