It's no biggie, we'll just leave it for night shift.
swear to god, you speak the truth!
i work night shift and can confirm!
@@yaboiii64 Me too brother!
I work at a power plant and work night shift. So true
@@cCH3artlessCc All of the bosses and lookey loos are gone then you can get the real work done on night shift. How can you spot a Plant Operator? When his feet hit the desk before his ass hits the chair, that's an Operator.
After an incident like this there’s literally nothing to do but go to the bar.
Shout OOPSIE first
And thats where Tony comes in...
..."Ok Tony. Here's how you make big points with the boss on your first day. Stand here, and when he shows up, put your hand on this lever and yell "OH FUCK"".
@@siggyretburns7523 Its always Tony's fault

that F***ing New Guy Tony did it👉🚶
you cant.....everyone is pissing in bottles.
Im sure somewhere there is a safety man saying "see thats why we wear steel toe boots"
Why wouldn’t there be, steel toe boots can easily stop 75 tons from crushing your toes
Hahahahahahaha
Don't forget the hard hat.
And safety glasses
Steel toe boots cut my toes off my right foot.
That's the sound of a job opening.
Really? You wanna start your new job by getting that thing out?
Or a business going under.
_or nam flashbacks_
@@DesertEagleV A crow bar and a little paint. That'll buff right out.
I CAN HEAR MY OLD BOSS SAY "SHIP IT" !.......
Now, that is funny. I've heard that a time or two...
Lol it's the same thing all across the world 😂
@@adrian9098 hilarious
Its still within specs...ship it.
like opening the hood of my car and find some tools from the mechanic in top of the engine.it got me thinking what other things he could forgot.
I was the rigger as an apprentice of some 20ft hat channel being hoisted to the roof on a university when a strap failed sending the load crashing into the roof just feet away from killing my foreman. The strap wasnt cut or rigged wrong, come to find out the strap was just old and came from the shop. Lesson learned was to always inspect the straps and make sure no red threads are visible and that the straps arent weathered. Life long lesson learned in a fraction of a second. Inspect your straps, inspect the load, and most importantly never stand under a load.
I've been doing heavy lifts for years, I have no fear when it comes to over head cranes. As long as the load is on the ground, no rigging attached, the crane is off and I'm not in the shop.
That's one that you can't blame on the apprentice.
Yup, pretty sure I saw him up there on a lift last week, wasn't he supposed to be just blowing the dust off the bridge? What was he doing up there with a crescent wrench in his hands....
Watch me!
And he’s usually just standing there slack jawed anyways.
Is that a harbor freight label on that crane?
🤣😂😅
Central Machinery 😆
I wonder how many people don’t get that joke and how many people like me think it’s brilliant
Hey I like harbour freight 😂 😉
priceless
That is why most riggers wear brown pants.
With incidents like this, they become brown!
LMAO
Half of them wear them on their knees, oh! wait, rigges, my bad!
in my world , we called the brown pants and paint , " pre emptive brownness" ha! i shit myself just wTching this vid when a dufus walks under / next to lift. duuuumb . not b4ave stupid. glad no one got hurt.

My first thought when seeing that fall was " Damn, thats gonna be expensive".
Eh, it'll buff out . . .
Thank you Captain Obvious!
That's what I thought.
each one of the fins on something like this is around $15,000 USD
Insurance will cover ....
I'm not an expert in overhead crane technology, but: after extensively reviewing the footage (including a frame-by-frame analysis, and extensive processing to enhance the light and contrast), it is my professional opinion that someone definitely got fired for this.
Maybe he had to work it off.
i like the subtle humor of this reply
I came to the exact same conclusion! Especially when the whole thing makes that BOOM sound.... Don't believe that it should make that sound! Seriously glad that no one seems to be injured. Especially the guy that walks directly under a live lift!
Maybe more than one got fired ! Operator and maintenance I would imagine!
Why would they get fired? The crane failed.
