[TowerTalk] man lift tips over

[Marlon K. Schafer]

Yeah, I'd have to totally agree with this.  Moving them, especially the big 
ones, is just too dangerous.

I don't have the math on me right now, but even a little 6" drop on a wheel 
translate to a HUGE movement (probably in a bad direction) 80 or 100' out.
