nasty failure

[elicokiz]

Came across this Acer partial collapse today; whilst discussing the safest way to remove the hung spire thought it would be intresting to ask you guys what your strategy for removal would be....we thought about c4 but where unable to source any ......the tree is situated in a woodland edge and has clear signs of considerable basal decay, the supporting tree is showing signs of partial root plate failure as well as considerable compressive forces within the canopy... any comments?

Winch it off on a redirected pulley, perhaps

Thanks David, we got one of the guys up one of the ajoining trees to get a high attachment point for that specific purpose, however there is a large fork on the left hand side of the hung spire which completely locks into the canopy of the supporting tree.we thought partial removal of the very top of the hanger may be an option but I am rather hesitant to allow climbers to remove sections from within the crown without securing the damaged hanger which is about 1m diameter at the base.

What about 2 redirect pulleys to basket lift it with a tag line to pull out?

Step cut and winch.... ask dadio it works

Thanks Tommy, i'm liking that idea :thumbup:do you think using the remaining spire for the pulley attachments would be a viable option?

you'd need balls of iron to stand up and step cut that surely...where would you attach yourself if the hanger decided it was going to send you for a earthward trip???:001_smile:

Round the back of the remaining stems..?

 

Isn't there a nearby tree to use as an anchor to "bail out" ?

Nearest bail out tree would produce an adrenalin based rush to say the least ..forget red bull giving you wings? ...this needs explosives??:lol:

I had a similar one with two trees just too far away, so I run a skyline between the two trees with an anchor in the middle, it was one hell of a swing but into free air, was really good fun

 

The only problem is you have to remember you swing back towards the danger zone
