Mechanical contraption

I took this picture June 19, 2018 and can't remember where I took it and what it actually is. to me it looks like some sort of a shuffle which might fold up.

Please let me know if you recognize it.

LOL I don't know what it is either but it's a cool shot.

No idea Bruni, it looks like a lot of metal.

[Susan Wakely]

Certainly a chunky bit of machinery.
