Choker bells?

[flushcut]

I was wondering if anybody has seen a chocker bell for use with rope and if so where to get one? I saw something similar in Fundamentals of General Tree work but have not found one. The one I am thinking of has bolt for the attachment of a eye. Thanks

I suppose any logging/rigging shop will have some laying around. I still don't see how you will get a nubbin to work though

No nubbin a spliced eye that is connected to the bell by a through bolt. I had the idea when I was pulling over a bunch of trees and has thinking about the bite and ways to reduce it by increasing the bend radius.

How about smaller cable? I run a couple 1/2 or 7/16 chokers

Wasn't Choker Bell, Tinker Bell's evil sister?

 

[Thor's Hammer]

Didn't their Father Invent the telephone or something?

Ok so nobody knows what I am talking about. I will keep looking and let you guys know. I think it is Tinker Bells evil sister.

 

[MasterBlaster]

I don't even know what a chocker bell is.

Just looked through Jerry's book, but could only see a cable choker. No doubt a dumb question, but why not use a shackle with a clevis pin?

 

[sotc]

This is a screwy bell which is similar to a choker bell

 

[Old Monkey]

I know what one is, I've just never seen one for rope. I think there's a good reason for it too.

 

[sotc]

A snap on the termination and a floating ring could work

Seems like a good idea. I'd think if you can fix the eye of the rope on the pin with something, say rubberbands, prevent the the rope from misaligning on the shackle or spinning the pin out, you'd be in like Flynn, whoever Flynn is.

What are these used for, and how do they compare to a standard choker?

 

[sotc]

Guy lines, they are like a removable choker bell only much larger. Thats for 1 1/8" cable

 

[sotc]

This is a double ender, for joining two guy lines together. Neither of these bells are good names to call someone but the double ender may get you in a fight

Look on page one chapter one bottom left. That is the one I am talking about but have not been able to find one in all of the places that I have looked.

Perhaps in a museum! You dont need a nubbin with that bell

What about just wrapping the stem a few times to the point where the friction of the wraps is doing all the work, then tie of the tail with a few overhand knots. I think is what some rescue teams do. Not much risk of mis-tying I guess, and no efficiency reduction from a knot.

I had the idea when I had a job pulling over 10 trees. I set the line with a big shot tied a running bowline up, hooked up, and pulled. The tree was on the ground in less than half an hour. Is what got me thinking about this whole thing was when I untied the line and saw some deformation of the line and some very light fusing of the line on the last heavier pull. I remembered General Tree Work and seeing that pic, so why not use some sort of "bell" to spread out the load and bite. Bear in mind keeping it within SWL. I mean some rigging lines have eyes in them so why not capitalize on them where you can. A bowline by itself weakens a line by what 30% or so and then you add in the bite of the two together you are down, by just a guess an additional 40%. That eats up the SWL of a 3/4" line pretty quick. The closest thing I could find was a choker sleeve in the Skookum catalogue (a link from ACME Rigging and supply) and the smallest they had listed was for 7/8" cable. Which I think will work on 3/4" line as long as the working surfaces are smooth and free of sharp edges. Maybe use a steel thimble and some file work. I would really like to find the one G.F.B. used or at least where to look. I think, when we can, no climbing and just yank the sucker over quick and dirty. Yes, I agree that hiking up and taking wraps is the strongest but not the fastest as they say "Time is Money" so why not split the difference. Then to get the proper alignment of eye and bell in relation to the trunk tie a throw line to the bull line a foot away from the eye and adjust from the ground like flying a stunt kite. Sorry for the ramblings but it is what comes to my mind sometimes.

Ramblings are cool, we speak rambling quite well around here.

 

[flushcut]

I feel better.

 

[MasterBlaster]

Ha.

 

[Angus]

If ya gonna handle lots of cable, bells are the go! We run them on our (7/8") and (1 1/8"). Shackling the kinda cable 50' up mature wood just isn't cool.
Most crane and heavy lifting suppliers still stock bells. I don't know if they would work too well with rope though... and it'd be kind pointless. They wouldn't slide properly.

 

[flushcut]

How wouldn't they slide properly? I am just wondering?
