Abstract

Die Erfindung betrifft eine Aufhängung für die Fahrschiene oder dgl. eines Hebezeuges an einem Träger, mit mindestens ein den Träger und die Fahrschiene verbindendes Seil, dessen Enden durch ein Verbindungselement lösbar miteinander verbunden sind. Um zu verhindern, daß bei stoßartiger Belastung, beispielsweise bei einem Abreißen der Fahrschienenbefestigung, die Redundanz-Aufhängung reißt oder die Seile durch die Seilklemmen beschädigt werden, wird vorgeschlagen, daß das Verbindungselement (10) aus zwei baueinheitlich miteinanderverbundenen Keilschlössern (12, 13) besteht, die derartig angeordnet sind, daß das eine Keilschloß (12) um 180 Grad zu dem anderen Keilschloß (13) verdreht ist. Dementsprechend sind die Wirkrichtungen der die Seilenden (9a, 9b) klemmenden Keile (18, 19) entgegengesetzt. Die von entgegengesetzten Richtungen einlaufenden Seilenden (9a, 9b) sind nach Umlenkung um die Keile (18, 19) der Keilschlösser (12, 13) entgegen ihrer Einlaufrichtung zurückführbar und von den Keilen (18, 19) mindestens unter Last klemmbar.

Figure 00000001
The invention relates to a suspension for the running rail or the like. A hoist on a carrier, with at least one rope connecting the carrier and the running rail, the ends of which are releasably connected to one another by a connecting element. In order to prevent the redundancy suspension from tearing or the cables being damaged by the cable clamps in the event of a sudden load, for example when the rail fastening is torn off, it is proposed that the connecting element (10) consist of two wedge locks (12, 13) which are connected to one another in structural terms which are arranged such that the one wedge lock (12) is rotated by 180 degrees to the other wedge lock (13). The directions of action of the wedges (18, 19) clamping the rope ends (9a, 9b) are accordingly opposite. The cable ends (9a, 9b) coming in from opposite directions can be returned after deflection around the wedges (18, 19) of the wedge locks (12, 13) against their direction of entry and can be clamped by the wedges (18, 19) at least under load.