This takes 'bearing crush' to a whole new level.
Imagine being the one who made the awkward phone call to someone after that.
"It's a little bit a tight fit, just to be on the save side let the insurance evaluate it and check the tolerances."
@@HobbyOrganist In this case, there is no repair. They have to make new rotor. That, together with additional plant idling for several weeks at best, will cost north of 5-6M. Hopefully, will be payed by insurance, but still the contractor gonna feel it next time he will be buying insurance, premiums rise after incidents like that. And, of course, heads gonna roll.
You don't make.a.phone call, you text them a picture of the carnage.
@@stlyns ... and then switch your phone off! 😃
"Hey Sam, remember that turbine that you helped finish up right before you went on vacation?
Well, it should go a lot quicker the second time around"
🤣🤣🤣🤣🤣
"Hey boss should i do a crane inspection before starting work?"...
"NO, that's going to add another hour and production wants the machine now." ....
"Ok, I'll just sign off the check sheet."
That happens more often than we know.
Than after the fact, boss - "why didn't you follow our company safety training? Every employee watched the safety video and took the test and signed off on that training. No excuse from you, We have to let you go"
Bruh I’m taking an aviation maintenance class and there’s an entire PowerPoint that the faa has designed to make sure people don’t sign work they don’t do. At that point it’s just ignorance
@@Mongoliantreecow Good luck in the class. Safety is a religion with the manufacturer's documentation as its bible. Do everything by that book, and you won't go wrong.
@@Mongoliantreecow actually at that point, all ignorance is dispelled. Moving forward, any such situations would be pure dumbness.
I echo what Joseph said. If there are situations with ambiguity or variance (or anything that's not straightforward by the book,) talk it around with the team & get a consensus with the necessary buy-in. If it's important enough for a boss to justify "one-off" behavior, then it's important enough for the boss to document.
If that changes the boss' mind, you know you did the right thing.
If that makes the boss say you'll get fired, you know you did the right thing.
If the boss says, "Yeah, we should document the variation," you know you did the right thing.
Wonder what the first thought the boss had, when his coffee cup on his desk jumped.... "shit...that didn't sound right...."
Lol
Best comment.
This is where you grab your car keys, walk out the door and never come back
This is _exactly_ what happened in a nuke power station a few years ago. They were lifting a steam turbine rotor, just like this one, and it dropped onto the concrete floor (I even have a photocopy of a photo). The crane op never came back.
Welp I guess that's the end of that career
Looks to me like a mechanical failure of the crane, not an operator error. Was the failed part subject to routine maintenance or required to be inspected? If so, that is the person / people that would be polishing up the resume.
@@FineEngineer what’s a typical cause of a failure like this one?
I worked at a plant that builds transformers up to 700kv range. The biggest one we were rated to build is 400 tons. We had a core assembly of a transformer drop. 120 tons. Punched through 2 inch steel plating on the floor and then put another 4 foot wide by 6 inch deep hole in the concrete. The whole assembly fell on its side. This shit ain't no joke. We got extremely lucky that day. I have seen some very stupid people do some very stupid things with an overhead crane.
The turbine blades held the lifting device when it fell and nobody was near the center where the pulley block landed, very lucky, because there are plenty of ways to get crushed without being directly under the load.
Those vanes are tough, i expected way more damage to them.
about when you typed this a tree fell on me and i admit,it was trying to use me for a nail. it got me like never before. i am still laying from it. all i did was walk under it. i feel the strategic air injection is killing all the trees on our street. they are breaking in large large chunks at any time. never seen this b4 in life
1 minute earlier there was a guy standing right there
Turbine vanes eh?
@@JonSnow-bc6ro Could have been a lot longer than a minute as there was an edit in the video just before it dropped. But still, had it happened when he was there he most likely would be dead or severely injured.
