Vertical climbing tank rover
Daver...
... you got it! Only prob w/going to four wheel/blade drive vs. tracks is how to steer? With tracks I could, if necessary, silicone tacks of some sort for additional clearance & traction. Naturally, Dave, there are a variety of devices which will shoot a tiny lead filled "shot bag" thru the desired area. BUT overshooting/undershooting, getting thru dense foliage has always been a problem wth these type of devises. Having been a climber since 18 (now 44), I've always dreamed/fantasized of being able to simply "drive" my line to my desired destination and back down. As far as cutting power and simply lowering the vehicle via it's own weight, yes, this would work in many but not all trees. Some are so densly congested you can't even see thru them unless you're right next to the base - even then sometimes NOT! This unit would only apply to certain trees, but the majority of them, yes. Any further input would be most appreciated.
Mucho thanx to all... Cordially, Ralph Ivey
