Finally, I see one example of how an adjustable bridge is advantageous. Easier to step into the saddle. Yet the extra rope leaves me wanting. Or not wanting. Lol
The logs we did on this job, we had to keep off a slope above the house, a service line and a manzanita the HO wanted saved. Having me mind one rope while he did the other and the ability to swing the top or log some by hand while I minded the lowering rope was good for this one. Basically using...
Another point about drift line set ups is less personnel needed. Rob and I have taken down 100 plus foot pines, just the two of us, with a proper friction devise worked by the climber a loft after the piece was caught by ground man. The he takes over on the drift as the climber holds the...
And as pointed out, the drift set up is simpler, and i use that wayyyyyyy more often. Just have to watch your side loading when winching the piece toward the winch point while feeding the load point rope.
Its actually pretty easy to first catch the piece on a block, and then use that line to lower into the high line. Often times, just slack the high line, catch on block, then tension the high line. Granted you have already done the rigging into the pulley. But the piece can be held by porta wrap...
That large SS pulley is a 20,000 lb rated CMI if i recall correctly. Will take a 5/8ths line and is under 100.00
Ive done this with the little CMI pulleys guys use for hitch tending that are rated around 5k for really light loads or zip lining heavy limbs that dont exceed that 10% load.
Indeed. Easy to install with throw line. Set some foating blocks. High line can go through a crotch above and basal tie. Easier set up with a trolly, but you can even use CMI pulleys that are very reasonably priced if the loads are small. I shared that yarding system i did recently on here...
