The break looks clean. Usually broken parts like that have a pocket or rusty area where the flaw was. Crane must have been overloaded. That turbine still has a use. They can put it in the kitchen, hook a electric motor to it and it can be used as a giant lettuce shredder.
What a lousy coupling, it looks like grey cast iron, steel would never fail like that. This is what happens when you get accountants designing things. In the long run that cheap coupling turned out to be very expensive indeed so the accountants have failed again. I'm disgusted. By the way some kind of centrifugal brake would also be a good idea but have it on the gearbox input shaft.

It's such a 1000 times said common knowledge that people shouldn't walk underneath crane loads. But even at my own work I see people doing stuff underneath 2000kg metal blocks which are on a hoist. Seems like people need to experience a (probably fatal) failure themselves before getting the point.
Why is it people take, (particularly) a factory crane as infallible? There is no way you can hold this up, so stay out of the bloody way until it stops moving! Any bearing seals should have been fitted to the case before the Rotor went anywhere near it.
There is never just an "accident" Someone fucked up and didn't pay attention to details. such as crane capacity, maintance overlooked, or just plain overloading your lift.
Now both unit is damage. It will take over a year to rebuild the bottom turbine body and the turbine itself. Upper body somewhere and it OK. It would be better to get the whole units new and shoter time to replace.
At 3:42 they are shining a light at a space immediately adjacent to where there is an industrial electric motor. At 3:44 - 4:06 they are focused on a failed casting. Looks like a gear reduction assembly failed.
Were the causative factors for this load drop formally announced? Appears to be fatigue crack initiation line along outboard edge of the brake-wheel coupling. And note the input shaft to the gearbox is completely gone. Any idea of the coupling manufacturer?
@gulfwelder the civilization of america with white people has only existed in what, 500 years maybe 400 and my country is what 10.000 years older, so you stfu, you dont know a shit about being smart, ever heard the word the old ones is the wise ones. look at our energy processing, we use wind energy and water energy sun energy we dont use coal plants or nuclear powerplants we are one of the countries with most experience in Agriculture. usa = armargeddon
If you look at the close ups you will see a failed coupling,probably between the motor & hoist drum gear box.,Or it could of came from between the gear box & hoist drum shaft. I do agree that the demags are good cranes but a provincial crane is superior. They are a Canadian crane. ONCE AGAIN,,,it cannot be stated enough NEVER EVER go under a suspended load... Even if your Stupidvisor tells you to......
why do you americans allways think you are so fucking clever and smart, you are nothing, you are the youngest civilization on earth, go take a shit load from your mom,
"from a dane, in denmark worlds happiest place on earth and the oldest kingdom and one of the oldest human civilizations on earth, uhhh and we got the oldest flag" THAT IS HOW YOU AMERICANS SOUNDS, EVERY SINGLE ONE OF YOU BRAGS, OF HOW YOU GOT THE BIGGEST ARMY AND THE SMARTEST PEOPLE, BUT NOOOO YOU DONT BITCHES,
@duskedennis your right.. youngest and smarter.. what " Shit load from my mom... " ok and im guessing that was clever right? Nice ! And u actually went there about out ARMY... i guess that was smart too? Facts still remain. Google it.
@3Mudbone1 your pathetic and your mom is pathetic but most of all... the american people are pathetic. home of the pathetic. your capital "pathetic D.C." and your president barack pathetic.
Like many others have said, what the hell were those clowns doing under a suspended load. I worked in cranes and rigging for a few years and if there is one thing you learn on the first day it's don't be under or near a suspended load.
@dishortt1 Yeah I'm pretty sure you are right. I dont remeber a 7fa having a center bearing. Could be a 7fe at least I think thats what we tore apart in birch bay. It had a center bearing. Hard to tell without getting a closer look at the case.
Here is a good reason for workers never stand under a hanging load.
Im working in a paper mill with several cranes over 50t recently during an new steam turbine instalation an 45t crane with only 5 years got replaced for a brand new one also 45t.
Just to be sure that it would stand the load its much cheaper a new crane than stop energy production for a very long time these turbines arent cheap and they cant be found in stock any were to be replaced in a few days.
Oh boy,..that was very close call for the guidemen!
Happy they survived this. It was about 5 million USD loss in the blade assy alone, never mind reworking the lower case,..not to mention the ruined crane. Fractured casting. It looked to me it was being lowered too fast. I mean before failure. It appeared to be 10cm decent, stop,..10cm drop. It (crane) may have been past due for overhaul. A "magging" would have revealed the hairline crack, saving the accident from happening..
was this a konecrane??? European crane manufatures are allways pushing the limits to keep the cost down. This is a perfect example of low cost cranes, it looks to me like this crane is spankyn new.
Vous êtes vraiments sur qu'il y ait eu des morts ???? Il y a 25 à 30cm entre la pièce et le socle. L'espace n'est pas suffisant pour que quelqu'un se trouve dessous...
not a very controlled lowering of the load, did the operator overwork the hoist brake?, they do have duty cycles too you know. sounds like the brake may have failed (heat) allowing overspeeding of hoist components caused coupling failure.
A hoist this big should not rely on one brake even if the motor brake fails the second( mechanical load brake )will control the load from free falling.
When a mechanical load brake is not used you must control the hoist motor with a Vector drive.
A hoist requires 2 methods for controlling the lowering of the load, regardless of capacity. The exception being hot metal carries, which require a load brake. The hoist motor is accepted as a second method of controlling the load. Other methods include Eddy Current Braking Thyristor Drive Pole Changing Motor Statiic Stepless, VFD's with feedback, I've even seen Foot Brakes w/ cab cranes. I believe you can find this in CMAA specification 70. "Vector " drive is a great option, but not required.
Amazing to finally see a crane accident vid that wasn't user error! Cranes are marvelous machines, but this proves that anything can happen at ANY time!! As already mentioned, never put yourself UNDER a load. Man. this is sobering.
This is the reason why you NEVER put yourself below any slung weight, the guys aren't even guiding it, they are milling about for no reason. So lucky the failure wasn't earlier or from a higher position. Glad no one was hurt and everyone involve will learn a good lesson.
