ABSTRACT:
A method and apparatus of spacing detachable passenger carrier units along the length of a moving haul rope in an aerial tramway system is disclosed. The apparatus includes a conveyor system which has a spacing section that is operated at a speed which is reduced by a speed factor determined by the geometry of the passenger carrier units and the geometry and operating parameters of the particular tramway line on which the units are to be spaced. Additionally, the speed of the spacing section is varied in accordance with the number of units which are selected to be spaced along the length of the line as compared to the maximum capacity of the tramway. Input of the selected number of units to a controller programmed with the particular tramway operating parameters and geometry will automatically slave the spacing section so as to discharge units to a launching system at an interval which insures even spacing. Adjustment of errors in spacing is also provided by eddy current drive motors operated immediately in advance of the spacing section at a speed somewhat greater than the speed in the spacing section so as to eliminate gaps between the passenger carrier units and insure that all the units are positioned in touching relation in the spacing section. A conveyor system for controlled, positive advancement of load carrier units along a support rail also is disclosed.
