摘要： An elevator system 40 includes an electronic system 48 capable of triggering a machine room brake and an electromagnetic safety trigger 46 with low hysteresis and with minimal power requirements that can be released to engage safeties 70A, 70B when car over-speed and/or over-acceleration is detected. The electromagnetic trigger 46 may be reset automatically and may be released to engage the safeties 70A, 70B during the reset procedure. The system includes an over-speed and over-acceleration detection and processing system that is configured to decrease response time and to reduce the occurrence of false triggers caused by conditions unrelated to passenger safety, such as passengers jumping inside the elevator car 16.

摘要： An exemplary elevator braking device comprises a brake housing. A plurality of rollers are supported by the brake housing. The rollers are arranged to be positioned on opposite sides of a guiderail. The rollers are selectively moveable between a first position in which the rollers are spaced apart a first distance and a second position in which the rollers are spaced apart a second, smaller distance so that the rollers engage and roll along opposite sides of the guiderail. At least one biasing member is supported by the brake housing. The biasing member is associated with at least one of the rollers and biases the associated roller toward the other roller in the second position. A plurality of braking surfaces are supported by the brake housing. At least one braking surface is associated with each of the rollers. Each braking surface engages a periphery of the associated roller that faces the side of the guiderail. Friction between the periphery of the associated roller and the braking surface provides a stopping force.

摘要： A safety brake apparatus for a vehicle traveling in an elevator hoistway is provided, comprising a first link (52), a pair of second links (54), a connector rod (56), and an intermediate link (58). The first link is pivotally attached to a first side member of the vehicle. The connecting rod extends through the first and second side members, pivotally mounted within each side member. One of the second links is fixed to the connecting rod on the first side member side of the vehicle and the other second link is fixed to the connecting rod on the second side member side of the vehicle. The intermediate link is pivotally attached to both the first and second links on the first side member side of the counterweight. Each second link is connected to a safety brake. Actuating the first link causes the intermediate link to rotate the second links and therefore the connector rod, and causes the second links to actuate the respective safety brake.

摘要： A rotary actuated overspeed safety device for elevators. The overspeed safety device comprises a pair of pivotally mounted counterweights (12) linked by a pivotally attached coupling rod (16) and a wheel (20) that rollably engages a guide rail. The counterweights are pivotally mounted to the wheel in a parallel plane configuration. Centrifugal force causes the pivotally mounted counterweights to pivot outward toward an actuator as the wheel spins. The overspeed safety device is triggered when the pair of pivotally mounted counterweights engages a housing (22) that is in turn engagably connected to an elevator safety.

摘要： An electromagnetic safety trigger 46 includes a link 72 kinematically connected to a safety 70A, 70B of an elevator system mass, such as an elevator car or counterweight. An electromagnet 76 mounted on a linear actuator 74 is magnetically coupled to the link 72, and a spring 78 is connected between the link 72 and the elevator mass. The electromagnet 76 can be triggered to release the link 72, which allows the spring 78 to move the link 72 to engage the safety 70A, 70B.

摘要： An elevator system 40 includes an over-acceleration and over-speed protection system capable of triggering a machine room brake and a safety trigger when over-speed or over-acceleration conditions are detected. The system includes a speed detector 42 and an acceleration detector 44. Based upon sensed speed and sensed acceleration, the controller 48 calculates a filtered speed of an elevator mass such as an elevator car 16 or counterweight, and compares the filtered speed to the threshold speed to determine whether an over-speed condition has been reached. The controller 48 activates a machine room brake when an over-speed condition exists, and engages an elevator safety 70A, 70B when it determines that the elevator mass is still in an over-speed condition after the machine room brake has been activated.
