摘要： The car is connected to the counterweight with a hoisting member and further with a free fall protection member passing over at least two free fall protection pulleys provided with at least one free fall protection brake, which is controlled by a free fall protection controller. The pre-tensioning of the free fall protection member is at least 50% smaller than the pre-tensioning of the hoisting member. The free fall protection member is formed of at least one cogged belt. Each free fall protection pulley is formed of a cogged pulley mating with the cogged belt.

摘要： A method and an equipment for monitoring the movement of an elevator car detect an acceleration of the elevator car and a travel speed or a travel distance of the elevator car and an integrated travel speed is calculated from the detected acceleration. In that case, the detected travel speed or the travel speed derived from the detected travel distance is used as a start variable of an integration cycle. In addition, the integrated travel speed is compared with at least one predetermined limit speed and a safety measure is triggered if exceeding of the predetermined limit speed is established.

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： An elevator includes at least one elevator car driving along an elevator shaft as well as an elevator control measuring the car position. The elevator further includes a buffer in the shaft pit, whose length is adjustable in response to the car position and car speed. Via this measure, the shaft pit can be reduced in high speed elevator requiring large buffer lengths.

摘要： 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.

摘要： An elevator system 40 includes an over-acceleration and over-speed protection system capable of triggering a machine room brake and a safety trigger when over-speed or over-acceleration conditions are detected. The system includes a speed detector 42 and an acceleration detector 44. Based upon sensed speed and sensed acceleration, the controller 48 calculates a filtered speed of an elevator mass such as an elevator car 16 or counterweight, and compares the filtered speed to the threshold speed to determine whether an over-speed condition has been reached. The controller 48 activates a machine room brake when an over-speed condition exists, and engages an elevator safety 70A, 70B when it determines that the elevator mass is still in an over-speed condition after the machine room brake has been activated.
