A combined elevator guiding and braking device ( 30 ) includes movable members ( 34 ) positioned symmetrically about opposite sides of guide rail ( 24 ). Guide members ( 40 ) are supported on the movable members ( 34 ) for following along the guide rail ( 24 ) under normal elevator system operation. When a safety braking function is required, braking members ( 44 ) engage the surfaces on the guide rail ( 24 ) when the movable members ( 34 ) move into a second operating position to achieve the braking function. The inventive arrangement integrates the car guiding and safety braking functions into a single device.
