I have made the cages housing the brake rotors you see in 7:29 and it's cnc milled then welded together and bolted to the hub. Also the rotors are 2m in diameter and weigh just under 100kg.
Awesome video. As a retired heavy equipment operator i don't think i would last long doing that unless the pay was real good.

Indeed, I quit cnc operations for same reason. Most boring job ever just watching it work all day twiddling my thumbs and looking at clock every 15 min hoping an hour had passed.
1:54 That machine is 106 days short of operating 10,000 days. The most custom piece besides the bucket is the drive gear. I wonder how many individual sections it was cast in and if any of the sections of drive gear have been replaced.
@@tristenklein225 not sure about the dragline. I’ve built rope shovels it takes about 3 months to finish a Bucyrus 495HR2 rope shovel. So I’ll assume the dragline might be 6 months or more depending with the location where you build it.
Two years ago they replaced the tub on this exact dragline I believe. If not this one it was one of the other two at this same mine. ua-cam.com/video/ACrTGwEqxHQ/v-deo.htmlsi=4TofasCwqrvmAsyQ

That's about all I can tell you and be pretty sure about it.
These draglines are absolute beasts! 🦖 It's wild to see how they move so much earth with just one scoop. How much weight can they actually lift at once? I’d love to know more about their mechanics! 🤔
Former coal mine electrician here in Texas, , had 3 8200 and 1 8750, before going to work for Drives and Control Services,doing the electrical systems/ troubleshooting call-outs for over 6 years: they are the most awesome, unique machines ever I'm blessed to have worked on them for 13 years. Sure do miss it! Wonderful video and thank you!!!!
This is such a cool video. I worked for a heavy engineering company in Australia in the 70's called Perry Engineering. I operated a Skoda horizontal floor borer that machined the gear boxes and swing shafts for draglines.
Great Video!... My Grandfather on my Daddy's Side of the Family worked for a Company here in Pennsylvania called Highway Equipment... Before he passed away back in the late 1970's, He worked on Big Bucyrus Erie Machinery... He also had a Weld Shop... The sheer size of some of those Old Shovels and Draglines is just totally overwhelming!... This Kid does a good Job with these Videos... I enjoy watching this stuff... I've been in Heavy Equipment Business my entire life... Over 32 years, I'm pushing 50 now... And I learn something new every day about this type of stuff.... Like I said, Great Video!...
My father ran a drainage earth moving business and operated draglines, not like the size of this beauty of course. A dragline was one of the most difficult earth moving machines I've ever had to learn how to operate, my father could make a dragline sing, they were an awesome machine in there day and still have there uses even today. Cheers for the great reel.
Awesome video brought back alot of good memories i got to run a drag line half that size at a limestone quarry in central Illinois that my dad worked at when i was a freshman in highschool it was an awesome experience
Well you sort of got one thing wrong. I guess they didn't tell you, that if you were standing on the very end of the boom, when its swinging you'd be travelling between 60 - 80 miles per hour !!! Thats pretty damn fast for an earth moving machine!
@@joshkuhn3974 oh yes that would be right. I'm Canadian and it's 60-80 km/hr. They tested the ones up at Syncrude back when they had them. It's still pretty darn fast!
One stupid question but what exactly does the machine in this case do? It just looks to me that it moves material (coal?) from a to b, with b not being a dump truck or plant or so..
They create a moving trench … ahead is ground with coal under it, the trench is dug to expose the coal so it can be mined, and they use what they dig to fill in behind them where the ground is graded and the land restored.
I run a power plant and monitor our 3 wind farms. Yeah the wind doesn’t blow all the time. Especially on the coldest of nights. No wind no power. I’m grateful for the coal and natural gas power generation! My hats off to those who work in that cold up north.
@@titaniummechanism3214 Yeah... I think the OP may be tilting at windmills. (Almost literally: they kinda teed that up, eh?) Energy is energy, and, sure, there is the intermittancy issue with wind, but there are solutions like pumped hydro, etc for that. Installed wind power is already less expensive than any source other than, in some marginal situations, natural gas or coal- and the gap is closing fast! (It would already be closed except for the absurdly massive fossil fuel incentives, favroable interest rates, tax breaks, and immunity for the environmental damage they cause, etc, etc.)
I was lucky enough to not only get to see one of these in person but the guy knew the driver so he stopped the machine and let us onboard. The sensation of being in the cab while its swinging around and throwing its bucket is wild. So much weight
Correct me if I’m wrong but isn’t Bucyrus-Erie the very first to design engineer and manufacture drag lines in the world starting in the late 1800’s? How often do they have to change out the cables due to fatigue and stress and do they have to be certified and inspected by OSHA like cables on large cranes?
