One of the first things we were taught was to never move the base with
the boom extended up. That gives it a very high center of gravity.
The story is a bit misleading as it is more of a case of the one wheel
"falling through" an access cover than "running over" which gives the
impression the other side was raised.. It may have dropped only a few
inches, but with an arm that long raised that is one whale of a lot of
leverage and momentum. And yes, I'm speaking from the experience of
rolling one over on it's side.

Roll over...yes, they are easily rolled, but collapse. I've never seen
one collapse yet although I'm sure it's happened..
