Coal Machine Crisis: The Race To Repair A Supersized Machine | Mega Machines
Вставка
- Опубліковано 4 жов 2024
- On this episode of Mega Mechanics, at the world’s largest coal export terminal, high voltage cables are causing some real problems for leading tradesperson, Dan and his team. A shutdown is ordered, but before anything is off the ground there’s an issue. Big bulldozer rebuild has the heat on Shane to stay on track at the Hastings Deering mine shop. Bringing these mega machines back to new takes temperature and tools to the extreme.
Across Australia, the wheels of industry turn 24 hours a day, 7 days a week. These machines are tough and the teams of people running them are even tougher. From deep underground, to high in the sky, these heavy metal marvels are essential to our daily lives. But, what happens when these massive machines break down? Teams of mechanics, engineers, fitters, and boilermakers step up to battle against tight deadlines, in some of the harshest working environments on the planet.

To finish the reeler a full day ahead of schedule is a huge deal. I can personally tell you that NEVER happens, especially at a nuclear plant. So I guess we all know who will be receiving the next contract, don’t we! I applaud their efforts in the reel rebuild. Myself and my journeyman rebuilt the entire control board in stacker reclaimer #3, at Crystal River unit 3 in Florida, in only 4 days. No faults. We had 5 days to do it. If you understand what I’m telling you, you will know that is nothing short of a miracle! Thanks for sharing.
I love that people who work with their hands are the star of shows now, it's about time.
I'm a barber. That makes me a winner?
There is only ONE RULE IN EXCAVATION/DIRT WORK, it’s not if your equipment will break down, but WHEN!!!
A good team of mechanics are a must have in a mining op.💪 lord knows our crew would be hold’n down the couch if wasn’t for our gear heads💪👊 cool vid guys👌
I had to take a bunch of safety courses and there are lots of rules actually.
Einstein.
Farming, trucking etc...
Maybe they could really hype the video up a little more by putting sirens and flashing red and blue lights on the service trucks and have them race to the scene of the _"emergency repair!"_
It reminds me of Batman and Robin. "Will our repair fighting crew succeed on time or will the world stop turning because of a $3 bolt? Stay tuned for next week's exciting adventures.
Lol. It gets tired quickly don't it?
How about some explosions?
Lots of mistakes in the script in this show, they need to have an actual mechanic with veto power over the script lol
The major ones are that the grease put into the D10 near the end is actually what pressurizes the track tensioning cylinder and keeps the track tight. It has nothing to do with lubrication. It DOES reduce wear, but not because of lubrication, but because a loose track flopping and banging around wears everything out much faster, and so keeping the correct track tension leads to much longer life.
The other big error was when the train motor was being replaced, and the shim was added, and the narrator said it was talking to give space for lubrication, but that's not accurate.
He was setting the Backlash on the drive gear, which is how far the teeth mesh with each other.
Put your hands together so your fingers mesh like gears, and try turning them. Notice how if they are too deep in, they bind and rub on the opposite side? But if they are too far out there is lots of slop and looseness, plus the load is all on the very tips.
In gears, if you have them too close together they rub on each other wearing it out and creating lots of heat, and can even bottom out and jam.
Too far apart and you are loading the tips of the teeth, plus every time you accelerate or decelerate that gap between the teeth let's them slam on each other.
Backlash is the measurement of how far one gear will rotate without the other one moving, it's how manufacturers specify how to adjust the gears.
So when he first put it together, it didn't have enough, or any backlash, so he added the shim to slightly seperate the gears and get the specified backlash reading.
There!
You now have more technical details than in the rest of the show script combined! Lol
There were several other issues, but I didn't memorize all of them lol
Oh, and the DRAMA! cut it out! You go on and on repeating yourself time and again about how every moment is so important and lost revenue, and then you cut to the most important people standing interviewing with you.
I have worked on plenty of high value jobs where time was money, and I wouldn't have had time to lollygag for the camera lol
I think the worst was the train lift, where you took 3 or 4 segments building up the lift not working, and not actually doing anything or even telling us what ended up being the problem, and chances are that you asked them to make the light blink and staged the whole thing lol
I enjoy the subject matter, but if you aren't going to bother with technical accuracy, and are going to treat your audience like idiots, I will be careful not to watch any more from you.
Which is sad, because you get into excellent locations.
Outstanding comment...thanks, PB
Couldn't of said it better myself. Yes, time is money, yes corporations don't like down time, but people aren't going to die if everything doesn't exactly follow schedule. These aren't dentist appointments, stuff happens, things go differently than expected. I noticed a lot of other comments saying the same. Maybe I'm wrong, but its totally unneeded. This shouldn't be in the drama category at all.
You have to figure theres going to be a lot of people watching this that know at least some mechanics. Would of been a good idea to have someone who is knowledgeable fact check the script. Those mistakes were pretty basic, and trivial.
You are correct. When he was talking about the backlash on the train gearing I thought hmmmmm.... that's not correct!
Funny, you seem to think all these 'reality' shows are accurate. Drama is what keeps Average Joe's eye's from rolling back in their heads. Without it, we'd be still be watching sitcoms with canned laugh tracks.
