An illustrative example embodiment of an elevator includes an elevator car and a drive mechanism connected with the elevator car. The drive mechanism moves with the elevator car in a vertical direction. The drive mechanism includes at least one drive member that is configured to engage a vertical structure near the elevator car, selectively climb along the vertical structure to cause movement of the elevator car, and selectively prevent movement of the elevator car when the drive member remains in a selected position relative to the vertical structure. A biasing mechanism urges the drive member in a direction to engage the vertical structure. The biasing mechanism applies a biasing force based upon a condition of the elevator car. The biasing force changes based upon a change in the condition.
