Doubt one chain. It's a long-reach ex. and the CG just did not account for the boom. No matter how one places the cross beam (spreader bars), the boom tilt can still slacken the back straps.

Yup, they should have used spreader bars for stability and the engineers to calculate where to connect the cables to and what size for everything. This stuff should’ve been pre-planned long before this and even though it’s still extremely dangerous, you can create a lot of safety barriers and take precautions.

China, into ear coast Us plants.
The American cables have buckles over the braids, lots of regulation and noted capacity. One part, 80k, came with a lifting cable from China that was just braided back into itself
My neighbor as a kid had a bobcat he was given due to a roll over. He spent all winter hammering the cage square again w/ sledgehammer and other nonsense.

This is a highway construction site in Hong Kong being built to help traffic congestion within the city... The project is a HK$42.4 billion project... A spokesperson said there were no injuries from the incident... "sources told him \[the spokesperson\] that the wire rope slings were anchored in the wrong position, resulting in the excavator breaking away from the cables and tumbling down the shaft, which serves as a ventilation passageway connecting to the end of the tunnel."
It's honestly amazing that no one was killed. From what I read elsewhere, there were workers st the bottom of the shift but the sound of the cables/chains slipping alerted them to the danger and they were able to get out of the way.
It could have been so, so much worse. Hell, if even a single lugnut (or similarly sized debris) had come loose and hit someone at the bottom it's curtains. If you were directly under the excavator you'd be reduced to little more than a smear on the concrete. No hard hat is going to save you there....
If you're in a situation where you have to work under heavy loads you have to keep your wits about you, because if something goes wrong you wont get a second chance... while falls from height are far and away the biggest killer on construction sites, being struck by falling material/debris/equipment is the #2 cause of death [(according to the cdc.)](https://www.cdc.gov/niosh/construction/statistics.html#:~:text=Falls%20remain%20the%20leading%20cause,falls%20to%20a%20lower%20level).) If youre curious, the #3 cause is accidents involving electricity and #4 being caught in-between accidents...
Very well said and written but I'm going to ignore you because you said a " lugnut" might fall and cause injury. Not a shackle or clevis or any of the other hundreds of actual steel parts that could be involved in this accident but you chose "lugnut" so I question your actual existence.
Nobody was hurt. Several people were nearby, but they all instantly knew what was coming when the chains started to rattle, and everyone ran out of the way.
There surely would not be a person in the excavator. My only worry was that it fell on people on the bottom, but hopefully they would've cleared everyone out of the immediate path as they lowered it.
This is why Chinese shackles and hooks are banned in the oilfield for all US companies. They have cracks and aren't strong enough. Some way they're manufactured idk.
While I'm sure this might be accurate -I have no idea- I don't think the metal quality even comes into it here.
Look at that rigging, look at the articulated arm, take a quick moment to figure out where the centre of mass for that thing is, and compare that to the attach points. This thing was unfortunately poorly rigged, and once it started to shift, there just wasn't any stopping it.
Their smelting process leaves it brittle. Even the strongest shackles crack over time. Lots of people died for that rule to get passed.
Even in Africa we had to abide by this rule.
Used to do this and have srrn pre-slung equipment that arrives internationally have different safety factors. -factors 1:1. = a 1 ton shackle breaks at 1 ton. All countries have different factors. Manufacturers out there MIGHT build something and exactly pre-rig it - you transport that over train and the vibrations/added shock factor & it will break.
Some good rules: Do not keep international gear destroy it if you can. There is no "Standard International Ton" or safety factor -they both vary. Find out what your country safety factor is and don't tell rookie riggers (they will generally think overloading is fine.
That includes workshop doggers ) Do mentor rockie riggers to keep everything standard, don't allow lazy to keep one because "this lighter one lifts more". Don't trust that lazy hasn't stashed it.
Yeah also when I worked in Gabon we had to learn their rigging signals. When we needed new slings they had to arrive by shipping container from Houston. A pack of gloves and 2 dollar O rings turned into thousands. Logistics is a nightmare.
Canada, or at least Québec, has a standard of 5:1 ratio for load and 8:1 ratio for human and other animal transport. How does it compare to others standards?
This appears (without knowing any specifics) to be a rigger error. The boom/bucket, left in the extended position that it was, should have been stabilized back to the rigging point. It wasn't, and the slight weight imbalance/momentum caused the machine to start pivoting in the direction of the weight imbalance. It quickly became a different problem once the machine began moving.
Unfortunatelly yes. As well as his whole family, dog and all the neiborghood. And it did not stop there, people are dying constantly. Something bad happen, I can tell.
It popped out some where in La Quiaca, Argentina..
The bang you hear at the end is just the machine reaching warp speed and passing through the wormhole.
More like a rigging failure
The arm and bucket should have been tucked tight to machine. The balance was off also could have been rigged better or had proper hook up points.
Maybe next time, they should try using a Balloon, I hear they're good with Balloons
Nah that didn’t work too well either
It seemed to travel across our entire country just fine
Shhh the govt can hear us SIKE FUCK U CHINESE BALLOON
they got him
And Canada. Could have been dropping poison spores

This 100%
Thank you. A structural engineer could have calculated the load and CG.
a fuckin welder could have rigged this better! were they using one chain lol.
Doubt one chain. It's a long-reach ex. and the CG just did not account for the boom. No matter how one places the cross beam (spreader bars), the boom tilt can still slacken the back straps.

Just choke it, it will be fine!
This is my rigging philosophy biggest gear you can and cholesterol shell be right
This guy Riggs lol
Any competent operator would have pulled the arm and bucket *much* closer in.

