Abstract
An elevating apparatus comprises an inclined elevator and a load-carrying carriage. The inclined elevator comprises a pair of guide rails, and the carriage is movable along the guide rails by means of a cable. The carriage is movable along the guide rails on rollers provided on rocker arms pivotally mounted on the carriage. The upper portion of each guide rail is angled away from the remaining portion of that guide rail, the upper portions of the guide rails defining a horizontal section of the elevator which constitutes a discharge position for the carriage.
Claims6
A load-carrying elevator having a first linear section inclined at a specified angle and a second linear section downwardly inclined from the higher end of the first section, a pair of spaced tracks located on said sections and forming guide rail extensions from one section to the other, a chassis arranged to travel along said tracks and movable by means of a cable, said chassis comprising spaced side plates, a pair of axles extending between said side plates spaced at intervals along the length of the chassis, rocker arms mounted on each of said axles and pivoted therewith, rollers mounted on said rocker arms engaging the underside of the tracks, and rollers mounted on said rocker arms at either side of the axle arranged to roll on the top surface of the tracks, the load on the carriage being distributed between the axle while the load on each axle is distributed between the rollers engaging the top of the track, the construction being such as to enable a smooth transition of the carriage from a position where both axles are over the first linear section of the elevator to one where one axle is over the first section and the other axle is over the second section of the elevator.
