Partially failed trees create puzzles for us arborists

[danholls]

This had been the first decent failed tree we had dealt with in a long while and I forgot had much more complicated it makes things compared to a regular tree removal. There are forces and pressure being added in many places, some of which are hard to predict.

In this video we were faced with a Scots Pine tree with a huge stem that had failed onto an apartment building. The tree was still partially attached at the point of failure and the tip end of the stem was resting on the roof of the building.

Partially failed trees are always tricky as you must never assume you know where pressure is in the stem, and you don’t know how wood will react when you start cutting.

We called upon a lot of our rigging knowledge in an attempt to avoid any unexpected movement, dropping of wood and branches and to keep everyone on site safe.

We used 3 rigging systems, double block rigging methods, 5:1 M/A haul systems, and we explain our plan and process as we go.

 

What is the trickiest failed tree you guys and girls have had to deal with? What was the situation? What methods did you use?
