摘要： PROBLEM TO BE SOLVED: To stop mischief by judging it in an early stage without error detecting the vibration of the normal traveling, by confirming the value of the load carried by a car when the acceleration of the car exceeds a preset judgment value, judging whether it is the fluctuation by the forced vibration of an passenger, and by alarming it in a case of the forced vibration. SOLUTION: The raising/lowering of a car 1 having passengers therein is actuated by sending and drawing oil in a hydraulic cylinder 2. The speed is detected by a governor 5 but also actuated by the forced vibration by mischief of a passenger. Whether an alarm should be issued or not is judged taking account of the fluctuation in the load without reducing the acceleration judgement value for stopping the mischief. After measuring the load of the car 1 before traveling, it starts the traveling, the acceleration of the car is measured by a rotary encoder 6 and the load is measured by a load-detecting device 9 in traveling. Whether a second judgment value, where the acceleration of the car 1 is lower than the action of the governor 5 and larger than the general traveling, exceeds a first judgment value of the maximum vibration of the general traveling is confirmed and alarmed.

摘要： PROBLEM TO BE SOLVED: To diagnose the abnormality without using an acceleration sensor by estimating the acceleration of a cage from the data of the present position of the cage, frequency-analyzing the estimated acceleration and diagnosing the abnormality from the data of the present position of the cage, the acceleration of the cage and a frequency analysis result and recording its result. SOLUTION: After starting a diagnosis, the cage position signal outputted from a position sensor 2 provided in an elevator mechanism part 1 is inputted. The inputted cage position signal calculates an estimated cage acceleration by an acceleration estimation means 4. The estimated cage acceleration judges whether it is within a prescribed acceleration range and when it is judged that the acceleration is abnormal, an abnormal acceleration part is extracted and frequency-analyzed by a frequency analysis means 5. In the abnormality diagnosis means 6, it is recorded at which position of the cage the abnormality is generated by the cage position signal from the position sensor 2 and by the estimated cage acceleration from the acceleration estimation means 4, it is recorded at which place of the cage acceleration pattern and which extent of the acceleration are generated.

摘要： PROBLEM TO BE SOLVED: To correct sinking and lifting of an elevator car precisely and quickly by using a hydraulic position correcting circuit having a plurality of flow patterns. SOLUTION: Upper control is explained here, but lower control is similar to it. When an elevator car 106 is sunk and it is corrected upward, a pump 1 is operated by an electric motor 2, pressure oil is supplied to an accumulator 4, and energy is accumulated in a hydraulic circuit 15. The flow of pressure oil passing through control valves 14A, 14B for upward correction is controlled, the pressure oil of the hydraulic circuit 15 is supplied to a jack 101, and an elevator main body 106 such as the jack 101 and the elevator car is elevated. Hereby, positional correction can be attained in a short time and highly accurately without performing customary continuous detection and continuous correction of position.
