Stactic cobra bracing tips?

[Treeation]

Hi got a project installing a static cobra bracing system for the first time in a twin stemmed macrocarpa which already has a crack but tree officer wants to retain with non-invasive bracing.

. Measured the stems with defect and going for the 8tonne system, also aware that the installation should be 2 thirds of the toal height above the defect.

 

Any tips? Especially on pre-tensioning - what is the best tool to do this?

 

Thanks in advance.

A pair of 5ton rachet straps work well for pretensioning, or a little hand rachet winch mid tensioning line if the tree is larger. A spare friction hitch to put on the end of your bracing line so it can follow you about the tree is helpful, as are the usual tools on bits of cord, chunky scissors, insulation tape etc, and a little plywood bosuns chair/swing seat if you're going to be in a awkward spot for a bit (or like me are getting soft).
