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.
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
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 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.
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!
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.
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
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.
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
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 👍🙄
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
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
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.
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.
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.
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.
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.
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
@@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.
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!
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...!!
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
My Dad run dragline for years, always "threw" the bucket. It's called casting, and one does it to get farther from the machine so you don't have to move the machine during the day.
Infandous Ktenology the machine only had around 50 hours on it during the making of this video it now has close to 2,500 hours on it obviously the operator is a little bit more used to the machine now we still have had zero problems with the machine and or bucket. I still don't understand why there's so much hate when there is no problems being made to the machine and or bucket. But obviously everybody gets a keyboard and they get really tough and how awesome they are at life. but I will agree if you are casting more than likely you do not have enough boom but in this case we decided to run the bigger bucket with shorter Boom for more productivity which means tossing it out little further to get the depths we were trying to achieve. I will try to get some time to upload a new video and how the operator works now since there is so much hate on this one but hey I guess everybody knows how to run a brand-new dragline in the first 50 hours that is completely electronic controlled and completely different than an old manual dragline.
rambo38505 I think you’re doing just fine! I’ve seen the videos of you guys running the old NW. Could tell you didn’t need any coaching at all. Don’t let those jealous dragline operator wannabes get to ya!
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.
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 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?
When I was in college I worked around an ancient BE 7W walking dragline in NE Minnesota. This looks so much smoother, quieter, and more civilized. I'm surprised you don't strip off the rocky top layer before you start into the sand.

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.
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.
My grandfather used to have a couple of drag lines for his gravel pit operation near Charles City. I remember riding in one once when I was a kid…but cannot tell you anything about it. I do know you don’t want to park them on the edge when heavy rains are coming!
this is not as large as built on site like the Cat 8750 dragline, it is a duty cycle crane built for production capacity and thus can be partly disassembled and transported in two or three transports
You would need a really really big long reach to move the same amount of material as this. we are currently using a 6yd bucket moving material from 45ft deep with a somewhat larger radius than Long reach could reach. On a good day if our crusher don't break down we can move up to 10,000 tons a day. The size of a long reach you would need to compare to this dragline I would imagine would be way too big to move from site to site.... We are portable operation that usually moves seven times or more a year
Thanks for reply looked like soft enough material you could put large size bucket on a trackhoe and the speed of the machine might make it worth while but cool to see dragline in action
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
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.

Good Equipment 👍 Good Operator 👍
The amount of abuse the equipment takes is amazing. I've repaired a few buckets as a mobile welder. You'd be suprized
I was wondering why the bucket drop. Now i understand. Thanks
A GOOD drag line operator wouldn't beat his chains and bucket up like this guy is doing.
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....
I'd say it's unfortunate for us to see how the bucket lands but it actually does cut the cycle time, means more productivity
I know nothing about this stuff, and I thought the same thing. Why is dropping it like that? Because it's sand? It's still abusing the equipment.
WHEN you bang your chain against the bucket it will wear them out faster . The crow foot is real heavy it will take a toll real fast.

An excavator in the pit to a radial stacker would be more productive. and a lot less expensive. This is Old School tech! You can have that!
If you look carefully, you'll see that he's feeding the processor as fast as the processor can move the material.
Me reading comments: "i had no idea there were so many qualified drag line opperators on you tube."

For this job i would use an other bucket, to hold more sand in the bucket and there for the under line in a higher position.
Keep on throwing the bucket till it you break it. If I had do that when I was an operator I would have been fired on the second throw.

wonder if it might be more efficient to mine this by suction...its loose enough....just a thought....
That is one beautiful machine. Is it sand they are mining?
Powerful winch to pull that bucket through the sand like that
I was thinking the same thing. Made me think, how much weight can that winch pull in? Imagine the strength of one of those old huge draglines.

wtf are they MINING? some info would be nice
me living in iowa watching this like 0.o
Id like to know which mine it is cause ive hauled out of just about every single one in iowa lol
is it me or does it look like you can put a bigger bucket on considering itsonly sand??? doesnt seem to be stuggling at all

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.
Why is this job better suited for a dragline vs. a large excavator?
Just curious...
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.
doesn't excavators have long arms now?
Long arm excavator has less than 1 cubicmeter bucket so it's not productive
Зачем 25 тонн противовеса?
Я вот тоже смотрю и не понимаю, зачем такой тяжёлый противовес
why bucket so small?
Chow👍👍👏
Skill.
Brand new machine 4 years ago, whats it look like today?
If it still had the same operator then I’d suggest it’s wrecked
what exactly is being mined?
KeenLaF gravel. For use on gravel roads in Iowa.
Anybody know why he drops the load in that hopper?
Check out my channel you'll find that we are feeding a rock crusher
how much is the price of this dragline?
1.3m USD in 2016
A lot of weight ... I don't think I'd have the nuts tossing that weight around that close to such a drop ...
Just sayin.
chain rattleing ,bucket slamming ! maybe someone should tell him ... smooth is how operators and work
As correntes não tem a mesma medida. Isso prejudica a produção e danifica todo equipamento.
I will never understand why they keep pulling the bucket in when the bucket is full why not just pick it up you're wasting time
COOL !!! where abouts in Iowa ?
jetegtmeier71 we're portable so we are all over in the northwest corner.
cool cool just wondering ,I'm in Waterloo :)
My grandfather used to have a couple of drag lines for his gravel pit operation near Charles City. I remember riding in one once when I was a kid…but cannot tell you anything about it. I do know you don’t want to park them on the edge when heavy rains are coming!
A good operator is poetry in motion!
Dry mining? Crap, it's strip mining
Good
Why is he so rammy?? Shit gets broken like that ...
I've seen them slam those into solid rock selfs just to break them apart. The sparks are amazing to see!
Iam dranline operator TWL 101ME INDIA
where is this at in iowa
Why use a crane instead of a excavator?
DieselTech73 this thing can reach much further down
Did you ever get the video done from the seat? Just wondering.

Interesting. Seems a big machine to move not much material, why use this method and not say, excavators/dump trucks, bulldozers etc?
Mike D less fuel
this is not as large as built on site like the Cat 8750 dragline, it is a duty cycle crane built for production capacity and thus can be partly disassembled and transported in two or three transports
ONE guy to hire.
Can’t imagine what a brain full of mush after running that for 8-10 hours🤪
Whats the reason you need to slam that bucket down like that. Holy shit man
It would seem it's because has using swing momentum to reach out further then the boom. And the bucket probably doesn't care.
Would a long reach trackhoe not be faster then this drag line setup?
You would need a really really big long reach to move the same amount of material as this. we are currently using a 6yd bucket moving material from 45ft deep with a somewhat larger radius than Long reach could reach. On a good day if our crusher don't break down we can move up to 10,000 tons a day. The size of a long reach you would need to compare to this dragline I would imagine would be way too big to move from site to site.... We are portable operation that usually moves seven times or more a year
Thanks for reply looked like soft enough material you could put large size bucket on a trackhoe and the speed of the machine might make it worth while but cool to see dragline in action
Cái xe to mà cái gàu bé tí
And overfilling that poor bucket. Half of it is bring spilled anyway..
Yea Alex ill take shit that randomly gets recommended to me for 500.
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
dump cable is too long
I thought those things were a thing of the past. Wonder why they wouldn’t use a front loader or an excavator
