Abstract: An arrangement for aligning guide rails of an elevator, comprising a carrier moving upwards and downwards in an elevator shaft along guide rails, at least one plumb line being provided in the vicinity of each guide rail. A laser scanner is attached fixedly or movably to the carrier or to the guide rail or to an apparatus, which is supported on walls of the elevator shaft and/or on the carrier. The horizontal position of the guide rail in relation to the plumb line is determined with the laser scanner.

Abstract: An arrangement for aligning guide rails includes an installation platform arranged to be movable in the first direction upwards and downwards in an elevator shaft, said installation platform being provided with an apparatus for aligning guide rails. At least two laser transmitters are arranged at predetermined positions in the shaft below the installation platform, each of said at least two laser transmitters transmitting an upwards directed laser beam that forms a plumb line in the elevator shaft. At least two first position sensitive detectors are attached to the installation platform and/or to the apparatus for aligning guide rails and/or to the guide rails, each of said at least two first position sensitive detectors receiving a respective laser beam, whereby the position of the guide rails in relation to the shaft can be determined indirectly or directly.

Abstract: An arrangement includes an installation platform arranged to be movable upwards and downwards in a first direction in the elevator shaft, and two laser transmitters arranged at a bottom of the elevator shaft. Each of the two laser transmitters produce a vertical upwards directed laser plane in the elevator shaft, the laser planes being perpendicular to each other. At least four primary light sensitive detectors are attached to the installation platform so that they are visible to the laser transmitters, each of the primary light sensitive detectors being positioned on a respective side of a rectangle. The position of the installation platform in relation to the elevator shaft can be measured from the hitting points of the laser planes on the primary light sensitive detectors.

Abstract: The invention relates to an elevator guide rail straightness measuring system, for measuring the straightness of elevator guide rails, which measuring system comprises at least one plumb line mounted vertically in the runway adjacent to the guide rail and at least one sensor arrangement to be mounted on a carrier to travel vertically along the guide rail, which sensor arrangement comprises a frame, at least one guide shoe connected to the frame for sliding/rolling along a guide surface of the guide rail, a bias means for placing and biasing the frame against the guide surface, and at least one sensor means for sensing the position of the plumb line with respect to the frame, such elevator system allows easy and exact measurement of the guide rail straightness. The invention also relates to an elevator having such a system.

Abstract: The arrangement comprises an installation platform movable upwards and downwards in the elevator shaft, at least one light source arranged at a predetermined position in the elevator shaft below the installation platform and producing a vertically upwards directed collimated light beam, at least one primary digital imaging device positioned on the installation platform and being arranged to take electronic images of the light beam hitting the photosensitive sensor of the at least one primary digital imaging device or of a pattern created by the light beam on a reflective or transparent screen positioned at a distance in front of the photosensitive sensor of the at least one primary digital imaging device, whereby the horizontal position of the installation platform in relation to the elevator shaft can be measured from the electronic images taken by the at least one primary digital imaging device.

Abstract: The apparatus includes a stationary part being attachable to an elevator guide rail element at a predetermined height above a joint between two consecutive end-on-end mounted elevator guide rail elements. An elongated measuring frame having an upper end and a lower end is supported from the upper end with an articulated joint at the stationary part. A number of inductive sensors are positioned on the measuring frame, whereby at least a part of the inductive sensors are directed in a first direction being the direction between the guide rails towards a tip of the guide rail elements, said part being further divided into two sub parts so that a first sub part of the inductive sensors is directed towards the upper elevator guide rail element and the rest are directed towards the lower elevator guide rail element. The apparatus further includes a connection board for the inductive sensors, a visualization device, electronics, and a power source.
