摘要:
An elevator includes a drive, a car operatively connected to the drive to traverse along a travel path, at least one guide rail positioned along the travel path to guide the car, a safety brake arranged on the car to exert a braking force on the guide rail, and a safety system. The safety system includes a first safety control unit and a second safety control unit that monitor a safety condition of the elevator. The first safety control unit outputs a stop signal to the drive, in particular to a drive brake and/or to a frequency converter of the drive, and the second safety control unit outputs a trigger signal to the safety brake to bring the elevator into a proper safety condition when an impermissible safety condition of the elevator is detected.
摘要:
A method and control device for monitoring travel movements of an elevator car utilize an electronic control device positioned at the car. Travel movements of the elevator car are travels, speeds or accelerations of the car. At least individual travel movements are subject to redundant detection for the purpose of monitoring. Either the travels or the speeds are redundantly detected and the accelerations singularly detected, or alternatively the accelerations are redundantly detected and the travels or the speeds are singularly detected, or preferably the travels or the speeds and the accelerations are redundantly detected. The electronic control device is preferably arranged at the support rollers of the elevator car.

A monitoring device for an elevator system is used with an assembly device for assembling a shaft retrofit and a method for monitoring an assembly platform. The monitoring device monitors movements of an elevator car and includes a sensor system for detecting a movement variable and at least one analysis device that evaluates the detected movement variable and compares it to a threshold. If the threshold is exceeded, a signal output is triggered to actuate a brake/catching device. The monitoring device selects the threshold from specified thresholds based on a state of the monitoring device. The specified thresholds include at least one normal operation threshold, and the monitoring device indicates a normal state as soon as specified connection elements are connected to it. The monitoring device further contains a checking routine for determining a state of the monitoring device, and selects the threshold from specified thresholds based on the state.

In an elevator installation, an elevator car is movably arranged alongside guide rails and the elevator car is equipped with a brake system with preferably two safety brakes. A movement monitoring system monitors the movement parameters of the elevator car and triggers corresponding warnings or safety measures, if permissible threshold values are exceeded or it provides determined adjusted movement parameters to an elevator control. The movement monitoring system determines a first movement parameter in a time interval and detects an acceleration of the elevator car. The movement monitoring system determines the time interval for determining the adjusted movement parameter as a function of the detected acceleration.

A safety brake for an elevator system having at least one traveling body movable in an elevator shaft along a guide rail and/or a brake rail. The safety brake is suitable for braking and retaining the traveling body on the guide and/or brake rail as required. The safety brake includes a control plate for receiving a brake body and for positioning the brake body relative to the guide and/or brake rail. The brake body is designed in at least two pieces and includes a first brake element and a second brake element. The first brake element is solely for braking and retaining purposes when the traveling body is moving along the guide and/or brake rail in an upward direction, and the second brake element is solely for braking and retaining purposes when the traveling body is moving along the guide and/or the brake rail in a downward direction.

A brake device for an elevator system with a travel body movable in an elevator shaft along a guide and/or brake rail brakes and retains the travel body on the rail as required. The brake device includes a control plate receiving a brake body and for positioning the brake body relative to the rail. The brake body has first and second brake elements pivoted about a common axis. The first brake element is for braking and retaining purposes when the travel body is moving along the rail in an upward direction, and the second brake element is for braking and retaining purposes when the travel body is moving along the rail in a downward direction.

A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g. by a test piece with a barcode maintained in the field of view of the optical sensor.

In an elevator installation an elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. An elevator braking device includes a brake element, a force store, which is constructed to press the brake element against the brake surface, and an actuator, which can act on the brake element. A method of operating the braking device includes the actuator pressing, in a first operational setting, the brake element against the force of the force store away from the brake surface or to hold it at a spacing therefrom, and the actuator freeing, in a second operational setting, the brake element and allowing the force store to press the brake element against the brake surface.
