Zusammenfassung:The invention provides a method and device of restoring running of lift; when earthquake occurs, the device detects whether the stripe components such as main sling, cable for controlling, speeder cable and cable for balancing wind with the apparatuses in the lifting channel, and causes the lift to automatically recover running when there is no abnormity. An acceleration transducer (11a, 11b) is arranged near the main sling terminal piece (7a, 7b); an acceleration transducer (11c) is arranged at the upper portion of the lift car; an acceleration transducer (11d) is arranged near a speed governor (13); an acceleration transducer (11e) is arranged at the lower portion of the lift car; when any one of the main sling, cable for controlling, cable for balancing and speeder cable winds with the apparatuses in the lifting channel, the abnormal vibration is detected by the acceleration transducer; when these acceleration transducers do not detect the abnormal vibration, the lift automatically recovers running.
