- 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.

Love all the Aussie nicknames for people in serious positions. “Here is the leader of operations, Wazza”
That's just a normal thing here mate.
In one of my jobs when I was a young fella, I was able to lift much heavier loads than the older fella's I worked with, and my name is Ryan, so they call me R Bucket, and ordered me a bucket hat through the company with it emblazoned on it. And thats how I got my name, That's just how it goes here haha.
I head a large cyber security firm now, but I'm still called R bucket, and I still wear my hat 😀
Why, I she your girlfriend?
"With such a straightforward task, what could possibly go wrong?"

Work is a four letter Word
@@brucesorensen3252 a word the rich can't understand.
not to mention the radiologists considering all the coal they are constantly around
Lol! Yeah, the work done here wasn't optional, but with an excellently designed machine, the process could have required a smaller amount of troubleshooting. But the RICH would rather pay these guys than pay for an excellent design. It's cost effective. They keep more of their money.

"Weren't planned for removal." Yes, they were, which is why they're there. No matter how well-designed, all machinery breaks down on occasion, which is why things like removable gearboxes and motors are used. The owner of the machine might keep spares on hand as well. Then there is PM, and preventative shutdowns, where things are removed and rebuilt, to keep the machine running.
Things, such as bearing housings in the large weldments, if they're worn out, are welded up, on site, and bored out by portable boring mills, where new bearings are then installed. Everything is designed to be repairable, especially on these multi-million dollar machines.
P of
Obviously not designed (or poorly designed) to be repairable in the case of the coal scoop! Maybe repairable for non-gravity situations but that's not what we have here. But it was probably advertised as being easy to maintain long term.
@oidbio2565 its one thing to spend $1k on a device you can't repair but this isnt toloerated in the $1m+ range wtf
@@cybyrd9615 Well, that's the thing, isn't it. It IS repairable. The question is, how well designed is it for a reasonably smooth repair process. That's what I'm talking about here.
I hope they brought along a good assortment of o-rings.
Hats off to all the Men who keep society running smoothly and take pride in Their work. They do it for Their families.
They make really good money though and the jobs seem very fun.
I used to work on heavy machinery, there was always something going wrong when working on them, something siezed needing cutting, something needing a sledgehammer or something breaking while demontaging it.
It was always under time constraint, and everyone shouting about how much it costed them that I took an hour extra when shit was stuck.
I was going to work long into the night on a machine, and the owner of the machine saw me cutting a row of rusty clamps that costed $5 each, and he told me they were reusable, so I packed up, went home in time, and restarted where I left off the next morning, unscrewing the clamps by heating them with a torch, wirewheeling them and repainting them, taking a good hour to save the last 5 clamps, at the end of the day, I had about an hours work left on the machine, I walked by the owner and said "Time to clock out, it should be done within an hour tomorrow morning" He then had to pay me cash in the hand to stay an hour extra and finish his machine, and I wasn't cheap.
But it was always the same, and I had enough and quit soon after that incident.

I used to do this type of work. I miss it badly, loved working with a good crew and chain falls and ener-pacs to remove and repair broken equipment. But once your health changes your heart breaks 💔
Man I felt this in my soul. I was a pipefitter but broke my back. I miss it badly every thing I used to complain about I remember fondly now lol. I don’t know if it was the mental or physical challenges or have a great group of people around constantly but life’s not the same stuck at home.
Was a millwright for a few years in a press shop. Do miss the guys and the pride of getting some heavy stuff back in working order.

That pentle pin bushing bore-out fix was a rare barbed-wire wild-west moment that would probably cause most FAA materials & manufacturing engineers to swallow their tongues.

@@clown134if it don't fit don't force it. As to aircraft precision perfect is the rule. Poor maintenance or lack of same has caused many plane crashes. I'd say the landing pintle needed to fit perfectly out of the box. A master Machinist honed out the bush. For me that would work on a motorcyle or car but not certain about an aircraft at all. That procedure would have to be recorded as it modified a part. Also - 40° is not an unusual temperature for an aircraft. That also must be factored into parts by the manufacturer. No mistakes is the rule I'd say.

