  • Patent number: 10640330
    Abstract: A safety device of a lift system may include a car, an evaluation device, and a measuring device. Conditions where departure from a door zone with an open car door or where impermissible accelerations/speeds are reached within the door zone are identifiable by way of the evaluation device and output signals from the measuring device. In such conditions, a control signal may be generated for braking the car. A safety circuit may be connected to the evaluation device and ensure a first safe zone in a shaft head of a lift shaft during an inspection run. The safety circuit may have a safety switch, and the car may include a tripping means for tripping the safety switch. The safety switch and the tripping means have a first relative position upon which the first safe zone is based, and entry of the car into the first safe zone during the inspection run is preventable by tripping the safety switch, which leads to generation of the control signal and braking of the car.

    Abstract: Stall condition in an elevator is potentially dangerous situation if it causes slack to the ropes of the elevator. In such situation a counterweight or elevator car does not move even if the hoisting machine is still operating. This situation may be prevented by stopping the elevator as early as possible after detecting such stall condition. The detection of the stall condition is based on monitoring the torque generated by the hoisting machine of the elevator. When rapid change in the torque is detected a stall condition is suspected. The elevator may be stopped or an alarm may be launched when the stall condition is suspected.

  • Patent number: 8997940
    Abstract: An elevator installation includes a control unit and at least one elevator cage in a building with a plurality of stories, wherein elevator control units are arranged on at least two stories. A travel request is communicated to the control unit, wherein a destination story is defined either by the input into the elevator control unit or by an input into a control unit, which communicates the input to the control unit, and wherein the at least one input travel destination and the at least one input travel request are executed by the control unit by means of a collect operating mode. Energy consumption values of the elevator installation for journeys are determined by the control unit. A journey is undertaken to that destination story or travel request story for which the at least one energy consumption value of the elevator installation is smaller.

  • Publication number: 20150090537
    Abstract: A method and an apparatus for monitoring and supervising the lubricant content of elevator ropes in an elevator, which includes at least a hoisting machine provided with a drive motor, the hoisting machine including at least a traction sheave, around which one or more elevator ropes are fitted side-by-side, which ropes move under the effect of friction along with the rotational movement of the traction sheave and at the same time move the elevator car. The lubricant content is monitored and supervised by the aid of a magnetic measuring device disposed in the immediate proximity of the traction sheave and the elevator ropes by collecting in the measuring device the metal dust detaching in connection with wear of the traction sheave and of the elevator ropes during operation of the elevator and by letting the metal dust switch on an alarm about a lubricant content of the elevator ropes that is too low.

  • Patent number: 8991562
    Abstract: A contacting device for electrically contacting tensile carriers of a suspension in an elevator system includes a housing having a recess in which an exposed segment of the suspension can be received so that the housing at least partially encloses the exposed segment of the suspension. Raised areas and recesses are alternatingly disposed on an inner side of the housing, wherein a raised area and a recess face each other in a state of use. At least one contact element is disposed in a recess of the housing, wherein the at least one raised area can be pressed against a tensile carrier of the suspension, such that the tensile carrier is brought into electrical contact with the contact element.

  • Publication number: 20150083528
    Abstract: A method and a safety arrangement are provided for monitoring the movement of an elevator component, more particularly of an elevator car or of the automatic door of an elevator. In the method, a setup drive of an elevator component is run, and the speed and/or acceleration of the elevator component is measured during the setup drive, a threshold value for the speed and/or acceleration of the elevator component is formed on the basis of the measuring data obtained in the setup drive, the speed and/or acceleration of the elevator component is measured, and if the measured speed and/or acceleration exceeds the aforementioned threshold value, a monitoring signal for bringing the elevator to a safe state is formed.

  • Patent number: 8985280
    Abstract: In a method for limiting loading of an elevator assembly, a limit value for a maximum permitted loading is set for one or more parts of the elevator assembly, and a loading of the one or more parts of the elevator assembly is determined. A movement magnitude value of the elevator car in the movement profile of the elevator car is modified to limit the loading of the one or more parts of the elevator assembly if the loading of the one or more parts of the elevator assembly exceeds the limit value for the maximum permitted loading.

  • Patent number: 8973715
    Abstract: An elevator installation has a guide rail of a predetermined length and a movable body configured to move along the guide rail up and down a hoistway. A proximity sensor is mounted on the movable body to be in a predetermined proximity of the guide rail. The proximity sensor is configured to detect whether or not the proximity sensor is at the predetermined distance to the guide rail. A controller coupled to the proximity sensor acts upon an indication that the proximity sensor is not at the predetermined distance to the guide rail to switch the elevator installation to a secure state.

  • Patent number: 8887873
    Abstract: In an elevator device, a signal diagnosis device includes: a signal input section to which a sensor signal from a sensor is input; a disconnection detecting section for outputting a diagnosis signal for detecting disconnection to the sensor and detecting a state of a signal turned back at the sensor to be input so as to detect whether or not disconnection of the signal from the sensor occurs; a switch for turning ON/OFF an input of the signal to the disconnection detecting section; and a disconnection-detection diagnosis section for operating the switch to diagnose whether or not the disconnection detecting section functions normally. Further, a car is stopped when occurrence of the disconnection is determined by the signal diagnosis device or when an abnormality is detected by the disconnection-detection diagnosis section.

  • Patent number: 8863908
    Abstract: A movement of an elevator cage is detected by an elevator control on the basis of signals of a rotary encoder, coupled with a rotational movement of the drive motor or the drive pulley. Before movement of the cage begins, a movement plot in the form of a trip/speed profile is calculated for travel of the elevator cage from an instantaneous elevator cage position to a destination stopping point position. An anticipated slip between the drive pulley and a support means is included in the calculation of the trip/speed profile, and during the travel of the elevator cage a rotational movement of the drive motor and thus of the drive pulley is controlled by the elevator control in dependence on the calculated trip/speed profile and on signals of the rotary encoder.
