Definitions

  • the invention relates to an elevator, which is guided in an elevator shaft, with a car, a counterweight assigned to the car and one Drive machine for moving the car.
  • the invention is based on so-called traction sheave lifts or rope lifts.
  • the car In these lifts, the car is suspended on a rope, which is connected to a Traction sheave is guided.
  • the traction sheave is motor-driven and causes that the cabin is moved up or down.
  • Suspension means i.e. the rope
  • the Counterweight is usually heavier than the empty car.
  • the counterweight is usually chosen so that the counterweight is equal to the net weight of the Car and part (mostly half) of the payload and half of the The net weight of the suspension cable is.
  • the one required to drive the car Rope friction between the suspension rope and traction sheave is caused by the Design of the traction sheave and the suspension cable and on the other hand by the Contact pressure of the suspension cable against the traction sheave is determined.
  • the contact pressure of the Carrier rope against the traction sheave depends on the weight of the car, the Counterweight and the suspension cable.
  • Small traction sheave diameters are directly proportional to that torque to be applied and thus to the size of the drive motors.
  • small traction sheaves have the disadvantage that the suspension cable has more is claimed and the rope life is reduced. At that point usually meet traction sheave diameters of at least 40 times the rope diameter used.
  • WO 99/43395 describes that the suspension element comes from an upper rope stop coming twice around a traction sheave and a counter pulley, both on the Floor of the car are attached. Furthermore, the suspension element is fixed to a Roll deflected and ultimately via a loose roll on the counterweight to one guided second upper rope stop. Through this "double wrapping" the Traction sheave the driving ability of the traction sheave is increased.
  • EP 0934440 B1 describes the possibility of using ropes instead of a steel rope to use non-metallic material as a suspension cable.
  • the proposed suspension rope has a plurality of load-bearing strands made of a non-metallic Material are formed, and a jacket that encloses the multiple strands.
  • WO 99/43599 describes the use of drive belts around a drum are wound and by means of which the car moves up or down becomes. With this type of elevator, a counterweight can be dispensed with that the space required for a counterweight can be saved.
  • the invention is based on the object, the operation of a Improve elevator system.

With today's elevator systems, that has Carrier rope on the one hand the function, the suspension of the car and the Ensure counterweight and on the other hand the drive of the machine Transfer car. According to the invention, these two functions of Seils separated and from separate arrangements, namely a car suspension arrangement and a car drive arrangement.

  • both the suspension cable and the drive cable can be assigned to the respective function be adjusted.
  • drive ropes of less Diameter can be used because the carrying function of the carrying rope is taken over.
  • By using drive ropes with less Diameter also makes it possible to add traction sheaves with a smaller diameter use without increasing the wear on the drive cable.
  • lower Traction sheave diameter in turn means a reduction in that Drive motor to be applied torque, so that under certain circumstances on Gears can be dispensed with or less expensive drive motors used can be.
