I am a welder and machinist for Lays Mining Service in southern IL. We rebuild the drums and sheaves that drag and help guide those cables in ans to allow that bucket to do what it does. It's just interesting to see those draglines in operation.
Very nice Vid...! I thought drag lines were a thing of the past... Great views of various parts of the "mechanics" and operation of this, apparently, new machine.... REALLY enjoyed it...! Thanks for posting! Gordon
They are built in the state of vorarlberg (Austria) and are fully hydrostatic operated, so they dont use clutches and other parts that cause a lot of wear.
this is more a duty cycle crane type dragline and nothing close to larger B&H draglines now made by Caterpillar, the 8750, which requires assembly on-site
As far as I knew from working for Komatsu/P&H, Draglines these days were just huge open-cut machines 3-9,000 tonnes, didn't really know there were still crawler cranes set up as small draglines.
I bet that baby's really comfortable after running the ol northwest I have insley draglines and am running a American 195 right now keep up the dragline videos 👍🏻the 8100 Seams to be a real sweetheart
Are modern draglines set up at all such that you can have them running semi-automatically for a small fixed position for the unload? By that, I mean still with direct operator control for the load sequence, but once the bucket is filled, the operator can just set it to reel it up to the pre-programmed height and have the unload go to the exact same spot, as it does here, but with a computer running that part of the sequence. I would think that having roughly half of the cycle handled that way could put less wear on the machine, get productivity much better, get the unload better located, and fatigue the operator significantly less.
PinkOld I wish that I could say yes but it does not. maybe liebeherr could work on this for future software updates, that would be such a great feature to have especially with these computer control machines. with as many electronics this machine has it would be an easy feature you would think? we have thought the same thing how nice that would be.
That was quite a Machine, and very good operator, use to run an old northwest 80, an a 8, running that machine the guy was really fast and on the money, really enjoyed it 👍🙄
Great video. You have some excellent equipment. That crushing plant seems to be dialled in perfectly. I've spent some time in Des Moines almost 10 years ago. Iowa is a beautiful state with really nice people.
Pretty neat little machine, Although i would be a little hesitant about being positioned on the edge of a 3 - 4 meter vertical face with unconsolidated material as support - that could end up very costly.
@@stnicholas54 I know a guy who nearly dropped a PC490 off a 25' bench because he was mining with his tracks parallel to the face. Also unconsolidated material.
Soft landing there chuck...he's not bouncing it off granite boulders.....He could take the swing out of it a bit better so as to have the bucket land square, without slowing his tonnage/per day....
Also did you read the comments at this machine is brand new when this video is taken? And that giant delay from when it lands from when he starts dragging the bucket in was a computer problem which wouldn't let you drag the bucket untill it let you... That has since been fixed. In retrospect I probably should have never posted this video until he had the hydraulic brakes all electronic machine figured out better they're obviously allot different than the old Northwest mechanical drag lines. We had before.
I am a retired operator of 40 years, have run both types of machines friction and hydraulic, by far the hydraulic is much easier to operate . I have replaced operators that did the very same thing this guy is doing, they were "Replaced for breaking up the bucket"! The bucket can only take that for so long. He should be "eating his lunch on the way home" ! Must be the owner!
Don't you have any thing better to do than comment on the same video that you already commented on from 4 years ago... By the way we are still using the same bucket from 4 years ago.... But I'm sure I'll see another comment from you saying the operator needs fired because you think he still operates the machine as he did 4 years ago. And something about the poor poor bucket that were still using because it still hasn't broke..... My God people!
I'm pretty sure dropping a bucket on sand isn't gonna hurt it for all you peole who are affraid of the bucket breaking. Give the operator a break. Everyone that drives a strange vehicle it takes time to learn how to. If he was such a bad operator he wouldn't be able to keep up with the plant he is feeding. I know I have worked around sand and gravel plants.
Hell, I'm not even an operator and I could see that he was badly abusing the whole rig, cables, pulleys, bucket, chains, even the boom, doing that stupid high speed drop.
There is as much as a 5 second pause from the time the bucket “crashes” until all the slack is taken out of the dump line and so forth and digging resumes. Beginners always do this. You can avoid this even when casting to the outer range of the machine. The technique must be carefully developed over time to avoid risk of damaging the machine. It is subtle, but quick, smooth, and a “next level” sort of thing. Dropping the spreader bar on the bucket is absolutely unnecessary unless you are digging underwater and can’t help it. Problems with casting technique can be identified from the moment the bucket was emptied that I will not get into. This pit clearly has one of those special cultures.
Drew Hall yes I did replace the northwest not this current one though the one sitting next to it is a model 6 the one who replaced was a Model 95 WT around a three and a half yard machine
He's moving more then you think. Has filling a tri axle dump truck every two to four swings depending on dump body of the truck. The large size of the crane just makes that bucket look small.
it's pretty easy to criticise from your keyboard fellas. remember this is a brand-new machine with hardly any hours on this is much different from the old Northwest that was ran for years. Also he could run much smother but that means he would slower . which means allot less tons per day which you guessed it much less money in the bank a day. not sure about you guys but we'll take the money in the bank vs being a little easier on the old cheap bucket which I might add we have never had bucket problems. cause it's being tossed into sand.