Some skilled mechanics freeze the bolt and heat up the whole piece and is way easier to change the bolts
weld lifting lugs on the base .much love and respect
My dad would’ve loved this he was always watching things like this
Wow Very interesting !!! Question. Thousand or so years ago what was the process used to separate the silver/gold. Was Borax and zinc used ? Thank you
Just like they still separate gold in the Amazon jungle. They use mercury. It sticks to the gold and sinks because it is very heavy. Then it is put in a pan over a fire and the mercury evaporates leaving the gold behind. All the gold melts and runs together to form larger nuggets. Not very safe breathing in mercury fumes.
Now I can repair my Tonka trucks, great tutorial.
This show is a prime example of why we have phrases like yada yada, and bla bla bla.

Roland as long as you don't believe everything posted on TH-cam folks will be ok. But usually if you have some knowledge of a subject you will overlook many things. I agree with your comment though 100%!
I’m so high rn, I learned more off this than I have in school✌️
it's always doug and his team showing up
All machinery is meant to be disassembled for maintenance, tight bolts are meant to be tigntend and loosened in a particular order especially when under exstreamly high torque, usually heating up the bolt or nut with OXY aceterlin torch helps,and making sure they are properly greased, and you need one or two qualified mechanics overseeing the job so that everything is done right ,Its only hard if you make it hard ,a job is a job ,
We won't see adoption of this technology in my lifetime. Or, given that I'm 70, most everyone else as well.

With that telescoping lifter, jack up the front of it, pop the pivots out of the hydraulic cylinders (the bracers), and swing them out of the way. Roll the sucker out. Hydraulic pressure should be dead, if lines have been cut. If they haven't bleed the lines. Hell, that might solve the bracing issue as well.
I know right!
Exactly what I was thinking and they eventually did pop the pivots out but only after craning it out.
I would have bled the lines immediately.

Why didn't they weld the lifting point back on the long wall jack?
Rattle gun I always have called it impact
Very interesting. It just goes to show that engineers don't know everything. Great video.
I worked for a Japanese company and the engineers valued experience. We had to report a problem and basically teach them about it with all pertinent info and root cause if we could define it. They told us we were the experts until they could grasp the problem. Completly different I'd say to North American engineers in their approach and being humble. It took time to gain their full confidence, but one you did you could say I think or believe and they would listen. I would only give solid facts and any question I could think of I answered before sending a report.

