Abstract
A method for installing guide rails of an elevator in a hoistway includes installing one or more guide rails to form a vertical guide rail line; positioning an elevator car at a first position in the hoistway; placing a plurality of guide rails to stand in an upright position on the elevator car such that each of the guide rails rests on the floor structure of the elevator car; supporting the upper half of each of the guide rails laterally on the elevator car for blocking its lateral movement relative to the elevator car; hoisting the elevator car in the hoistway upwards to a second position, along the guide rail line; and installing a guide rail belonging to said plurality into the elevator hoistway on top of the guide rail line for extending the guide rail line vertically, thereby making the guide rail being installed to form the uppermost section of the guide rail line. An installation arrangement of guide rails is provided for implementing the method.
