Definitions

  • the invention relates to an elevator installation.
  • DE 10 2014 220 966 A1 discloses an elevator system in which several cars are operated cyclically in a circulating operation, similar to a paternoster. In contrast to the classic paternoster, each car is driven independently of the other cars and can therefore stop at any stop independently of the other cars. Transfer units are provided in order to transfer the cars from a vertical lane to a horizontal lane in order to finally transfer the cars between different vertical lanes. It is driven by a linear motor.

  • An elevator system with a rack and pinion drive is known from US Pat. No. 1,001,735.9 B2.
  • a hydraulic retarder is provided as a safety brake, which provides a braking force that decelerates the car via the toothing of the rack drive.
