Abstract: A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.

Abstract: A method and a catching device are used to catch a traveling body in an elevator system wherein traveling body is movable along a rail. The catching device includes a first braking element, a second braking element, a first guide element, a second guide element and an actuating element. The first braking element and the second braking element are brought into contact with the rail for braking. A first linear bearing is formed between the first braking element and the first guide element and a second linear bearing is formed between the second braking element and the second guide element. Both guide elements are moved between a rest position and a braking initial position, the actuating element moving the two guide elements from the rest position into the braking initial position.

Abstract: A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.

Abstract: A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element.

The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.

The braking device includes a carrier and a braking element movable between a deactivated configuration, in which a braking surface of the braking element is laterally spaced apart from the guide track, and an activated configuration, in which the braking surface abuts the guide track, in a reversible manner by an activation distance transverse to the guide track. The carrier of the braking device is rigidly coupled to the guide device.

Abstract: An elevator system includes an elevator car and a laser distance measuring device. The elevator car is moved along a travel path that is delimited at the top by an upper boundary and at the bottom by a lower boundary. The laser distance measuring device emits a laser beam and determines a distance to a position at which the laser beam impinges on an object. The laser distance measuring device is mounted on the elevator car such that the laser beam can be directed upward to the upper boundary in a first configuration and can be directed downward to the lower boundary in a second configuration. A current position of the elevator car can thereby be determined in a redundant manner. Furthermore, in a third configuration, lateral distances to boundary markers can be measured to read out information that is codified by the boundary markers.

Abstract: A method for reporting component fault states of a passenger transport system includes the steps: detecting identity information and/or fault state information of a component being examined using a reporting device; automatically transmitting the detected information to an analysis device; automatically selecting a selection of possible causes of the fault from a list based on the identity information and/or the fault information and transmitting corresponding selection information to the reporting device; automatically outputting the selection information from the reporting device and receiving sub-selection information describing a sub-selection selected by a reporter from the selection of possible causes of the fault; and automatically transmitting the sub-selection information to the analysis device. Possible causes of the fault states are reported and collected in a simple and standardized manner.

Abstract: A brake unit for a safety brake of an elevator system has a rolling element on a rolling disk, which rolling element rolls on a stationary rolling track of a braking and guiding rail at least in some sections in the event of an activation of the safety brake. A brake lining of the brake unit interacts with a stationary braking track on the rail as a result of the rolling of the rolling element on the rolling track. At least one marking element on the rolling element produces a start marking and an end marking on the rolling track and/or the braking track when the rolling element rolls on the rolling track. Then the braking distance of the associated elevator car can be determined from the distance between the start marking and the end marking.
