BOTTOM HANDLING APPARATUS FOR STEEL CONVERTER VESSELS ABSTRACT OF THE DISCLOSURE A converter vessel bottom handling device having a frame adapted to be supported on a car and which in turn supports a bilaterally movable support table. Four double acting hydraulic lift cylinders are mounted on the support table for vertically moving a lift table upon which is mounted a tilt table adapted to engage and support a converter vessel bottom. A first and second plurality of hydraulic cylinders are coupled to the tilt table for tilting the same relative to the horizontal plane and for rotating said table about a central vertical axis. A set of lugs affixed to the tilt table are provided to be keyed to mating lugs on the vessel bottom for exerting a downward breakaway force one vessel bottom through the use of the lift cylinders when removal of the bottom becomes necessary. In an alternate embodiment, a plurality of jacks are provided on the vessel bottom for exerting a breakaway force between the vessel and vessel bottom assembly.
