agreed. when i say 'crane' i meant the modern, powered, heavy, rolling down the highway version of it.
its like when i mentioned to an engineer friend that i'm doing a bike ride this weekend. 'how far' he asks. 'around the lake' i say. 'wow, how many miles in a day?' he asks. 'all of it, 188'. it changes the reference point.
his reference is wonder, much like mine when thinking about cathedrals and stone and timber and barns and moving really heavy things. it can be done. has been done. and much of it was human powered. wandering around florence in 2006 blew my mind. all those things i studied in school, life size and larger. simply amazing.
dl, people climb everest 'because its there'. you can do the same with these trees, but i sense that you have a purpose and goal in mind.
seems like a cool project...