Ya but slamming that bucket like that is uncalled for and really hard on the machine, none of the dragline operators do that where i work or our drags would be worn out
Anna Bortion machine now has 2500 hours only problem we have had with it is from the def system which is not related to tossing the bucket around which we still have not had any problems with.
It won’t hurt that bucket to slap the ground here and there, some landing were harder then others but he definitely had the touch where it counted and that was getting material into the feeder and not all over the ground around it. He could use to float the bucket a bit more and not bog the crowder winch so much. And lower bucket returning to cut a bit sooner and slower to save on the spool brake
He wouldn’t last one shift in a coal strip operation. You go replace that point sheeve because he lets his hoist rope pull to the side, and the shock to the machine by dropping the bucket. Must be related to the owner.
If you were thinking that he's a poor skilled operator for dropping the bucket like that then you are wrong.He is doing so to reach further from the machine.Also,the bucket is perfectly fine, it's not being dropped on rocks.
You mean that a person who spends about 2,000 hours a year operating a piece of equipment might actually know more about it than the self-appointed Internet experts? Well...that's disappointing isn't it...
Why should he cast that bucket, and beat the shit out of the rigging, when there is a dozer sitting down below who could push that shit up to him, think again asshole I ran a 2570BE and know about the abuse the rigging takes sand or rock!!
You are wrong, he is either unskilled or just don’t care. He has not been on this machine very long ,I know because the spreader bar is not bent like a horseshoe!
I appreciate everyones perspective. Everything looks different in the seat. I like watching big things dig. Dozer hand for 45 yrs but i dont anything about running a dragline. Sure like to see em work tho
Yep, it’s like someone buying a lambo, but then only driving it 25mph in a 55mph zone everywhere they go. Same thoughts here with this machine, if your gonna spend that much money on a machine that powerful, use the power
This is awesome, have a little experience running an old link belt. Here in southern nh , not many places you can use those anymore. That thing musta been huge money
Wow, never seen anything like it 🙄 My first thought is keep that stuff Over in Europe where it’s made and give me a Lima, Manitowoc or a Bucyrus-Erie...!!
I have watched about 5 videos like this now, so I consider myself highly skilled. It's amazing what you learn just from watching a few videos on your phone. From my multiple videos of experience I'm sure I could run that machine better than that guy.
I used to haul a lot of Liebherr equipment out of the Leibherr facility in Newport News, Virginia. They shut down the I 264 tunnel for super-loads and you have to wait to escape the area. Leibherr has a huge quarry truck, I moved to Arizona in pieces.
Dont worry they break that bucket ill build them a brand new one. I build 5 to 10 of those things every year. Besides that its just a little bucket, im currently building a 120 cubic yard one now.

I never understood how does this dhovel work,on which pathent? Is it on the gravity? How does it hold in carry position and then just starts to dump and not dumping it before while swinging around?
I was thinking to myself "They actually make these like they used to", of course albeit with modern hydraulics and hygrostats instead of disc and shoe clutches :P
Friend of mine got a job years ago running a stationary dragline, pulling sand/gravel out of water. He had to work the odd Saturday. I went over once to visit. The draglines used an old 6v-92 for the power, so it was pretty loud with that thing screaming beside you all day. He made (at the time) $14-something an hour to pull levers and stomp a pedal, which was good money back then. They had a guy move up to loader-op or something, my buddy asked me if I wanted a job running the other dragline. I declined. Boring as hell, I didn't want to fall asleep and yank the opposing anchors out of the ground or worse, yank the dragline into the drink.
thats really nice sand and throwing the bucket in its sand cant criticize unless it was limestone or rock I thought he was kicking it and that baby wont look that new in 6 months in that kind of weather

I'm a crane operator and that is essentially a crane I don't know how the hell he keeps his line from turning into a bird's nest when it's slams into the ground in freefall. I have much to learn
Digging depth and radius an excavator would never be able to compete with a dragline without taking layers. this way the gravel can be mixed top to bottom.
I had no idea dirt of any kind in Iowa could buy a nice new machine like that!!! Congrats operator! See the old trusty northwest in background n what an upgrade!!! Thank you fer posting stuff that I’m interested in! Cheers from Northern California
@@Tomhellyer Totally agree. At first it's a buzz operating ADTs and excavators, but after a few years, especially on big bulk muck shifts it just becomes mind numbingly boring. Load at point A, tip at point B for a 12 hour shift six or seven days a week.
erichansen82 it is a wonderful machine we have had lots of problems with the def but if you want to buy a new one you better get ready to Pony up a lot more and 700k
I wonder what the Earth will look like 100 years from now, aftter we have stripped out all the stuff "we want", after we burn all the oil, and scrape all the animals out of the ocean?
