I'll even add that anyone who gets in that machine and drives it anywhere at all with a person on the forks at full extension does NOT know what they're doing on a piece of heavy machinery.
Will everything be fine and you live to tell about it? Most likely. But it's considered VERY bad practice in the world of machinery and would get you fired on the spot from any real jobsite.
I'm kinda' goin' off about it cuz you could just as easily rent the right machine. That's the wrong one.
Also, that SkyTrac needs it's outrigger stabilizers to be down when operating at full extension. Driving it at full extension is very risky, it should never be done at all but if you do it anyway at least there should be someone who really knows what they're doing at the controls. But of course, catch-22, said professional wouldn't do that.
Too much is not enough, and when in doubt double it.
