Inside a Marion 8700

A look inside a 1965 Marion 8700 walking dragline. Of the two machines built, this is the last operating 8700 in the world. Want to see more draglines? Subscribe and join PAmining today!

you are so lucky to see inside on of the machines, definitely amazing to see

[@rossfromfriends8468]

I’ve never been in a thing like this but somehow I can picture the smell. Grease and old metal

[@JackOSUrulz]

Near a town in West Mineral Kansas is a machine like this called Big Brutus, it's now a museum. I have seen it a few times, I believe it has a 160 foot boom. It's pretty amazing how big these machines are, when standing next one you feel so very insignificant, it almost paralyzes you in awe. Brutus was operated by Peabody coal mining. I had a video on an old vhs tape I bought back in the 90s showing them driving what appeared to be a 65 Chevy truck into the bucket.

[@doppler327]

JackOSUrulz i live about 40 minutes away from it, been there 5 or 6 times, truly incredible to see each time, i also had the VHS tape, awe inspiring for sure

[@Nightwing690]

Good lord, this thing looks like part machine part home, there's not just motors etc. inside there, there's workbenches, lockers, so much space, it's like a two story house, this thing looks like you could live inside it with a dozen other families. Absolutely unreal.

[@mackcraddock6927]

I have been around the big diggers since I was nine years old and I am 65 now have ran and worked on them from building to repair nice video some of the names of the motors was not what we used but still brought back memories

[@kresimirmilisa5560]

what people can built its amazing justin just amazing good video about this last walking dragline.

[@MarylandConstructionDiecast]

Great video. Thanks for taking the time to do these.

[@Brad772006]

Wow, I was thinking that inside the house right in the middle of the floor was one Briggs and Stratton 5HP motor. Just pull start it and dig away.

[@TheOlJWShow]

We want to see downstairs!!!' Waaaah!

[@zacharylew9537]

JESUS. its massive inside there. really gives you an idea of how massive this machine really is. theres a bed inside the cab too

[@HughieMunro]

Nice video man, the buzzing noise from them transformers is bloody scaryyy

[@Bomaz727]

Very nice look inside. And 85 yard bucket wow!

[@Godsglory777]

Interesting video. I rebuild those drums in a shop over in Mount Vernon IL (Lays Mining Service).

[@NikalaiVanLife]

I love big machines,good video

[@nodularification]

Thanks PAmining, your videos are the best. I like the broad range of equipment you have covered, some of it quite old and obscure. From what I gather, there has been a renaissance in anthracite mining (I have a geology degree)--what is driving this? What are the markets for this coal? I understand there are some niche uses for anthracite, titanium processing being one of them. I am familiar with the history of anthracite use as home heating fuel, but can you fill me in on current uses? Thanks!

[@PAmining]

Thanks! It is big!

[@fernandomurillo9272]

Pure awesome power one hell of a machine

[@robfraley4210]

Good tour..!!

[@PAmining]

And remember by dragline scale, this one's only mid-size!

[@Delirium386]

..this a really monster machines...very interesting video...thanks..

[@PAmining]

Thank you!

[@PAmining]

This is an electric machine, it doesn't run off diesel fuel.

[@PAmining]

Thank you

[@PAmining]

Thanks!

[@joshtaylor4249]

What a machine!

[@O7ROADKING]

cool video thanks for posting

[@4407intow]

Power company runs a sub station then they run a huge extension cord that must be moved around with a tractor I am in training right now for a smaller machine a 2355 with a 24 yard bucket and it requires 25,000 volts o f electricity can't wait to operate

[@camo15767]

i worked on this dragline in 2011

[@2001yz250rider1]

it would be awesome to get a view from the top of the boom!!

[@aaronballeck3153]

Great video. He kept saying "the shovel". I didnt see a shovel anywhere, only a dragline.

[@PAmining]

Around here it's very common for old timers to call draglines shovels.

[@RobertWilliams-mk8pl]

Incredible

[@drewclancy5174]

Right. Right. Right. Ok. Spins em. Ok. Gears and everything. Alright. Ok. Alright. Hoists. Ok. Is it loud? -Ready to drive it!

[@lozarok]

Great Vid... Good Work !!!

[@Lone-Wolf-66]

Sounds like a giant Bug Zapper... Be careful..! 🤭

[@loganbaileysfunwithtrains606]

I want a drag line so I could build rooms inside and make it a home

[@NORCOAIR]

Need on to dig my potatoes in Texas...they are big.

[@shawnhammack8479]

Its like bieng inside a big garage.

[@PAmining]

Your welcome

[@christanrathke5928]

@PA mining Is this dragline still in operation today?

[@herbgarratt]

Seems to be a Ward-Leonard (sp?) control system?

[@gilzor9376]

@3:52 . . .lol . . hilarious how the guy giving the tour answered with a pause and a drawn out "naaaaww" . . . . "couple million . . (inaudible) . . . . I did know once upon a time." Kinda sounded like Larry the Cable Guy lol . . . def not a numbers guy, neither am I on this stuff, but Google says 9.2 mil lbs, that's a lot of steel!

[@meandthemrs7403]

I'd like to know how many tons of copper are in that thing.

[@mightyjoe11722]

The gentleman that was giving you a tour of the machine gave away where in pa you guys are by the way he pronounced his letter h. Is this machine still working or was it retired since the video was made?

[@PAmining]

mightyjoe11722 Haha, only people from PA would recognize the accent! No this dragline is still in operation today

[@Mr.XJ.96]

+PAmining....I've seen 2 of these types of machines.. West Freedom and Calensburg PA near Parker. They are still there to this day...rusting away.

[@Atreid3s]

It's actually not, they run a power cable out to it.

[@wmden1]

I have a couple of questions that if somebody knows the answers, I would appreciate knowing. I assume the incoming line power is AC. I have heard the word generators used on a couple of these walk throughs. Do they use the AC to power motors that pull DC generators? If that is so, do they use DC to power the Hoist, Drag, Swing motors, etc. because speed control is easier with DC motors? Are the transformers, he referred to, used to step the incoming line voltage down to supply the AC motors?

[@NCOHDairyFarmer]

Actually it runs the generators with electric motors. If you were paying attention in the video you would have noticed that.

[@reallyslowcustom2514]

Hell Yeah

[@jeremylee99100]

bet it sucks when the motors run out or need repaired

[@scottdrillinginc]

It's electric, like a Prius.

[@pyalot]

Paige so that is what clean coal means ;). Does it also have the electrolytes the body craves?

[@SomeTechGuy666]

The electronics in that thing are ancient.

[@PAmining]

@lozarok Thanks!

[@redheadedduckhunter]

Should build small one room apartments in it.

[@Videogame-Matt]

basically big muskie mk2

[@zaxisontherun]

still smaller than Muskie though

[@PAmining]

No shit he's being sarcastic lol

[@Justinofalltrades1]

how much fuel does that thing burn?

[@JordanMotography]

but it does have to run the generators with diesel. so, it does run fuel to work. im sure it is alot of fuel!

[@jarredri]

No they bring 7200 volts ac from the utility company with a big cord

[@Smittyschannel]

BUT, what runs the electric motors? Its a self contained machine

[@jasinere35]

diesel generators run the power supply that in turn run the rest of the machine

[@rayg9069]

@@jasinere35 The generators are 'motor gen sets' They have electric motors powered by the trailing cable driving the generator, by changing the excitation to the generator they can alter the voltage supplied to the main traction motors. This machine was build before modern solid state high horsepower speed controllers were available. Old building lifts were controlled in a similar way, but much smaller.

[@scotttaylor8498]

Looks like your in warehouse not a earth digger lol
