[QUOTE="millbilly, post: 5133510, member: 8977"] I don't remember LR1, but the first aerial I ever used only had a 270* rotation. That was achieved by a 2 way, hydraulic piston, that laid horizontal. On each end of the piston a 5/8" cable was attached. The cable then wrapped around the base of the boom, kind of like primitive fire starting, with a bow a string and a piece of wood. Now that I think about it, a 120' climbing line you could do 85% of tree without an extension. Now day 150' only does half of them. Trees have gotten so much bigger in my 45 years. [/QUOTE]