ok
The machine (crane) used to fix the machine (cable roller) has broken. And the truck that transport the roller is too wide to go to repair at this time. Murphy's Law in relief. But somehow these men getter done! I love it!
They all sound like Kurtis from CEE :)
Además de que tienen uniformes similares jeje
Yeah,and some of them wearing the same cloths like Kurtis..
We are all the same as Kurtis,, A real Aussie is a REAL Aussie
@@jefflawrence3846 how about Ozzy man..
Who's that?? I know there's a Carl from CEE 😂
37:33 grease isn't applied to prevent excessive wear. It is used to tension the track, as the track assembly is basically one big cylinder, like ones that operate on hydraulics.
Austin Clarke lol good catch
I was just about to comment.....
You are correct in part of your correction lol
The addition of grease DOES reduce wear and tear, because when you keep the track properly tensioned so it's not flopping around, it lasts MUCH longer.
But yes, this application of grease is to pressurize the track tension cylinder, as opposed to lubrication.
Actually dozer tracks are not greased. The dirt would stick and cause far more wear.
@Hello Austin Clarke, How are you doing?
To all the highschoolers watching, there is some pretty good $$$ in these jobs especially with overtime. It beats an office job where they say reasonable overtime is expected in contract and not pay you for it
How is it that other people can do better on showing the repair process than guys with a whole film crew at their disposal?
I'd be pretty mad if my $500k cable had to be fixed before I even put it on.
A little electrical tape and you’re good to go, lol.
You know, there's an upside to aging and experiencing short-term-memory-loss, because apparently I watched this video some time ago (as indicated by my "thumbs-up" selection already shown on the video), but I have no memory of watching it, so I get to watch it again today as if it were the first time! 👍
I would love to work in a mine like one of these. I been a truck driver for 12 years in USA and been to lots of mines and pipelines and worked around a lot of machines like this and I would love to work in big mine like this as an operator. Or driver. I love heavy machinery like this, ever since I was just a kid. In a way I guess Im still just a kid playin in the dirt.
Why don’t you spend your time applying for a job
44:01 ,I thought the boys were warming up for a nice tic-toc video.
If they need full time dozers and machinery, they need spares of machines, assemblies, and whole machines, to keep work going while the inevitable service and overhauls are in progress.
Written and produced by a whole flock of DRAMA queens.
agree
Totally agree. This whole concept has become very conry also. The text, the voice-over guy, the editing and the actual not-so-checked 'facts'. Ah yes, and there is always the deadline thing and always the mayor setbacks. Well, if there were any serious setbacks and they still finished the job in time something did give. Doesn't sound too safe to me anyway.
I don't agree. I'm in awe on how cool-headed the engineers are. Ordinary people would be cussing up a storm, or quitting in disgust, anytime they face a challenge or a gunky job.
@17:49 - I was expecting to see Marty and Moog at MCM (Mighty Car Mods)!!! 😂🤣
Why didn’t they just order a replacement from super cheap 😂
Turn off electric b4 starting work on electric connections. At a rural setting in north Thailand, with 220 ac, I disconnected the main breaker, walked 200 meters up the hill, ....then POW!, got a shock! I was pained & dumbfounded & cussing. Walked down the hill, opened the breaker box, and found a gecko inside had fried himself between the contacts, thereby keeping current flowing.
Thanks in sharing your video. Appreciate very much and I like it.
Always stay safe in all ELECTRICAL activity..
I admire these men they know they are the heart of the operation with out them there would be no coal........
Those mechanics are cool-headed. Ordinary people would be cussing, quitting, blaming others, on & on. These guys see a challenge, and fix it, ....then on to the next.
I could do without coal and as a matter of fact I do.
It is my dream job I love this 😍💙💙❤️👍 beautiful machines 😍🌍🌍🌍💯💯
As an electrical engineer and contractor, I've installed thousands of feet of specialty cables. That reel of cable should have had lagging for protection. The manufacturer of such special cable should be held accountable for shipping a exposed cable. Any repairs made on-site to the cable sheath reduced the life of the cable by 50%. Totally unacceptable practice.
I can't understand ignorance when it comes to literally the biggest machines on Earth.
On another note I find it pretty amazing just how much power these machines consume. Isn't it around the equivalent of 20,000 homes for this machine to operate and it also blows my mind that it's fed directly from the power plant through it's very own transmission line cable.
Camera crew shows up.
Everything breaks.
theese people have deadlines to meet and shit. They dont have time to make a tv show and put everything on halt, what they could have done, is asked to come around the time where stuff is usually repaired or needs changing.. OR .. It really IS that hectic everyday
I wonder how the Scot working on the train ended up in Oz.
government has had a skilled migrant poaching thing in action to plug the trade shortage for years the issue like any first world nation is all kids want a university degree and easy job vs doing an4 year apprenticeship and hard work so they steal people from other countries to plug the hole
@@tcollogan Nonsense. Australia is a penal colony. The criminal Scot was sent there for his crimes.
@@deconteesawyer5758 LOL
Months of planning - Where is the second, spare cable and reel. Swap them out. A few days and that's it. The original 18 year old equipment goes in for a proper rebuild and then is a future stand-by for the next major repair.