"Llllliike a glove"
Many years ago, possibly the 1960s, my uncle was a police officer in Cleveland and was working a part time job at one of the steel mills. Some how a load was dropped and crushed his legs. I seem to recall that it took something like seven operations and over a year before he could walk again. He did recover and did get back on the police department.
surprised he can walk...takes OXY's like M&M's... and they are abt as useful as M&M's?
@@gmcinnis6304 That was at a time before OXYs were even a thing. I won't say that he was like he was before the accident, but he healed and was functional, capable of doing his job. He worked something like another 20 years after that and eventually retired.
At my old place my neighbor got his hips smashed by his own tractor. He had removed the rollover-bar so it would fit into his garage and ironically that's probably what would have saved him.
Just a split second before it dropped, I heard the winch motor or gearbox whine.
I heard that too. It sounded to me like the brake was no holding and you could hear the gear train whining as the load descended. The old millwright saying “beat to fit and paint to match” comes to mind.
That broken coupling was most likely attached to the brake
@Ci' Absalon the sound I am describing starts at about 1:50 and happens before the load falls. The crane operator is intermittently energizing the electric motor to slow the descent. If the brake truly fails, I am not sure if the gear train could even support the hook. So I am not sure if the cable broke at all. The load in this video is the rotor for a gas turbine.
@Ci' Absalon No, and why would they brake when there was no load on them once the coupling failed?
@Ci' Absalon if the ropes broke one of them would be on the ground. Once the block stops the ropes stopped. It looks like the brake failed. Without the brake a load will just drag rope out and won’t stop until the block hits the ground. The popping was likely from the rails. The cranes in our shop will creak and pop when going over certain spots on the rails. Overhead cranes make all kinds of odd sounds.
No amount of flex seal can fix that....
Ya gotta step up to gorilla glue !
Nice job of centering it

That's a lotta damage!
The guy at 1:55 was one lucky dude!!! standing under a 75 ton load is nuts..
Relax. Can't you see he was wearing a safety helmet?
Standing under a five pound load is nuts. Standing under a 75 ton load is well beyond your pay grade!
He is lucky to be sure, if it got him there wouldn't be anything more than a hard hat pancaked down onto his safety boots, but the safety supervisor would say "see? Hard hats and boots work..."
its a sad day when people still need to be told to not stand under stuff like this.
Yeah, that idiot in blue nearly finished as bearing lubricant.
@@istra70 calm down dude we are just humans
@@revisedcandy4295 Yeah, I know. Many times I would think - who cares - let natural selection do it's job .... But it creates problems for others ....
Just make sure they're wearing their helmets and safety glasses.
Yup... Yup... yup (3 WISE MEN... in the alley.. drinking and THINKING about.. SAFETY!!!! IS JOB 1!!!!!!)
This accident couldn't have happened at a more perfect time. But THAT DUDE, good god he is lucky to be alive.
Note to maintanence boss. "When getting ready to lift million dollar machinery have the crane inspected for any issues"
Probably wouldn’t have caught this one but you would be covering your backside.
No safety brake
Due to political correctness I can’t say what I would like to say.
@Craig Tucker it showed the broken coupling.
@Craig Tucker the crane should not break a coupling and then just fall.
I worked in a place that handled heavy steel coils. Whenever they started lifting I would get as far from them as I could.
Cable whip is still dangerous at distance
Smart reliable method to stay alive and one piece ! I would do the same no matter what !
Call me a pussy for it any day of the week...but you aren't gonna find me over a suspended load..no sir...👍🏼...give me chills watching some guys do it like nothing...
@@gilbertolopez5257 You are not a pussy , you are intelligent enough to not gamble with your own life . Nothing wrong with that , personally i believe those who do that have a deathwish or they are doing it completely lost in their thoughts ...I saw one too many accidents in a dock at a port once and it was more than enough to convince me NEVER i would do such thing ...let's say it didn't look nice , too much "ketchup" for my taste !
Yeah, I always told apprentices, if someone tells you to do something you think is unsafe or makes you uncomfortable... refuse to do it, you have that right and if it comes down to it, better your job than your life.
