Listened to it several times, and right around 02:41 or 02:42 it sounds like a drum getting hit, as though a strand in a cable snapped, then it all lets loose after that.
Just like the 450ton crane dropped on the ship at Port of Brisbane few weeks ago. They blamed rigging failure but they slung around the outriggers, the sharp sides of the outriggers cut straight through the straps.
@gregj.gotham4402 Chain??? So you think chain is stronger than cable, even crimped chokers. You're crazy, ever hear the term "a chain is only as strong as it's weakest link? There is a reason that term exist, chains links are to inconsistent to even rate with a SWL.
I worked 40 years on gold mines in South Africa,we had a qualified rigger ropesman on every shaft and gold plant Every steel sling and material sling had a ring on it with a number A book log was kept in his office with every sling number in it, once a month he had to go check every sling number and sign it off Once in three months the engineer had to also sign it off Wonder if such a system is done in USA
the engine of one of the cranes labnoured hard 30 secs before and the dual lift wasn't pretty/synchronised well. rigging was prob good enough even when slung incorrectly. Shit adds up.
NOT FOR BONEHEADS. The fault lies entirely with the use of straps in these cases. The longer the exposure to stresses the more 'Strands' break and fail. Eventually the straps will fail through deteriation the longer the time they are subjected to these heavy weights. They usually fail as the load is moved or lifted as this is when the greatest stress is put upon the strands that make up the strap. Sunlight can also cause the straps to deteriate. I used to test all sorts of slings and most companies just do a deadweight test lifting a set weight and then measuring any stretching afterwards. Webbing straps were often tested to destruction and the weight that they failed at were checked against the design graph. If it failed within its designed criteria then it passed for use. Unfortunately, the speed of the lift and the number of times it's used would determine whether the sling lasts it's designated lifespan.
The crane on the left turned slight, the weight was more based on the left hand side because it turned slightly to the ship. The rigging also could had more error to count for, maybe 200tons freedom of error could had prevented this.
Yep, something gave up. Normally in lifts such as this, assuming both cranes are identical, if you aren't keeping the load level, it is the end that is higher in the air that goes first. Not the case here. At level the load is evenly distributed, and if you take it to its full conclusion - the load hanging vertically - only one crane is taking any weight. The more off horizontal the load is, the more one crane is doing all the work. But... if this load, even though lifted horizontally, was infact heavier at one (like a spoon perhaps) the weight transfer to one side of the lift is far greater.
😂😂 people blaming the crane operators for leaving it up too long im a crane driver you cant go up down or anywhere until your banksman tells you so the banksman should also check equiptment ie lifting gear .
It's a hard thing to lift and they tried to decrease the wire tension by having veritcle lines from the bar...but the problem is that they still had huge tension on the angled lines coming from the crane to the bar...They were probably trying to keep the angle within 60 degrees but when a wire is under that much tension it better be a perfect wire or it's gonna fail catastrophically....and what was that idiot doing standing under the load like that? I just came back from crane school in Japan and we've just done a full day of accidents and their causes...
Not enough Balloons attached to the Load. 😮
that's what I was thinking!
Best video of a blur I ever saw!
Waste of time until last 10 seconds and then camera man panicked and missed it.
cheap amateur recording
Guess the videographer didn't think much imagining disappointment of your entertainment reduced, than avoiding his/her life ending.

Thank you

That was definitely a rigging issue, but why was the load held suspended for so long? May as well turn everything off and secure the area.

2:52 it starts
You can see cable snapping. Who ever approved under rated cables is responsible!
Rigger ropesman
“Now watch as we load this priceless………………scrap iron……”
That wasn't a crane accident...it was a rigging accident. Probably used worn out or inferior rigging!
That Rigging was Friggin wrong....
I agree with you.
What do you think was the problem? Specifically
The use of small cable instead of large chain. The weak part of cable is in the crimped ends. Proper chain with bolt on Clevis ends would have held.

Looking at the "rigging" I can't say I'm really surprised. Was this the accident that killed a guy?
No, no injuries. www.osha.gov/pls/imis/accidentsearch.accident_detail?id=200676286
No.
Laura Bush killed a guy

Rigging engineer did not add enough helium balloons. Everyone makes mistakes.
There was a crane accident here that killed a friend of my dad back in 2002. Does anyone have any info on that?
When you say HERE . where is HERE? IN THE UNITED STATES?

Those chains from Harbor Freight never hold !

*Hello Mr. George, he no good operator!*
They are using straps instead pf chains.
The camera man had one job to do!
You had one job. Why do so many people drop the camera when the action starts??
I think the instant something like this happens you get a fright
Don't understand why they lifted load too much high.
The crane on the left turned slight, the weight was more based on the left hand side because it turned slightly to the ship. The rigging also could had more error to count for, maybe 200tons freedom of error could had prevented this.

What about the rigger ropesman checking everything
I will never ever understand why someone with a camera violently shakes it when something interesting is happening.
Scared the crap out him maybe ? I knew it was coming and I flinched
Fighting experience then one freeze or drop camera 🤳📸
Poor rigging. That sidnt happen in the US. WE DONT PLAY THAT!
The cameraman has Parkinsons
NOTHING suports the lateral load in long side, eventually fails.
Cameraman had ONE job….
Get a camera stand……….
Hard to get a clear video if you are suffering from Parkinson's Disease.
@coloradomountainman8659 Hard to write good comments when you're a douchebag...
In the best part we can watch nothing...
Stay calm and jeep the camera steady. How am I supposed to watch the thing fall and break? Doofus.
it's sad but it happened suddenly and it's reasonable to panic and not prioritize the video
Crane operators
How long do you want to let it dangle in the air?
Job supervisor
Yes
He stands too close to film and is not prepared for anything and ruins the filming.
And this my friends is why you never walk under a working load.
Kevlars need softeners , always .
Well thats destroyed
That'll buff right out.
Camera person should seek treatment against Parkinsons
Safety third 😊😊😊
Hey the balloons made it 😜
every one was ok
The strap set up didn’t seem right
Looked like the spreader bar buckled
Yea don't watch... failure is in the last 10 seconds... an camera man somehow misses it allllll.. lol
they use rubberband
It's a hard thing to lift and they tried to decrease the wire tension by having veritcle lines from the bar...but the problem is that they still had huge tension on the angled lines coming from the crane to the bar...They were probably trying to keep the angle within 60 degrees but when a wire is under that much tension it better be a perfect wire or it's gonna fail catastrophically....and what was that idiot doing standing under the load like that?

It looks like they kept the load in the air for too long until the cables snapped.
But barring that even if kept 2 hours in air
Goes about the rigger ropesman checking the quality and condition of what ever they used
There gonna need a new Jose
SIMOPS! Always 50/50 chance of failure with heavy lifts.
Waste of time watching
Oooppppssss. Angel of the dangel =
Damit camera man
Too bad the cameraman can’t keep camera steady
Yeah, non union workers never have accidents....🤣🤣🤣
Low bidder crane operator. There goes his insurance.
It looked like Seaboard cargo being loaded by a pair of Seaboard cranes?
They were moving the lower half of a dock crane, the slings were cradled around the outriggers that had square edges that cut the slings.
Creeper
Exactly what you'd expect from under worked, over paid, union employees.
How do you know they are Union workers. They don’t even speak English so I doubt if this port is even in the USA
My jealousy detector just pegged high on this one 😂
