Overhead Crane Failure - Drops 75 Tons!

[@fancyketchup9071]

I was an overhead crane operator in a steel mill. My first day on the job they told me, "Once it's in the air, you own it." I never forgot that.

[@b.atwater3904]

Fancy Ketchup Excellent advice. Listen to the machine and keep your wits sharp! Too bad these simple, common sense skills are fading away with each new generation.

[@b.atwater3904]

Fancy Ketchup I get what you mean by "Owning it", it just means that it's a load you are lifting and have control over, not literally owning it , as in paying for it. What broke? A shaft in the pulley block, or a cable? The damage is all fixable and no one died..

[@msmith2603]

It's not even the cranes fault or anything at 2:48 he shows a label which states: "Werklast: 60000kg" literally translating into "operating load: 60000 kg" aka 60 tons. And as you may have guessed, putting 75 tons on a crane that's only supposed to lift 60 tons is NOT A GOOD IDEA.

[@triton115]

NKN1396 60,000 kg = 66.1 tons to be exact.

[@inthefade]

Tobias Heck Isn't it spelled tonnes when it is metric?

[@thekaiser4333]

Here in Europe, we do not use your outdated colonial nonsense units. 1000KG = 1 ton.

[@willpugh-calotte2199]

In English-speaking countries such as mine, which previously used the Imperial system of weights and measures, but has since converted to metric, we use "ton" to refer to the old Imperial weight of 2240 pounds, and "tonne" to refer to the metric weight of 1000 kilograms. You and we just have different assumptions about the default meaning of "ton".

Union Millwright, that rotor almost certainly destroyed the turbine case, estimated loss 100 million USD by time labor is figured in. That is about the original purchase construction cost here.

[@howmuchbsisthis]

this is a few years old now but for those of you that are just seeing this what caused the failure was the cable brake, well it broke the overhead crane had just not long before passed it's safety inspection and as you can see it was handling the load quite well it was only when the operator started to lower with short jerks that then then cable brake decided it had had enough hope this helps with understanding cheers

[@rodneybolduc6416]

The crane hoist brake was out of adjustment. The hoist should stop and hold the load almost instantly. In this video you can see & hear the load drifting, the brake drum slipping through the shoes... THATS NOT A GOOD SOUND PEOPLE..its overheating the brake drum to destruction. Im an overhead crane mechanic and Im blown away with how many crane operators I talk to dont know the dangers of runiing a crane that needs a hoist adjustment. All the Supervisors, maintenance crew and the crane operator him self in this video are all at fault here, A simple hoist brake adjustment could have stopped this disaster.

[@duanedean3256]

[@essentialjudge5430]

broken Lovejoy coupler.

[@gkess7106]

Brakes worked better than the casting holding up the (over) load. Casting failed, not the brakes. The rhythmic bumping of the brakes allowed the cables to take up slack when ‘bounced’ up and down each time the lowering motion was stopped. This flexing up and down eventually allowed the force downward to GREATLY exceed the design strength of the structure. The effective weight may have been more than double the 60 ton limit after each stop. If the operator RHYTHMICALLY stopped the lowering(pumped the brakes) then the crane structure may have been five times over its safe load. The brakes were too good. The Operator was maybe over confident and was probably the same crane and operator that lifted the shaft out of its housing to be worked on just days ago. Nope...wasn’t brake failure.

[@SCHMULBACH22]

[@GERntleMAN]

Sure. But things FLY sideways. And metal has a strange habit of having a lot of potential energy. If it's violently split, things go flying. And after they hit something and don't get stuck, they fall downwards closing the circle.

[@BrettonFerguson]

Hard hats and safety glasses.

[@crabbyhayes1076]

This is why they typically do inspections and a load test prior to a critical lift. This video also shows why it is also a good idea to stay well clear of suspended loads.

[@Rtoodeetoo2002]

@ 2m47 you see an infoplate of the crane. It says 'Proeflast, 60.000kg' wich means, maximum lifting capacitiy is 60 metric tonnes. If you know this and you want to lift a 75 metric tonne rotor, i think somebody is going to have to explain a thing or 2. In an average factory of this kind you have to have 6 forms in triplicate signed by 34 safetymanagers & supervisors just to rip a fart, how did this come to pass as a good idea ?

[@rybaluc]

One idea comes on my mind. Bean counters are not a weight counters. And day after a shift guy from finance department arrives and asks: Ok guys. Insurance company pays. Can you buy a new turbine,shaft and all those what you call? Engineer: The ball bearings... Finance guy: Yeah! Those ball beatings! I know Wallmart nearby. Perhaps you can buy all this stuff and we'll be back in a week or so. Engineer:But... Finance guy: I'll kick your butt! Go back to work!

