A patient support apparatus comprises a lower frame (14), a lift mechanism (16), a drive mechanism (38), and an upper frame (12). The lower frame (14) includes a lift drive configured to at least one of expand and contract the lift mechanism (16). The lift mechanism (16) is pivotably coupled with the lower frame (14) to rotate about a rotational axis (R1). A drive mechanism (38) is coupled between the lift mechanism and the lower frame. The drive mechanism (38) is configured to rotate the lift mechanism (16) about the rotational axis (R1). The upper frame (12) is supported on the lift mechanism (16) and responsive to the rotation of the lift mechanism (16) to rotate a patient about the rotational axis (R1).
