without reading the news articleHere's a test for you ZinTrees: Tell us the best reason why this crane is tipped up like that. Offering the advice that it was too heavy a load is inadequate.
In hind sight I could have done it better. I really should’ve cross stacked and added another layer of cribbing. My thinking at the time was to double up one way to keep any flex out of the cribbing since the bottom was shimmed. Can’t see in the pic but there is more than just the one board you can see. I have several thinner pieces under there to bridge the gaps. Ultimately I should’ve dug out to make it level first.not a good plan.
highest ive worked in was supposed to feel like 117 if I recall(damned if I could work in the heat some of you put up with)
So PDQL jumps in to warn a few fullas who (justifiably, in my humble opinion) have been getting cheesed off with low value (again, just my observation) contributions to the thread, then gets caught up in the same sticky web that's repelled valid contributors input? This is hands down, 100%, no argument the funniest thing I've been witness to on this site EVER, and I've watched every single page of the WTF section. I'm honestly almost peaking at the anticipation of PDQL's response to the latest offering........Jenga.....my godfathers......
I very rarely post anything, don't really think I've got anything too exciting to contribute but I love seeing how things are done by different outfits and especially the varying environments tree work is performed in (damned if I could work in the heat some of you put up with). I'd be very sorry to see this thread disappear.

That is a giant assumption. It was a backyard operation, and you are presuming that the cutter and the crane operator were in direct communication. Given that the crane is tipped over, I doubt if it was that sophisticated an operation. I have done a few crane assisted removals, and we never had a conversation like you described. Your average climber doesn't know how much a log weighs, anyway. It's all done with guesswork.without reading the news article
cutter said a weight, crane operator said "OK" (without seeing the load first due to house in the way)
piece came off, dropped, and overloaded the crane
Oooh! A crane load chart. I wonder what in the picture (besides being tipped over) suggests that they didn't follow the chart?crane was within the bold line on the load chart (tip vs breaking load)
at certain angles, the structure of the crane snaps before tipping
Nonsense. Cribbing never rolls out when it is squeezed perpendicularly between two parallel forces. Think about Jenga a little bit harder. Those pieces never roll out! The column always collapses due to insufficient stability, but the pieces NEVER "roll". (That being said, if the cribbing is crushed with an overload, it may appear to have been rolled. Crossing directions makes a crushed load of cribbing much more stable than parallel stacks.)your picture shows 1 layer of cribbing, when the side closest to the camera lifted, if it sat down (with 2 or 3 layers of non laced cribbing) there is a possibility of the blocks rolling out from under the outrigger pad
ive played jenga before, with cribbing, ive had blocking like this roll out from under stuff, hence me saying to lace it or dont use it
it was too heavy of a load, crane would be upright if it was light enough
Offering the advice that it was too heavy a load is inadequate.

AFAIK most modern cranes have load cells in each outrigger, if the tires are holding weight then the crane (or operator) would have zero clue when its actually losing weight on an outrigger, because the readings wouldnt be accurate
nopeThat is why your crane company quit talking to you. You threatened them with liability while displaying your ignorance.
got a contract climber, did the job, made more than we would have had the crane actually showed upand you clearly didn't benefit from the experience
That brings up another question: are you here to learn something, to impress us with your bluster, or perhaps just to join a community of peers?
. Man up, and admit that you don't know, or just turn on your common sense and look for the obvious.
Then I'll make a request. Can we please have less bluster and more "here to learn" ?
If you are as young as you claim, then I have the greatest respect and admiration for your work ethic and accomplishments. I sure wish that you would apply yourself to learning more from this forum than telling us about your successes. Whenever you do something great, go ahead and tell us about your project. Then ask for some opinions, and don't get so damned fussy when someone points out their thoughts about your project. We are probably seeing things that you cannot, due to your lack of experience.
As to that crane picture, you couldn't see the problem because of your lack of experience. Had you just admitted that you didn't know, I would have told you the answer. Instead, you submitted a guess, which only consisted of stating the obvious.
So I'll put it to the field of experts that may yet be watching this thread: What's the most probable reason that the crane tipped over?
Kindly don't say dumb stuff like "it was overloaded". We can see that. Tell me what the visual cues are that can easily be seen in the photo.