Its hard to say. Page Engineering (John Page) were the first to make draglines. Both Bucyrus-Erie (now a part of CAT) and Harnischfeger (aka Pawling & Harnischfeger, later P&H Mining -> Joy Global -> Komatsu Mining) got into the dragline business in the early 1900s both operating out of Milwaukee. Neither were the first to make them, and those two companies went head to head for many years in the business, and pretty much bought out all the other smaller firms (for instance Page Engineering was bought by P&H in the 1980s). Nowadays most draglines are just maintained, and new ones haven't been built for quite some time since its easier and cheaper to maintain existing ones and replace them with rope shovels if they are no longer suited for an application. I work for one of those companies and can't say exactly how often cables are replaced especially since its heavily dependent on the work that the dragline is doing and where, however I can say pretty much everything that goes onto a mine site is inspected by MSHA at least once per year. MSHA is the mine specific version of OSHA. MSHA controls mining and quarrying exclusively, while OSHA controls pretty much anything else, including things like maintenance and repair shops that might be on mine sites.
Cool and big machine. But what i dont understand.. why is the bucket so small compared to the size of the machine? Could the bucket not be alot bigger?
A bucket load of dirt weighs over 600,000 lbs. The boom is 300 ft long. If you figure in the forces it takes to lift that and how fast the dragline does it.. no it couldn’t be a lot bigger. Also the machine is moving over 500 loads in a 12 hour shift.
@@pupupupu448 Yes, but the question is how many times? Remember this machine is cycling over 1000 loads a day. The boom and other structure are still only rated for a certain amount, and steel fatigues with use. Every year there are cracks repaired and welded on the boom and frame structure.
Back in the late '60's we were fishing near the open pit coal mines around Wilmington IL. There was an immense dragline there, and we were invited to tour the machine. My father drove our Plymouth station wagon into the scoop of the dragline and there was enough room for another station wagon next to our car.
Hello i'm from the biggest production indonesian coal mining " berau coal ". I always watch your videos and fantastic experience about coal mining in the europe one day i would like to works there are
It doesn't matter how many times I watch videos like this on massive mining machines I'm still totally gob smacked and amazed by these huge masterpieces, and huge amounts of respect to America and the guy's who operates these giants because America is never out done when it comes to massive mining machines ❤❤🎉🎉🎉🎉🎉🎉🎉
Thanks for the video. Interesting! Three other questions: 1) Do the booms move? 2) how much does this machine weigh? 3) How much does this machine cost?
Wow that’s impressive 53 year old from the Uk here, when I was a kid my surrounding areas were open cast mining for coal up to mid 90’s Can remember going to watch a drag line going across a road from one site to another ( Marion I think it was called) We have non now and last last coal powered station has just closed We the uk are nuts Keep up the good work
son unas máquinas fantásticas, y más en sus mantenimientos, en el balde, cambios de cables y pines, en el boom y ni se diga en las partes internas, revolfren y Center pin, en los zapatos, toda una locura realizar trabajos de soldadura en esa areas.
Called 23 kv Cable. Actually 22,900 volts. Portable substation hooked to 69,000 high line. Goes into dragline to 4160 volt transformers which feed 4-3000 hp motors which drive a bunch of dc generators which feed the dc motors.
I often do maintenance shutdowns on 1350 and 8750 draglines in the Australian Bowen Basin. As amazing as they are to see and experience first hand, once you experience pulling them apart and fixing them, they get old very fast 😂 Edit: To further explain your explanation on how the machine swings, the motors you mentioned in the front of the machine sit on a vertical axis and connect to the swing shaft (think of a driveshaft in your car), on the bottom of the swing shaft is a cassette (a big cog) and the cassette rotates along what is called the slew ring which is a very large gear ring. To put it simply, the swing shafts spin the cassettes along the slew ring which in turn rotates the dragline. The size of the dragline also dictates how many swing shafts the machine has. For example the one in the video would have 4, a larger machine might have 7. The Machine in the video is also just a little baby dragline.
This old retired "sparky" helped rewire a few draglines in the Bowen Basin in the early 2000's. Dust , grease and noisy for sure ,but the money was good and a great bunch of workmates. With a few notable exceptions.😉🇦🇺
Well thank you for this video. For many years my Company (Monitek) performed vibration analysis on these machines in coal mines throughout Australia, the purpose being to detect the early warning signs of wear (defects) in the many large bearings and gears driving them, thus allowing corrective maintenance to be performed before a catastrophic and very expensive failure occured. One of our employees later emigrated to the USA and set up a sister company in Wyoming to service the coal mines in the region. Never thought I would see this sort of detail on UA-cam.
yeah there are more than two for each machine. Typically 4-5 total per machine. I think each crew technically works on average about half the year. It's a good gig
A mate of mine who is a welder told me that when the drag lines moved position in Mt Isa Australia, the entire town's electrical supply would 'brown out' as it did so.....
What a remarkable machine! Its crazy that at the make of this video this machine had 237,446 hours..... to put that into perspective that is 27 years. Mind blowing...