Yes, it happened to me as well. I am always fascinated and annoyed by people who are casually walking around the heavy loads. Nobody knows what is happening with nylon slings, a crane shaft or entire crane structure. You have to ALWAYS keep distance from lifting objects!!!
That Crane Companies motto: "We stand behind our cranes...not under them"
Hahahah hahahah, no shit! Good one
They bought a 100 T crane, however it was shipped a with 50 T gearbox.
is it true or are you just trolling?
cheapest pot cast iron in the world on that part they showed... next time BILLET OUT OF SOLID STEEL MACHINED ... x rayed for imperfections. costs a little more... but not as much as the settlemment will cost for this $$$$$ gas turbine engine fan/bearings/work...

And failure occurred right after that guy walked through there.My dad is a retired overhead crane operator.I don’t know how many times he’d come home telling how someone walked under the load.
I worked in the Quincy Mass. General Dynamics shipyard in the mid 60's and If you work with cranes and tell me you never walked under a load, I call you a liar.
And that is why you have to over-engineer, I don't care what anybody says.

"Ohhhhh boyyyyyy, here we go again"
Oh man. That was a VERY expensive fail. Many millions down the drain I'm sure. Those things have to be balanced to insane levels. The machining cost alone must be huge.
That sounds expensive.
Looks expensive too
It is, I think it was 5 million in damages
That rotor is well over 30 million. I was on a job where we messed up a rotor dur to poor supervision and it had to be unstacked and repaired. It was a smaller unit but we were told it around 30 million to replace
Hello State Farm?
@David Bryant Not JUST the rotor though, the casting it was so rudely dropped on was also ruined!
Ouch. That was one hell of an expensive coupling failure.
that coupling looked like it suffered a sudden total failure, it did not appear as if it was a fatigue break
One more GE design gas turbine bites the dust. That rotor, probably a Frame 7, is well up in the 6 figure range, low 6 figure if it's repairable. Then there is bearing housing damage and maybe even turbine case damage. including blading since clearances are measured in thousandths.
Lots of new openings at the job site tho! Always a positive 🤣🤣
I am glad that no one was injured, but I have to say that is one expensive drop!
It’s called “Preventive Maintenance” for a reason.

And some sh!t tickets! ( )) 😆
The same thing happened to me moving a Large Transformer at a local steel mill in Pa. Brakes left go. No one got hurt and the transformer came down and sat on the floor. The only thing was, I just had the crane inspectors and repairmen just look everything over. You never know. I was watching the one worker walk almost underneath that lift. WOW ! Very Lucky man.
Things can break/go wrong at any time.
As for the guy walking under the load...very stupid guy.
433 Ironworker here. I know that brake sound, I've saved several lives in my career from telling them to take cover. Brakes gave out. Bunch of dumb shits under that load also.
I'm not a 433 ironworker here!! But I did stay at the Holiday Inn last night and I totally agree!!
Glad they were wearing safety helmets
Those guys were in great danger of damaging their shiny white helmets
Yes , good point, hahahah
I work in the same field and I feel desperate for them.
To replace a turbine rotor maybe it could take 1 year.
A super expensive damage.
i guess at least 5 people instantly lost their jobs...
@@patcowley6378 maybe not directly them.. but it's for sure that somebody got fired.
The problem is that the power plant can't work until the turbine rotor is replaced.
@@riccardorampini9266 And possibly replacing part or all of the pedestal.
@@perryfarmer3280 that's for sure.
But what I dont understand is why there was installed that coupling joint crane... It's a very cheap type and not reliable for this kind of installation.
@@riccardorampini9266 I never saw turbine rotors installed coupled. This places stress at the coupling unless supported on both sides. This whole lift starting with a worker filmed without safety glasses looks like a disaster. The worker near the coupling when it finally dropped was lucky but oddly didn't seemed especially concerned.
