ELEVATOR BRAKE AND SAFETY |
摘要 |
Two hydraulically controlled brakes (32) are attached to an elevator car (10) and each engages a guide rail (18). Each brake (32) is applied by a spring (40). The spring is compressed to release the brake, by actuating hydraulic cylinders (31a) through an electromechanically operated master cylinder (31) that responds to a signal from the motor control (16). An electromechanical release valve (52) is operated by a governor (22), when an overspeed condition exists to quickly release the pressure in the cylinders, applying the brake. |
