  • Patent number: 4050385
    Abstract: There is disclosed a high capacity passenger transport apparatus which may be employed as a ski lift including a high speed main cable ascending up a ski run and driven at high speeds. A pair of first and second shuttle tracks lead from the downhill run of such cable at the bottom station and separate to pass through respective first and second loading areas and then merge back together at the uphill run of the high speed cable. Chair trucks are carried on the main cable and include releasable grippers gripping such cables and are intercepted at the end of their downhill travel by escort cars which decelerate such trucks and escort them past a selector switch to direct alternate ones thereof onto the respective first and second shuttle tracks and then to a stopped position at the loading area so skiers can be loaded thereonto.
