  • the invention also relates to a method for adjusting a guide rail in an elevator system.
  • a guide rail is pre-assembled in an elevator shaft and then adjusted.
  • a plumb line is usually used, which is stretched vertically in the elevator shaft and which serves as a reference for the adjustment of the guide rail.
  • a guide rail in an elevator shaft is usually adjusted by measuring the distance between the perpendicular and the guide rail in two spatial directions using a measuring device, comparing the measured distance with reference values and then, if the measured values deviate from the reference values, the position of the guide rail is corrected based on the measured values.
  • This measuring method is very error-prone, in particular because with this measuring method, when the measuring device is placed on the plumb bob, the plumb bob is easily deflected from its original position, which can result in falsified measured values being read.
  • the JP 2018280 A discloses an alternative adjustment method in which a frame is applied to the guide rail, the frame for determining the position of the guide rail with respect to the perpendicular in a first spatial direction having a first viewing window with a first measuring scale and in a second spatial direction a second viewing window with a second Measuring scale has, for a better reading of the measured value, the solder is illuminated.