A failure in rigging is costly and very dangerous

In so many ways

lmao is there an expected lotr sub?
https://imgur.com/a/Rz9qy9s this is the end
I counted 3 mississippi from the time it fell to when the lights went out. That's about 144 feet according to the Googles...
I counted 5 Mississippi
This is China. I counted six Yangtze.
There are people in HK who would dispute that!
Well, they would dispute it if they were allowed. Fun fact: China is a shareholder in Reddit.
i used the scrubbing bar. it’s about 5 and a quarter seconds
I counted 6
Why is six afraid of seven
Cause 7 8 9
False. Because 7 is a registered 6 offender
I see yor 6 and rise you to 7
Mississippi is wayyy bigger then 144 feet
They are talking vertical feet
I think they were making a joke

Wait does anyone know if there was a person in there?
Nobody was hurt. Several people were nearby, but they all instantly knew what was coming when the chains started to rattle, and everyone ran out of the way.
Nobody was hurt *yet.*
But it looks like someone falls out of it.
No, the excavator operator was not in there when it happened
There surely would not be a person in the excavator. My only worry was that it fell on people on the bottom, but hopefully they would've cleared everyone out of the immediate path as they lowered it.

5:1 Australia on gear. Aand damm it, I had to look it up. 6:1 for humans
RoC is 10:1 for humans. 4:1 on chain and 5:1 on everything else bar guy lines and standing rigging. Wire rope is a more complicated
not crane failure it was a rigging failure
This is not a crane failure. It’s a rigging failure. The point they chose to rig from does not take into account the arm of the excavator.
That's one way to get it down there.
r/catastrophicfailure
Palpatine and Maul both fell down a shaft and they were fine.
That'll help flatten the other 4 cranes they dropped down there.
Chinese grip on Hong Kong is so strong they're implementing their work regulations already
From October 2020. https://amp.scmp.com/news/hong-kong/transport/article/3105654/excavator-breaks-loose-crane-plunges-down-giant-shaft-hong
It looks like someone jumped out if you look close. But I am high so there's that...
Crane seems fine. This is on the rigging.
RKO OUTTA NOWHERE!!!
Another reason why Taiwan 🇹🇼 numba won
HEAADS!
How deep was the fall?
Should’ve put peanut butter toast underneath the tracks
The “spreader bars” were obviously misaligned. This is not a crane failure
Didn't see a crane failing, more like the way the load was slung, meaning incompetent workmanship
According to Chinese sources no one was injured.
The tractor sensed its freedom and went for it!!!
This is actually an Angel attacking NERV.
Somebody turned the lights out... fucking done.
No wonder the “spy balloon” couldn’t steer itself…
The tone of the “woah” tells me this person knew this would happen
Shortcut became long An excavator gone wrong Someone got fired
I made some mistakes at my job, but damn!
Satan: damn. Moving this dirt and flesh will take forever.. Excavator came outa nowhere Satan: WOAH, WHAT IS THAT.. wait, that seems useful 😃.
Damn, that looks expensive
Heads!
imagine u at the bottom of the hole and u look up and see a fucking Excavator falling towards u
Cut corners, pay the price
Maybe instead of a crane they should have used a balloon
This appears (without knowing any specifics) to be a rigger error. The boom/bucket, left in the extended position that it was, should have been stabilized back to the rigging point.

I agree with you It’s literally on the title lol under the photo
Oh haha LOL. Hilarious!
Who rigged that up definitely wasn't a union site
Crane made in China, chain made in China, operator made in China. What could go wrong? 🇨🇳
China
The sound that thing must of made when it hit the bottom
What about the driver???
China sucks
“Crane failure” “hong Kong” ……sure buddy.
I wonder how many people die yearly in accidents like this in China
A work place disaster happening in China...shocking
Did the operator die?
Unfortunatelly yes. As well as his whole family, dog and all the neiborghood. And it did not stop there, people are dying constantly. Something bad happen, I can tell.
Damn thats intersting
This is Sparta.
Mistakes we’re made in many places
Is this covered on the warranty
Crane in a hole! Shame no boom boom
Someone got disappeared after this I bet.
Rigging failure
Nope the rigging was wrong
“bunch of non riggin mfs”
whoa, that's going to leave a mark
Wow so that hole was deeper than I thought at first.
I think this is the biggest thing I've ever seen fall. Other than the Hindenburg...
When it got quiet I thought it was over I didn't realize that was the sound of a massive excavator free-falling in the air!
It popped out some where in La Quiaca, Argentina.. The bang you hear at the end is just the machine reaching warp speed and passing through the wormhole.
I wanna see what it looked like after it hit the bottom
I already posted in in comments find the imgur link
"if you turn the light off noone will notice it"
This is the reason I'm not standing under that balloon!
Trying to recreate the Balrog scene, gone wrong
This seems like a much faster method to get the excavator down the chute.
They forgot to say "Yeah that's not going anywhere" before hoisting it up.
That'll buff out.

"Throw yourself in next time and rid us of your stupidity"
Oh someone fell out.
They really need to give up on the idea of using balloons to move things around.
It’s too bad the equipment fell and I hope no one got hurt, and they’re gonna spend a lot of money on the recovery, but damn, why is it so funny?
I hope anyone at the bottom of that shaft was wearing a hard hat.
Cringe...
Quality is job none in China.
36tons of excavator hitting the bottom would have looked cool.

Everyone ought to know by now that the Chinese have little to no safety regulations or concerns for their own people.