This accident probably damage the pedestal, the chest, the bearings, the blades and the shaft. Probably a simple bora scope will reveal damage when looking for brittle bore shaft issues. An accident like this in an older plant have caused early plant retirements.
During most of the lift there were noises that did not sound good. This may have been avoided by returning the unit back to the cradle.
"Hi.... is this Jake from State Farm?"
"What are you wearing Jake?" 🙄
Damn, that brings me flashbacks of when I was working under a Cat D7G Crawler Dozer that was sitting on big wooded blocks with their tracks off. Cause 5 minutes later after I when to launch that Cat D7G Crawler Dozer fell off the blocks. I was very damn lucky that day. I never worked under a dozer like that or any other again I didn't care how much they pay me. I worked there for 3 months after that and found a better job cause they didn't care about safety. A friend of mine got his arm torn off by a steel beam fell on his arm.
and the companies shyster lawyers will DO EVERYTHING TO DISAVOW ANY WRONG DONIG!!! EVERYTHING.. didnt happen... he was fired 30 mins ago, i want him arrested for trespassing
Well that's one way to seat the bearings in a rotating assembly.
New meaning to tilting pad bearings.
I think that the place down the street is hiring
"Shit! Oh well.
Lets go have another beer guys!! Let swing shift deal with it."
The Springfield nuclear power plant. Ask for Homer.
Used to work at a steel stockholder, we lifted anything upto about 20 tonnes with our cranes, you’d NEVER see me anywhere under a load, we only wore hard hats cause we’d walk into the racking and crack our heads on it. Saw chains fail (that’d been regularly checked and tested), saw cranes fail (likewise, tested and serviced), and had humans controlling the cranes, we were good at what we did but one wrong button press and you could cause all sorts of damage.
As a side note I delivered steel into the Airbus wing factory near Chester and they have entire wings moving about on remote cranes, that was a sight to behold 😀
“Hey boss, you’re not going to believe this, but the funniest thing just happened”...
Low elevation gravity pressure bearing seating method.
😂👍
lmao
Thats the call you dont want to make.
The guy walking up the stairs, who just passed beneath the turbine, ran off to change his pants!
May have a bit of shake to her but they can sort that during commissioning. It was fine when it left the plant!
Those turbines are insanely expensive even when you don't drop them...
Wait, you want me to pee in what cup?
Yep! Lol.
"Hey Boss"
Yeah???
"You know you cancelled Saturday overtime for crane inspection and PM due to budget costs"
"Yeah"
"Well, looks like we are now working Saturday and Sunday, unfortunately you have just became the next budget cut"
And that is why you have a double brake system on your hoists. Even if the motor blows or or coupling fails, as long as the gearbox does not explode the load will not fall.
He protecc
He attacc
But most importantly, he gives the crane cable slacc
Hahahahaa
When your overhead lifting components say ( made in china)
Underrated comment. SO True!
Racist bigots
@@michaelangelo6378 I am someone who buys tools for a living including rigging equipment (including wire and chain hoists.). For the majority of products marked “made in china” I would recommend you stay away from if its to be used for any life safety situation. I had a contractor I hired show up with two brand new/ still in the box made in china wire rope hoists. First they could not even lift their rated and then were falling apart on the first day. It put the job back 3 days for them to get the right equipment in and this put the project behind and cost me money. From my experiences you are asking for issues since the products are made to a lesser standard.
It was in Russia
@@michaelangelo6378 Please tell me what race has to do with it? China historically has been know for producing junk tools. Since you automatically went to the race card, maybe you should look in the mirror?
"Well....this is another fine mess you've gotten us into"
Lol
Well at least turbines are really easy to build, very cheap, and can be redone very rapidly. It would have been a real bummer if this was something that is difficult to make, very costly, or with a long lead time required.
"That's not as bad as I thought.... Oh yeah, that'll buff right out."
That's going to cost them plenty! Glad no one was under it!
A little JB weld and that will buff right out!
Exactly! Also, a shot of WD40!
