Abstract
Description
Die Erfindung betrifft einen teleskopierbaren Kranausleger, mit einem rohrförmigen Basisauslegerkasten und mindestens einem Auslegerkasten, der innerhalb des Basisauslegerkastens teleskopierbar angeordnet ist, sowie einem Kopf mit Umlenkrollen am außenseitigen Ende des innersten Auslegerkastens.The invention relates to a telescopic boom, comprising a tubular base boom box and at least one boom box telescopically disposed within the base boom box, and a head having pulleys at the outboard end of the innermost boom box.
Das Gesamtgewicht eines Mobilkrans mit Teleskopausleger, der für den öffentlichen Straßenverkehr zugelassen ist, wird durch die zulässige Achslast (z.B. 12 t in Deutschland) und der Anzahl der Achsen festgelegt. Teile des Krans, wie Gegengewicht und Hauptauslegerverlängerung, müssen oftmals getrennt transportiert werden, um innerhalb der zulässigen Achslasten zu bleiben. Auch die Länge des Teleskopauslegers, der aus biegesteifen Blechkästen besteht, schränkt die Transportmöglichkeiten und das maximal erlaubte Gewicht pro Einheit ein. Eine \/orrichtung gemäss dem Obergegriff des Anspruchs 1 ist aus
Der letzte Innenkasten, also der innerste Auslegerabschnitt, trägt am vorderen Ende einen Kopf mit einem Rollensatz zum Einscheren des Hubseils, zur Umlenkung des Hubseils (Einlaufrolle) und eventuell Befestigungspunkte für eine Hauptauslegerverlängerung sowie für eine Auslegerabspannung. Der Kopf ist in den Querschnitt des Kastens hineingebaut und verschließt diesen zum großen Teil durch Stahlbauteile und Montageteile, die außer'durch komplette Demontage des Innenkastens nicht entfernt werden können.The last inner box, so the innermost boom section carries at the front end a head with a set of rollers for shearing the hoist, for the deflection of the hoist rope (inlet roller) and possibly attachment points for a main boom extension and a boom bracing. The head is built into the cross-section of the box and closes it largely by steel components and mounting hardware, which can not be removed except by completely disassembling the inner box.
Will man den Teleskopausleger durch zusätzliche Innenkästen verlängern, sind diese getrennt zu transportieren und auf der Baustelle zu montieren. Hierzu muss der bis dahin innerste Auslegerkasten mit dem Kopf zuerst entfernt werden. Anschließend muss ein Kasten ohne kopf aber mit gleichem Querschnitt und vorderer Lagerung, ggf. mit zusätzlichen weiteren inneren Auslegerkästen, eingeschoben werden.If you want to extend the telescopic boom by additional inner boxes, these are to be transported separately and mounted on the site. For this, the hitherto innermost boom box must first be removed with the head. Subsequently, a box without head but with the same cross-section and front storage, possibly with additional additional inner boom boxes inserted.
Nachteilig ist, dass man den innersten Auslegerkasten, mit dem daran angeordneten Kopf und dem zugehörigen Rollensatz erst demontieren muß, aber beim Langausleger nicht weiter verwenden kann, so dass für eine Verlängerung zwei Kästen mit gleichem Querschnitt benötigt werden. Ein Kasten bleibt nach der Verlängerung nutzlos übrig.The disadvantage is that you have to disassemble the innermost boom box, with the head arranged thereon and the associated set of rollers only, but can not continue to use the long boom, so that two boxes with the same cross section are needed for an extension. A box remains useless after the extra time.
Der Erfindung liegt die Aufgabe zugrunde, den Demontage- bzw. Montageaufwand bei einem Umbau eines Auslegers zu einem längeren Ausleger zu verringern und einen nach dem Umbau übrigbleibenden und an dieser Stelle überflüssigen Auslegerkasten zu vermeiden.The invention has for its object to reduce the disassembly or assembly effort in a conversion of a boom to a longer boom and to avoid a remaining after the conversion and unnecessary at this point boom box.
