The method comprises installing a lowermost first section of guide rail elements, arranging a movable transport apparatus and a movable transport platform in the shaft, connecting a guide rail element provided with a jointing clamp at each end of the guide rail element to the transport apparatus, moving the transport apparatus with the guide rail element upwards, connecting the guide rail element to an upper end of a row of already installed guide rail elements with a plug-in joint provided by jointing clamps, attaching the guide rail element to a wall of the shaft from the transport platform, moving the transport apparatus downwards in order to fetch a new guide rail element.

A support device for supporting a rotary platform of an elevator. The support device includes a first form-fit engagement means at an end of a fixed first guide rail, said end facing the platform, a third form-fit engagement means at an end of a third guide rail fastened to the platform and rotatable with the latter. In an alignment of the platform to a first position, the first and third form-fit engagement means are arranged with respect such that, when the platform deflects, as around an axis arranged in a second direction, the third form-fit engagement means is supported on the at least one first form-fit engagement means.

A locking device for a guide rail is disclosed. The device includes a first edge including a plurality of teeth shaped projections. The first edge compresses and locks a first surface of a covering sheet placed on a base ring. The device also includes a second edge opposing the first edge. The second edge includes a V-shaped groove, wherein the second edge is disposed to hold at least one furrow of the guide rail for interlocking. The first edge and the second edge of the locking device locks air gap between the covering sheet, the guide rail connecting one or more surfaces of the base ring and a vertical pillar coupled to the guide rail.

A structural member of guided fastening connection for an elevator guide rail includes a vertical docking plate, wherein a fixing side plate is welded on two sides of the vertical docking plate symmetrically, a fixing hole is provided on a side of the fixing side plates, an upright plugging plate is welded at two ends of the vertical docking plate symmetrically, the upright plugging plates are docked with a first buckling block on a side, the upright plugging plates are docked with a second buckling block on a side away from the first buckling blocks, the fixing side plates are welded with a lateral arc-shaped plate horizontally on a side away from the vertical docking plate, a turnover strut is provided between the lateral arc-shaped plates horizontally, a middle fixing rod is plugged within a top face of the lateral arc-shaped plates.

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.

An elevator system (2) comprising a hoistway (4), an elevator car (6) and a counterweight (8) arranged to move within the hoistway (4). The system (2) further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway (4) and a guide rail bracket (32) which connects the first and second counterweight guide rails together. An elevator machine (10) is arranged to drive a tension member (14), which couples the elevator car (6) and counterweight together (8), to move the elevator car (6) within the hoistway (4). The system (2) further includes a friction reducing element (36) arranged on the guide rail bracket (32) such that if the tension member (14) moves towards the guide rail bracket (32) during operation of the elevator system (2), the tension member (14) contacts the friction reducing element (36).
