ABSTRACT:
To prevent longitudinal displacement of the support or catenary cable and the load carrying, tensioned cable of the suspension system, the spacers or hangers between the catenary or support cable and the carrier cable, as well as the suspension and tension of these cables, are so arranged that, in side view, the two cables touch each other at the midpoint between the pylon to provide for equalization of tension in the cables. At that position, a tension or force equalization plate is clamped to both the support cable as well as to the carrier cable, thereby preventing relative longitudinal displacement of the cables with respect to each other. To provide for smoothing of a roller-suspended load over the cables, the carrier cable is preferably constructed of two parallel cable or rope elements, covered by a bowed or domed trackway which is resiliently supported on the cable elements, the resilient support having greater thickness in the region between spacers than at the zone of suspension, to additionally compensate for sag of the cables upon loading.
