I've always been curious about the liability incurred and who takes responsibility for a situation like that one, or others.

As a climber, if the crane operator signals me that the load is safe, I cut. If I think he doesn't have a handle on it, I usually reduce the load.

My pet peeve is an operator that doesn't use outrigger pads. I wonder if that was the case here.

you are so right blaster,any good crane driver usually not the fat ones will pig sty there pads it can mean life and death especially if its not perfectly flat
 
i think all the fault goes to the tree service, the crane opr.
could not even see the tree you got to wonder if they even had
a log weaight chart , you should know a cranes cap.befor
you even call one
 
I disagree.  The operator (who may or may not have been the driver) is the one who pulled the lever.  It was his responsibility to ascertain the competency of the people on the other end.  He chose to trust them.  Why are we assuming he didn't have his own person on the other side of the house directing the action?

Never have I seen any rubber-tired cranes/hoists, except for very small ones used for spotting components at a construction site, work loads without stabilizers set.

Asking for money early, tip the hand; unless crane needed such and such a huge deposit or something to setup i think.

i think there is enough blame to go around; mostly to operator. Operator look like he mighta been working blind unless crane not set right; my first move is to cut green and gain eye contact at every station. Climber might not be full aware what the crane will do stretched out, crane operator should. Both the operator and the climber, or boss should clear each other in some way.

i agree it could have been outriggers/pads not set properly/zeroed; anymore ours don't run without outriggers out and zeroed; pads is another story. That much stretch boom had to be low angle/high leverage, but crane left straight path thru house and boom is only bent to shape of ground after. The other factor that might have saved the day, if boom itself didn't fail, is counter weight on far end of crane than boom i think; but pads on the boom (compression) side are essential as they would inherit the boom load and the counter pull of weight on loading.

i think of rigging from above with a trees architecture as supports, as fixed boom rigging; converse to, but also comparable too; moving boom of crane. The same lean to load i might fear in a crane, transfers directly to tree loading factors in the fixed, not pure vertical boom sense of a support of tree used,a nd double loaded at closed angle of non-frictional redirect(pulley).

i 'd imagine 'bout any climber cutting a limb and having it and 100' of boom crash thru the tree and house ; banging ground- would respond by coming down soon as stuff stopped shaking and making sure all parts are functional of self and nylon highway before descent to change britches and contemplate just what could have happened; in the real worse case scenario. i'd imagine the workday was done anyway, rope could be considered evidence.
 
im not condoning crane/tree work but there so chalk n cheese if you have respect for it you will be ok,you only have to get the wrong crane driver and a little she will be right to have a big stuff up
 
After listening to Steve Chisolm speak in Sacramento, along with Lamphear the gist of it is responsibility will fall on the tree company. Its not the crane companys gig to figure loads on a variable like a tree. even trying really hard its difficult to calc lifts, and I do it alot sometimes I'm off as much as 25% its easy to get that boom moving alot and many of the sites we have a crane set up in are less than desirable, go look at a few big construction sites they are quite abit more regimented in site location and setup

In "avatar" format it's not very clear what the point is.  If I hadn't seen the "original" I'd not know what it's supposed to be.  The old one worked admirably at that size.

Frankly, I don't see their point, so don't look for one here.
