My grandfather worked as an oiler on one of these for 30yrs retired. I remember as a young boy he would take me on board when it was runming. Walk thru the whole machine while it was digging and sitting in the operators cab. Very good memories as a youn man. Thanks for the video.
I've operated approximately 30 different models of walking draglines over 20+ years including a 7500 and a 7900 Marion , the 7500 had an 18 yd. Bucket and the 7900 had a 49 yd. Bucket with 275 ft. Boom . The 7500 was fun to run but the 7900 was like a Cadillac to me for operator comfort and a nice machine deck . The biggest i operated was the " Ace of Spades " Page 757 with a 65 yd. Bucket and 333FT BOOM sitting on a 75 ft. Tub in the FLORIDA PHOSPHATE MINES for approximately 10years out of the 20 + years I worked there .
Like a 3 story. 50,000 square foot building picking itself and moving 10 feet, or so, with every cycle. With all of the electric motors, winches cables and the frame and boom of the dragline, it is probably much heavier than that 3 story building. Amazing engineering and manufacturing processes for something this huge. Hat's off to all involved in building machines like this.
I could watch this thing in action all day long and not get tired of it. My jaw would be hanging open in awe, and I would be looking at every part with barely contained enthusiasm. No goofing around though, safety first always.
I ran drag line well electromagnetic one, scrap yard twelve years link belt, bucyrus Erie, American these were like two an a half yard buckets I forget the length of the boom but once you ran one size dus not matter... 👍 this is like a seven or eight yard bucket an the length was forty five foot boom this is way longer there fun to run though
@@lawrencedoliveiro9104 In the video you can see the entire machine rests on a round platform. That platform moves with the machine and lifts as the dragline "walks". There's no need to "turn while walking", it either turns to face the direction it needs to go or it walks forwards.
@@lawrencedoliveiro9104 Shoes are attached to the upper part. With shoes up, they just rotate and point the rear end in the desired direction of travel.
Yeah and there is an "extension cord" going all the way from the machine to its own substation! At least the Marion 8700, not far from this machine has/had its own substation.
I'm still trying to understand how it balances on the feet attachment points and would love a walk through tour of the inside as that's 4.5 houses big.
@Analog Human I've found the history of the one in South Wales. It's where I live and my grandad worked there driving the dump trucks for a company called lovetts. They nicknamed it oddball because it ran on different electricity
Nope! Marion was a company that produced many walking draglines before they were acquired by Bucyrus. This is a smaller model, believe it or not. The 8950 was the largest if I recall correctly.
The guy at 7:22 has such trust in the driver, who just has to push the wrong lever the wrong way for the whole machine to suddenly jump on him! Yikes! 😯

What qualifications are needed to run a dragline
just curious if it was in Perry county Illinois where your G-father was an oiler?
A great video, and thank you for not ruining it with junk music. 😊

Never seen a building change zip codes before !
Those pins and bearings would have to be incredibly strong to cope with the sheer weight of this beast. The stresses involved here are massive!
And to think, someone calculated them, then applied them.
Mankind can be truly wonderous when it wants.
@@ah6414 They had mainframes to do mechanical stress studies and simulations. Regular everyday calculating was done by slide rule.
These machines are incredible testaments of mechanical engineering. Many were designed only with human minds and hands. Humbling.
Thanks for showing this, I’ve never seen one of the big ones doing anything but working with the bucket.
An apartment building that moves it’s self.
Que projeto de Engenharia da Pôrra véi. Máquina Muito Louca.😮😮😮
In 1974 a Ransomes & Rapier W1400 walked 13 miles from one quarry to another for Corby steelworks in the UK
William Cowie an older one still stands in Jo's Nigeria and gradually people are vandalising it
How long did that take?

Yup,, this video cut just before a turn.
Do they stop and reorient, or turn on the fly.?
We will never know.

This is an amazing machine.. it's so huge!!😳😍WOW! I love these big giant heavy duty machines..and it's a Dragline. 💙💙💙💙😍😍👍So cool.
A motorized mountain of iron, steel and copper!
Holy smokes, just now I realized that it kinds "leapfrogs" when "walking" instead of alternating between the 2 feet. Still super cool!!!
What did you think it would walk like? Lol when I was younger I had a image of the at-at out of empire strikes back 😂😂😂
@@leesmavicmoments5598 well, maybe like those wind up toy robots with the broad feet that technically DO alternate legs.
It must be able to move just one foot at a time. Otherwise, how would it turn?

Pretty cool. I've understood the concept for a long time but its not a common occurrence to see. Thanks, bud!
Marion 7800 no Brasil tem uma unidade só. Muito bom vídeo ver ela se movendo esse colosso de ferro. 👍👍
That is an insane engineering feat.
That moves the same speed as my wife
That's funny except I got one too
Moves the same speed but does a lot at the same time
About the same weight as mine.
My wife hauled ass the other day and it took All of 5 trips 🤣😂
Might be similar in speed to NASA’s rocket transporter.
Amazing how the electric grid handled it.
At x2 speed it's more enjoyable.
When it moves it reminds me of a dog with an itchy butt
Look exactly like the units I worked around in Big Brown Coal Mine east Texas.
Hello, I am Hakan, I am a loader and excavator operator.
I'm looking for a job
I believe it takes 7700 volts to operate this monstrosity. The electric motors are the same type of traction motors used in diesel locomotives.
Yeah and there is an "extension cord" going all the way from the machine to its own substation! At least the Marion 8700, not far from this machine has/had its own substation.
So what is the back of these things if they are Electric?

Power system is 25kv incoming. Then converted to dc via the MG sets

Its all fun and games until your dragline walks away from you.
Thats it!!
Im building a walking house!
I’m hoping for one built on the carriage from an excavator, so I can crawl it across my neighbours front lawn.😂
I think if I layed under it just right,, it would pop my back into alignment and release Alot of tension and stress 👍
I wonder how often those pivots need repairing.
I'm still trying to understand how it balances on the feet attachment points and would love a walk through tour of the inside as that's 4.5 houses big.
It's not a fine balance, it tips towards the boom and drags the edge of the round foot.
Thats 8 hrs right there on the clock just walking it.
If this mine site was in Australia it would be shut down looking at the condition of that dragline.
Essa máquina é o máximo
Biggest walking crane!!!!!! The fucking awesome!!!
IT'S A DRAGLINE AND THIS 7800 IS VERY MUCH " A BABY " !
Is this the one that came to South Wales in the 50s
@Analog Human I've found the history of the one in South Wales. It's where I live and my grandad worked there driving the dump trucks for a company called lovetts. They nicknamed it oddball because it ran on different electricity
@@leesmavicmoments5598 That’s a weird name for your grandfather.
Just like a robot in a game: NieR - Automata

is that the first and still only produced walking machine ?
Nope! Marion was a company that produced many walking draglines before they were acquired by Bucyrus. This is a smaller model, believe it or not. The 8950 was the largest if I recall correctly.

Well honey what you do at work today I took an 8 Hour walk with the boss
Yeah that's the Crane that's in Freeland Pennsylvania pretty sure
What's the purpose of the water?
Help it slide easier.
It gets thristy
It would take all day to move 100 yards at that pace.
I work with some people who are the same 👌👍