[@guss1470]

True it was lifting more than it was tagged for but all rigging equipment is supposed to hold 5 Times what it is on the tag ( well here in America) but that does not mean you should ever over load the equipment and did they calculate the spreader bars weight too?

[@TheWireEDM]

Gary Mike Yes, rigging equipment has to hold about 5 times the proofload, but that doesn't pertain to the internal permanently installed components of a crane.

[@Squarerig]

The very comment I was to make but you have beaten me to it!!I was a ship's captain many years ago,on British ships,and the SWL of any cargo gear was never,never exceeded.Sometimes gear failed,wires carried away,shackles burst but never due to overloading.This is criminal!

[@nolansykinsley3734]

Rtoodeetoo2002 That wasn't a plate on the crane itself, that was on the yellow load beam used to lift the rotor, you can see it at 2:55 in the zoomed out view. That load beam is not what failed. It looks like they showed a gearbox that exploded for a second or two in the video.

[@alexmarkgz5939]

Ok here we go, as usual, a lot of speculation below as to the CAUSE of this failure. In Plain English, there were two reasons; 1.) As can clearly be seen at 3.03 there has been a Total Mechanical Failure of the 'Lovejoy' type coupling between the Hoist Motor and Gearbox. 2.) The Hoist drive train design did not include an Internal (secondary) Load Brake within the gearbox. Had this been incorporated the 'free fall' condition would have been arrested and the load 'held' despite the above component failure !

I worked with a 75 ton bridge crane and many rotors like this one. We used old, ratty equipment leftover from the cold war days, and even WWII. The GE guys knew about it, never said anything. Lucky we didnt have an accident like this. I was a rigger and didnt know anything at all. We used 1/2 inch cables for everything even though they were frayed

I was a crane millwright at a Bethlehem Steel BOF plant in the 70s. We had six 250 ton cranes (and I don't know how many 400 ton stripper cranes). When it was necessary to hoist in an entire 400 ton BOF vessel up 75 feet off the floor somebody had a plan. Replace the four 1200 foot, 1 1/2 inch cables on one of the charging cranes. 48 runs of cable. We greased and checked over the crane. Replaced the 250 ton limit signs with 400 ton limit signs. Hauled up the vessel and put it in place.

[@bcaffrey98]

If the turbine assembly was in fact 70-75 tons then the crane was overloaded. The inspection plate shows the workload (werkelast) of the crane at 60,000 KG or about 66 tons. Oops. It was structural failure due to overloading is my guess. The aftermath video shows where parts of the crane's structure failed (ripped out).

[@jamesstephenson5273]

thats 60 tons mate

[@bcaffrey98]

James Stephenson That's 60 long tons (2240 lbs/1016kg), son. I'm in American where we use "short" tons (2000 lbs/907kg). Either way, they were exceeding the crane's maximum workload capacity by a wide margin.

[@DarktroopX]

Bill C Since this happened in Europe, it was ofcourse "normal" metric ton (1000kg). However I believe they would never exceed the crane's max. capacity, since the turbine high pressure stage (this looks like HP) is extremely, extremely expensive. More likely the video title is wrong.

[@rm-cl8su]

i think that the inspection plate with the 60000 kg rating was mounted on the spreader beam. Every overhead crane I've seen in a turbine hall has the load rating to lift any removable component on the turbine hall.

[@phitsf5475]

There's always someone who reads the MAX LOAD as rough guidance and wants to play in the factor of safety zone. Not saying that's what happened here. Looked like a very rapid failure, no time to run away!

[@jinjitronic7457]

So the crane was rated to 60 tonne. Solid effort there boys. Solid indeed

[@RetroCaptain]

I think they "rolled the Dice" on this lift.

[@ostlandr]

Okay, making my American brain work hard here. A "tonne" (a metric ton to us Yanks) is 1,000 kg. The crane was rated at 60,000 kg so 60 tonnes. So if the rotor was 75 tonnes- major screwup. Happens all the time- people try to drive a 13' 6" high truck under a bridge posted for 12', or try to drive a 40 ton truck over a bridge posted for 15 tons. :-(

@HoistExperts Excuse me, but in the Netherlands they also have such inspections. And more than once a year. They are not notified when these inspections take place.

[@TheMILVET]

+ExtremeDeathman They pulled the old one, it must have weighted as much. It says the rotor can "weigh up to 75 tons", does not state the actual weight of the rotor. The data plate is shown on the lifting beam at 2:48 and at the top of the image @ 2:55. My thoughts; I think it was a drive coupling failure to the rope spool. After the failure, you can hear the rope spool winding down (from whatever speed it was spun up to). Also you see the cable and load beam being lowered down still attached to the spool. @ 3:05 is a Lovejoy type coupling broken. Either way folks, a perfect example of why you never go under a suspended load.

