KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. KLASSE 35: Hebezeuge.CLASS 35: Hoists. Um bei Kranen der genannten Art zu verhindern, dafs das Gegengewicht, einmal in Bewegung gesetzt, gleich bis ans Ende seiner geneigten Bahn laufe, und zu bewirken, dafs es sich nur so weit bewege, wie es mit Rücksicht auf die Stabilität des Kranes der Gröfse der gerade zu hebenden Last entspricht, wird hier eine Rolle S von abnehmendem Radius (Spiralrolle) angewendet, welche an einer beliebigen Stelle zwischen dem Lastkettenstrang K und dem beweglichen Gegengewicht G so eingeschaltet wird, dafs das letztere mit wachsender Entfernung vom Kranmittel eine stets zunehmende Spannung des ersteren bedingt.In the case of cranes of the type mentioned, in order to prevent the counterweight, once set in motion, from running straight to the end of its inclined path, and to cause it to move only as far as it would with regard to the stability of the crane's size corresponds to the load to be lifted, a roller S of decreasing radius (spiral roller) is used here, which is switched on at any point between the load chain strand K and the movable counterweight G so that the latter has an ever increasing tension with increasing distance from the crane means of the former conditionally. Paten τ-An spruch:Sponsorship τ claim: An Drehkranen mit selbstthätigem Gegengewicht die Anwendung einer Spiralrolle, welche an einer beliebigen Stelle zwischen dem Lastkettenstrang K und dem beweglichen Gegengewicht G so eingeschaltet wird, dafs die zunehmende Spannung der ersteren eine Vergröfserung der Entfernung des Gegengewichts vom Kranmittel zur Folge hat, und umgekehrt.On slewing cranes with an automatic counterweight the use of a spiral roller, which is switched on at any point between the load chain strand K and the movable counterweight G so that the increasing tension of the former results in an increase in the distance of the counterweight from the crane means, and vice versa.
