Abstract
A method and arrangement for aligning elevator guide rails includes a measuring step and a separate aligning step. The alignment of guide rails supported with adjustable fastening members in the shaft is measured in several measurement points along the height of the guide rail line based on at least one reference line provided in the vicinity of the guide rails. The measurement results are stored into a memory. The guide rails are aligned based on the measurement results stored in the memory. The aligning step is carried out after the measurement results of all measurement points have been stored in the memory.
