7800 DRAGLINE

[@DavidJones-gq1rs]

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.

[@kedricksmith8331]

What qualifications are needed to run a dragline

[@paulmiddleton4215]

just curious if it was in Perry county Illinois where your G-father was an oiler?

[@marctiltman9555]

A great video, and thank you for not ruining it with junk music. 😊

[@charlesanderson9277]

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.

These machines are incredible testaments of mechanical engineering. Many were designed only with human minds and hands. Humbling.

[@Healthliving1967]

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!

[@jolla9963]

And to think, someone calculated them, then applied them. Mankind can be truly wonderous when it wants.

[@BlackPill-pu4vi]

@@ah6414 They had mainframes to do mechanical stress studies and simulations. Regular everyday calculating was done by slide rule.

[@blauer2551]

Thanks for showing this, I’ve never seen one of the big ones doing anything but working with the bucket.

[@billhillyer334]

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

[@chatboss000]

Holy smokes, just now I realized that it kinds "leapfrogs" when "walking" instead of alternating between the 2 feet. Still super cool!!!

[@leesmavicmoments5598]

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 😂😂😂

[@chatboss000]

@@leesmavicmoments5598 well, maybe like those wind up toy robots with the broad feet that technically DO alternate legs.

[@lawrencedoliveiro9104]

It must be able to move just one foot at a time. Otherwise, how would it turn?

[@chatboss000]

@@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.

[@nodularification]

@@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.

[@tihspidtherekciltilc5469]

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.

[@dougaltolan3017]

It's not a fine balance, it tips towards the boom and drags the edge of the round foot.

[@timmayer8723]

I believe it takes 7700 volts to operate this monstrosity. The electric motors are the same type of traction motors used in diesel locomotives.

[@filthyphillyboy]

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.
