Bracing

Paul Whitington

Hello people, Dynamic Tree Bracing Systems
Why are we using products that break down in ultra violet-light, lets look at the job this product has been installed to do, depending on the size, structure and position of the tree, I am replacing Bracing every three to four years. Ahh the old stainless steal cable, yes an inspection and adjustment every two year but not this replace replace replace. No I'm not saying cabling was a better system, there needs to be a system that is durable and does not enter the trees system.
Leave it with you,

So is it just fading or is it actually deteriorating?

Which dynamic system are you referring to? Cobra, Yale, Other???

Paul Whitington

Regarding Bracing, I am using Yale, I have looked at other products and they are all saying this is not permanent product, it is being replaced under recommendation from the manufacturer. load capacity is reduced over time because of the breakdown of the product in ultra Violet light. Has not anyone hared of this problem? Be careful people, be very careful.

Paul, the term "bracing" refers to the installation of metal rods through the tree for support. You are referring to cabling and specifically flexible cabling.

My opinion is that this product is worthless and gives a false sense of security.

Paul Whitington

Yes I know what brace means, The product is called "Dynamic Tree Bracing System" or "Yale Bracing system" or "Yale Brace", I am quoting product name.
Brace: - a device that strengthens a framework, to make steady by supporting, a device that clamps or fastens, to prepare for shock, to make firm, Latin bracchia meaning arms.
I would say the company has looked at one of the above and named the product accordingly.

We have installed a fair bit of both Yale & Cobra cabling & i think if you want to use a dynamic system Cobra is a superior product but costs a fair bit more than Yale.

Both are more suited to lighter duty applications than steel cabling.

I think i have seen something somewhere that used some kind of "sling" around each stem and was joined by steel cable.... cant recall at the moment though.

My def. came from the "Glossary of Arboriculture Terms". Historically, and I go back 40 years in business, support mechanisms have been referred to as "cabling and bracing". I think these dynamic systems fall under the former rather than the latter. I understand your point tho.

treevet

We have severe storms around here that could leave one liable with a weaker degradable system.

I think a steel to wraparound system would crush conductive tissue under load like a girdling root.

hi

Up here in Germany we were using Libre Systems , which were replaced every 5 years

The local Council we do alot of work for have decided to swap all the cable systems to Cobra Plus , because it has a 10 year life span ,

naturally if there havent been any major blows to the system , I think Boa has the same life span . .

Paul Whitington

Thankyou to all for your help, I have used the Cobra product and I will look into the Cobra plus and do a bit more reaserch and let you all know. Thanks again keep safe. Paul Arbormatters
