Definitions

  • the invention relates to a method for operating an elevator installation and to such an elevator installation.
  • the elevator doors of the elevator system are actuated by a door drive via a travel curve.

The travel curve contains information on the duration and speed of opening and closing the elevator doors as well as on the kinetic energy of the elevator doors during these operations. Depending on the prevailing wind conditions in the shaft, the elevator doors can be closed with more or less force and time, which impairs the transport performance. __
