A roll-over transfer for foundry equipment is disclosed in which a "C" shaped frame rolls along a base combining translation and rotation between two end positions. The frame is powered by piston and cylinder actuator connected for a cycloidal operation to provide maximum acceleration and deceleration at the ends of the frame travel. Cables are connected between the frame and base to maintain a predetermined relationship between the translating movement and the rotating movement. Primary and supplemental stops cooperate to positively prevent over-travel in the event of a failure in the drive system. A single clamp and draw actuator is centrally mounted on the frame for clamping and drawing foundry equipment. The machine is flexible in use in that it can be loaded and unloaded from any one of three directions in each of its operated positions.
