  • Patent number: 4957047
    Abstract: The revolving cable transport installation, for instance a gondola aerial cableway, has the carriages of the gondolas supported upon two adjacently extending support cables. Between both support cables there is arranged a continuously revolving traction cable. Along the travel path the carriages are coupled with the continuously revolving traction cable by actuatable cable clamps. These cable clamps are connected with the carriages so as to be elevationally movable and they engage the traction cable from below. The traction cable extends at the upper region of the carriages and can support itself within the suspension zones, i.e. between the support masts at the carriages. Thus, the weight of the traction cable does not load the cable clamps and these cable clamps can accommodate themselves to the position of the traction cable independent of the carriages.
