<p>Disclosed are a plurality of improvements in pusher ram construction for use in coke ovens and the like. These improvements include: 1) two separate "heat spring" arrangements for absorbing both heat and mechanically induced stress in the web portion of a pusher ram, while maintaining desired rigidity; 2) five different constructions for relieving stress developed in welds in pusher ram beam members and/or welded connections between the web portion of a pusher ram and adjacent beam members; 3) two unique girder assembly arrangements to facilitate component replacement; 4) an improved girder web construction for accommodating decarbonizer piping or the like; 5) several useful advancements in ram head design and construction; 6) special heat shield applications for pusher rams; and 7) improvements in ram girder "bull nose" construction.</p> |
