Abstract (en)
[origin: WO2008011895A1] The invention relates to a lift comprising a lift cage which is guided in a shaft along guiding rails, said lift comprising an electronic system, inter alia, for controlling or regulating the running of the lift, and an emergency braking device for preventing the lift cage from overspeed. The emergency braking device comprises a braking device and a detector device (11) which emits a signal for actuating the braking device in the event of overspeed of the lift cage. The detector device (9, 11) comprises at least two wheels which are arranged on a guiding rail (2) and each drive a detector (11) emitting a signal which is a measure for the rotational angle or rotational speed. The electronic system is embodied in such a way that it functionally uses the detector signals, in that at least one detector signal is examined during the operation of the lift within the authorised speed range in order to determine at least one path, speed and/or acceleration variable influencing the subsequent operation of the lift installation, and in that the electronic system actuates the braking device as soon as at least one of the detectors (11) announces an overspeed of the lift cage outside the authorised speed range, by means of the detector signal thereof.
