X Rigging Rings, thoughts

[RC0]

Fair enough, I tried to buy then in HBs before Christmas, but they only had the rings "loose" which disappointed me.

 

Well hopefully that'll change soon enough.

Dont get me wrong I think the X Rings are great and would use them all the time if I had them, I was talking about a question mark over a specific application.

 

Does this help? I'm talking about snatching/catching this section to a dead stop as soon as the timber hits the rigging - at the point where everything pinches up tight - greater force between A and B, less force between B and C because of the friction at the X rings (B)

 

I can't see that anyone has addressed this question (but I'm not sure where first names between folks that know each other are used rather than login names.)

 

I see your point, not sure I could do the maths that applied to the loss of 'whole rope length load dissipation' between B & C as a percentage of the friction applied at the X ring in comparison to not having any friction like with a pulley? I'm not even sure I can express it adequately in words (but your diagram does!!)

 

Reg (I hope you excuse me using your first name Reg since I haven't had the pleasure of meeting you!) recognises the advantage of adding an element of friction as a load reduction at the bollard so it's clear there is an element of friction, it must also follow then that the the question you raise is relevant - but how to work out how relevant?

 

That's a teaser!

I quoted/addressed Tims post earlier. Didn't solve anything, but I addressed it.

 

Use my first name by all means. The forum name has no relevance really. I just used it when the forum started, and left it alone thereafter.

 

I'd say, relevant enough:001_smile: hoes that ?

 

Some situations/trees more than others. I've had my share of heart stoppers over the years. So, if it gives me an extra margin, it's better than no margin. When you're up there alone making that back cut is usually the time when you're glad you did.

 

And I should say, none of this is news, or new ground....but the x rings/slings lend them selves very well to the predicament, while before the options weren't so good.

I'd use them if i'd had them sent to me for free, but I didnt, and wont be getting them in the foreseeable future due to being slow. We have 3 pulleys, pinto rig and two ISC, which get the jobs all done fine. And we do alot of rigging! We do alot of natural crotch rigging, with Forestry pro 13mm rope, and it lasts very well. The pulleys only come out on big trees, and wood rigging.

 

Good vid though Reg, I liked your xmas, I mean surfing sweater. You should come here, there are some great waves to catch mate, and there are two boards in the garage!

You're slow, or work is slow ?

 

Do people surf on the east coast Ben ?

[mistahbenn]

Ha, bit of both Work is dead! Everyones slow here atm... Same last year. Prince to pauper. Don't want to derail the thread though...

Derail all you want mate. How slow is it ? You getting a couple days a week in at least ?

[mistahbenn]

Did 1 spruce yesterday, from the bucket, ziplined most of it over garage and wires... Last week we did 1 1/2 days, pruning some big oaks.. Dont see any other crews out either, and even the dump is dead quiet, from 15 guys in summer to just 3 machine ops now.

 

Got offered work in Florida, but thats a long commute Tough place to be.

Got it! I didn't realise Scotspine name was Tim..... (Had a Laithwaites delivery yesterday so bottle of red done, not reading straight!)

[TIMON]

As the title says.

 

 

 

Unrehearsed, so not as articulate as it could have been. Some pointers to consider at least.

 

 

 

 

 

Nice one Reg.

Presumably you use one set of rings at the high point and then the second set moves around the tree with you as you work around it?
