    摘要： A control cable guide device for an elevator, which is to be mounted to a control cable suspended between a middle portion of a hoistway and a lower portion of a car, the control cable having a curved portion formed at a lower end position of the control cable, the control cable guide device including an arm to be suspended on the control cable at a position below the car in a pivotable manner. The arm is configured to be pushed upward by the curved portion when the car is caused to travel to a lowermost position within a normal traveling range, to thereby shift to a cable receiving position for receiving the control cable while being partially projected from the car in a horizontal direction.

    摘要： A break detection device includes an extraction unit (22), an extraction unit (23), a detection unit (24), and a determination unit (26). The extraction unit (22) extracts, from an output signal from a sensor, a vibration component in a specific frequency band. The extraction unit (23) attenuates, from the vibration component extracted by the extraction unit (22), a steady vibration component and a progressively increasing vibration component to extract a determination signal. The detection unit (24) detects, on the basis of the determination signal, occurrence of an abnormal variation in the output signal from the sensor. The determination unit (26) determines whether or not a rope has a broken portion.

    摘要： A method reduces a sway of an elevator rope supporting an elevator car by controlling a tension of the elevator rope. The tension is controlled using a movement of the elevator sheave according to a control law of the tension of the elevator rope between two points. The first point is associated with a contact of the elevator rope with the elevator sheave. The second point is associated with a contact of the elevator rope with the elevator car or a counterweight of the elevator car. The control law is a function of one or combination of a relative position, a relative velocity and a relative acceleration between the first and the second points.

    摘要： A method reduces a sway of an elevator rope supporting an elevator car within an elevator system using an elevator sheave. The method controls, using a movement of the elevator sheave, a tension of the elevator rope according to a control law of the tension of the elevator rope between a first point and a second point. The first point is associated with a contact of the elevator rope with the elevator sheave. The second point is associated with a contact of the elevator rope with the elevator car or a counterweight of the elevator car. The control law is a function of one or combination of a relative position, a relative velocity and a relative acceleration between the first and the second points.
