Custom spring loading machine. From a precision machine shop that went out of business. Frankly, I don't entirely know what this does, but it seems like it would be used for loading large springs into/onto something.
The component parts we can identify are: -Balluff BES IKV S4 025 NS 1 Y (cheapest available price per PicClick is $249.99)
-GMB 42BYG023 (a Bi-Stepper Motor costing about $20 individually.
