Why don't we wrap the pull line around ourselves....????

Might add, watch around the feet too.

It doesn't take an experienced tree worker to figure what could happen if you wrap a pull line around your body.
 
Yep, that was just a train wreck from the get go. Lucky they got away with so few injuries.
Lines through the hands then away from the body and feet. These guys just didn't have a clue about the physics they were dealing with.
 
Even from this angle you can tell the thing is leaning the other way... and that line was never going to help it change its mind tied that low - not that it would have made much difference without more pulling power. I can't stop watching this... That guy is really moving through the air!

I was going to say that it's amazing there aren't way more videos of this exact thing happening, but there are so many things that need to be done wrong for this to happen... no wait, it is still amazing there aren't way more videos of this exact thing happening.
 
The reason why there aren't more videos? it's because that which can go wrong usually doesn't. Bet they have done something like this before and it went o.k. Bet they expected this one to go o.k. right up to the point where it didn't.
 
Yeah experience can be a great teacher. But in tree work, if you successfully do something the wrong way over and over, it can be a deadly teacher.

what happened to the climber? it seems like that dude gets folded too.

rookie mistake, shoulda had a heavier guy on the ground

You shouldn't switch out ground guys when your pieces change size. Grab that porti and the smallest guy you have can catch anything if it's used right.
 
kevin you were on the right track, I thought they were trying to lower that out at first until other people started breaking down what happened.
was just playin around with the heavy ground guy thing. thought they didnt have wraps on anything or something like that
 
All I can say is MA and higher tie in but yeah MA. Does anyone know how much pressure it takes to get the slack/ stretch out of at least 150' of 1/2" rope.

I believe its at least a 3:1 ma. For an average person
 
It's not to take the slack out but to create force that will exceed the inertia in the piece once the holding wood is removed by the saw. Consider the rope as a spring under tension, the chainsaw as the release mechanism. The spring wants to release the tension and resort to it resting state. When we calculate forces there is generally assumptions made to keep the math simple. No friction and an absolute static pull line, i.e., 0 stretch.
 
Holy crap! That dude really was moving. Is it just me or did he and the log almost impact each other in the air while flying toward one another? That certainly would've meant more severe injuries. Imagine being the third guy on the crew, possibly simultaneously having two seriously injured coworkers on site in a matter of seconds. One in the tree, one on the ground. Definitely the best illustrated example of the dangers of all the mistakes listed above. Thanks for posting.
