Abstract
An assembly 28 for actuating and controlling braking of a car of an elevator system is provided. The assembly includes at least one braking device 20 mounted on the car, supported between the car and a hoistway for movement with the car within the hoistway, and configured to apply a braking force to the car. The assembly also includes at least one corresponding actuator 34 supported by the hoistway and configured to selectively engage the braking device to prevent movement of the car.
Claims13
An assembly for actuating and controlling braking of a car of an elevator system, the assembly comprising:
- at least one braking device mounted on the car, supported between the car and a hoistway for movement with the car within the hoistway, and configured to apply a braking force to the car, the car propelled using a linear motor system;
- and
- a series of actuators at spaced locations and supported by the hoistway, each actuator of the series of actuators configured to selectively engage the braking device to prevent movement of the car, each actuator of the series of actuators configured to engage the braking device in response to an overspeed condition of the car.
An elevator system comprising:
- a hoistway;
- at least one car supported for vertical movement in a lane of the hoistway;
- a linear motor system configured to propel the car;
- and
- an assembly for actuating and controlling braking of the car, the assembly including:
- at least one braking device mounted on the car, supported between the car and the hoistway for movement with the car within the hoistway, and configured to apply a braking force to the car;
- and
- a series of actuators at spaced locations and supported by the hoistway, each actuator of the series of actuators configured to selectively engage the braking device to prevent movement of the car, each actuator of the series of actuators configured to engage the braking device in response to an overspeed condition of the car.
