Abstract: In a safety system for an elevator, a safety gear is mounted to a car, the safety gear being electrically operated by an actuator to cause the car to make an emergency stop regardless of whether a running direction of the car is upward or downward. A safety gear controller cuts power supply to a hoisting machine motor and causes the safety gear to make a braking operation upon detection of the slip between the drive sheave and the main rope based on a drive sheave acceleration exceeding a predetermined value.

Abstract translation: 在电梯的安全系统中，将安全装置安装在汽车上，安全钳由致动器电动操作，使轿厢进行紧急停止，而不管轿厢的行驶方向是向上还是向下。 安全钳控制器切断曳引机马达的电源，并根据超过预定值的驱动滑轮加速度，检测到驱动绳轮与主绳索之间的滑差，使安全钳制动制动。

Abstract: A door engagement device for an elevator according to the present invention is configured in such a manner that biasing-force applying/changing means applies a turning preventing force for preventing turning of a lever main body and changes a direction of a biasing force to a direction of an anti-turning preventing force to the lever main body by action of turning guiding means with movement of a car door. Accordingly, an engagement-mechanism driving device can be driven with a reduced space at low cost.

Abstract: In an elevator apparatus, an operation control section controls an operation of a car. Further, a safety monitoring section detects an abnormal state of targets to be monitored during running of the car to stop the running of the car. A safety-monitoring-function inspection section inspects a function of the safety monitoring section. The safety-monitoring-function inspection section causes the safety monitoring section to detect a transition of a state of the targets to be monitored to the abnormal state regardless of an actual state of the targets to be monitored while the car is running under control of the operation control section.

Abstract: An emergency stop system for an elevator includes a state sensor for detecting an operation of a car, a brake device for braking the car, a brake controller for outputting a signal for operating the brake device based on a signal detected by the state sensor, and an uninterruptible power supply device for supplying electric power to the sensor, the brake device, and the controller. The controller has a signal processing/calculating unit for calculating the deceleration of the car based on the signal detected by the sensor, a command value calculating unit for calculating a command value for operating the brake device based on the deceleration of the car calculated by the processing/calculating unit, and a power monitoring device for monitoring state of the uninterruptible power supply device. At least one of the sensor, the processing/calculating unit, and the calculating unit includes independent systems.
