An overhead mandrel manipulator for handling two composite lay-up mandrels. The manipulator includes two opposing brackets (124) having arms (135) that engage the composite lay-up mandrels using lift pins (150). The opposing brackets (124) are rotated approximately 90.degree. each between an open position and a closed position. In the open or closed positions, the brackets are easily attached to the composite lay-up mandrels. When the brackets are moved between the open and closed positions, they rotate the lay-up mandrels approximately 90.degree. . The brackets can be used to apply a compressive force to the two lay-up mandrels when the brackets are in the closed position. The brackets (124) are rotated by a push plate (80) that is driven up and down by a Thomson ball screw (98) connected to a drive motor (30). As the push plate (80) moves up and down, it moves two pairs of drive links (128) upward and downward. The drive links are pivotally connected to the opposing brackets such that movement of the drive links causes the brackets to rotate when the push plate moves up or down.
