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： A brake mechanism (10) for an elevator (2) is activated in response to an electronic control signal to prevent movement of an elevator car (16) under predetermined conditions. The brake mechanism is preferably a safety mechanism (10) and does not require a governor sheave, a governor rope, or a tension sheave. The safety mechanism in one disclosed example utilizes a solenoid actuator (22b) and an electric motor (40) and gear box assembly (42) to move safety wedges (18) into engagement with a guide rail (20) to stop the elevator car (16). The safety wedges (18) are held in a non-deployed position during normal elevator operation. If there is a power loss or if elevator car speed exceeds a predetermined threshold, an electronic control signal activates the safety mechanism (10) causing the solenoid to release, which causes the safety wedges (18) move in a direction opposite to that of a safety housing (12) mounted for movement with the elevator car (16). Angled surfaces of the safety housing (12) force the safety wedges (18) into engagement with the guide rail (20). The safety mechanism (10) can be selectively reset from a remote location.

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： 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.
