A measuring device for measuring an elevator shaft has two cable-like, elongate guide elements that extend in parallel with one another, a measuring platform and a lifting apparatus. Each of the guide elements is fixedly attached to an upper holding point and a lower holding point in the elevator shaft and is tensioned between the upper holding point and the lower holding point. The measuring platform has guide apparatuses that laterally support the measuring platform on the guide elements and guide the measuring platform parallel to the guide elements during a displacement movement in a displacement direction. The measuring platform has a distance measuring apparatus to measure lateral distances to the lateral walls of the elevator shaft. The lifting apparatus moves the measuring platform in the displacement direction.

A measuring tape arrangement is used in an elevator system for determining a position of an elevator car along a travel path. The measuring tape arrangement has a one-piece measuring tape arranged along the travel path, wherein varying location information is stored along the measuring tape, by which information a current position of the car relative to the measuring tape can be determined, and a retaining structure arranged at an upper end of the travel path on which structure the measuring tape is fastened by a fastening device at a fixed position relative to the travel path. A receiving device receiving a measuring tape supply is arranged on the retaining structure, wherein a measuring tape piece of the measuring tape supply can arranged along an extension portion when the travel path is extended upwards by one extension portion.

Methods and devices for recording and processing elevator data of an existing elevator system are described. In some instances, each floor is approached by at least one measuring run, and measurement data representing the floor heights are recorded a measuring device. In addition, a three-dimensional digital-double dataset is generated from component model datasets, which reproduces at least each floor recorded by the measuring run in the recorded sequence and with the determined floor height.

The invention relates to a movable machine room comprising a support platform of a hoisting machine, the support platform comprising one or more releasable mounting mechanisms for releasably mounting the moveable machine room in a hoistway, and a hoisting machine mounted on the support platform; a working platform on top of the support platform, preferably forming a roof of the moveable machine room and/or comprising handrails; and at least one support structure supported by which the working platform rests on the support platform; and wherein each said support structure is selectively actuatable to expand in vertical direction for hoisting the working platform higher above the support platform taking reaction force from the support platform, or to contract in vertical direction for lowering the working platform back towards the support platform. The invention relates to an arrangement and a method implementing the movable machine room.

A rail installation assist device includes at least control circuitry. The control circuitry is configured to acquire displacement information representing displacement of individual rail brackets and a rail joint from a reference position, the rail brackets that fix guide rails in an elevator shaft, the rail joint that joins the guide rails together; estimate, from the displacement information, a change in the displacement information of the rail brackets and the rail joint when the rail brackets are moved to given target positions; calculate an evaluation value for variation in the displacement information before the change and an evaluation value for variation in the displacement information after the change; and set positions of the rail brackets based on a result of comparison between the evaluation values.

A modular sill assembly includes a top layer, a bottom layer, a first fastener, and a second fastener. The top layer includes a first top plate and a second top plate. The first and second top plates define a door channel therebetween. Each of the first and second top plates includes a top surface, a bottom surface, and a blind bore. The blind bore is defined in the bottom surface and extends towards the top surface. The blind bore is threaded. The bottom layer includes a first base plate that defines a through bore. The first fastener extends through the first base plate and is threadably received in the blind bore of the first top plate to secure the first top plate to the first base plate. The second fastener extends through the first base plate and is threadably received in the blind bore of the second top plate to secure the second top plate to the first base plate.

An aligning device is used for aligning a guide rail of an elevator system. The guide rail is held on a shaft wall of an elevator shaft and is displaceable in at least two horizontal directions, oriented crosswise with respect to each other, before a final fixation. The aligning device has a detection device that is configured to detect, in an automated manner, a position deviation of the guide rail from a nominal position, and has a hammer mill that is configured to hammer the guide rail in an automated manner depending on the detected position deviation by exerting pulse-like strikes in one of the horizontal directions toward the nominal position.

A controller controls passenger transport system functionalities and a safety device monitors a safety-relevant function of the system by storing a configured parameter to transfer to a “configured” state. The method includes: the controller receiving a configuration parameter; transmitting the configuration parameter to the safety device; storing a configured parameter in the safety device, based upon the received configuration parameter; transmitting configured data from the safety device to the controller, the configured data encoding an item of graphic information that is shown on a display of the controller, the graphic information uniquely reproducing the configured parameter in a visual, machine-readable manner; reading out the graphic information by an optical read-out sensor of a mobile, processor-controlled data processing device; and comparing the configured parameter reproduced by the read-out graphic information to a target configuration parameter. The controller controlling the functionalities according to whether there is sufficient agreement between the compared parameters.
