True, they are monstrous machine. I like to separate those machines from machines that make other machines. I speak of machine tools like lathes with a 72" swing and 60' between centers; forges for making anchor links; saw mills that can handle trees 6' diameter. I put them in a separate category as they are used to make other tools and the monstrous machines shown

I agree Ron, the featured machines are monstrous.

Another singular machine that came to mind when reading the intro:
Weighing in at a whopping 495 tons (450,000 kg), 236 feet by 350 feet by 66 feet (73 by 108 by 20 meters), I submit for consideration the International Space Station.

... but if you consider the ISS as a space-ship, it's tiny when compared with some ocean-going ships.

Very good point JohnDG. There are some real iron monsters roaming the seven seas of the Earth.

Back in the '50s the US built huge forging and extrusion presses for aerospace that I think are still in use. 50,000 metric tons of forging capacity certainly qualifies as monstrous!
