    Man they keep the old girl looking good. Inside and out. Draglines are way cool. Makes those little 3/4 yard machines I used to operate look very insignificant. Thanks Aaron for doing what you do. For an old gear head it's fun to watch. Cheers

    Awesome video. As a retired heavy equipment operator i don't think i would last long doing that unless the pay was real good. After running a excavator for years loading on and off road trucks this would make my brain rot fast .The boredom is hard to overcome. And the machine actually runs on coal , because without coal .... theres no electricity.

    Well thank you for this video. For many years my Company (Monitek) performed vibration analysis on these machines in coal mines throughout Australia, the purpose being to detect the early warning signs of wear (defects) in the many large bearings and gears driving them, thus allowing corrective maintenance to be performed before a catastrophic and very expensive failure occured. One of our employees later emigrated to the USA and set up a sister company in Wyoming to service the coal mines in the region. Never thought I would see this sort of detail on TH-cam.

      Yeah... I think the OP may be tilting at windmills. (Almost literally: they kinda teed that up, eh?)
      Energy is energy, and, sure, there is the intermittancy issue with wind, but there are solutions like pumped hydro, etc for that. Installed wind power is already less expensive than any source other than, in some marginal situations, natural gas or coal- and the gap is closing fast! (It would already be closed except for the absurdly massive fossil fuel incentives, favroable interest rates, tax breaks, and immunity for the environmental damage they cause, etc, etc.)

    I often do maintenance shutdowns on 1350 and 8750 draglines in the Australian Bowen Basin. As amazing as they are to see and experience first hand, once you experience pulling them apart and fixing them, they get old very fast 😂
    Edit: To further explain your explanation on how the machine swings, the motors you mentioned in the front of the machine sit on a vertical axis and connect to the swing shaft (think of a driveshaft in your car), on the bottom of the swing shaft is a cassette (a big cog) and the cassette rotates along what is called the slew ring which is a very large gear ring. To put it simply, the swing shafts spin the cassettes along the slew ring which in turn rotates the dragline. The size of the dragline also dictates how many swing shafts the machine has. For example the one in the video would have 4, a larger machine might have 7. The Machine in the video is also just a little baby dragline.

      23KV running through that cable.

      @arvbergstedt3303 7 หลายเดือนก่อน +5

      Called 23 kv Cable. Actually 22,900 volts. Portable substation hooked to 69,000 high line. Goes into dragline to 4160 volt transformers which feed 4-3000 hp motors which drive a bunch of dc generators which feed the dc motors.

    I'm curious what the amount of power it takes to run and compared to how much coal it digs. It's always interesting to think about the economies of scale with big equipment. I'd love to see real data on comparisons.

    Correct me if I’m wrong but isn’t Bucyrus-Erie the very first to design engineer and manufacture drag lines in the world starting in the late 1800’s?
    How often do they have to change out the cables due to fatigue and stress and do they have to be certified and inspected by OSHA like cables on large cranes?

    • @helloitsjason
      @helloitsjason 7 หลายเดือนก่อน +4

      Its hard to say. Page Engineering (John Page) were the first to make draglines. Both Bucyrus-Erie (now a part of CAT) and Harnischfeger (aka Pawling & Harnischfeger, later P&H Mining -> Joy Global -> Komatsu Mining) got into the dragline business in the early 1900s both operating out of Milwaukee. Neither were the first to make them, and those two companies went head to head for many years in the business, and pretty much bought out all the other smaller firms (for instance Page Engineering was bought by P&H in the 1980s). Nowadays most draglines are just maintained, and new ones haven't been built for quite some time since its easier and cheaper to maintain existing ones and replace them with rope shovels if they are no longer suited for an application.
      I work for one of those companies and can't say exactly how often cables are replaced especially since its heavily dependent on the work that the dragline is doing and where, however I can say pretty much everything that goes onto a mine site is inspected by MSHA at least once per year. MSHA is the mine specific version of OSHA. MSHA controls mining and quarrying exclusively, while OSHA controls pretty much anything else, including things like maintenance and repair shops that might be on mine sites.
