Definitions

  • Object of the present invention is a rope for closed-path urban transport systems.
  • ropes for closed-path urban transport systems consist of six outside strands.
  • the main feature of the ropes intended for closed-path urban transport systems is the possibility of realising their continuous-loop joint.
  • the size of the central core must be more than the diameter of the rope strands so as to insert the strand ends at the centre of the rope (originally occupied by the core).
  • the core Since in such portions of the junction the core must be removed, it cannot be assigned the function of supporting loads, and therefore generally it is made of non-metal materials (natural, artificial fibres, extruded materials, etc.).
  • the features of the material used for constructing the core greatly affect the dimensional stability of the rope both as regards the elastic elongation of the rope under tension, and the plastic elongation depending on the load application time.
  • Cores consisting of fibrous materials do not allow the desired stability and moreover, due to their fibrous structure, they can generate dimensional irregularities of the ropes produced with them (irregularities relating to the rope diameter and to the spacing between the strands).
  • the outline of such ropes is such as to generate vibrations during the passage of the rope on the support and deviation rollers, with a consequent reduction of the passengers' comfort and with mechanical problems to the system.
  • purpose of the present invention is that of realising a rope for closed-path urban transport systems which should allow solving the above problems, in particular by reducing vibrations during the rope operation.
  • a further purpose of the present invention is that of realising a rope for closed-path urban transport systems which, although considerably reducing vibrations, should in any case maintain the possibility of extending the junction of the ends of the same rope through splice.
  • Rope 10 for transport systems exhibits a central extruded core 11, around which, during the rope stranding, a shell consisting of a fibrous material is realised.
  • the shell consists of a plurality of small stranded textile ropes 12.
  • rope 10 exhibits a number of strands 13 equal to seven, and the number of small stranded textile ropes 12 is equal to the number of strands 13 of rope 10.
  • the extruded core 11 has a higher compactness with respect to the cores consisting of fibrous materials.
  • a rope for transport systems is collectively indicated with reference numeral 20.
  • rope 20 exhibits a number of strands 13 equal to seven.
  • Rope 20 is provided with a metal core 21 which can optionally be coated with plastic, where such inside coating is indicated with reference numeral 22.
  • Stranding is performed on the hot-formed plasticised metal core 21.
  • a rope for transport systems is collectively indicated with reference numeral 30.
  • rope 30 exhibits seven strands 13 and is provided with a metal core 21, which can be optionally coated with plastic, with the inside coating 22.
  • the described ropes 10, 20 and 30 having seven strands 13 are capable of improving the rope outline for the purpose of reducing vibrations during its operation, maintaining in any case the possibility of performing the junction of its ends through splice.
  • the materials, shapes and sizes of the illustrated details can be of any type according to the requirements, and the same can be replaced with other technically equivalent details.
