  • the two cars are each coupled via a cable or belt arrangement with a counterweight.
  • at least one cable or belt arrangement has two cable or belt sections, via which one of the two cars is coupled to its counterweight and which run along at least one side of the other car.
  • the second car arranged below the first car is suspended on two carrying cable or carrying belt sections via which the second car is coupled to the second counterweight and which extend vertically upwards from the second car and each along one Side of the first car, so that the first car is positioned between the two Tragseil- or carrying strap sections of the second car.
  • Elevator systems with two cars arranged one above the other in a shaft and movable separately from each other are used in particular in very tall buildings.
  • the rope or belt arrangements have very long lengths in these cases.
  • the cable or belt arrangements can be excited to oscillations, which are caused, for example, by a movement of the building in which the elevator installation is installed. Such building movements can occur due to wind loads or, for example, in the case of an earthquake.
  • the vibrations lead to deflections of the cable or belt assemblies in the horizontal direction.
  • rope or belt sections running laterally along a car will touch the car. This can lead to damage to the car or even the rope or belt sections.
  • the touch of the car generates noise that can disturb the passengers in the car.
  • WO 2008/079145 A1 discloses an elevator system according to the preamble of claim 1.
  • Object of the present invention is to develop an elevator system of the type mentioned in such a way that a deterioration of a car by a rope or belt section due to vibrations occurring can be avoided.
  • the elevator system for limiting cable or belt vibrations has at least one limiting member which is held in a predetermined position in the shaft and associated with a cable or belt section and has at least one limiting element, wherein the at least one limiting element is in dependence on the position of the car, which is coupled via the associated cable or belt portion with the counterweight, between a limiting position and a release position is movable back and forth, wherein the at least one limiting element is positionable in the limit position on the side of the associated cable or belt portion facing the over the cable or belt portion coupled with a counterweight car, and wherein the at least one Limiting element in the release position releases this page.
  • the elevator system has at least one limiting member, with the aid of which any vibrations of the limiting member associated cable or belt section can be limited.
  • the limiting member has at least one limiting element, which is movable between a limiting position and a release position to and fro. It can be provided that a plurality of limiting members are used, wherein each cable or belt section, which runs along one side of a car, at least one limiting member is assigned. In the limit position, the limiting element is positionable on the side of the associated cable or belt section which faces the car coupled to a counterweight via the cable or belt section. In the release position, the at least one limiting element releases this side of the cable or belt section.
  • the at least one limiting element By positioning the at least one limiting element on the side of the cable or belt section which faces the car coupled to a counterweight via the cable or belt section, a deflection of the cable or belt section in the direction of the car can be hindered. In the limiting position, therefore, the at least one limiting element counteracts oscillation of the cable or belt section in the direction of the car.
  • the cars should not be affected by the at least one limiting member when driving past.
  • the car which experiences no coupling with its counterweight over the limiting member associated with cable or belt section, this is not a problem because of Car with all its components in the horizontal direction can take a sufficiently large distance to the limiting member, so that a collision can be avoided even if this car occupies a position at the same height as the limiting member.

  • the at least one limiting element can assume a release position, in which it releases the side of the associated cable or belt section facing the car. In the release position thus a collision with components of the car is excluded, which is coupled via the limiting member associated with the rope or belt section with its counterweight.
  • the positioning of the at least one limiting element in the limiting and the release position is dependent on the position of the car, which is coupled via the limiting member associated with the rope or belt section with its counterweight.
  • the at least one limiting element also takes a distance to the car, which is coupled via the limiting member associated with the rope or belt section with its counterweight. A collision with this car is thus reliably avoided. So that the at least one limiting element adopts its release position in good time, the movement of the limiting element takes place in dependence on the position of the car, which is coupled with its counterweight via the cable or belt section assigned to the limiting element.
  • the second cable or belt arrangement has a suspension cable or suspension belt arrangement on which the second car is suspended and which is guided around a second traction sheave arranged above the two cars and couples the second car to the counterweight and the two suspension cable or carrying belt sections which laterally extends along the first car, wherein each of the support cable or Tragriemenabête is associated with at least one limiting member.

  • the at least one limiting element is automatically movable into its limiting position as soon as the second car exceeds the predetermined minimum distance. This ensures that the limiting element delimits deflections of the associated carrying cable or carrying belt section as soon as the second car, after having passed the limiting element during a journey downwards, exceeds the predetermined minimum distance.

  • each catenary or carrying belt arrangement is compensated by a lower cable or lower belt arrangement.
  • each car is coupled not only via a support cable or strap assembly but also via a Unterseil- or lower belt assembly with its counterweight.
  • the catenary or sling assembly is guided over a traction sheave positioned above the two cars, and the sling or lowerriemen arrangement is guided over a Seilumlenk issued, which is positioned below the two cars.

  • the at least one limiting element is automatically movable into its limiting position as soon as the first car exceeds the predetermined minimum distance. This ensures that the limiting element limits deflections of the associated lower cable or lower belt section as soon as the first car, after having passed the boundary element while driving upwards, exceeds the minimum distance.
  • the first car is at a distance that is greater than the minimum distance below the at least one limiting member associated with the lower or lower belt section via which the first car is coupled to its counterweight, then this lower cable or Lower belt section below the limiting member.
