    Wolfy dead fir zip line and crane

    Perhaps you missed my point. There was no room to crane limbs attached to the logs. And no way would we have wanted to catch a 35 foot dead top, and stop it. Plus doing something like that would have meant a number of branch pieces falling when the top was caught, and laid into that canopy. No...

    Wolfy dead fir zip line and crane

    You'da been payin for a 90 ton crane to get enough reach..or at least a 60 ton. Either would have broken the driveway, not just put a small crack in as the 38 ton did....and added at least 600$ to the crane bill. Plus, as I said, it was impossible to crane with limbs intact on the this job.

    Wolfy dead fir zip line and crane

    Yes, he was near the top at ~120 feet after zipping the top and lowering two log sections. Dave choked it off at about 110 feet, if that. Lost some reach with the long choker, which Dave could have wrapped a time or two extra. Didn't need to, as he had plenty of butt weight in that first 31...

    Wolfy dead fir zip line and crane

    Ummmm, Ed, the tree was 155 feet tall. The crane has a tip height of about 135 feet, and about 115 or so at that radius. Plus, it was easy to zipline those limbs.

    Wolfy dead fir zip line and crane

    On day one, I shot a line to 85 feet or so, Wraptor'd up, then ascended to 110 feet, where I set the spectra speed line. We needed no control line to zip over the house, as the first limbs were about 40 feet up. On my way down, I preslung a few limbs, so as to keep the speed line reachable...

    Wolfy dead fir zip line and crane

    Just got home from craning a 155 foot tall Douglas-fir over a house from 50 feet away. The last crane pick of the butt log weighed 8100 lb, exceeding the 38 ton crane's load chart at that radius. But he got it--up and over the roof. It just nudged the gutter on the way up. I knew it would be...
