Abstract: Device (1) for fixing a telpher chair or a telpher car to a cable (2), of the type comprising a part (5,6,8) extending along the cable and forming a travelling surface (12) on which rollers (13) are made to travel, the part having at each of its ends an extension (14,15) comprising an arm (16) which extends laterally relative to the cable and along the latter and which forms a travelling surface (22) or ramp which extends the travelling surface (12) of the part in such a way that the rollers (13) mount or leave by means of tangential contact the travelling surface of the extension (14) at its end or in the vicinity thereof.

Abstract: A safety clamping device for a pull-cable arrangement for use in an aerial cableway comprising a pair of clamping jaws provided with cable-clamping cups disposed internally thereof, a plurality of synthetic-resin strips interposed between the cable-clamping cups and the clamping jaws and a spring storage device disposed in pressure relationship between one of the clamping jaws and a pressure plate whereby a frictional coupling is provided for a pull-cable and a trolley under normal operation, but being effective to drop the synthetic-resin strips and release the pull-cable, to detension the spring device in reaction to increase in friction and/or heat as a protection against development of excessive friction and/or heat.
