Abstract
Description
Die Erfindung betrifft einen Teleskopkran mit wippbarem Hilfsausleger gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a telescopic crane with luffing jib according to the Preamble of claim 1.
Die Anordnung eines wippbaren Hilfsauslegers an den Hauptausleger eines Teleskopkranes ist bekannt (siehe hierzu Auszüge aus dem Prospekt Mannesmann Demag Fördertechnik, Demag AC 1600, S. 5, 24, April 96). Je nach Anforderung können bei der Anordnung mit einem wippbaren Hilfsausleger ein oder zwei Wippstützen vorgegeben sein. Die schwenkbare Anbindung des Fußstückes des Hilfsauslegers sowie der Wippstützen kann direkt am Kopf des innersten Schusses des Hauptauslegers erfolgen oder es wird ein Adapter dazwischengesetzt.The arrangement of a luffing jib on the main boom of a Telescopic cranes are known (see extracts from the Mannesmann brochure Demag conveyor technology, Demag AC 1600, p. 5, 24, April 96). Depending on requirements can with the arrangement with a luffing jib one or two Rocker supports must be specified. The swiveling connection of the foot piece of the Auxiliary boom and the luffing supports can be directly on the head of the innermost shot the main boom or an adapter is placed in between.
Bei hochliegenden Störkanten ist der Einsatz der bekannten Teleskopkrane mit Hilfsausleger begrenzt, da in diesem Fall der Teleskopkran weiter vom Hindernis entfernt aufgestellt werden muß und der Hilfsausleger entsprechend lang ist, um an der Störkante vorbei auf der Rückseite des Hindernisses die Last bewegen zu können. Der erforderliche lange Hilfsausleger vermindert entsprechend die Tragkraft des Kranes.The known telescopic cranes are used for high-lying interfering edges Auxiliary boom limited, because in this case the telescopic crane is further from the obstacle must be placed away and the auxiliary boom is long enough to the interfering edge past the rear of the obstacle to move the load can. The required long auxiliary boom reduces the load capacity accordingly of the crane.
Aufgabe der Erfindung ist es, einen Teleskopkran mit einem wippbaren Hilfsausleger anzugeben, der auch bei hochliegenden Störkanten mit hoher Tragkraft betrieben werden kann.The object of the invention is to provide a telescopic crane with a luffing jib to be specified, which is also operated with high load-bearing capacity at high lying interference edges can be.
Diese Aufgabe wird ausgehend vom Oberbegriff in Verbindung mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.This task is based on the generic term in conjunction with the characterizing features of claim 1 solved.
Kernpunkt der Erfindung ist die Anordnung eines eine Winkeleinstellung ermöglichenden Zwischengliedes am Kopfstück des wippbaren Hilfsauslegers, so daß die Befestigung einer abgewinkelten Gitterspitze möglich ist. Das Zwischenglied kann ein Adapter, eine Zugstange oder eine Kolben-Zylindereinheit sein. Durch die Wahl der Länge der Zugstangen bzw. durch die Verwendung längenveränderbarer Zugstangen kann der Grad der Abwinkelung festgelegt werden. Diese Anordnung hat den Vorteil, daß damit der Abstand des Teleskopkranes zum Hindernis gering gehalten und die Tragkraft gegenüber der bekannten Anordnung gesteigert werden kann. Außerdem ist damit der Einsatz von kürzeren Hilfsauslegern möglich.The crux of the invention is the arrangement of an angular setting enabling intermediate link on the headpiece of the luffing jib, so that the attachment of an angled lattice tip is possible. The pontic can be an adapter, a pull rod or a piston-cylinder unit. Through the Choice of the length of the tie rods or by using length adjustable The degree of angulation can be determined using tie rods. This arrangement has the advantage that the distance of the telescopic crane to the obstacle is small kept and the load capacity compared to the known arrangement can be increased can. In addition, the use of shorter auxiliary booms is possible.
