Abstract: 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.

Abstract: A method for moving an elevator car of an elevator for evacuating passengers from the elevator car in the event of a power failure, wherein a brake blocks a vertical movement of the elevator car, includes the steps of: applying an electrical pulse or a plurality of electrical pulses to the brake of the elevator car to release the brake and unblock the vertical movement of the elevator car, the brake being released for as long as the particular electrical pulse is applied to the brake; determining a covered height which the elevator car has covered during the application of the particular electrical pulse; comparing the determined covered height with a predetermined distance; and terminating the application of the particular electrical pulse to the brake when the determined covered height is equal to or greater than the predetermined distance.

Abstract: A system for controlling access to a restricted-access area in a building has a sliding door system and a controller for the sliding door system. The sliding door system has a door frame and a sliding door which can be moved in the door frame between a closed position and an open position by a drive unit. The door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position. A controller is arranged on the sliding door and is communicatively connected to the drive device. The controller is designed to control a movement of the sliding door between the closed position and an open position. A light projection device is arranged in an interior of the sliding door and is communicatively connected to the controller. The light projection device is designed to project status information specified by the controller for a user requesting access to the restricted-access area as a visible light projection onto a projection surface.

Furthermore, there is also a bracket for attaching the rotational speed sensor and the pinion in a stationary position relative to an axis of rotation of the tapping device, the tapping device having a gearing which can be coupled to the pinion in a rotation-transmitting manner, and the pinion being rotatably mounted in the bracket at two bearing areas.

Abstract: A mounting frame for being displaced and fixed in a shaft has a main frame, a first primary fixing component for supporting the mounting frame on a first shaft wall of the shaft and a secondary fixing component for supporting the mounting frame on a second shaft wall of the shaft opposite the first shaft wall in a fixing direction during fixing of the mounting frame in the shaft. The first primary fixing component and the secondary fixing component are arranged on the main frame. The first primary fixing component and/or the main frame can assume a transport position and a working position. A change of the first primary fixing component and/or the main frame from its working position to its transport position leads to a reduction in an extension of the mounting frame in an extension direction that differs from the fixing direction.

Abstract: A braking apparatus, that brakes and measures load changes in an elevator car, includes a brake, a brake holding arrangement holding the brake on the car, a load measuring device measuring a force acting on a force transmission element and a load measuring device holding arrangement holding the load measuring device on the car. The brake can be displaced relative to the car in a force direction generated by the brake and the load measuring device is held on the car fixed relative to the car in the force direction. The force transmission element is operatively connected to the brake to measure a force acting between the brake and the load measuring device due to a relative displacement of the brake relative to the load measuring device. A connecting piece arrangement connects the load measuring device holding arrangement and the brake holding arrangement in an elastically deformable manner.

Abstract: An assembly device for carrying out assembly steps on a wall and a method for arranging a magazine component on a magazine housing device include a mobile assembly frame, a mechatronic installation component, the magazine housing device, magazine components and a securing device. The magazine housing device houses the magazine components with assembly means housed therein. The securing device, in a securing state, establishes a connection between the magazine components and the assembly frame to secure the magazine components against displacement relative to the assembly frame. The magazine components each have a first coupling element and the securing device has a second coupling element. The first coupling element and the second coupling element are arranged such that the securing device can be detachably coupled to the magazine components by the two coupling elements.

Abstract: A mounting system for performing an installation operation in an elevator shaft of an elevator system has a mounting apparatus that includes a carrier component with a mechatronic installation component, a displacement component, a suspension cable and a deflection roller deflecting the suspension cable between the displacement component and the carrier component. The carrier component is supported against a supporting wall of the elevator shaft by an upper support roller, at least during displacement in the elevator shaft. The suspension cable has, between the deflection roller and the carrier component, a diagonal pull relative to the vertical in the direction of the supporting wall and is guided via the deflection roller such that the diagonal pull can be varied by displacing the deflection roller. The deflection roller is arranged via a holding apparatus on a surface of the supporting wall such that the deflection roller protrudes into the elevator shaft.

Abstract: 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.
