Definitions

  • the invention relates to an overhead cable transport installation of the type comprising one or more vehicles which are spaced apart and associated rigidly but disengageably by clamps carried by a carriage associated with a suspension, with two endless cables, carriers and tractors, parallel to each other, placed one beside the other in the horizontal direction, driven by continuous scrolling at the same speed and supported by pylons supported by intermediate pylons.

  • Transport installations with overhead cables are also known in which each tractor carrying cable passes at the level of a pylon on a pendulum which may include support rollers or compression rollers.
  • the pylons are then respectively called support pylons or compression pylons.
  • These pylons include a base, a vertical barrel or extending upwards, a horizontal and transverse bracket relative to the cable tray and two series of rollers for supporting or compressing the cables.
  • connection between the two cables defines a rigid quadrilateral formed by the clamps of the vehicles, which performs a synchronous drive while avoiding any integration of offset and obliquing of the vehicles.
  • the realization of transport installations with two overhead cables with cabins that can be of large capacity requires that the pylons are designed to allow the passage of the cabin carrier trolley, the maintenance of the cables in a constant relative position and finally to marry the generally curved shape of the cable tray in front of a pylon.
  • European patent application 0 093 680 provides for a trapezoidal arrangement of the clamps.
  • the clamps form an equal height above the cable in any plane perpendicular to the line. It turns out in practice that such provisions do not allow a passage of the carriage to the right of the pylons in conditions of sufficient safety and comfort.

  • the comfort rollers 46 roll on the raceways 47, which has the effect of spreading the cables 2a very slightly, of the order of a few millimeters, 2b, rollers 17.
  • This arrangement does not occur in the end stations 9 where the two ramps 29 are provided. In this way, the vehicle 1 is not affected by tremors at the passage of these rollers 17.
  • the release rollers 26 come to bear against the single ramp 29 which is suitably shaped to approach the cable tray 2a, 2b. It follows that the movable jaws 21 pivot around their axis of articulation, against the elastic means 25, which has the effect of opening the clamps 3 which are then in the disengaged state. Simultaneously, the carriage 4 comes to rest on fixed support means such as a U-shaped track, 77, thanks to the support rollers 39. The carriage 4 is guided by the guide rollers 42.
  • the profile of these fixed support means is such that '' they allow disengaging the clamps 3, disengaged, cables 2a, 2b.
  • the routing of the cables 2a, 2b goes away from the bottom and the fixed support means go towards the top of the routing profile of the cables 2a, 2b.
  • the vehicle 1 is braked in its sliding movement by friction bands 48.
  • the same operations are carried out in the opposite direction, that is to say that the fixed support means place the clamps 3 opposite the cables 2a, 2b, the ramp 29 releases the release rollers 26 which allow the clamps 3 to be closed and the friction bands 48 have previously enabled the carriage 4 to be brought gradually to the speed of the cables by acceleration rollers.
