Abstract (en)
The invention relates to an elevator and a method for replacing guide rail guiding devices of an elevator. The elevator shaft of the elevator has guide rails on opposite sides of the elevator shaft. The guide rails are engaged with guide rail guiding devices mounted on both sides of the elevator car that limit the transverse movement of the elevator car between the guide rails. The guide rail guiding devices comprise two coplanar wheels having a wheel portion and a flange portion. The wheel portions rollably engage both flanks of a guide rail web from both sides of the web. The flank portions on guide rail guiding devices on both sides of the elevator car serve to restrict the transverse movement of the elevator car in the direction between the guide rails.
