<p>An aerial transportation system including two generally parallel endless aerial carrier and traction cables is disclosed in which apparatus is respectively associated with each of the cables for separately supporting each cable. The supporting apparatus associated with each cable each comprise at least one basic balance beam, at least one roller rotatably mounted at one end of the balance beam for engaging its associated cable and at least one support balance beam with the basic balance beam being pivotally mounted at one end on the support balance beam for pivotal movement about a pivot axis extending at right angles to the cables. A support structure is provided for the balance beams with the support balance beam being pivotally mounted on the support structure. The basic balance beams, rollers and support balance beam associated with each cable are arranged on their respective support structures in facing relation to each other so that the basic balance beams on the respective support structures, and located in facing relation to each other, are mechanically independent of each other. The amplitude of pivoting of the basic balance beams about their respective pivot axis are limited between two predetermined extreme positions.</p> |
