Default Used C Frame Punch Press

I'm looking to buy this Roper Whitney, I believe it a model 218, 4 ton with 12" throat. I am concerned about the possibility the unit has been overloaded and deformed. I know people sometimes use cheater pipes to try to punch holes that are well beyond the capacity of the machines they are using. Will this bend the frames of machines like this or is the punch travel small enough to prevent this from happening?
Here it is: https://www.roperwhitney.com/bench-deep-throat.html

Aren't energy consumption and computers supposed to make life less stressful?

having looked at some pictures of the said model 218, since none were supplied... I conclude that if it were used with ... extra leverage, then likely some of the moving mechanical connections would show the abuse, not the heavy duty C frame.

I hadn't thought about this, it seems rather obvious now that you mention it. I'll be looking closely at the pins and linkage for both wear and deformation, thanks.
