Abstract
The method comprises measuring the shaft with measuring equipment from a movable transport platform, whereby the form of the shaft and the position of the fastening points for the guide rails is determined based on the information received in the measurement phase, attaching fastening brackets to the guide rail elements and adjusting the fastening brackets based on the measurement results before the installation of the guide rails takes place so that the guide rail elements provided with the fastening brackets can be lifted in the shaft and attached to the fastening points without further adjustment of the fastening brackets.
