I am bidding on a Poplar removal, as part of a 6 tree job. This Poplar is about 75+ ft. tall and about 32" DBH. It is 2' from the ground-level deck, and 2' from the pond/water garden, which ends about 6" from the deck. The pond is in the way of my access to the tree from the side where the bucket truck will have to come in, so I will have a climber take out the top, at least, and down to where I can access it with the bucket truck. Behind it, a distance away, is a sandbox, swing set, and plenty of other trees that I am not taking down. The opposite side of the Poplar has a little bit of working area before you get to the fence. I can probably get the tractor in there and turn around, but it will be tight.
I have plenty of room on the other side of the pond, parallel to the back of the house.
I am thinking about speedlining the pieces down, over the pond to the other side of the yard.
I am calculating the weight of the wood, at the largest point, to be 221 lbs per foot. I am wondering how big I can go with the pieces of the spar once I get the top out of it.
Of course this depends on my equipment, I know, but let's say in a perfect world, with my 3/4" bull rope, how big can I expect to be reasonable when cutting this trunk? I have a 3/4" bull rope and two 1/2" ropes, one a former climbing rope turned to rigging rope.
The speedline will be tied off to the trunk, just below the cut.
I figure I will need to cut it while attached to another rope, attached to the porta-wrap, so that absorbs the shock load when it falls, then connect it to the speed line and let it down, probably using the rope and porta-wrap I used for the shock absorbing.
The perfect length would be 8'6", so I can use it for the sawmill, but safety comes first and I'll take it out in 12" lengths if that's what's necessary. The 8'6" length will be close to 2000 lbs, but I don't know if I can count on a speedline to support that kind of weight, or the shock load on the block and porta-wrap for that weight.
Would I be better off cutting small enough pieces that the speed line could absorb the shock as well as transport it down?
The other thing about the speedline is it will have to go over the bucket truck to get down to the ground.
If my pieces get that small I can just drop them on the other side of the tree, away from the pond, but then I have to get the pieces out of there somehow, and that's why the speedline idea came up in the first place.
Thanks,
Chris
