Abstract
Method and system for installing the guide rails (1, 2), such as the car guide rails and/or counterweight guide rails, in an elevator shaft (3). The guide rails are installed by assembly in phases starting from the bottom (4) of the elevator shaft by placing one on top of the other guide rail sections (51, 52; 61, 62; 71, 72 . . . ) that are shorter than the whole length of the guide rail and by aligning the guide rail sections perpendicularly by means of the laser beam produced by a direction laser (8). The direction laser (8) is moved upwards along with progressive assembly of the guide rail. As assembly progresses the direction laser (8) is supported in the proximity of the top end of the topmost vertically aligned guide rail section at the time for aligning the next guide rail section to be installed in the vertical direction. These phases are repeated until the entire guide rail is assembled. The system comprises an alignment appliance (12), which can be supported against a guide rail section and fixed to it by means of a permanent magnet (20). In addition the alignment appliance contains an aligning element (13), at which the laser beam produced by the direction laser can be …