E/Z ROBERT WHEN YOU HAVE DADDYS CHECKBOOK IN YOUR BACK POCKET IN THE WORLD THE REST OF US LIVE IN ITS CALL A BUGET
I'd Hate to have all these men change a light globe at my house I'd be exhausted listening the commentary Just as well they get all there jobs get done just in time as the world could end.
7:15 The answer is Monty Python and the Holy Grail.
I saw that too and was about to comment haha
Caterpillar got a nice representation. Wonder how much they have spent on Cat machines?
797 haul truck cost around 6 milion us dollar and a d11 around the 3 milion us dollar
The other good mistake or drama was the truck with the bright shiny freshly painted power spool supposedly waiting to be taken to the shop for overhaul
Wildest thing about this video was finding a cranie that wasn’t on a constant smoko.
That was a fascinating video 📹
i absolutely LOVE the contrast of the fresh new paint on any of the overhauled parts and machines
Mark , you are tops.
Do not forget your private padlock to keep in your tool box for next reuse.
Labor goes to QLD and says they support mining and families. Then they go to Melbourne and promise to abolish mining. Who do you think they will betray if they are elected?
They said "Japan and Southeast Asia..." Afraid to say China? Because thats where most of that coal is going to.
If China stopped importing coal from Australia, those mines would go bankrupt..in 1-year
@@chadsimmons6347 the greenies are blowing up the coal fired power plants...
@@renelaizer6518 (LOL) the greenies dont realize that without coal, you cant build, ele-cars, wind-power generators, bicycles..(W-T-F)?
@@chadsimmons6347 what they also don't understand is the fact that the turbine blade which weighs tons is a spinning mass driving the generator plays a crucial roll in the power output during peak demand. Because people demand power from the grid during certain parts of the day you have to deliver this energy without crashing the entire system. The spinning mass of that blade holds the entire system in balance. I think scholars in the future will point out that this society demonized the very thing we exhale as a pollutant. Maybe we should stop having kids now? People need to stop making irrational decisions when they are so emotional they can't think straight. Politicians use this human flaw to their advantage to gain evermore power. But hey certain people in power right now are changing the status quo....
@The plan Nevertheless world goes in direction of using less coal and oil,which is good for less pollution.China has same goal,less coal.
It just turned 18 and Peters going to give it a good birthday. Weirdoooo.
Calling track pads shoes... U wot m8?
8:30 Just based on my experience working on equipment; because the cameras are here that's probably the only time this guy has ever left his office.
His shirt is way too clean.
Can’t believe I just watched 47 minutes of this lmao
Oooh, It's 600 volts... That's nice, but what are the Amps? and he's an electrician...
He was talking about the dangers of it, thus the 600 v was important.
The amps aren't that important, but if you care, I am sure that you can estimate the size of the wire and the length, and ballpark the capacity of the cable lol
@@ke6gwf amps are what kills you. A taser can make 20,000 volts from a 9 volt battery. It will suck to get shocked, a lot, but is designed to not be lethal. Those lines in the show, even with minimal amps, would absolutely cook you dead in a hurry.
@@ctdieselnut you don't understand what "it's the amps that kills you" means do you? Lol
I often get shocked on 12 volts working on car batteries, and there is a lot of amps there, but the voltage is barely high enough to feel, not enough to cause problems (usually... lol)
But when you take the voltage high enough to start penetrating deeper into the body, then it only takes a few milliamps to stop the heart.
By definition, a 600 volt power line will have plenty of amps to not only stop the heart, but barbecue it and turn you into a cloud of mist.
So in this case, the ampacity of the cable is not important for lethality, because it could be a wire the size of your hair, and still kill you at 600 volts.
Basically, a power line like that has essentially unlimited amps available, far above the milliamps that are needed to kill you, so it's not a question of the amp capacity, but the voltage.
@@ke6gwf finally someone who understands. Every time I see people comment “iTs tHe aMps tHat kill yOu” as if volts don’t matter, when both amperage and voltage work hand in hand.
Umm doesn't he say 6,600 volts??
I'll bet these guys ain't paid enough. Go on, ask'em.

