    Patent number: 4092929
    Abstract: Transport installation comprising individual passive vehicles each equipped with a triple grip for coupling the vehicle to a main haulage cable extending along the track or to auxiliary haulage cables for instance acceleration and deceleration cables in a station. One pair of jaws of the grip is open when the two other pairs of jaws are in the coupling position and inversely. A change of cable operation is effected by a single control and the gauge of the grip is maintained small to permit its passing between the guide sheaves of the cables.
