Abstract
An overhead cable transport installation (e.g., a gondola lift or a chairlift) possesses a transfer rail in an end station on which grips of carriages are detached from the cable. At the exit of this transfer rail a coupling rail section extends parallel to the cable so that the cable is inserted between the jaws of the grip before the closing of the grip for clamping the cable. The coupling rail section comprises a safety device in the form of a sleeve partially surrounding the cable which allows the free passage of the grip when the cable is inserted between the jaws. Conversely, when the cable is outside the jaws, the grip is wedged and held back to prevent the chair from reaching the end of the transfer rail and falling down.
