    摘要： An escalator device includes a plurality of steps, wherein both sides of each step are provided with mounting portions and step wheels rotatably mounted to the mounting portions; step wheel guide rails fixedly arranged on both sides of the escalator device for guiding the step wheels of each step, during the operation of the escalator device, the step wheels of each step move along the step wheel guide rails on both sides respectively; and anti-detachment guide rails arranged on both sides of the escalator device, during the movement of the step wheels of each step along the step wheel guide rails on both sides respectively, the anti-detachment guide rails are located above and spaced apart from anti-detachment portions of each step, a piezoelectric sensor is provided on the surface of the anti-detachment guide rail facing the anti-detachment portion.

    摘要： A handrail tension monitoring device for a passenger transport system designed as a moving walkway or escalator can include a distance sensor and a signal processing unit. Measurement signals detected by the distance sensor can be processed and evaluated in the signal processing unit. A vibration frequency of a scanned handrail of the passenger transport system can be determined from the signal curve of the measurement signals and the vibration frequency can be compared with a lower threshold value or upper threshold value. An alarm signal can be generated if the lower threshold value is not reached and a warning signal can be generated if the upper threshold value is exceeded.

    摘要： The application relates to passenger transport systems and related methods. The passenger transport system has multiple step units, a comb plate, a monitoring device, and a marking device. The step units are to be moved one behind the other continuously along a predefined movement path during normal operation. The comb plate is arranged at a fixed position relative to the predefined movement path. The monitoring device is configured to monitor an actual position of a currently monitored step unit relative to the predefined movement path and to detect a deviation of the actual position from the predefined movement path by more than an allowable tolerance value and activate the marking device in response thereto. Upon being activated, the marking device is configured to mark the currently monitored step unit and/or a step unit spatially correlating to the currently monitored step unit.
