Abstract
A substantially straight rail assembly on which a carriage of a stationary inclined elevator is guided includes two track rails, each having two legs joined by a web having a plurality of holes. Box-shaped frames, each comprising two rails having holes and coupled together with transverse bars, are screwed to the track rails at arbitrary positions in the longitudinal direction of the track rails to couple the track rails together at a predetermined distance from each other. Splice frames connect additional pairs of track rails to the track rails. The box-shaped frames and splice frames are removably mounted to foundations positioned along a gradient surface to mount the rail assembly to the gradient surface at desired angles of inclination. A cable winch or revolving cable drive moves a carriage of the inclined elevator along the track rails.
