Cobra bracing

[Treemover]

Mods please feel free to relocate!

 

Hello comrades! I have been asked to brace a large Monterey cypress. The tree has been crown lifted to the sky, with 8 large surrounding stems, and two smaller; with one central column.

 

The tree is quite tall, approx 25m; with all these limbs forking at 3-4 metres. There is heavy footfall beneath and a building adjacent; literally touching some of the limbs.

 

Looking at the cobra bracing; how do you determine what ton system to use. I am just wondering if the 8 ton system is overkill on all the limbs?

 

I am also toying with the concept of using two cables per limb to prevent the limbs striking the building.

 

So how do you determine if your using an 2,4,8 ton system?

 

I know there is a branch diameter, but is there any other rule?

It's done on branch diameter. If you google cobra bracing in Google there's a good YouTube video that explains it all.

 

Just saw the bottom line

If your worried go for the 8 ton, I've braced some monster limbs with cobra but never one that I thought would break the 8 ton.

Is the bracing to help poor unions or prevent the limbs falling on the building if they fail ?
