Description

■ Patentanspruch:■ Claim:

Wippkran für wagerechte Bewegung der Last mittels einer' längs des Auslegers verschiebbaren Führungsrolle, deren Halteseil über eine im Krangerüst liegende Kurvenscheibe geführt und an ihr befestigt ist, dadurch gekennzeichnet, daß die Kurvenscheibe starr im Krangerüst eingebaut ist.Luffing crane for horizontal movement of the load by means of a 'along the boom displaceable guide roller, the tether over a cam in the crane frame is guided and attached to it, characterized in that the cam is rigidly installed in the crane frame.

Die Erfindung bezieht . sich, auf Wippkrane für wagerechte Bewegung der Last und betrifft insbesondere einen derartigen-Wippkran, bei welchem die Last mittels einer längs des Auslegers verschiebbaren Führungsrolle, deren Halteseil über eine im Krangerüst liegende Kurvenscheibe geführt und an ihr befestigt ist, wagerecht bewegt wird.The invention relates. on luffing cranes for horizontal movement of the load and relates in particular to such a luffing crane, in which the load by means of a along the boom displaceable guide roller, the tether over one in the crane frame lying cam is guided and attached to her, is moved horizontally. Gegenüber den bekannten, in dieser Weise ausgebildeten Wippkranen wird erfindungsgemäß der Vorteil erreicht, daß der Seilverschleiß wesentlich herabgesetzt und durch eine entsprechende Formgebung der Kurvenscheibe ein genau wagerechter Lastweg erreicht wird.Compared to the known luffing cranes designed in this way, according to the invention the advantage achieved that the rope wear is significantly reduced and through a corresponding shape of the cam achieves an exactly horizontal load path will. Zu diesem Zwecke wird erfindungsgemäß die Kurvenscheibe starr im Krangerüst eingebaut und kann infolgedessen große Abmessungen sowie eine hiermit verbundene sanfte Krümmung erhalten.For this purpose, according to the invention, the cam disk is installed rigidly in the crane frame and as a result can be given large dimensions and a gentle curvature associated therewith. Auf der Zeichnung" ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt.An exemplary embodiment of the subject matter of the invention is shown schematically in the drawing shown. Das die Last tragende Hubseil α führt über Scheiben b und / nach der Hubtrommel g. Die Scheibeb liängt mit Hilfe eines Halteseiles c an dem Ausleger e des Krans, und zwar läuft das Seil c über eine am oberen Ende des Auslegers vorgesehene Scheibe^ und eine im Krangerüst starr befestigte Kurvenscheibe /. Das freie Ende des Seiles c ist mit einem festen Punkt h des Krangerüstes verbunden. . ■ "The hoisting rope α carrying the load leads over sheaves b and / to the hoisting drum g. The pulley b lengthens with the help of a tether c on the boom e of the crane, and that the rope c runs over a disk provided at the upper end of the boom ^ and a cam disk rigidly fastened in the crane frame /. The free end of the rope c is connected to a fixed point h of the crane frame. . ■ "