And duct tape
Just call it the "new and improved" version 2.0 and charge twice as much!
Booger snot, save the buck.
That turbine compressor is toast...bet that wasn’t cheap.
Never stand under a lift, common friggin sense. Although I’ve been working around lifts for 20+ years and have done it many times years ago, not anymore though. The updated safety regulations, for those of us who were around before they were widely implemented can be irritating, but they’re usually in place because someone got hurt.
"Break time!"
"When we clocked out, it was fine. They did it!" 👉 "We found it like this when we clocked in, They did it."👈
This is why these cranes are supposed to be periodically inspected, and those of this capacity should have regular NDT inspections.......im a retired crane tech, and in my area, nothing like this has ever occurred, most accidents are overloading, and it appears this may have been possible, the use of crane dynamometers is important to insure safety...
Somebody just pencil whipped the crane inspection......🤣😂
Despite tremendous effort, nobody died.
Before performing this important operation with the crane, it is necessary to do a dynamic test (the nominal load + 10%) to be sure of the crane, and preferably this type of crane must be equipped with a safety brake or drum brake.
brake failed !
preferably to have in addition to the service brake, a cable drum safety brake which reacts after an overspeed measure on the lift, and stops the fall.
It would be nice if they identified what part of the crane failed. The video shows what looks like broken cast or forged metal part, possibly some sort of coupling.
Especially on a worksite: assume that everything is going to kill and that everyone is using the equipment wrong. The amount of times I've seen people walking under loads is ridiculous. One of the most common reason for dying at work is having something fall over you.
That's the break-in procedure.
"Break in procedure" ,... that is a good one.
I mean they broke it and it's in...
Heavy assembly group leader Bliss-Salem use to do 100-ton lifts all the time, the heaviest lift I observed was 500 tons in Cleveland as Field service rep for Alliance Machine.
Insurance guys first question: did everyone have their hard hat and safety glasses on ?
I cant even imagine how much that cost to replace. You cant use it once those fins are bent
4 year waiting list for G.E.
Why not it might make a bit of noise but it should still work.
If it were a coal fired plant, with so many of them shutting down perhaps it was never replaced, the utility just shut the place down and had electricity from somewhere else. They might have just left the turbine and crane there and abandoned them.
@@MrNeptunebob hell I just assumed it was a nuclear plant since they're changing out turbines.
@@moderndaydrifter4672 they have to be perfectly balanced. You dont want that thing spinning a bearing and coming loose lol
That’s not 75t orange slings are rated at 10 metric tonnes in that configuration 20 metric tonnes.
wrong, and the slings are not what broke.
@@jerryw6699 oh der, my point was that this is not a 75 ton load look up the rating of orange slings 10000kg in basket configeration 20000kg. both sides 40000 kg I am a rigger by trade
OSHA:what did it cost you
Supervisor:everything
OSHA:was it worth it?
Points of interest - 1) If you need to be told "Never Stand Under a Lift", maybe you're in the wrong line of work. 2) That can probably be buffed out.
Looks like the block wasn't heavy enough to handle the load, at US Steel our 100 ton block and hooks were massive, the one here looks like a 15-20 ton block. Just don't understand why some people just feel the need to walk beneath a live lift, like that guy did in the video!?!
@Ric Fan for sure! our safety man would have taken this dude outside and gave him a what for! plus a few days off without pay!
Hey! GE! This doesn’t seem to be spinning right!
The anticipation in this video is killer.
Not being a Crain guy, Can someone breakdown exactly what failed and some possible reasons why. I was a Submariner for 26 years and was involved in weapons handling. On the older SSBNs we would use two electric hoist to raise and lower each torpedo. On one of my boats, one of the cranes was a Coffing hoist. Commonly referred to as a "Coffin" hoist. It never had any issues but the NAME was scary. You can bet your ASS that "NEVER get under a suspended load" was enforced and respected. Especially when we were at sea and the ship had some pitch and roll. It would get your attention and sometimes quickly.. We never had a hoist issue but a weapon did get loose once while we were moving it horizontally. Someone whipped his jacket under the rollers and stopped it from rolling backwards into the bulkhead. He literally saved the day!
my dad used to repair turbine engines. That shaft with the blade disks, blades mounted and balanced was about $20 million.
