Abstract: 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 drive members that are configured to engage surfaces associated with walls near opposite sides of the elevator car, climb along the surfaces to selectively cause movement of the elevator car, and selectively prevent movement of the elevator car when the drive members remain in a selected position relative to the wall.
