An exemplary elevator system includes an elevator car situated for movement along at least one guide rail. A braking device is supported for movement with the elevator car. The braking device includes a plurality of magnet members and a plurality of cooperating members. The cooperating members are selectively movable between first and second positions relative to the magnet members. In the first position the elevator car is allowed to move along the guide rail. In the second position the magnet members and the cooperating members cooperate to cause an electromagnetic interaction between the braking device and the guide rail to resist movement of the elevator car along the guide rail. |
