X Rigging Rings, thoughts

[Gray git]

But in theory having some of the friction at the skinny top bit is actually reducing the presure as it's reducing(slightly) the 2-1 caused by a pully system.

Correct me if I'm wrong but isn't that partly why David x man has been developing the tht 3 ring block thing? Also watched a good kiwi video with the porterwrap at the top of the tree for the very same reason...

Correct.

I sort of get that, just need to get my head round it. The rings would still be 2-1.

Those Kiwi boys are upside down remember.

 

All I know is I used to get shaken to buggery doing big lumps with topping down strops, but don't with blocks.

Isn't that because you were using 24mm poly prop and rapping it round the stem so sod all run in the system ;-)

Yes the rings would still cause a 2-1 affect but slightly less as some of the friction is at the top so let's call it more like 1.9-1:rolleyes::what:

There is that....

We rigged out a big fir with a fractured top last week. Heavy limbs 1ft x 30 ft many of them. I had a double ring high up around the main stem, and then ran the line to another single ring level with the first sling by about 3 foot out on a limb to direct the loads away from the stem and hang on the road side. With a block it would be 2 wraps or minimum one and a half on the 3001 bollard....but as it turned out the ground worker did everything with one wrap....which surprised me actually. But by spreading the friction in such a way was reassuring as i couldn't tell the extent of the fracture, and we were hanging some big limbs up there. In theory it might sound like a lot if fuss about nothing....but when you use them the benefits become much more apparent, as does the ease of which the ground worker can smoothly control the decending limbs and logs. With lighter stuff where with a block you might still need a half turn on a bollard, a set of hands with usually suffice.
