    摘要: A braking system for a hoisted structure includes a guide rail configured to guide the hoisted structure. Also included is a plurality of brake members operatively coupled to the hoisted structure, each of the brake members having a brake surface configured to frictionally engage the guide rail, the brake members moveable between a braking position and a non-braking position. Further included is a plurality of electronic brake member actuation mechanisms operatively coupled to the brake members and configured to actuate the brake members from the non-braking position to the braking position. Yet further included is a load sensing device operatively coupled to the hoisted structure, the load sensing device configured to detect a weight of the hoisted structure, wherein the load sensing device is in operative communication with the electronic brake member actuation mechanisms, wherein the number of actuated mechanisms is dependent on the weight of the hoisted structure.

    摘要: 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.
