Sorry I have to chime in. If what he is describing as inverting the forks is what I think, I believe I have seen that done in an emergency situation. (only) I know an ol' boy once that had a Yale with a 188" triple who had a pallet to take down that was about 194" up. In his case, some fast thinkin' guy decided to turn the forks upside down to get the pallet down. So, IMO I think the strength of the fork would be the same but I am certainly not an engineer------