Well, i don't think they could hide this accident, because the repairs or better the new parts will cost probably several millions.

[@Antipodean33]

At least it didn't fall from 20 or so feet. Makes me wonder how the megalithic builders in Peru etc moved solid granite blocks weighing 200 tons. Not only moving these massive weights over mountainous regions and rivers, but how the hell did they cut these very hard rocks from the ground in the first place?

[@imchris5000]

+Antipodean33 they found harder rocks and hit them on the granite to slowly form trenches and cut it out of the stone also rollers make it a lot easier to move massive loads

[@Antipodean33]

imchris5000 Oh man, you serious? Have you any idea how mountainous Peru etc is? You believe men could pull 200+ tons granite blocks over mountains, across valleys and rivers and then build with such precision? Also where is the harder stone that granite and Andesite etc? It's total nonsense to think they achieved such work that way. I'm a bricklayer/stonemason by trade and i remember back in the 70s doing my apprenticeship and my teachers all said that it is a complete unknown mystery how they achieved such workmanship

[@imchris5000]

Antipodean33 they spent generations building that stuff also basalt is harder than granite if you hit the basalt rock in the same spots over and over you will cut a groove the Egyptians used copper sand saws to cut granite which are just copper strips that drag sand across the stone which quickly starts cutting so the sand is doing the actual cutting

[@Antipodean33]

imchris5000 Where the hell did you get such bogus info? Copper strips and sand cutting granite?????

[@rogervoss4877]

Yep, you could cut with string and that abrasive. Sand is most often quartz grains, matching the hardest constituent of the granite. The rest of the granite crystals are softer, particularly the pink feldspar.

[@jimsutch5461]

I agree, the load rating on the crane is 60,000 Kg or 132000 lbs. That includes all the rigging on the hook too. If in fact the load was 75 T or 150,000 lbs. the crane was grossly overloaded.One point about the failure is the coupling, it appears to be ductile iron or cast iron instead of steel. That might be a point of interest.

this same thing has happened to me, i operate a 45 ton Zenar. The brake failed, causing the coil of steel to slam onto the deck of the Semi trailer. The weight blew out the air suspension, the block fell on top of the coil damaging about 20 laps (.030 cold roll). I was glad the truck driver was clear, and no one was standing next to the trailer.

[@MrDJ217]

Everybody is bout to get fired

[@juliovila-cha6500]

Even if the high-speed brake failed ( between the motor and gearbox) on that size crane there is usually a secondary brake on the main hoist drum that should have held the load, if everything was set up correctly i.e. broken shaft detection and over speed switch. And if I am not mistaken there is a safety factor built into cranes which I think cranes must lift 120% rated load as per OSHA/ASME (American Society of Mechanical Engineers) requirements.

[@skyfix9813]

Notice the shattered coupling at 303...i work on lifting equipment occasionally and have never seen a coupler like that....all components are usually joined with splines...and then you shim them to match and prevent binding..ive seen hydraulic pumps shred those couplings twice...

[@michaelsteinbach5171]

Like a glove!

[@deathfrogg]

Looks like the flexible coupling on the hoist gearbox sheared off. All the weight of the load is on that. Regular cursory inspection wouldn't catch that, it'd have to be disassembled and either microrayed or magnafluxed to see the fracture. I wonder what the alloy of the metal in the coupling was. Looked like a fine crystallization so could be 4340 or 4570 forging or some other 400 series. Those couplings are used to compensate for misalignment from the output shaft to the drum shaft.

[@mspenrice]

New trousers for the guy who walked under the turbine a few moments earlier...

[@davidbuitenwerf]

Looks like the motor coupling(lovejoy) gave way, on this open winch style crane! Im a crane tech and honestly since it was most likely the casting of the coupling witch was flawed theres no way that annual inspections would have found this!! However what about the load brake on gearbox side?

[@rabie4x4]

Plant maintenance usually blames us operators for breaking things in the plant. I'm just glad no one got hurt. This just shows how mechanical stress on machinery adds up. Expect more of this as companies across the globe cut back on budgets resulting in less maintenance and inspections. If that's a GE rotor, it'll have to be shipped all the way to Schenectady for repair and the bearing journals re-trued on both halves of the rotor shell casing. Ops will have new criticals to learn on startup...

[@MickyMoz]

There's your problem.

[@adammarshall1762]

I know this is a very old video, and most of the posts are as well. However I feel the need to comment on this. A critical lift of this nature is indeed possible, with the right paper work and safety precautions. Neither the wire rope nor the hoist brake failed. The driveshaft coupling (lovejoy) did. Most likely stress fractures from a worn packing caused the coupling to fail. This removed the hoist brake and motor from the drivetrain. Leaving only the only gearbox to handle the load, which is what you hear whining just after the load drops. I am a crane technician....

