Abstract

Lastbegrenzungsvorrichtung zur Anordnung im Kraftfluss von Hebezeugen, insbesondere von Kränen, zur Vermeidung von Überbeanspruchungen des Hebezeugs durch oberhalb einer vorgegebenen Nennlast liegende Überlasten, mit einem Hydraulikelement (1) mit einem in einem Zylinder (2) verschiebbar angeordneten Kolben (4), wobei der Kolben (4) bei Lasten bis zur Nennlast über ein im Zylinder (2) angeordnetes Fluid gegenüber dem Zylinder (2) lagegesichert ist, und wobei das Hydraulikelement (1) ein Überlastventil (9) aufweist, welches bei Überlast einen Strömungskanal für das Fluid freigibt und dadurch eine Verschiebung des Kolbens (4) im Zylinder (2) ermöglicht, sowie Hebezeug mit einer solchen Lastbegrenzungsvorrichtung sowie Verwendung eines Hydraulikelements (1) als Lastbegrenzungsvorrichtung.
