Abstract: In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

Abstract: A method for driving an elevator car brake device, an elevator system for executing the method, and a computer program implementing the method involve the brake device including at least one automatically releasable pressure element effecting a braking action and an electromagnet automatically releasing the pressure element, wherein a respectively required braking torque of the car is ascertained using a model of the elevator system, a direction of car travel, a state of load of the car and a desired car deceleration. A drive signal for driving the electromagnet is generated based on the braking torque and is supplied to the electromagnet, wherein, when the car is braked, an actual car deceleration is ascertained and calibration is performed based on the ascertained actual car deceleration, specifically calibration of the ascertained required braking torque or calibration of the drive signal that is generated based on the ascertained required braking torque.

Abstract: A mounting device for performing an assembly process in an elevator shaft of an elevator system includes a support component and a mechatronic assembly component. The support component moves within the elevator shaft. The assembly component is retained on the support component and carries out a mounting step in an at least partially automatic manner during the assembly process. The support component includes a fastening part that secures the support component and/or the assembly component in a direction extending transversely to the vertical, i.e. for example in a horizontal or lateral direction, within the elevator shaft.

Abstract: A mounting device for performing an assembly job in an elevator shaft of an elevator system has a support component and a mechatronic assembly component. The support component is configured to be moved within the elevator shaft. The assembly component is held at the support component and configured to perform a mounting step as part of the assembly job in at least a partially automatic manner. The assembly component can be an industrial robot. The mounting device allows repetitive mounting jobs, such as drilling holes and driving in screws, etc., to be performed in a partially or fully automated manner. The mounting effort, time, and/or costs thereby can be reduced.

Abstract: In an elevator system, a belt-type suspension device is guided over at least one pulley. A contact surface of the pulley has an anisotropic structure for interacting with the belt-type suspension device. A friction coefficient between the suspension device and the contact surface in a circumferential direction of the pulley is greater than a friction coefficient between the suspension device and the contact surface in an axial direction of the pulley.

Abstract: A device for actuating an electromagnetic elevator brake in an elevator installation includes at least two outlets connected to a coil of the brake, and a control system. Also provided is a switchable dissipation device, which is connected to the two outlets. In a rapid actuation operating mode, the control unit switches the switchable dissipation device such that the magnetic energy stored in the coil dissipates rapidly. Rapid actuation of the elevator brake is thus made possible.
