Abstract

[PROBLEMS] To provide a safety system of an elevator in which the position of a cage in the vertical direction can be detected conveniently with high reliability, and landing error between the cage and a floor can be detected at a plurality of levels. [MEANS FOR SOLVING PROBLEMS] The safety system of an elevator comprises a plurality of detection bodies (17, 18, 23, 24) arranged on the same vertical line in an elevator shaft, and a plurality of detectors (13, 14) provided in the cage (1) to oppose each pair of detection bodies, wherein the position of the cage in the vertical direction, e.g. landing error between the cage and a floor, is detected at a plurality of levels based on a plurality of output signals from the detectors. Furthermore, validity of opposing detection by detection bodies and detectors is judged based on the cage position information from second cage position detecting means (8, 9) for detecting the position of the cage in the vertical direction equivalently or measurement information on an elapsed time or a moving distance from opposing detection of a detection body by a detector to opposing detection of the next detection body.
