  • Car and counterweight are moved along respective guides in a hoistway.
  • the car is typically formed with guide rollers which cooperate with the car guide (guide rails).
  • a hanging cable is connected to the car.
  • the car is e.g. supplied with electrical energy.
  • data can be exchanged between the car and an external computer or control unit via the suspension cable.
  • the hanging cable is typically fastened on one side or the floor of the car on the one hand and on or in the elevator shaft on the other hand.
  • a side wall of the car which is preferred for certain embodiments of an elevator system
  • the car To ensure good handling and a high level of ride comfort, the car must be as precisely balanced as possible. Therefore, for compensation this over the length of the shaft variable load due to the suspension cable balancing mass be provided on the car. As a result, for example, a torque or torque, which exerts the suspension cable due to its weight on the guide rollers of the car, can be compensated, whereby the load on the guide rollers can be reduced.
  • the elevator installation according to the invention has at least one car which can be moved in an elevator shaft, wherein a suspension cable is connected to the car, which has a first car-side end and second shaft-side end.
  • the weight of the suspension cable is introduced at least partially above the car into a supporting means engaging the car or into a compensating means acting on the car.
  • the elevator installation according to the invention particularly preferably has two or more, for example three or four, elevator cars which can be moved in a common elevator shaft.
  • suspension cables of an upper car can be easily guided past a lower car.
  • the weight of the suspension cable is introduced into a suspension, in particular suspension ropes or strap of the car.
  • a support means attacks in particular centrally on a car or its catch frame, so that by introducing the weight of the suspension cable in this suspension means a reduced torque load of the car can be ensured by the suspension cable.
  • a support structure is provided, which is connected above the car with the support means and which carries the hanging cable, which thus initiates the weight of the suspension cable in the support means.
  • the support structure is connected to the support means at at least one location and carries the hanging cable at at least one further location.
  • linkage or Tragioloecke conceivable as a support structure in this context.
  • this support structure is a support triangle, which is connected to at least one corner, in particular two corners, with the support means, and at at least one other corner carries or receives the hanging cable weight.
  • Such support triangles can be dimensioned according to the specific loads in a simple manner.

  • the connecting element may in particular be designed as a connecting cable or connecting rod.
  • suspension cable suspension on a rotatably mounted on the car lever, said lever is connected via a connecting element, in particular a rod or a rope, with the support structure. Even with this construction, a vertical decoupling of the suspension cable from the car can be realized.
  • the invention can be used in particular in the case of suspension elements, which are guided by the car via at least one deflection roller to a counterweight. It can also be used with suspension elements, which are deflected from a counterweight (first end of the suspension element) to the car, and from this back to the counterweight (wide end of the suspension element), wherein the suspension element is deflected on deflecting rollers provided on the car.
  • the support means extends to form a loop, wherein the hanging cable can be connected via a corresponding suspension with the loop, so that its weight can be introduced into this loop or the support means.
  • the weight of the suspension cable is introduced into a compensating means, for example designed as a sub-cable, of the car.

They usually run between the bottom of the car and the bottom of the counterweight, and are deflected via at least one provided in the pit pit role.
  • one of these rollers is formed in the context of a lower cable tensioning device.
  • the hanging cable may be attached to a suspension which is designed to be movable in a vertically movable carriage on one side of the car, wherein the suspension advantageously via a connecting mechanism, in particular a connecting element, e.g. a connecting rod or a connecting cable, is connected to the sub-cable or possibly provided on this support structure.
