The Mesta Machine Company made large, and I daresay even huge, hydraulic forging presses for a great many years while they were in operation, and were widely used in industry. A while back I wrote a post about the 50,000 ton Mesta hydraulic forging press The “Fifty”, which was built several decades after the dinky little 8,000 ton steam-hydraulic press pictured above. Back in the day, however, an 8,000 ton forging press was a pretty big tool, and the largest that Mesta made at the time (circa 1919) was “only” 15,000 tons.
These machines were the workhorses of many forges through the years as the most efficient way of producing large forgings. I think that they’re wonderful.
