I was working at Peabody's Dugger Mine during the 70's. We had only one dragline, but it was the biggest in the world when it was erected in 1968. It was painted yellow and green. If you watched red a gray draglines, they belonged to Amax Coal Co. and my brother and father worked there.
I wish I would've had the time to see these things back then. I remember all three working way out in the distance when going to Freeland the "back way".
pmc eightsixeighty Draglines are designed to dig from ground level down and shovels are designed to dig from ground level up. So shovels sit down in the pit and dig up where there isn't a lot of room for maneuvering, especially sideways. So the crawlers on a shovel turn independently from the swing deck and they have large hydraulic jacks built into them to keep the shovel level.
Draglines also could move quite a bit more earth then the power shovels, which mostly were good for very hard rock faces and other tough to get at seams. Of course, bucket wheel excavators pretty much trumped the truly big power shovels, which is why they're now an extinct breed.
The good points of a dragline. They could put the dirt higher and farther away compared to a shovel. And for that reason, they could dig deeper and handle a lot of mud. The bad points of a dragline. You had to build road for a dragline, which resulted in re-handling material that resulted in time not stripping the dirt off the coal. You had to blast the rock better for a dragline. The good points of a shovel, you didn't have to build road for a shovel because it sat on the coal and you didn't have to blast as well. The bad points of a shovel. You couldn't dig as deep compared to a dragline because you couldn't get rid of the dirt and you couldn't handle much mud. As for a wheel excavator. A wheel excavator can't handle rock or mud.
The boom on a dragline may help the dragline walk somewhat better, but a dragline will walk just fine without a boom. The walking cam is deliberately placed towards the rear of the machine to pickup the back of the tub and drag the front of the tub. When draglines are moved on a river, they dig a canal for a barge, place the barge in the canal and then sink the barge. Then the dragline, without a boom walks onto the barge. Then the water is pumped out of the barge.
Another great video showing us things we would not have ever seen otherwise. Thanks
I use to watch these things"walk" around the strip mines at Dugger Indiana in the 70s. What a way to spend the afternoon.

Faster then watching the grass grow 🪴
I used to ride my motorcycle and climb the high walls in the Peabody strip mines when we we're growing up in Boonville Southern In

What a beast of a machine. Oh how I love working and building BIG. These machines make the ships engines I machined look like dinky toys, LOL.
This video would be meaningless without sound ! What a cool beast !
Keep em coming Walt.
@Slimdor It's because it really isnt that big compared to other draglines!! (but its big!!)
Has there ever been mishaps with those moving or "walking"? Like a foot completely stops, or the entire machine tipped?
cool video, would like to see the electrical hook up, must be one hell of a drop cord. thanks for posting.👍👍
Shoes contractor Addidas: Just Dig It.
Looked like it was getting a little too close to the edge of the drop off to suit me. I hope it was solid.
Looks a bit like me learning to line dance.
i like to move it move it we like to move it move it
Hey boss...just a minute...I got a rock in one of my shoes.
The "Anthracite" king?
Listen to it groan
Wild looking dragline , a Page is it ?
That's a Bucyrus Erie 1250.
Cheers mate
Einfach gewaltig! 😯
Where is this machine located
It was and might still be near Hazleton, PA. I cant remember off hand if this machine was retired or not. I grew up watching it work and walk around.
@@josephrichardson9662 It's still sitting on Stockton Mountain just outside of Hazelton. It is not in operation
@@richardjoseph8683 thank you.
@@josephrichardson9662
Thanks as well!
So what happens if it gets stuck ? Say the dirt the shoes sit on sinks deeper than what the lift distance is ?
Then you’re screwed
Lift the shoe and shovel shit under it.
I always wondered why no one made a walking power shovel.

Yeah, you would not want one of those pads to step on your foot...:) Sick ass physics and amazing feat moving all that weight!
+godbluffvdgg--- Amazing feat...feet...feat.. get it? Hardy har har!
Harlarious!
You should see when I make an “adjustment or movement”. 😂😂😂this big ole machine is nothing compared to that
