Eisenbahndrehkrane werden meistens so ausgeführt, daß bei höheren Belastungen des Kranhakens die Last durch das Gewicht des Hubwerkes mit der Antriebsmaschine usw.Railway slewing cranes are usually designed in such a way that with higher loads of the Crane hook the load by the weight of the hoist with the drive machine, etc.
sowie durch das meist vorhandene Gegengewicht ausgeglichen ist, so daß die Belastung sämtlicher Achsen des Plattformwagens annähernd gleich ist. Es ist einleuchtend, daß dieses Gleichgewicht bei unbelastetem Kranhaken, also z. B. beim Transport, nicht vorhanden ist, da dann die Kranmaschine und das auf derselben Seite befindliche Gegengewicht —■ auch wenn dieses entsprechend der Größe der Last verschiebbar ist — den Kranwagen einseitig . belasten, so daß die Achsen des einen Endes stärker belastet werden als die des anderen. Wenn auch geringe Unterschiede hierbei belanglos sind, so werden diese doch bei schweren Kranen derartig groß, daß Schwierigkeiten bei der Versendung zu erwarten sind.and is balanced by the counterweight that is usually present, so that the load on all axles of the platform truck is approximately the same. It is evident that this equilibrium when the crane hook is unloaded, so z. B. during transport, is not available, because then the crane machine and the counterweight located on the same side - ■ even if this is movable according to the size of the load - the crane car on one side. load so that the axes of one end are more heavily loaded than those of the other. Even if small differences are irrelevant here, they are so great with heavy cranes that difficulties in shipping are to be expected.
Die Erfindung gibt ein Mittel an, wie diesem Übelstande abzuhelfen ist. Es besteht dies darin, daß das zum Ausgleichen der verschieden großen Lasten angeordnete Gegengewicht, das meist einen recht erheblichen Teil des Gesamtgewichtes des Krans ausmacht, während des Versandes auf diejenige Wagenhälfte gebracht wird, die durch die einseitig angeordnete Kranmaschinerie nicht belastet ist, so daß dadurch beide Hälften annähernd gleiche Belastung erhalten. Erreicht wird dies dadurch, daß man das Gegengewicht von seinem Träger lösbar macht, und es auf die Wagenplattform, die dafür eine besondere Unterlage erhalten kann, aufsetzt und dann den Kran um seine Mittelachse um 180 ° dreht, so daß sein Hubwerk mit Zubehör die andere Wagenhälfte belastet.The invention provides a means by which this disadvantage is to be remedied. It exists this is that the counterweight, which is arranged to compensate for the variously large loads, which usually makes up a considerable part of the total weight of the crane, during the shipping on that Car half is brought, which is not burdened by the crane machinery arranged on one side is, so that both halves receive approximately the same load. Achieved this is done by making the counterweight detachable from its carrier, and it is placed on the wagon platform, which can be given a special base for this and then the crane rotates around its central axis by 180 °, so that its hoist with accessories the other half of the car is charged.
In der Fig. 1 ist beispielsweise ein Kran, bei welchem die Erfindung zur Anwendung gekommen ist, dargestellt. Es ist α die Wagenplattform, die auf den acht Achsen J1 bis O8 ruht und um den Mittelzapfen c drehbar den Kran trägt. Der Kranausleger e ist um seinen unteren Punkt f schwenkbar, so daß die Last bei verschiedenen Ausladungen des Kranhakens gehoben werden kann, und damit er durch Niederlegen in das Normalprofil NP hineinpaßt. Das Hubwerk sowie die dazugehörige Antriebsmaschine usw. befinden sich in dem Führerhaus d, das auf der dem Ausleger entgegengesetzten Seite des Zapfens c liegt. Hinter dem Führerhaus ist das Gegengewicht g an dem Hebel h angeordnet, das in diesem Falle selbsttätig je nach der Größe der am Haken i hängenden Last durch den Zug des Seiles k verstellt wird.In FIG. 1, for example, a crane in which the invention has been applied is shown. It is the car platform α , which rests on the eight axes J 1 to O 8 and carries the crane rotatably about the central pivot c. The crane boom e can be pivoted about its lower point f , so that the load can be lifted at different projections of the crane hook, and so that it fits into the normal profile NP when it is laid down. The hoist and the associated drive machine, etc. are located in the driver's cab d, which is on the side of the pin c opposite the boom. Behind the driver's cab, the counterweight g is arranged on the lever h , which in this case is automatically adjusted by pulling the rope k depending on the size of the load hanging on the hook i.
Soll nun der Kran zum Versand gebracht werden, so werden die Verbindungsschrauben zwischen dem Hebel h und dem Gewicht g gelöst und letzteres wird auf die Plattform a niedergelassen. Hierauf dreht man den Kran um sich selbst, so daß das Führerhaus nunmehr auf der anderen Seite des Wagens, also über den Achsen bb bis bs steht und diese letzteren belastet. Das Gewicht g belastet die Achsen bt bis bi; die Gesamtläst' ist nun-If the crane is now to be shipped, the connecting screws between the lever h and the weight g are loosened and the latter is lowered onto the platform a. The crane is then turned around itself, so that the driver's cab is now on the other side of the car, that is, above the axes b b to b s and loads the latter. The weight g loads the axes b t to b i ; the total burden is now-
