Cat D19-750 dozer???

I had a load of pipe delivered today, and got to talking to the truck driver. He said he'd done heavy haul for a number of years (said he's retiring next month after 41 years of driving), and was telling me about some of the loads he had hauled. Anyway, he said he moved part of a huge Cat dozer from the plant in Illinois to a gold mine in Nevada. Claimed it was called a D19-750. Said the track frames were 51' long, tracks were at least 8' wide, blade had to be moved in 3 pieces, etc... He said it was supposed to be the first one they ever made, and was being taken to that mine for testing before production. He said he had moved D-11's before, and this thing made them look small. Said it was powered by 2 V-12's.

Does anyone know anything about this? I would have thought he was full of crap, but everything else he talked about having moved sounded realistic. And by that, I mean he seemed pretty knowledgable about other large equipment, and what it took to haul it.

It just seemed kinda far fetched to me, but I'm by no means any type of authority on large mining equipment. The biggest dozer I've ever been on, or will probably ever be on was a D9-L. It just made me curious.

I wouldn't put it past CAT to come up with a bigger mammoth machine to stay ahead Komatsu. I work in Peoria, IL and get to see all kinds of their machines loaded on rail cars and semis. Haven't seen this one though.

Those actually do exist. They are ment for filling in parts of the mine once that part is no longer needed.

They go as large as D57.

That's all for working mines. Want to move a mountain? the D19 can move it bit by bit.

Anything above the standard D11, is typically going to be custom made. Not standardized. Only two items for mining equipment that's standardized, are the massive "Dump "Trucks" and the massive Excavators. Everything else is custom as far as mining stuff goes.

the pic in the link you have there is a komatsu 575, not a cat...handtpipeline said the trucker told him it was a d-19-750 cat dozer

Apparently the truck driver isn't the only one who's been smoking someting funny......LOL.

lots of people call any tractor on tracks a cat just like they call anything on rubber tires with a bucket on it that loads trucks a payloader, or every scraper is a tournapul, or used to be.

I don't know, I would have just passed it off as BS, if he hadn't had seemed as no-nonsense and knowledgable about large equipment as he seemed to be. He absolutely claimed it was A Caterpillar, and I think he said from Peoria Illinois. I'm sure he said Illinois. I also forget how many trucks he claimed it took to move it. It wasn't the kind of story someone usually makes up as they go. He was too descriptive for it to be made up on the spot. He said I believe that the track frames were each 51' long.

Is that something that Cat would possibly do, build a prototype and send it to a mine like that for field testing before any production run? Or would something that large just be built on a custom, per order basis? I can't see there being a huge demand for such a machine, kinda like a 575 Komatsu. And how would they keep such a beast quiet in the industry?

That would be fantastically large, cause I think a 575 is only about 40' from blade to rippers



And, if y'all will sit on Tiny: Truckdrivers are renowned for being full of it.

IF, and it's a big if.........Cat were to build something like that, it would go to their proving grounds and have a bunch of the bugs worked out of it before it went to any mine to test out. The biggest dozer Cat has built is the D11T. There are claims that they have built prototype D12s, but from the sources I have, those are merely stories to try and make the story teller look good. I have no doubt that a larger dozer has had planning work done for it, but there simply isn't a big enough market for one at this point.......with the technology they are currently using.

Now, once the electric drive is worked out on the larger machines, this might change things.....dramatically.

Cat did twin 9s back before the days of the D10 so anything is possiable. There were a few side by side 9s in the strip mines of Ohio.

Most all the mining was/is in the east central and southeasten part of the state. Some of the largest mining shovels in the world worked in that area with the last one being retired and scraped just a few years ago. There was a large mine at Zanesville Oh operated by AEP for years.

Google up the Silver Spade or the Muskie and check out the pics...... I think your will be impressed.

Truckdriver... driving 41 yrs? Started about 1969ish? Sounds about right... "Lucy in the sky with Diamonds"...

Personally I am not buying it. Even for a non production model. I load truckdrivers and even used to be one.... If they think someone will believe anything they are being told? It's STORYTIME....

There are indeed surface coal mines in eastern Ohio (also underground coal mines). I worked from 1978 to 1987 as a Reclamation Specialist for the US Department of the Interior, Office of Surface Mining. But, please, don't hold that against me!!