@UNABOMBER MANIFESTO Some major manufacturing companies will use a jet turbine engine to power an onsite generator for whatever purpose. Without knowing the specifics of the facility in the video, that turbine core they just busted up could simply be tied into a steam system and spin a generator.
My father spent 30+ years working at the jet shop at Dallas Love Field Airport breaking down exhaust casings for Pratt&Whitney, Westinghouse, and GE engines used on commercial aircraft. He did get sent out to San Francisco years ago (early 80s) to repair a jet engine used for electrical power generation for some company.
At 3:20 you have a cast iron Lovejoy coupling. What kind of education did the engineer have that designed that connection. It should of been a five piece mill coupling made from steel. Then again who was the genius that accepted this type of crane in this work environment. Luckily no one got killed, but it cost some big bucks to fix it.
I was thinking the same thing cast crap .. Should have been solid steel milled .
This is some former Soviet block country, the equipment was most likely made to the standards set by a committee of clueless political committee. Soviet navy ships used to bristle with weapons. I was told it was because they only expected half of them to actually work.
@@michaelmurdock6560 This happened in the Netherlands, home of some of the biggest engineering firms on the planet, it just goes to show that anyone can fuck up - even in the land of Mammoet.
I THINK THE SHARP CLICKS WERE THE SPOKES OF THE LOVEJOY JAWS BREAKING!!
ONE BY ONE!!
Pot metal.
Failure of shaft coupling. Usually there is redundancy via having the brake unit in line. Unfortunately there are still cranes out there with this set up...
I have seen complete Booms collapse & fall from Shipyard Gantry Cranes before. Thank God nobody got hurt or ended up dead. When you are an operator or rigger your life is on the front lines every day. Your Very worst mistake would be to take that for granted.💙
Just put it in the $5 bin at Walmart. I’m sure Spirit airlines will pick it up for a cheap engine fix. 🙄🙄
@i laugh at you 19 others say you need to loosen up. PS- Your opinion doesn't matter to me. Always one person like you everywhere.
This isn’t an engine. The is a steam turbine at a power generation plant.
@@Hesthegreatest1 yes, it am aware. It's SARCASM.
I have to admit your comment is funny ,Even as former Spirit Pilot before Ned Homfeld Sold the company and it turned to the airline it is today :( I Left when Ned left. before that Spirit was Great place low fairs, no frills, And real customer care.
@@TheFalconJetDriver I'm just a sarcastic, retired due to Injuries in the line of duty, Paramedic/Firefighter and private pilot. No harm meant to your career. I lived with a Captain for American, so heard lots of trash talk. Right up to the point that I found him in our bed with his lead FA on the PHX to EWR run.
Hoist brake failure or some engineer didn't have the total load weight calculated for the max lifting capacity of that 20 ton block.
gearbox shattered
@@jasinere35 Looks (to me) like a flexible coupling. Anti vibration or shaft alignment type. The gear tooth profile bits seem to be a resilient compound ring component, there are some bits of it in the background of the shot.
What looks a bit out of order is the yellow paint that has run into the component, possibly indicating that a "nice bright yellow machinery must be safe" policy is in operation.
Incredible how humans rush to conclusions and wanting to assign blame without having all the facts of the case in question.
@Saber Fox how do you know how much the turbine weighs? How many heavy lifts have you actually done?
@Saber Fox Did this same crane pull the rotor initially?
Back in the 1990s when I delivered a truckload of I-beams to a jobsite in Denver the crane lost a half-dozen 48-foot beams at-once when one of the straps broke. They fell from probably 40 feet in the air.
Now that we have the short block assembly complete we can move on to installing the head
