ABSTRACT:
An elevator system with a carriage for moving a payload such as personnel or cargo traversely along a vertically lofty silo or other vertically elongated structural environment, the elevator system comprising a finite-length framework along which the vertically movable carriage through a guidable yoke slidably traverses and including at least one upright lugged-rail having laterally projecting horizontal lugs spaced at liberal-increments-intervals therealong. Confined to the carriage and wholly co-movable therewith is a crawling-propulsion assembly which includes a vertically elongated short-length tightenable annular-belt having regularly-spaced openings for removably securely engaging successive lug projections whereby the annular-belt linear leadward frontal-length suspendably supports and crawlably propels the loadable carriage along the framework upright lugged-rail. There is a dual-directional powering means such as, on the carriage, electrical motor and switch for selectively powering the annular belt in both directions for coincident directional movement of the carriage. In certain embodiments, detoothed sprockets are employable to drive the annular-belt.
