"With such a straightforward task, what could possibly go wrong?" the segways between the segments are the most dramatic and ominous narration in any documentary I've ever seen

Love all the Aussie nicknames for people in serious positions. “Here is the leader of operations, Wazza”

A follow-up series showing the insurance adjusters, physiotherapists and orthopedic surgeons treating these fellows as they age would be interesting.

"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.

The most intimate description of outback lovemaking 25:23 - 25:28 Absolutely epic.

2 hours of pure heavy machinery heaven.

If they find something broken, better send it to Curtis at Cutting Edge Engineering Austrailia. :)

it was always relaxing watching those semi robotic welders

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 💔

Hats off to all the Men who keep society running smoothly and take pride in Their work. They do it for Their families.

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 chuckled at 1:22:20 when he said “as this heavy weight rolls off the scales”. I was like if that A320 is a heavy weight then I’m built like the rock.

finally a documentary on this topic and a nice fat juicy one too spark always delivers good content

Was a rigger for 10 years and now I'm old and in poor health, but I miss building and moving big iron

I worked with one of these in Denmark. We use em for unloading the coal out of the ships aswell.

Enjoyable film, shame it keeps jumping from one project to another then back, I would prefer to see a single project from start to finish. Very interesting all the same.

Shoutout to the mechanics and helpers who repair and maintain the Giant Machinery

When you literally just need to smell the oil to be able to tell which oil it is 😁

Good Ole Doug, Tha absolute best dam Operator I have ever seen!!!!

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.

Big Muskie has joined the conversation. I was at the bucket last weekend and it’s absolutely monstrous.

Longwall mining systems are VERY cool, the miners that run them have balls of titanium, no way I'd ever go under one of them!!!

Awesome job

Just dropped a part of the big excavator off in AZ pretty cool seeing the site and the actual size of the equipment

To think some of us feel like this while working on your car at home and live in the rust belt lol

I've built the reclaimer buckets for the wheel

Astounding heavy machinery innovations push the boundaries of possibility.

I worked as a machinist for LeTourneau. This is super cool.

These men are amazing. Ian is worth his weight in dark matter.

As a hydro guy, I feel the digger mechanics' pain. You go through a arduous task only to find it to be a simpler fix later.

I just love all the work these men . I think I never stop learning Thanks so mycu for this video...Granny U S A

2:19:08 I wish my company has group warmup activities like this.

Nice one. As a popular rally driver once told me in private (after he crashed and became a spectator) that he would rather race and come last than to stand on the side and watch the boys have all the fun.

Scaffolding is key..! To all my high flying scaffold brothers..who have families to feed 🤘🏽

He knows the dam damn well and is damn good at his dam job!

Wivenhoe dam. My backyard. My dad and two uncles worked on the building the dam and mum and dad bough a big property beside the dam.

Some skilled mechanics freeze the bolt and heat up the whole piece and is way easier to change the bolts

Now I can repair my Tonka trucks, great tutorial.

He's a damn engineer... Sounds Epic

weld lifting lugs on the base .much love and respect

I'm over here trying to figure out why farm sim 19 music is playing in my room and its this video lol

Hey hey y'all doing Happy New Years anyway anything to do with big mechanical machine you work like this or anything that nature I'm all for big trucks muscle cars anything that nature all for it you guys are awesome I like this kind of stuff thank you again for the content God bless you have a blessed day

Too many Ads! Really spoils the watching experience.

Shout out to Spark TV for keeping me entertained in county!

My dad would’ve loved this he was always watching things like this

Amazing, keep it up!

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

Excelente video!

This guy really enjoyed his time being able to say Dam over and over again. 😂

I like the pronunciation of schedule lol. Sedual

Teamwork makes the dream work

Good stuff.

0:37 Ooo, down under got baby Baggers!

We won't see adoption of this technology in my lifetime. Or, given that I'm 70, most everyone else as well.

Do those hydraulic roof supports not have a mechanical locking system in case of a hydraulic failure?

All this heavy repair is like dancing with a clumsy giant.

They are not Bolts, they are studs. (21:50) come on guys get it right, people watch this and pick up the incorrect information, also we work in metric not Imperial.

great images. like the commentary.

Why is there a TV show on RU-vid… it’s amazing😂

Wow. I felt good about working on my old John Deer.

“The dam wall” “As a dam operator” “Dam safety engineer”

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.

it's always doug and his team showing up

"With such a straight forward task, what could possibly go wrong?" C'mon man! You NEVER say something like that before any kind of project! (Yes, I know it was sarcasm)

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.

Realy I like this video so so much

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...

Very interesting. It just goes to show that engineers don't know everything. Great video.

I’m so high rn, I learned more off this than I have in school✌️

Damn boilermakers!

Thanks, Don and team. Next time I want to blow my kid's mind, I'll point out that they're moving at the speed of light.

COOL

I didn't know there's a wive'nhoe reservoir 🤷‍♂

Nice

Very lucrative business development

Is Tedious watching Constant switching videos from 1 project to another, increases length by 1/3 as each is reintroduced, just for more $.

I like technology and science

Love the “one bolt one shift” bullshit.

Right on. Smart girl. Never to young to learn gun safety she's definitely a talented shooter for her age. Awesome

“If you can’t fix it with a hammer . . . . you have an electrical problem” 💪😜👍🏻

The way you present your content is professional and easy to understand.

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.

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!

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 ,

The video does not do due justice to how HUGE these machines are. The Bucket on that Hitachi EX5500 is massive. It makes the operator look tiny.

LOL at "Engineers repair and maintain". I've never seen an engineer get his hands dirty

Cool to have a look behind the scenes of the country and the companies that lead the fight against the fight against climate change :D

At least they're not working in their flip flops sandals.

I am proud of you all

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

Equipment failure happened at Oroville Dam. So yes, it happens. Some people didn't do something.

He is the Dam operator, And he knows the gates Dam well

Rattle gun I always have called it impact

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.

Why didn't they weld the lifting point back on the long wall jack?

Jumpscared me with the blasting loud intro lol

If it don't fit the first time use a bigger hammer

dang look at all those over sized Tonka toys lol 🤣
