Do not know what it's called in English

I have always heard them called ring roller or tubing roller.

From small hand-cranked ones like these:

for small diameter solid rod and bar stock

To slightly larger ones....

for tubing, exhaust pipe, etc.

To that monster one you show.......Wow!
Is that in your shop?
Do you know the published capacity of that beast?
Do you have multiple dies for flat stock, round and square tubing?

I found a couple pics of the guys roll forming "I" beams on the horizontal roll.
These are smaller I beams, they can do much larger.

It just amazes me that they can bend these to such a tight radius with a nice smooth curve.

They could do rail tracks of any size the same way.
 
Yup, Italian made. I have rolled 2”x 3” 1/8” rectangular tubing, 4” channel, 2” angle and flat bar on edge. 480v 3ph. Had 10 hours when I purchased it from a locomotive refurbishing facility. The only used it for profiling hand rails. Came with a nice compliment of dies and spacers. I have to use a step up transformer with the rotary phase converter but it works well. Never have rolled coils but seen some cool videos.
 
It comes from a company that went bankrupt
They had sold most of the stuff when i came, and nobody wanted this one so that was free! But I bought a big lincon mig welder so maybe not completely free
