Abstract
A procedure and an apparatus triggers the safety gear of an elevator at a speed lower than the gripping speed. The overspeed governor of the elevator comprises a pulley (3) driven by the safety gear rope and a brake (5) connected to it by knuckle pins (14,14'). The brake is provided with centrifugal weights (16,16'). Eccentric cams (15,15') and a brake disc (6) are also provided for the overspeed governor. At a speed lower than the gripping speed, using a separately controlled solenoid (30) attached to the overspeed governor, the brake (5) is caused to engage the pulley (3) by driving the plunger of the solenoid into the path of rubber rollers (31,32) rotating with the centrifugal weights.
