Part of me always thought that explanation as apocryphal. I always assumed the real story is adding a safety factor to a non-P.E. engineered, non-listed component set.
That said I did see a fitter (pipe) hang from an air line he was installing when the platform on forks went over when the whole thing tipped over. Forklift had leaked fluid back into reservoir, and progressively leaned until over center. Of course the telescoping thing was inevitably called a man lift. Best.
