Cable Bracing

[Arbocop]

wow

 

i love bracing and propping bit of a passion of mine and it must be said that the yanks and germans are way ahead of us in this area.

 

whats interesting is the description of the systems above regardless of anchor (invasive or not) is the fault stabalising and the failure prevention systems, .

 

what is interesting to me is the lack of reasoning to install the brace and the reach for cobra, there are many other systems on the market with differing propeties to cobra.

 

personally i always consider an assessment of aminity and nett safty gain befor even installing a brace.

 

with non invasive bracing the time of year issue is not that critical but god instalation of a well speced system is.

 

just some thoughts

Yeah I gotta say I find the whole thing quite interesting.

Very much with its feet in the world of mechanical engineering and load/lever calculations. Not always as immediately obvious as you might think. I would be interested to know if there are any courses that address the principles and methods of the science. A current best practice....

We use the Gefa system and products, they are really good and much better than Cobra, cheaper too...:wave:

I have seen that stuff and it seems simpler to install. I am trying to specify it for a job.

I had heard the cobra bracing can wear the cambian on the tree, has anyone else heard of this happening?

Yes and seen evidence of this too. I think too many people get hung up what damage can be caused to a tree by cable bracing, afterall you only should be specifying it when the only other option is felling the tree etc.....

 

Cable bracing is not a solution to tree safety or health, it is only a way of extending a trees useful working life..

ive never seen any damage but i always install my systems not too tight...been back to inspect many and never seen any major cambium damaged,maybe a bit of rubbed bark but not major ingrowing cambium damage.

I have tho witnessed failure that has not resulted in catastrophic damage and all thanx to the bracing system holding together otherwise fractured and fallen trees/limbs... Or is it all about preservation for you??

Apparently, the guy who invented Cobra has left that company and started a new one called Arboa http://www.arboa.com. They have lots of things on their site and have answered my questions in the past very efficiently

Several years ago I got called to a property where a Horse chestnut had split in two, one half went across the pump house and swimming pool, the other went back across the neighbours shrubbery. It was a twin-stemmer, and the invasive bracing had failed in strong winds.
