Description
Die Erfindung betrifft einen Lastarm für Hubwagen, wobei der Lastarm ein C-förmiges Profil mit einer horizontalen Tragwand und zwei daran anschließenden vertikalen Seitenwänden aufweist, die Tragwand und die Seitenwände einstückig geformt sind und jeweils die Seitenwand zumindest auf einem Teilbereich der Längserstreckung des Lastarms durch eine Verstärkungswand verdickt ist.The The invention relates to a load arm for pallet trucks, wherein the load arm a C-shaped Profile with a horizontal support wall and two adjacent vertical sidewalls has, the support wall and the side walls are integrally formed and respectively the side wall at least on a partial region of the longitudinal extent of the load arm through a reinforcement wall thickened.
Derartige Lastarme werden paanrweise in Lagertechnikgeräten, wie z.B. in Palettenhubwagen und in Hochhubwagen eingesetzt. Lastarme, die mit einem anhebbaren Rahmenteil eines Lagertechnikgeräts verbunden sind, werden auch als Tragarme bezeichnet. Dies ist beispielsweise bei Palettenhubwagen der Fall. Auch in Hochhubwagen gibt es solche Tragarme. Darüber hinaus sind Hochhubwagen mit Lastgabeln ausgestattet, die an einem Hubgerüst auf- und abbewegbar sind und in vielen Fällen nicht als Schmiedeteile sondern als Blechteile ausgebildet sind, die im abgesenkten Zustand die Tragarme übergreifen, also ebenfalls eine Tragwand und zwei damit verbundene Seitenwände aufweisen.such Load arms are sometimes used in warehouse equipment, such as in pallet trucks and used in stackers. Load arms, with a liftable frame part a warehouse equipment are also referred to as support arms. This is for example for pallet trucks the case. Also in stackers there are such Carrying arms. About that In addition, pallet trucks are equipped with load forks, which on a Mast up and are movable and in many cases not as forgings but are designed as sheet metal parts, which in the lowered state overlap the brackets, So also have a support wall and two associated side walls.
Ein Lastarm besteht herkömmlicherweise aus mehreren Einzelteilen, die durch Schweißen miteinander zu einem Ganzen verbunden sind. Die vertikalen Seitenwände werden also an die horizontale Tragwand angeschweißt. Daran anschließend sind bestimmte Nacharbeiten erforderlich. Ein Lastarm, bei dem die Seitenwände und die Tragwand aus einem Stück bestehen, wobei an die Seitenwände jeweils eine Verstärkungswand aufgeschweißt ist, ist beispielsweise aus dem DE-GM 75 40 104 bekannt.One Load arm is conventionally made several parts, which by welding together into a whole are connected. The vertical side walls are thus to the horizontal support wall welded. After that certain rework is required. A load arm in which the side walls and the supporting wall in one piece exist, with the side walls one reinforcing wall each welded is, for example, from DE-GM 75 40 104 known.
Der Erfindung liegt die Aufgabe zu Grunde, einen Lastarm der eingangs genannten Art zur Verfügung zu stellen, der auf einfachere Art und Weise herstellbar ist.Of the Invention is based on the object, a load of the beginning mentioned type available to provide, which can be produced in a simpler manner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verstärkungswand jeweils einstückig mit der Seitenwand geformt und durch Umbiegen einer Seitenwandverlängerung hergestellt ist. Gegenüber der zum Schweißen erforderlichen Zeit ergibt sich eine nur kurze Bearbeitungszeit. Ein Nacharbeiten, wie dies bei der Herstellung durch Schweißen erfolgt, um den beim Schweißen eingetretenen Verzug des Lastarms durch einen Richtvorgang zu beseitigen und um die Schweißnähte von Schlacke zu säubern, ist nicht erforderlich. Bei der Verwendung von Lastarmen als Tragarme eines Palettenhubwagens, müssen sogenannte Tragrollen im Endbereich der Tragarme befestigt werden. Zu diesem Zweck sind Verstärkungen der Seitenwände erforderlich, die üblicherweise aus an der Innenseite der Lastarme angeschweißten Blechstreifen bestehen. Erfindungsgemäß ist vorgeschlagen, die Verstärkungswand jeweils einstückig mit der Seitenwand zu formen und durch Umbiegen einer Seitenwandverlängerung herzustellen. Auf diese Weise erübrigt sich jeglicher Schweißvorgang bei der Herstellung der Lastarme.These Task is inventively characterized solved, that the reinforcing wall each in one piece formed with the side wall and by bending over a side wall extension is made. Across from the one for welding required time results in only a short processing time. A rework, as is done in the production by welding, around the welding to eliminate the distortion of the load arm caused by a straightening process and around the welds of slag to clean up, not necessary. When using load arms as support arms of a pallet truck so-called support rollers are mounted in the end region of the support arms. For this purpose are reinforcements the side walls required, usually consist of welded on the inside of the load arms metal strips. According to the invention, it is proposed the reinforcement wall each in one piece to shape with the sidewall and by bending a sidewall extension manufacture. In this way is unnecessary any welding process in the manufacture of the load arms.
Zweckmäßigerweise ist die Verstärkungswand zur Innenseite des Lastarms umgebogen.Conveniently, is the reinforcement wall bent to the inside of the load arm.
