ABSTRACT:
A suspended railway has a track hung via a plurality of hangers from a suspension cable which is supported at intervals at the tops of towers. A beam is provided at each of these towers which bows the track when unloaded downwardly at the tower. A saddle is furthermore provided at the top of each of the towers and has an upwardly open seat receiving and supporting the suspension cable. This seat has a length measured parallel to the length of the beam which is equal to at least one-third of the length of the beam. Furthermore the seat has a central portion with a larger radius of curvature than its flanking end portions. The saddle is carried on rollers for rolling in a horizontal direction parallel to the suspension cables, and can even twist about a vertical axis perpendicular to this horizontal axis.