[@dt90891]

Brake device failure.

[@kenparnell4297]

They also require an annual load test. Load test is done a 125% of the cranes rated capacity. That doesn't mean the crane can lift of it's rated capacity, the extra loadage is for safety's sake so shit like that doesn't happen. I know, I use to design bridge cranes, lots of bridge cranes.

Being a hoistexpert clearly does not make you a turbine expert. This is a steam turbine, not a gasturbine. Try flying a 747 with 4 of these.

[@azyfloof]

PLOT TWIST: Steam is a gas ;)

[@Paco357mag]

A gasturbine burnes gas, a steam turbine allows steam to expand and partly condense.

[@HoistExperts]

Sorry, that would be a gas turbine. Not sure what the confusion is. Used in power plants. Typically burn natural gas.

[@macestillmace2514]

I like how you think the only kind of gas turbine is ones used in jets...

[@dragonbutt]

You know what, challenge accepted. STEAM POWERED 747 AWAYYY

[@Rapscallion2009]

Ouch - i'm glad that guy moved when he did. Personally I would not be working under the darn thing as they're lowering it in the first place, though.

[@petemclinc]

Those nylon slings would make me a little nervous.

[@502c10]

guys, don't forget that even hoist brakes have duty cycles too. That wasn't exactly the best way to lower the load. The only regulations for a second hoist brake, other than molten metal, allows the hoist motor to be counted as the second brake, to control the lowering of a load.

[@inktvis009]

reason of failure: max load 60 tons max weight to failure: 68 tons

[@matycee]

jesus.... that was tense. I was on the edge of my seat for crying out loud. Watch your fingers..

[@schlaznger8049]

aaaannnnnnnndddddd perfect fit

[@babydriver8134]

The slowing and speeding of the motor while lowering put excess stress on the entire setup. Not surprised it failed.

[@bigchubby99]

The blades should have been fine if that bloody yellow beam hadn't fallen on them..

[@caratcranker5874]

+Joshua TenEyck  Scrap for that steel would be around $150 per Ton now a days, there, problem solved, you get your money back ! it was made in Swahili right?

[@joshuahenrichs595]

Yea man UPS dropped it off like that came with a mangled crane too

[@kecola]

Haha these comments are funny af!

[@tmdrake]

NICE! Need more failure videos like this!

[@savagedick8890]

where can I find a woman like that?

[@Mike44460]

@ 3:06 , this is the cause of the failure. This is called a Lovejoy coupling. Whoever designed this crane is at fault. The coupling is not designed for the stress it was subjected to in this application. For reference, when this crane was commissioned for service, it should have been subjected to lifting a load twice the working load limit a number of times.

When I was a kid my dad used to take me with him on the ocean because he was a fish farmer, I always hated the damn cranes, it always shivered in my spine standing under them when they had load. I do not know why but I guess I was born with common sense, today I am not standing more than 5 metres close to a crane with load specially heavy load. Imagine one of those wires snapping if you cannot use the hook? The wires can cut metal in half, I seen metal wires that were under 50 tons of load and one of them snapped hitting the crane itself which buried itself half the fucking way into the frame, you think these things are a joke? People take these things as a game are the dumbest creatures on the planet even animals have more common sense. The amount of forces in play here will kill if not handled correctly, a small mistake can fuck everything up and by the look in the video, a single metal fatigue was all that was needed to drop 75 tons and that moron walking around without a care in the world was lucky to not have that thing fall on top of him, complete and utter twat and I wish it actually did fall on him because it would serve as a warning to the rest of the damn workers to see what happens.

[@BrettonFerguson]

75 ton rotor. "Be sure to wear your safety glasses."

[@bogdog999]

I don't know if an inspection would have caught this. It may have been a defect in the motor coupling that occurred during casting..

[@nemo227]

I'd be interested in hearing what the insurance company said about this. I'll bet they had some "choice" names for management.

[@nos87stang]

I worked for a company as foreman did a lot of big jobs for them , I got ran over by an 90,000lb. excavator on the job and all of a sudden I was the worst foreman they had and should have been let go a long time ago. it only gets worst when you get hurt on job

[@gijs20081]

You are so perfect in everything. no failure ever happens to you in the US.

[@mel_energy]

Remember the Vietnam war? That was awesome

[@NuclearNinja1979]

Was I the only one thinking. "Bingo! It fits like a glove! Lets go home..." at 1:50? lol

[@BDCALLAIS]

Maybe calling someone to certify the crane,cables, spreader bar and pulley before making such an expensive lift would of avoided this!

[@oswaldjh]

Gravity is one of the ways nature can remind us who is really in charge here.
