Abstract (en)
[origin: WO2004033353A1] 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.
