Description
Für fahrbare, insbesondere straßenfahrbare Hebezeuge wird häufig die Forderung gestellt, den Ausleger in Fahrstellung so unterzubringen, daß er nicht oder nur unwesentlich über das Fahrgestell hinausragt. Die Erfindung zeigt einen Weg, dieser Forderung auf einfache Weise zu genügen.For mobile, in particular road-driven hoists, the requirement is often asked to accommodate the boom in the driving position so that it is not or only insignificantly protrudes beyond the chassis. The invention shows one way of meeting this requirement in a simple way to suffice.
Das Wesen der Erfindung besteht darin, daß der die Auslegerspitzenrollen für HaItseil und Hubseil tragende Block längs des Auslegers beweglich gelagert und auf eine Absetzstelle verschiebbar ist, so daß der Ausleger ohne Spitzenrollen abgenommen werden kann. Vorzugsweise wird der Ausleger ,auf einen Zapfen aufsteckbar ausgebildet, der bei der Fahrstellung des Kranes als Träger des Rollenschlittens oder Rollenkastens dient.The essence of the invention is that the jib tip rollers for HaItseil and hoist rope-carrying block is movably mounted along the boom and is displaceable to a set-down point, so that the boom can be removed without top rollers. Preferably the boom is on a pin designed to be plugged on, which acts as a carrier when the crane is in the driving position the roller carriage or roller box is used.
Das Fußende des Auslegers wird also alsThe foot end of the boom is therefore called
Absetzstelle für den Rollenblock benutzt, so daß dieser immer gegenüber dem * Ausleger ausgerichtet bleibt und nur verschoben zu werden braucht. Der abgenommene Ausleger ist vom Gewicht des Rollenblocks vollständig entlastet und daher verhältnismäßig leicht zu handhaben. Legt man ihn während der Beförderung des Kranes auf den nicht drehbaren Unterwagen ab, der zu diesem Zweck mit Haltevorrichtungen versehen ist, so erzielt man den Vorteil, daß der drehbare Oberwagen samt Windwerk und sonstigen Triebwerken ohne Rücksicht auf die Abnehmbarkeit des Auslegers in üblicher Weise ausgeführt werden kann.Set-down point used for the roller block, so that it is always opposite the * boom remains aligned and only needs to be moved. The removed boom is completely relieved of the weight of the roller block and is therefore proportionate easy to use. If you put it on the not while the crane is being transported rotatable undercarriage, which is provided with holding devices for this purpose, so one achieves the advantage that the rotatable superstructure including winch and other Engines in the usual way without regard to the detachability of the boom can be executed.
In der Zeichnung ist ein Ausführungsbeispiel für die Erfindung dargestellt. Abb. 1 zeigt den Kran in Arbeitsstellung, Abb. 2 den Kran in Fahrstellung. Die Abb. 3 und 4 zeigen Draufsicht und Rückansicht, während Abb. 5 den Rollenkasten wiedergibt.An exemplary embodiment of the invention is shown in the drawing. Fig. 1 shows the crane in working position, Fig. 2 shows the crane in driving position. Figs. 3 and 4 show top and rear views, while Fig. 5 shows the roller box.
Auf dem Unterwagen 1 ist drehbar der Oberwagen 2 gelagert, der bei 3 die waagerechte Drehachse für den Ausleger 4 trägt.On the undercarriage 1, the uppercarriage 2 is rotatably mounted, the horizontal one at 3 Axis of rotation for the boom 4 carries.
