Crane tip-over.

[jomoco]

Well, as you can see here, that's not what they did when they lifted the log out....But those of us who guessed its weight were way way off, it weighed 12,100 lb!! So, the main screw up was not estimating the wood weights before the job started. I can see in the enclosed photo that the piece is much larger than earlier photos made it appear.

Now, vet, I still don't agree with your method for that piece of wood, given its asymetricity, and the fact that it wasn't vertical, and had that arm off to the side. However, by slowly picking it to vertical, as I described, the main advantage is the load moves closer to the centerpin, and there's no shock loading at all. Having two chokers near the top, opposed, would prolly be fine, but it would still need to be cut the way I said...or perhaps better, with a face cut first, then, yes, wedges if needed, to bring to to as close to plumb as possible.....IMO of course..

And, all this kibbitzing is moot, as we now know they were picking twice what they were rated for. TWICE!!!!!

Nice detective work RB!

Maybe this incident will eventually lead to arborists and CO's using a green wood weight calculator on the job in real time?

I did a bit of detective work myself and found that a full set of CW's for a GMK 5160 weighs over 100K lbs!

As with most incidents, it is usually a combination of errors that add up and cause the accident. Thankfully no one was injured, or worse.

also noticed in a new art. posted by RB that they are now identifying the tree as a "diseased tree"

"the weight of the diseased tree upended the 175 ton crane".....

likely a lot of posturing going on here now for liability and political correctness.

All of it will probably take the court system to reveal a semblance of the truth.

The first causality is always the truth.

Yeah I noticed that too, thier must be a lot of folks questioning the need to take that tree out.

I can easily imagine that piece weighing as much, Live oak is extremely heavy.
However seeing it from this angle I still don't understand the need for all those doglegged pieces in milling it to lumber.

evidently they were not very concerned about the weight being so close or they would have trimmed it down more.

Now what I see is; I would hate to be tied to that in any way shape or form. Knowing the problem could have easily been mitigated by cutting smaller pieces and can't dream of the way they must feel after displacing their customer. In other words, I would hate to be him. That hate and fear is what makes me slower, as; fast is not always best as I have said so many times and here is proof.

Are you yet another victim of instant karma Rope?

I have it on good authority(TV), that these unfortunate victims are not to be referred to that way!

They were both highly rated experts, who both miscalculated at the same time.

Yeah yeah, that's it, see?

Man I confess I nailed a fence a time or two and fell into a septic tank about 24 years ago, backed into a shop, light damage under 8 bones. That be the extent of it bro. Sorry I do not rate them as experts quite the opposite in my rating system but ya know

The proof is in the pudding ..

If a 175T unit had been sent out instead of a de-rated 175 ..that machine would have handled that chunk at 130ft..Even with the first jib on it would have still handled it at 130fT...as a full 175t unit

Reliable learned a lesson ..despite best efforts ,it's still Mother Nature and she's a #####...next time they will send it all..

You can likely bet on that ..the argument will only last about 10 minutes..If it was a true crane specialist sent in from OSHA..A guy would have to be blind to not see that crane wasnt configured to handle that lift ...now that its weight is generally known ..Osha will still have to haul it to a certified scale to have its weight determination stand up in court ..

Im wondering if that thats a gross weight not the tare ..and the press went with the bigger number for the flash ..I say that because theres seems to be a little argument about the weight versus whats pictured..in some previous post


You guys know better than me ..looking at the picture again ..any way that log would hit 10,500 ..assuming the reported weight was with about 1500lbs for the block and rigging..

That log very likely could hit that mark or a little over. Logs that size when using my grapple truck have to be cut in six foot sections to load and they are stihl very heavy and have to pull them to the truck to lift. Thing treevet was meaning I think is; the tree likely was not diseased and likely not a true danger with appropriate guying and pruning.

I think we are going to see shared responsibility in this case but if it is ruled malpractice, woe to the ca that might just release the co from any liability. One thing is certain, I would be having everyone p tested, as it seems drugs may have been at work on that one.

Lets not get you started on the pee cup again rope. :hmm3grin2orange:

Speaking of testing however: Does anyone know if its too late to test that tree for SOD or whatever this atlas guy was claiming the tree was so "sick" with??

I p'ed in one two days ago lol. I could sell my p to all the hiding hippies for mucho denero! They would need lab work.
