Jeez. Unless it is full of improperly torqued screw type terminations,
there is NOTHING in a simple shock that would damage ANY CNC "electrics"
as you call them.

They can handle like 40Gs, Just like a hard drive can. They can
certainly handle ten, and unless you dropped the ****ing thing, you
cannot possibly shock a PWA to that degree.

"Physical shock loads" is a bunch of crap too. They get subjected to
physical shocks, which get transferred across an assembly, but their is
no remnant "load" or anything else. If there is, the entire damned thing
all the way out to the containment case for it is designed wrong.

You would have to drop a machine from a foot in the air to cause a big
enough shock.

I would be hiring new material handling personnel if they were not able
to move a few tons around gracefully enough to keep from damaging any
electronics contained on the load.
