Description
Die Erfindung bezieht sich auf Krane, insbesondere für Rüstkraftwagen. Bei solchen Fahrzeugen liegt der Kranausleger während der Fahrt zweckmäßig flach über dem Wagenaufbau. Für diese Lage bildet die verhältnismäßig große herabhängende Kranflasche ein Hindernis.The invention relates to cranes, in particular for rescue vehicles. In such vehicles, the crane boom expediently lies flat during the journey above the car body. For this situation the relatively large hanging one forms Crane bottle an obstacle.
Um auch die Kranflasche in der waagerechten Lage des Auslegers in eine entsprechende Stellung zu bringen, sind erfindungsgemäß eine od°rzwei am Ende des Auslegers gelagerte Schwingen vorgesehen, deren freies Ende für die lose Rolle in der oberen Endstellung al4 Anschlag dient und die durch weiteres Anziehen des Seils zusammen mit der losen Rolle in die waagerechte Lage gezogen werden. -Die Aufrichtung erfolgt demnach über den Radius der festen Rolle als Hebelarm des aufrichtenden Moments. Zweckmäßig wird dabei, je nach Art des Antriebes der Winde, eine elektrisch oder mechanisch wirkendeSchalteinrichtung vorgesehen, die den Windenantrieb bei Erreichen der gewünschten Lage der Kranflasche selbsttätig abstellt. Die verhältnismäßig große Winkelbewegung der Kranflasche wird also unmittelbar zur Betätigung der Schaltung herangezogen.In order to also keep the crane block in the horizontal position of the jib To bring a corresponding position, according to the invention, one or two at the end the boom mounted rocker is provided, the free end for the loose role in the upper end position al4 stop is used and the by further tightening the Rope together with the loose pulley into the horizontal position. -The Erecting takes place over the radius of the fixed role as a lever arm of the erecting one Moments. Depending on the type of winch drive, an electric one is expedient or mechanically acting switching device is provided that controls the winch drive Reaching the desired position of the crane block automatically turns off. The proportionate large angular movement of the crane block is thus immediately used to actuate the circuit used.
Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht.The invention is illustrated in the drawing, for example.
Abb. I zeigt die vom Ende des Kranauslegers herabhängende Flasche kurz vor Erreichung ihrer oberen Endstellung; in Abb.2 beginnt die Kranflasche sich aufzurichten, und in Abb.3 ist die Kranflasche in die waagerechte Lage geschwenkt.Fig. I shows the bottle hanging from the end of the crane boom shortly before reaching its upper end position; in Fig.2 the crane block begins and in Fig. 3 the crane block is swiveled into the horizontal position.
In allen drei Abbildungen der Zeichnung ist i das äußere Ende des Kranauslegers, der sich in einer waagerechten Stellung befindet, um vorzugsweise im Falle eines. Rüstkraftwagens während der Fahrt flach über dem Wagenaufbau abgelegt zu werden. Die festen Rollen .2 sind mit ihrer Achse 3 im Kranausleger gelagert. Die Kranflasche 4 mit dem Kranhaken j hängt an dem Zapfen 6 der losen Rolle 7.In all three figures of the drawing, i is the extreme end of the Crane boom, which is in a horizontal position, to preferably in case of a. The equipment vehicle is placed flat over the body of the vehicle while it is in motion to become. The fixed rollers .2 are mounted with their axis 3 in the crane boom. The crane block 4 with the crane hook j hangs on the pin 6 of the loose roller 7.
Auf dem beiderseits über die Lagerschilder des Kranauslegers hinaus verlängerten Achszapfen 3 ist je eine Schwinge 8 gelagert, die in Abb. i senkrecht herabhängen.On both sides over the end shields of the crane boom elongated journal 3 is each mounted a rocker arm 8, which is perpendicular in Fig. i hang down.
In Abb. a ist die Kranflasche durch den Seilzug g so weit hochgezogen, daß der beiderseits über die Lagerschilder der Kranflasche d. verlängerte Achszapfen 6 sich gegen die pfannenartig geformt°n Enden der Schwingen 8 gelegt hat und die Schwingen bereits um einen kleinen Winkel aus ihrer senkrechten Lage gezogen sind. Das aufrichtende Moment wird dabei durch die Zugkraft im Seil und den Radius r der festen Rolle als Hebelarm gebildet.In Fig. A, the crane block has been pulled up by the cable g so far that that on both sides of the end shields of the crane block d. extended stub axles 6 has placed itself against the pan-shaped ° n ends of the rocker 8 and the Swings have already been pulled out of their vertical position by a small angle. The righting moment is determined by the tensile force in the rope and the radius r fixed role formed as a lever arm.
In Abb. 3 ist das Seil g durch die Winde so weit angezogen, daß die Schwingen 8 mit der Kranflasche .I sich in eine annähernd waagerechte Lage aufgerichtet haben. In dieser Lage wird*der Antrieb der Winde durch die Schwingen 8 oder die Kranflasche 4. mittels einer nicht näher dargestellten Schalteinrichtung ausgeschaltet, so daß die Schwingen mit der Kranflasche die gezeichnete Stellung beibehalten. Die Schwingen 8 besitzen eine seitliche Verlängerung io, mit der sie sich auf den Wagenaufbau ii abstützen können.In Fig. 3, the rope g is pulled so far by the winch that the Swing 8 with the crane block .I erect itself in an approximately horizontal position to have. In this position * the winch is driven by the rockers 8 or the Crane block 4. switched off by means of a switching device not shown in detail, so that the swing arms with the crane block maintain the position shown. the Swing arms 8 have a lateral extension io, with which they are attached to the car body ii can support.
