WOW that is fubar.....
I thought I would add the picture of the crane in the house. What a mess
boy this shows how some people should not be in the tree service industry. the thing i see is a tree crew trying to do more then there equipment could handle. the crane was the type was not able to handle the load be hooked to it. a second big problem is the operator screwed up royally he should have check each piece and had the final say if the piece being cut was to big. this is one reason i do not trust arborist when they cut on my land, i am very anal about how trees need to be removed. i have seen to many tree service company's that hire chainsaw hackers not surgeons. just go to show you get what you pay for.
The crane operator is responsible for EVERYTHING that happens with a crane. He has the first and final say on it all. Tree service guys take the tree down, crane guy hauls it out.
Before jumping to anymore conclusions and finger pointing.
How many of you guys are qualified crane operators? I have been for going on 12 years now. How many of you have been operating a crane that has been shock loaded? I have and it's just about the worst situation an operator can be in.
You can be picking a load well inside the limits of weight, angle, and stick length and if it shock loads this unfortunately can and does happen. Depending on how bad the shock is determines everything. As an operator you can tell when the load is to much, mechanical strain, boom flex, whip strain vibration, getting light in the seat, over weight override. Even when happening in slow motion the operator is next to powerless to stop something like this once started. About the only thing possible to do is E-drop the load(not always a fast drop) and/or swing away. Both in hopes that the shock energy is slowed or redirected enough to stop the this outcome. Not knowing anything other than what is printed I'm not sure I would have done anything different. The house was empty, there is a man in the tree and presumably grunt(s) on the ground, both out of site line by looking at the areal photo. The climber would/should know better than to be in the direct path of the load as well as the grunts, which right above the load is the machine. Not being able to see them and knowing there is an empty house I would opt for the house instead of possibly dumping the load onto or swinging the load into a body that I cannot see and possibly killing, crippling anyone on the ground be they either worker or neighbor. The ending could very well have been part of a last ditch emergency plan.
Loads shift, loads and rigging break, boom structure failures and shock loads can and do happen for any number of reasons. Riggers rig things wrong even when instructed exactly how it is to be done. More than once I have fired an oiler for not following exact directions and not knowing until the load was is sight and I knew what had been done.
This is a bad day bar none. The operator gets all the credit both good and bad just like any other job skin, bull or side rod out there. Believe it or not, in this case the credit may be good with a very good out come of lives saved. Property damage is secondary to human life. I'm looking at this from a different point of view than most though.

Just eyeballing the pic, it looks as if maybe the crane operator mighta been working blind and on communications with somebody on the other side of the house. Now that leads to wondering if it in fact wasn't just a Comm error magnified by the climber snipping the drop before slack was taken in, on a load that was misjudged in weight by the guy acting as the crane operators eyeballs....
I dunno. I wasn't there, but can see where all manner of simple error could be easily magnified into the mess in the pic.
Simple and clear communications is usually the culprit in most errors though.
Stay safe!

It appears from these last pictures of the cutting that he did not do a back cut on that big piece tha
this last pic before the crane fell
and the last piece that made it over successfully
the one that caused the tipping
It was too big of a piece, and too much slack to allow it to fall away from the house without a back cut or hinge to slow the momentum.
Id blame the person that tied it on and cut it. Is the crane operator to view and approve every cut ?
