Hey Dan, I have seen where a reach truck was traveling rather fast, in the forks first direction, while raising and when the carriage struck an overhead crane, the truck flipped backwards, I was told the operator lost a leg.
(we aren't talking about "proper operation". we are discussing -emergency- egress of stand up operated narrow aisle equipment).
The forklift, once back upright, a new battery installed, washed down the spilled acid, and lost almost no hydraulic oil, worked well for many more years, never complained of guilt.
