An elevator apparatus includes a safety circuit section including a plurality of abnormality detection units, a safety control device, failure detection unit, and circuit changeover unit. The safety control device controls electric power supply to a driving device and a brake device in accordance with a content of an abnormality detected by the abnormality detection units. The failure detection unit detects a failure of the safety control device. When the failure of the safety control device is detected, the circuit changeover unit forms a failure-time circuit in which the electric power supply to the driving device and the brake device is interrupted directly by the abnormality detection unit. |
