scale device or what?

Another item I picked up that has me baffeled. I might have been
part of a huge hydraulic press assembly. It has rollers underneath
the horizontal section. I think it might have something to do with
indicating deflection as it is not nearly strong enough to take the
300,000 pounds of pressure of the press directly.

below are image locations from several different angles.

If someone knows what it is or has a pressing need for it, let me
know.