In der einzigen Figur wird anhand eines Ausführungsbeispieles der erfindungsgemäß ausgebildete Teleskopkran mit einem wippbaren Hilfsausleger näher erläutert.In the single figure, an exemplary embodiment of the invention trained telescopic crane with a luffing jib explained.
In der einzigen Figur ist als Prinzipbild die erfindungsgemäße Anordnung einer abgewinkelten Gitterspitze an einem wippbaren Hilfsausleger dargestellt. An der Einsatzstelle ist ein bereits voll austeleskopierter Teleskopkran angeordnet, dessen Hauptausleger 1 einen Grundausleger 2 und vier Teleskopschüsse 3-6 aufweist. Am Kopfstück 7 des innersten Schusses 6 ist ein Adapter 14 angeordnet. An diesen Adapter 14 ist zum einen das Fußstück 15 des Hilfsauslegers 16, sowie zwei Wippstützen 17, 18 befestigt. Erfindungsgemäß sind am Kopfstück 9 des Hilfsauslegers 16 ein eine Winkeleinstellung ermöglichendes Zwischenglied 10 angeordnet, das eine Anbindung einer abgewinkelten Gitterspitze 11 ermöglicht. An der Spitze ist eine Kopfrolle 12 vorgesehen, über die das Lastseil 13 geführt ist.In the single figure, the arrangement according to the invention of an angled lattice tip on a luffing jib is shown as a basic diagram. An already fully telescopic telescopic crane is arranged at the place of use, the main boom 1 of which has a basic boom 2 and four telescopic sections 3-6 . An adapter 14 is arranged on the head piece 7 of the innermost shot 6 . The foot piece 15 of the auxiliary boom 16 and two luffing supports 17 , 18 are attached to this adapter 14 . According to the invention, an intermediate member 10 , which enables an angle adjustment and which enables an angled lattice tip 11 to be connected, is arranged on the head piece 9 of the auxiliary boom 16 . At the top a head roller 12 is provided, over which the load cable 13 is guided.
Um den Unterschied zur bekannten Anordnung gemäß dem Stand der Technik hervorzuheben, wurde in die Figur auch ein üblicher Hilfsausleger 21 mit eingezeichnet. Außerdem ist zum besseren Verständnis ein Hindernis mit hoher Störkante in Form eines fiktiven Hochhauses 20 dargestellt. Die Darstellung zeigt deutlich, daß man bei der üblichen Anordnung eines Hilfsauslegers 21 an der Störkante 22 des Hochhauses 20 nicht vorbeikäme. Dazu müßte man den Teleskopkran sehr weit vom Hochhaus 20 entfernt aufstellen, was von den Platzverhältnissen her bei enger Bebauung im Innenstadtbereich meistens gar nicht möglich ist, und der Hilfsausleger 21 entsprechend lang ausgelegt sein muß, um die Last hinter dem Hochhaus 20 heben bzw. absenken zu können. Der größere Abstand des Teleskopkranes zum Hochhaus 20 sowie der erforderlich längere Hilfsausleger 21 führen zu einer Tragkraftminderung mit allen daraus sich ergebenden Nachteilen.In order to emphasize the difference from the known arrangement according to the prior art, a customary auxiliary boom 21 was also drawn into the figure. In addition, an obstacle with a high interference edge is shown in the form of a fictitious high-rise building 20 for better understanding. The illustration clearly shows that in the usual arrangement of an auxiliary boom 21 one would not get past the interference edge 22 of the high-rise building 20 . To do this, one would have to set up the telescopic crane very far away from the high-rise building 20 , which is usually not possible due to the space available in narrow urban areas, and the auxiliary boom 21 must be designed to be long enough to raise or lower the load behind the high-rise building 20 to be able to. The greater distance between the telescopic crane and the high-rise building 20 and the longer auxiliary jib 21 required lead to a reduction in the load capacity with all the disadvantages resulting therefrom.
