Abstract

Es wird eine Hubseilführung an einem Ausleger (1) beschrieben, insbesondere an dem Ausleger eines Wippkrans, umfassend ein Umlenkrollenpaar (2) und ein darauf aufgelegtes Hubseil (3), wobei das Umlenkrollenpaar (2) eine endseitig an dem Ausleger angebrachte erste Umlenkrolle (4) aufweist, deren Lagerachse (5) im Wesentlichen quer zur Längsachse (6) des Auslegers (1) ausgerichtet ist, sowie eine zweite Umlenkrolle (7), deren Einlaufseite (8) und Ablaufseite (9) des Hubseils (3) mit der Ablaufseite (10) des Hubseils (3) der ersten Umlenkrolle (4) fluchtet.A hoisting cable guide on a jib (1) is described, in particular on the jib of a luffing crane, comprising a deflection roller pair (2) and a hoist rope (3) placed thereon, wherein the deflection roller pair (2) has a first deflection roller (4) attached to the boom at the end ), whose bearing axis (5) is aligned substantially transversely to the longitudinal axis (6) of the cantilever (1), and a second deflection roller (7), the inlet side (8) and discharge side (9) of the hoist rope (3) with the discharge side (10) of the hoisting rope (3) of the first deflection roller (4) is aligned.

Der Erfindung lag die Aufgabe zugrunde, eine Hubseilführung derart weiterzubilden, dass ein Verschleiß der Umlenkrollen, insbesondere deren Seitenwangen, und des Hubseiles verringert wird.The invention had the object of developing a Hubseilführung such that wear of the pulleys, in particular their side walls, and the hoisting rope is reduced.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die zweite Umlenkrolle (7) in der Längsachse (6) des Auslegers (1) gegenüber der Ablaufseite (10) der ersten Umlenkrolle (4) zurückversetzt ist.

Figure imgaf001
The object is achieved in that the second guide roller (7) in the longitudinal axis (6) of the arm (1) opposite the discharge side (10) of the first guide roller (4) is set back.
