Woow such a gentle touch on this old 1980 drag line no loud bang no bucket drop just nice and easy almost like the machine is dancing no loud bang no slamming the bucket down No wonder its like new almost fora 1980
You know, if you had a dragline that would....Wait...Never mind...:)... 1980 Huh?...That sweet old girl has earned her keep many times over...Nice to see older equipment being still used...From Philly with love and success to you in the new year!
New subscriber here and a thumbs up on this video.What I see is a machine that is maintained and not run till it falls apart:good job.Support pad looks to be 6' thick so machine is operating on a stable base to limit structural stress:great job.Hearing squeaking sheaves: might want to look into that. Couple of questions: what is the fuel usage rate per hour? Is it a single shift machine or are you running it 24/7? What is the maintenance cycle schedule?(one or two shifts for maintenance every 7th day?). Looked for the coal seam on the cut face to left and didn't see much:how thick is the coal seam there? Type of coal? More than a "couple" of questions but inquiring minds want to know.
I get the impression that big draglines are being gradually phased out as they get old and die. They don't look all that efficient, but they do have a fairly large scoop and a pretty long reach. If they are being phased out, what is replacing them?
I really enjoy your channel, I think you do a wonderful job. May I make one suggestion. When talking about the older equipment. Could you give more information on that particular piece of equipment that you are filming? You tend to talk about various models. I would like to hear more about the actual machine you are filming. Just a suggestion. Is it still in operation? Or how long has it been out of service. Things like that. Because I noticed people in the comments always ask you about that particular piece of equipment.
Why is he hoisting that bucket so high up. The pile he dumps it on is low so that's a big waste of fuel and cycle time. No wonder why the people in the comments say it's inefficiënt.
Is there also coal under where he is dropping the overburden, or is the seam narrow enough that he is setting down beside it? Awesome video as well. Be interesting to see what your filming equipment is
@John Cunningham thank you for responding and letting me know I looked it up on Google images now that I can see what it is it makes sense how it works
Justin i know where the cat 6015b is it is in Oneal quarry in montevallo Alabama you have to go check it out soon i AM begging you for a documentary and a video of it in action PLEASE IM BEGGING YOU MY SON LOVES YOUR VIDEOS SO PLEASE DO IT
Tricia Asbra I do construction work for a small company and we done a job in Montevallo Alabama replaces some curb and stuff, where’s that quarry at? Biggest excavator I’ve ever seen is a pc 8000 front shovel in a strip pit in curry Alabama
It actually is. The machines moving close to 800 cubic yards an hour and spoiling in the old cut where the coal has already been exhausted. One machine, one operator. Yes shovel and truck is faster, but more than double the cost
Unless you have something better I can't see the money spent on this machine! There has to be something better than this very slow machine and the amount it brings out of the ground.!!!
PAmining As others have said, it is efficient from a cost perspective. On this job, the drags moving around 800 cubic yards an hour and spoiling in the old cut where the coal has already been exhausted. One machine, one operator. Yes shovel and truck would be faster, but more than double the cost with the additional equipment and operators. Remember, a worker is the most expensive asset to a company. To give you an example, the mine I work at operates ten 100 ton trucks and two 20 yard excavators moving on average 20,000 cubic yards per day when running 50 hours a week. The cost to run that pit is almost $1 million a month! If you were to run that same pit with electric draglines, the cost would probably be about half that.
