Abstract: In an elevator apparatus, a car is suspended by a suspending means. The car is raised and lowered by a driving apparatus by means of the suspending means. The car is braked by a braking apparatus. An abnormal acceleration detecting mechanism operates the braking apparatus to stop the car if acceleration that exceeds a preset set value arises in the car.

Abstract: A speed governor includes: a centrifugal weight that revolves around a predetermined revolving shaft in response to movement of a car; an extensible body to which the centrifugal weight is connected, and that is rotated around the revolving shaft, the extensible body being displaced relative to the revolving shaft in response to a centrifugal force to which the centrifugal weight is subjected due to the revolution; a switching apparatus that extends and retracts the extensible body in response to an elevator operational state; and an operation detecting apparatus that detects whether a state of the extensible body is an extended state in which the extensible body is extended or a retracted state in which the extensible body is retracted. A controlling apparatus determines presence or absence of an abnormality in the speed governor by comparing the elevator operational state and detection results from the operation detecting apparatus.

Abstract: An elevator apparatus has a criterion (overspeed levels) that changes in accordance with an operational condition of a car. The elevator apparatus also has a position information correcting means that corrects an error in value that determines the criterion. In the elevator apparatus, the overspeed levels are determined using continuous information corresponding to car position, while the continuous information is corrected using intermittent information corresponding to actual car position. According to the elevator apparatus, on-the-spot adjustment or long-time maintenance becomes unnecessary, and overspeed detection levels can easily be changed in accordance with the operation conditions of the car.

Abstract: An elevator system and a speed governor detecting first over-speeds of different values set for different moving directions of an elevator car. The speed governor includes a fly weight speed governing mechanism on a sheave on which a speed governing rope is wound and operates in both ascending and descending modes of the elevator car, and a fly ball speed governing mechanism coupled with a horizontal shaft of the sheave via a clutch mechanism. The clutch mechanism transmits the torque of the sheave to a second shaft of the fly ball speed governing mechanism when the sheave rotates in a forward direction, and disengages the transmission of the torque to the second shaft when the sheave rotates in a reverse direction.

Abstract: In a speed governor for an elevator, a clutch mechanism is provided between a governor sheave and a rotary body. An actuator performs switching between transmission and interruption of rotation by the clutch mechanism according to whether or not energization from a DC generator, which generates a current by rotation of the governor sheave, is performed. A rectifier circuit allows the current to flow from the DC generator to the actuator only when a rotating direction of the governor sheave is a predetermined one of a first direction and a second direction.

Abstract: In an emergency stop system for an elevator, a governor sheave that moves in synchronism with the raising and lowering of a car is wound around a governor sheave. The car is mounted with a safety device for braking the car through displacement of the car, which is connected to the governor rope, with respect to the governor rope. A control device outputs an activation signal upon detecting an abnormality in the speed of the car. A rope catching device is provided in the vicinity of the governor sheave. The rope catching device has an electromagnetic actuator that is activated upon input of the activation signal, and a restraining portion for restraining the governor rope upon the activation of the electromagnetic actuator.