Fiber optic is not voltage cable it is data cable. Digital. Not analog flow of electrons.
How many hiccups can we turn into a potential disaster today.
Wow. . .incredible really great amazing😅😅😅
I'll save you some time,at some point everyone is waiting!
But can they meet the deadline ? Everyone is holding their breath !
Ok grease was not applied to reduce wear it is used as hydraulic fluid for the piston that tensions the track

24:26 no such thing as clean coal
why
@@allenelswick6961 The term is fundamentally an oxymoron, there is no such thing as clean coal, only cleaner coal. More efficient use of burning coal, capturing more of the toxic chemicals that spew out while burning it. etc etc.
its like saying something is 100% efficient, it can technically be 100% more efficient, but nothing can in of itself be 100% efficient.
@@Arcticwhir One of the funniest things I have dealt with working in the coal industry is Green Coal otherwise called Synthetic Fuels or SynFuel for short. The terminal I worked at during its production of SynFuel would ship Steam coal in by rail car, unload it into a stock yard and then send it into the SynFuel plant where it would be crushed into smaller pieces and coated with liquid latex and it would magically become "Green Coal". Nothing about it was green. The latex would just burn away the instant it saw flame and did nothing to change the chemical properties of the coal or the toxins emitted while burning it and you could charge twice the dollar amount per ton for it... Stupidest shit I ever seen.
Volts do not move, Amps move.
Management there for “support” yeah sure 😂
Its easier and cheaper to just replace the damn track idler on the D-11, they don't cost that much (about 900.00 USD), you spend more time welding, annealing, machining, and reinstalling it. total waste of time.
Everything is dirt cheap in America
Not o much in Aus
Closer to 5 or 6k
Love show
To much drama sheez its not days of our lives
It is a bit surprising that a fiber optic network remains the most efficient technology for an interlinked communications system in 2021.
Surely some manifestation of wireless connectivity would be far more cost effective?
These large scale mines are getting dedicated 5G setups now for local comms and centralized control centers that are thousands of mile away.
A documentary about an Australian mine operation but the uploader has decided not to allow us Australians to watch it due to geo blocking... luckly I have a VPN.
Great show

Just wondering how is that guy the head elektrische ? My Cable os scratched what am i to do ( 44:00 )
The best part was when he said: “ we don’t want to bend the cable too much” 😂😂😂 cause of the fibre optics. ( 46:15 )
And just wondering: why don’t they put the hole RIG on train tracks and have high voltage power lines running above the tracks. I come from Switzerland and our train tracks run via that system and they are at 15000V and at a frequency of 78.5Hz so why don’t they do that ?
Lock out, Tag out, Try out safest way to work
No dozer, Click bait. Report it.
ok video, kind of, I just wished they would concentrate on one issue and have that completed then move on to the next one instead of jumping all over the place which is very confusing and we never really get to see the work being done, also stop reintroducing the leads managers and workers it's cheesy and starts to sound like the regular reality tv junk.
God I would love to drive a mega haul truck to work. It'd be just one long wet dream the whole drive to work. Then just parallel park on top of some cars, hop down the stairs, and walk past slackjawed coworkers as I go into the building..
I think I won both the pissing contest and the 'biggest penis/ego/most insecure award'. Wonder if they can just put all 3 plaques on one award, like just the little tag as to what it's for? No? Damn. Screw it; just get me a ten foot wide by 6 foot tall bumper sticker that says "SCREW YOU"!

WAY, WAY too much drama. False drama. They need to get a different script. No, the world will NOT END just because a mechanic drops his wrench during critical repair.
Its obvious u don't see delicate little fefails preforming repairs on these machines!!

Now that's a waste of money for a stupid fiber optic cable. Power cables are fine after 18 years of service. Just run a new fiber optic cable and a whole lot cheaper.
Most likely the cable was starting to get old, insulation cracking, metal fatigue, etc. It probably had been repaired many times over the years, and just was getting tired, so replacing it was a good idea.
This is a drama show, and the writers don't have a clue what the subject, but everyone understands what a broken fiber optic cable is, and that was probably the last straw.
*_"Clean coal"_*
No such thing
You don't say...
@24:24 'The extraction of 13,000 tonnes of clean coal every day'!
No such thing as 'clean coal' - another grossly misleading two-word slogan by the LNP airheads-in-charge.
Too much attempt at drama....won't even show a trouble shoot or repair...misinformation on loose dozer track...
