Point of Attachment???

[NickfromWI]

Was looking over the cabling Best Management Practices that the ISA puts out. I've read it cover to cover several times, refer to it often. I feel like I know it pretty well.

Something caught my eye. I wanna run it by the House to see what you think.



That phrase "branch diameter at the point of attachment" could be looked at in two different ways...

1- the branch diameter at the point where the cable connects to the branch being supported.
2- the branch diameter at the point where the branch connects to its parent limb (or the trunk of the tree)

So....which do you think it is?

im guessing they are referring to point of hardware attachment.

I'd go on what I was working with. Actually never did much preservation work. In 38 years maybe only a couple dozen trees, and mostly conifers. Pretty simple. I can only imaging the formulas and figuring for broads tree supports can get pretty intriguing, and costly.

#1 Diameter where the connection hardware is being installed.

Yep, otherwise they'd get all technical and say bifurcation.

hahaha that word would get shot down i expect; or maybe add trifucation and Quadrification... +3 on the point of attachment, imo. nick please send the question to your rep, rich hauer at uwsp.edu or committee chair peter becker of bartlett.

also look to tcia.org under Business for A300; Part 3 Support will be going out for public review again this winter. o and also that table has some other issues if you look further down...

Just wondering but has anybody actually ever cabled a 2" stem?

 

[MasterBlaster]

Why? For training or something?

 

[flushcut]

It's in Best Management Practices.
I have never seen it done, just axin.

 

[MasterBlaster]

I've never seen it done, either.

 

[treelooker]

I've guyed that size w arbortie, and braced a cracked branch that size, but not cabled purr say.

so the bmp mentions it in a size range?

 

[NickfromWI]

I did a melaleuca on monday and it was 3 trunked. 2 were decent sized. One way no more than 3" where the cable was installed.

 

[Porkbrick]

ive cabled a 2" stem. it was a radial system to hold together a small tree that fell apart. four heads peeled out in four directions like peeling a banana. to my knowledge it is still there. ill have to go and check it out now that im thinking of it.

And the masses have spoken.
