Rigging technique ??


Dean Lofthouse

Recommended Posts

Got a tree to take down in a very very tight spot with a 3ft x 5ft space to knock discs off into and loads of fragile things around.

 

Neigbouring trees are too far away to rig off so thought about doing this so when I'm discing down I can attach the lowering rope and lift the disc off the stem and lower without having to snatch it.

 

Blue line lowering rope, red line to be tensioned and use with a floating pulley above the stem

 

Anyone used it before

done this before in tight spots where the whole zone is patioed works very well indeed you can even set to lines 1 for the rigging and 1 for your anchor :thumbup1:

I have used a similar set up once before - but ended up fixing the pulley to a point in the rope (your red rope) in order to control its position. What caused the re-evaluation was when the tension went on the lowering rope the pulley shifted towards the lowering rope's side - so once the pulley was fixed adjustments could be made from either end of the upper rope.

 

Although looking at your particular problem, Dean, I would just take an eraser to the whole tree in one go! :biggrin:

 

Good luck.

That kind of highline system creates a lot of lateral forces on the anchor trees, and it is hard to get enough tension to control the sagging.

 

Would a load transfer/drift line using the same two anchor trees work?

 

You could use a four way fiddle block for this.

I tried it something similar once Dean, but as Peter says, I wasn't happy with the lateral forces in the adjacent heads when the line was tensioned (they nearly ended up touching!).

 

Reg Coates blocked down a big Ash by lowering 3/4 discs which he had screwed eyes into. There's a vid on here somewhere. Very effective, if time consuming.

 

What's wrong with the decent crash mat / Dead-eye-Dick-with-the-discs option?
