  • Patent number: 6389980
    Abstract: A station for boarding a chairlift for continuously moving ropeway transport. The chairlift includes several seats, either fixed or detachably coupled at regular intervals. Each seat is taken in turn by successive ramps, an arrival, a turnaround and a departure ramp, the arrival and departure ramps being parallel. The turnaround ramp includes two turnings, upstream and downstream, separated by a rectilinear transfer ramp. A boarding site is located at an exit of the downstream turning. An angle &agr; between the arrival and transfer ramps, corresponding to the upstream turning is acute. An angle between the transfer and departure ramps, corresponding to the downstream turning is obtuse. The drive elements cause each seat to pivot on itself at the transfer ramp.
