  • the two holding plates are preferably arranged parallel or essentially parallel to one another.
  • the holding plates of the conveying device expediently assume the load-bearing or load-introducing function of the elevator car.
  • the retaining plates or the two retaining plates are each supported with their two plate ends in the roof area of the cabin or at the upper end of the cabin on two opposite cabin walls of the cabin.
  • a first end of a retaining plate is fixed to a cabin wall of the cabin and that a second opposite end of the retaining plate to a opposite cabin wall of the cabin is fixed.
  • this fixation applies to both retaining plates of the conveyor.
  • the retaining plates effectively prevent deformation of the cabin walls.
  • the forces acting on the elevator car in the course of the up and down movement to be introduced via the cable through the holding plates into the elevator car.
  • the force is expediently first introduced through the cable onto the traction sheave of the conveying device and from there via the retaining plates into the elevator car.
  • the conveying device or continuous winch arranged at the upper end of the elevator car thus assumes the function of the car roof and in particular forms the supporting structure of the roof and furthermore in particular the function of a force introduction component at the upper end of the elevator car for introducing the forces and loads into the elevator car.

  • the two retaining plates and the traction sheave are expediently arranged parallel or essentially parallel to one another.
  • the driving force for conveying or for moving the elevator car up and down is transmitted from a motor or geared motor of the conveying device to the traction sheave of the conveying device via at least two or two positive-locking traction means.
  • the form-fitting traction means are preferably drive chains or toothed belts, toothed chains or the like.
  • the arrangement of at least two or two form-fitting traction devices is within the scope the invention - particularly with regard to a functionally reliable drive and a functionally reliable power transmission - is of particular importance.
