@ Ian - thanks for the info. It really is eye-opening to see the uber-dangerous stuff they have to do to make the steel we use for so many things!

Treadwell was indeed the company name, bobo.

Back in the day you couldn't have dragged me close to those wires. 120 volts (household current in the USA) can kill you, 480 is industrial grade power and will FRY your a** like a bug.

Screwy, I never knew they did stuff like that in a steel mill!

This is why Motts is posting these pictures and I am not. I get a fear of heights on a freaking ladder nevermind climbing up this place.

@Brenda - so there IS a belt that goes overtop of those "stretched-V" rollers. I wondered. I've seen a bunch of these things in my life and thought "How did they keep stuff from getting stuck between the rollers?"

@BKWOntario - almost certainly 2005. I wonder if it isn't some old hand who snuck back in to sign his name on a piece of equipment he used to use a lot.

That's the 'shell' of a big-*** fan blower, usually used for circulation. I've seen them a bunch in various industrial areas in video games and IRL.

An electric-driven fan unit goes in the center, pulls air through a grate (to keep some oaf from sticking their hand in the whirling blades) and whooshes it out the side-pipe you see to the right. Then the air goes through whatever ductwork it's supposed to go.

The bit with teeth isn't used for sawing, those are gear teeth for a rack-and-pinion system to adjust something for size or space, etc.

I'm almost positive it's worked by one of the two big handwheels, probably the bottom one from where it's positioned.

@ Steve - thank you very much for the background. It looked like something that did "top-down" work but I couldn't determine what. And how fitting that the metal to be punched is called a "victim!"
