    摘要： In an elevator apparatus, an activating lever that activates an emergency safety gear is disposed on the emergency safety gear. A speed governor mechanism has: a speed governor sheave; a tensioning sheave; and a speed governor rope that is wound onto the speed governor sheave and the tensioning sheave, and that is connected to the activating lever. A resistance applying mechanism is disposed on the car. The resistance applying mechanism applies a resisting force during ascent of the car against movement of the activating lever in a direction that activates the emergency safety gear.

    摘要： An emergency stop device for an elevator car, including: a link configured to be rotated about a rotary shaft installed on a car by movement of a speed governor rope; a rail stopper provided to one end of the link; a roller guide mounted to the car; and an elastic member provided between another end of the link and the car. The elastic member causes a spring reaction force to be reduced to bring the rail stopper into abutment against the roller guide even when the rail stopper is displaced by the link, when the displacement exceeds a preset threshold value due to further displacement by the link along with the movement of the speed governor rope at a time of occurrence of rope breakage.

    摘要： An elevator car includes a car-platform device including a car-platform panel, anti-vibration devices, and a car-platform support frame. The car-platform panel includes a panel main body, a frame structure including a panel frame surrounding an outer peripheral portion of the panel main body, and a panel upper plate and a panel lower plate for individually covering upper surfaces and lower surfaces of the panel main body and the panel frame. The anti-vibration devices receive the frame structure by upper surfaces thereof. The car-platform support frame supports the car-platform panel through an intermediation of the anti-vibration devices. The upper surfaces of the anti-vibration devices are arranged at a height position between an upper surface and a lower surface of the car-platform panel in a vertical direction.

    摘要： A method reduces a sway of an elevator rope supporting an elevator car within an elevator system using an elevator sheave. The method controls, using a movement of the elevator sheave, a tension of the elevator rope according to a control law of the tension of the elevator rope between a first point and a second point. The first point is associated with a contact of the elevator rope with the elevator sheave. The second point is associated with a contact of the elevator rope with the elevator car or a counterweight of the elevator car. The control law is a function of one or combination of a relative position, a relative velocity and a relative acceleration between the first and the second points.

    摘要： In an elevator apparatus, an abnormal acceleration detecting mechanism detects abnormal acceleration of an ascending/descending body due to breakage of a suspending body, and activates a safety device. The abnormal acceleration detecting mechanism includes: an inertia sheave that is rotatable around a sheave shaft independently from an interlocking sheave; a pawl that is connected to the interlocking sheave and the inertia sheave, and that is displaceable between a normal position, and an activating position that displaces a movable shoe to a gripping position; and an elastic body that holds the pawl in the normal position by applying an initial pressure, and that also rotates the inertia sheave together with the interlocking sheave.

    摘要： In a safety gear for an elevator, a pressing spring device applies a resistance force against movement of a normal-wedge guide member in a direction of moving away from a guide rail. A normal-wedge member has a reverse-wedge guide surface becoming more distant from the guide rail as extending upward. A reverse-wedge member is movable with respect to the normal-wedge member along the reverse-wedge guide surface. A vertical-direction spring device applies a resistance force against upward movement of the reverse-wedge member with respect to the normal-wedge member. A spring constant of the vertical-direction spring device is lower than a spring constant of the pressing spring device. The vertical-direction spring device has a region in which a rate of change in force generated along with increase in upward displacement amount of the reverse-wedge member with respect to the normal-wedge member decreases as compared to that in initial displacement.

    摘要： Provided is an elevator device including a main rope configured to support a car and a counterweight, a hoisting machine configured to be driven with the main rope wound therearound, a hoisting-machine controller configured to control the hoisting machine, a car brake controller configured to control a car brake device configured to apply a load to car rails to control raising and lowering of the car, and a vibration detection device configured to detect vibration of the car. When the vibration of the car is detected based on an output signal from the vibration detection device under a running state in which the hoisting-machine controller controls drive of the hoisting machine, the car brake controller controls the car brake device to generate a braking force until the vibration becomes smaller than a set value.