It was always under time constraint, and everyone shouting about how much it costed them that I took an hour extra when shit was stuck.
At 24:50 worker has a lapse in judgement that could cost him a hand. Can tell his hand is a bit to the side, but absolutely no reason to put it there since it is his brain tricking him to think he is doing something relevant. This type of work only takes seconds of poor judgement to have devastating consequences!
Why didn't you guys use heat or even heat and wax to get the large bolts out? Also, why didn't yall loosen the hydraulic hose retention clamps when you stretched the hoses apart? Couldn't what you did cause stresses and possibly premature failure? Just wondering.
it, hard to tell just from the videos, in my experience when ever I come along to see what everyones struggling with and ask the obvious questions like that there's always a reason why on that specific job its not possible... so who knows is guess. but I'm curious to know as well.
Even the most conscientious repairman take shortcuts. You hope they really don't short -cut the safety...and their unions can hopefully protect them from the toe -tappeing- clock- watchers profit motivated bean counters.
I don't think the bolts were seized, it was just the side load and pressure I believe. Wax might help but heat would only expand them and make it worse IMO
Nope heat would cause everything to grow. A heavy wall sleeve over the bolts and hollow ram then the nut for ram to push against and grease the other end as jacking against the other end would even cause bolt to mushroom before entering the bore. Fitted bolts are a gentle exercise and metal no matter how high tensile can deform.
As well as something to support the weight of gearbox.
Airbus Landing Gear Pintle Pin R&R.
I love the way they over dramatize the pintle pin nut problem. Nuts refusing to go on even new parts isn't really that big a deal. In this case checking the threads on the new pin is the first step in solving the issue. Threads on new parts can have small pieces of metal from the machining process stuck in the threads. Cleaning the threads is fairly straight forward using a thread file. This will also repair the threads themselves (if) the threaded are was bumped on a solid piece of metal creating a slight dent and burr. This could happen if the machinist was a bit distracted while removing the finished part from the mill.
Yep they presented the nut stopping due to dirty or damaged threads as more complicated than it really was.
That's reality TV for you, if they hit a boring part of the video, create some drama by making mountain out of a mole hill.
Better they do that than not make the show at all because the execs say its too boring
I couldn't believe it took two shifts for someone to figure out to clean the threads, that was the first thing I thought of, and those guys are supposed to be at the top of their field, they probably make great money. I wonder if it really took to shifts or did they just say that for drama?
@@bigredc222
All for drama to "fill" time, plain and simple.
When I was in the AF and we ran into this problem alot. First thing look at 5he threads and if they're not messed up, just spray WD-40 and clean with a wire brush. If the threads were damaged, then reach for the thread file to fix the threads, then follow that with WD-40 and a wire brush to make sure the threads were clean, and our shop did not work on the planes or any part that could potentially be attached to a plane.
There is very little reality in Reality TV.
@@cynicalrabbit915 I collect antique tools, I got this little dead blow jeweler's mallet with a brass head, it was made in 1888. It had threaded 1" dia. caps that held leather under them. The caps had super fine threads maybe 40 tpi, and both caps had been cross threaded. There's no thread file that small, so I found a tap with the correct tpi and used the cutting edge of the tap to scrape the threads clean. They showed them doing something similar with a thread gauge in the video. It took a silly amount of time but I saved that 135 year old little mallet.
@@bigredc222
👍👍👍👍👍👍👍👍👍👍
Except for a few small screws most of the messed up threads weren't more than 20 tpi. Plus brass is very soft and easy to cross thread. I too have used tap and die kits to repair threads but wanted to keep comment to a small wall. Besides i thought that thread file might get a Q or 2 from newbies or uneducated.
All this heavy repair is like dancing with a clumsy giant.
I retired as an OSHA certified journeyman mechanic who worked on heavy equipment. We had to fabricate special
devices many times to complete a repair job on the fly.. Always told it's costing 100k per day it's down.. FIX IT!!.
Worked in a mine for 10 years the executives act like they're going to go broke if a machine isn't operating they just want their hundreds of millions of dollars every single day anything breaks they want it fixed fast fast fast even though it's brutally hard
You'd feel that way too if you invested hundreds of millions of dollars in something
@@UserNameAnonymous well the way of the world is huge profits. But look at the machinery the mine has to deliver coal. Millions of dollars invested. High wages for all the mine staff not to mention training the same.
I'm no fan of coal. But those workers are for living. My two grandfather's were coal miners in County Dunham England. They busted their ass for meager pay. My mom's dad was a pioneer for The Durham Miners Association 1869. Got his 50th anniversary cert on the wall. Lost an eye and his pension was a Big Brit Penny per month. Both grand fathers died of mining complications abd they could really only put food on the table Rambling a bit but mining and mining support is a hard job to this day. Good luck Aussie coal .ine employees.
Damn boilermakers!
Is there a specific reason why the aircraft mechanics are using hand tools only? I'm a diesel mechanic and I have cordless drivers and impacts. I haven't used a speed handle since school, and I thought it was interesting that one of the techs in this video was removing screws with one.
Aircraft mechanics working under FARs provided by the Admin are not permitted to use impacts/power tools on aircraft. I’m in A&P school currently and we do everything with hand tools
@@vincentmckinnon9152 Thanks! I wondered if that was the case.
@@tanyaerskine7657 not exactly. Plenty of use of power tools. A lot of aircraft parts are designed with much slimmer load margins than other stuff, to save weight, and a lot of aviation applications frown up on impacts or explicitly ban power tools entirely. But for the most part it's pretty common and it would be pretty stupid to regulate that out entirely. Electric ratchets and bit drivers are by far the most common as most aviation torque isn't very high. And when it gets high you get a torque multiplier and a 5 foot torque wrench or breaker bar.
I would imagine that there is too much risk in overtorquing or damaging the more delicate and thinner aircraft materials made from lightweight stretchy alloys and composites.
45 min in day shift says "it's raining so we are going to go home and leave it to night shift" yep get use to that boys, plus do be surprised when day shift gets the only celebration party if you do anything right...

Would have just melted those bolts if it wasnt a fire hazard at the time.
One thing you learn when you deal with alot of rust is oxy is almost always faster especially when you have to replace the bolts anyways.
Couldn't they just have a whole bucket wheel that they could swap in and out and take the old bucket wheel and repair or replace whats needed and have it ready to be swapped back in on the next cycle or would that just be to heavy to actually do
