Most of your larger punch presses are indeed final assembled on-site. Sometimes the base for the press would be set 5-10 feet or more deep into the concrete. I understand really big presses are sometimes set in a pad that sets on bedrock.

I used to work with Minster Piece-Maker punch presses. 100 ton and 150 ton presses, we'd run at about 150-200 strokes per minute. We/they had a 300 ton Niagara press that ran at about 40 strokes per minute most of the time, unless we were running particularly thin material.
