As deeply uncool as I am for using AI, I think Chatty P may have nailed it:
“That object is an industrial-sized steam kettle mixer, more specifically the gear assembly and turn wheel for tilting the kettle.
These were common in institutional kitchens like prisons, hospitals, and schools.
Given the state of the item, it looks like the kettle is missing but the support and mechanism remain. This would have been used to prepare soups, stews, or sauces in large quantities.”
