Al, what did you do for safety on that build? I don't see any light curtains in the photos, did you use 2 hand trip?

Here in the US, all power presses are required to have at least one of 2 safety systems.

One system is light curtains, which prevent operation when the operators hands are near the pinch point.

The other system is 2 hand control, where 2 buttons have to be pressed simultaneously to bring the ram to within a quarter inch of the work, at which point control transfers to the foot pedal.

Decades ago it was routine for a press brake guy to be missing at least part of a finger, but fortunately that era seems to be ending.