I got to see that exact machine operate a few years back when doing maintenance at their mine. I still see it once in awhile when traveling through there
On ironplanet they sold one of those Bucyrus Erie 2570W for 4,000,000 dollars but it was not sold because no one made an offer although you can still see the photos but it can no longer be offered.
I'm curious what the amount of power it takes to run and compared to how much coal it digs. It's always interesting to think about the economies of scale with big equipment. I'd love to see real data on comparisons.
Something i always wondered (also with our huge buckewheel ones here in germany) is how they are build in the first place, because good gods these things are MASSIVE
Have a look at how a fair ground Ferris wheel is moved around on a truck in pieces. It’s basically the same but the pieces are the size where one piece fits on a truck. That is to say the largest piece is 42 tonnes for over the road transport
Lots and lots of truckloads, then assembled in place. It’s basically a building with moving parts. The really heavy stuff that can’t be broken down gets hauled by special trucks with many wheels.
Man they keep the old girl looking good. Inside and out. Draglines are way cool. Makes those little 3/4 yard machines I used to operate look very insignificant. Thanks Aaron for doing what you do. For an old gear head it's fun to watch. Cheers

What kind of steel do they use to plate the bucket?
Its pacific rim in real life! Very cool. I always loved books about super heavy equipment
How many crews are there to rotate through the twelve hour shifts? I have to assume that it is more than two crews.
yeah there are more than two for each machine. Typically 4-5 total per machine. I think each crew technically works on average about half the year. It's a good gig
@@AaronWitt Sounds good, thank you.
Shame they don't make 'em as big as Big Muskie anymore.
Amazing machine
Great video aaron❤️
Your best video to date 🎉
Thanks mate
Woww.... Amazing
Great video
I love drag lines
Working on a floating (3m^3) grab dredge everyting seemed big to me on my machine... and then I see this ;)
I operated draglines for almost twenty years best job I ever had 💪
Up here they walked "The Anthracite King" some crazy distances, Some of it to do the cut for RT 81
That’s one of my favorites…im in eastern Ky
A mate of mine who is a welder told me that when the drag lines moved position in Mt Isa Australia, the entire town's electrical supply would 'brown out' as it did so.....
That's really nice they Gave you tour and a great one at that great team to do that thanks crew pritty amazing men to go above beyond
Awesome video, such a cool machine.
Its crazy that this machine is pretty much like a building that moves. These machines are insane feats of engineering
What a remarkable machine! Its crazy that at the make of this video this machine had 237,446 hours..... to put that into perspective that is 27 years. Mind blowing...
Wow. Incredible
Love ur videos bro keep it up 💯
Thanks for watching
I got to see that exact machine operate a few years back when doing maintenance at their mine. I still see it once in awhile when traveling through there
Very interesting machine ,thank you for showing us the work of those important people.
With out the crane how world you change the lines out? Or anything ? Tug boats have cranes inside ER
An engineering marvel.
On ironplanet they sold one of those Bucyrus Erie 2570W for 4,000,000 dollars but it was not sold because no one made an offer although you can still see the photos but it can no longer be offered.
I'm curious what the amount of power it takes to run and compared to how much coal it digs. It's always interesting to think about the economies of scale with big equipment. I'd love to see real data on comparisons.
the extension cord didn’t look That big, maybe 220v 60 amps.😉
It doesn’t dig any coal.
It's like a warehouse with extra functions. When you're a piece of equipment has a kitchen in it you know it's big
One hundred yards per scoop is about five (18- wheeler) semi-truck loads.
Started with 105 yd rebuildable buckets back in early 80s. Changed to 115 yard throw away lighter buckets. Don’t know what they’re using now.
These buckets now are close to 130 yards.
Bellissimo video complimenti 👍👍👍👍
Really enjoyed that video Aaron.bit differant to the volvo ecr25 I run in the uk
Thanks! That's Cool..
Honestly with how big they are, i teally did expect the bucket to be bigger.
Not many? Gotta be more than 50 in australia i think. Thats heaps.
I could watch that machine walks around all day
Big toy for big boy are very impressive machine to watch, thanks for the video.
thanks for watching
Curious how many kwh that thing uses in a day now that im not thinking how many gallons...
3:07 insane, it's so close to the edge like that?
Serious machine. Really enjoyed it.
I would love to see how they are manufactured and assembled on site.
Great narration & info thank you for the content 😎
A little to close to the Edge !
Any 45 degrees calculation in sight?
Something i always wondered (also with our huge buckewheel ones here in germany) is how they are build in the first place, because good gods these things are MASSIVE
Have a look at how a fair ground Ferris wheel is moved around on a truck in pieces. It’s basically the same but the pieces are the size where one piece fits on a truck.
That is to say the largest piece is 42 tonnes for over the road transport
Lots and lots of truckloads, then assembled in place. It’s basically a building with moving parts. The really heavy stuff that can’t be broken down gets hauled by special trucks with many wheels.
