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.
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'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 .
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.
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.
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

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.
Ну был прецендент на 120 км шагал. При ссср помоему.. затратил меньше времени чем демонтаж и потом сборка. Было видео😂 кабель и где то на горизонте эксковатор😂
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! 😯
