I have an interesting job coming up, pics to come on Monday.
Hybrid black poplar, 48"dbh, 45 degree lean on stem, all of the crown is on the side of the lean, so very heavy weighting. I would estimate the whole tree weighs 12-15 tonnes.
Having felled one or two similar trees, I am expecting decay in the buttress roots extending up into the lower part of the stem.
It is in wet ground, and has settled into the lean, but started reactive growth in the crown, so its been in the new position for several years.
I can't fall straight to the weighting, there are no expensive targets but it would be a royal PITA to clean up, and future work depends on getting this one right. The best direction is at 90 degrees to the lean, but the hinge obviously wont hold if I just faced it up and pushed it over.
I can climb and rig to reduce the crown or remove it altogether, and just fall the stick. This is what my client (another contractor) has suggested I do, but the final decision is mine.
What I am thinking is to guy the tree using multiple 16mm DB lines, tensioned with a tirfor, directly against the lean, and then use the tirfor to pull the tree into the lay.
Am I nuts?
