600 ton stripper crane
Stripping the moulds from ingots.
Moulds were stripped in sequence with the teeming operations roughly 20 minutes after casting. Special lifting arms on the 4 ton capacity stripper crane would engage lugs on the ingot mould and strip it off the ingot. Ingot teeming and stripping took place in the same bay. When completed, the ingot cars would be hauled by locomotive outside, and then alongside the stripping bay to the soaking pit bay.
You can see the crane operator in the cab of the stripper crane just behind the two lamp reflectors.
But this picture does show the stripping cranes can be rather big. Note that DES makes a lot of other heavy manufacturing equipment and that it is in China.

John Orlando Molds from Valley Mold. Next to Interlake I think.
Bob Green Valley Mold use to pile the ingot mold like that. Trouble was, they piled it too close to the railroad tracks. The ladle would rub up against them as I delivered iron from Interlake Steel.
