I would also opine that the ratio of D575 to D475 was more like 50+ to one. Does anyone here know the total production or current population of D575s? I'll ask PG, but he may not answer. As previously mentioned, they certainly weren't flawless by any stretch of the imagination from what I've heard. In West Virginia, I was told stories of major repairs taking sometimes weeks to resolve because of parts having to be fabricated in Japan and then shipped. Dont' take this out of context as I was also informed that when they were working, there was nothing else remotely close when it came to material being moved in a shift. Please use this before clicking "post"? You may be surprised with what you see! After 20+ years the technology is dated, but I wouldn't be surprised to see a new iteration of something beyond the D475 in 3-7 years and probably diesel-electric "hybrid" at that point. Something that needs to be considered in the potential D12 vs D575 context is if Cat was to introduce a D12 would it be D575 size? Personally i think not and i think a D12 would be more in the 125 ton range and around 1000HP. With ultra class shovels and trucks now becoming the norm and tip heads not changing i see safety rules coming in where trucks will have to tip short of the edge and more dozer pushing being required, if you have ever seen the pile a 400 ton truck leaves in a block tipping or paddock dumping operation and the job a D11 has to knock it down you will know what i mean. The other side of it too is as more autonomous trucks come on line i see them mandating short tipping on dumps with everything having to be pushed over the edge. I think it would be fair to say if Cat built a D12 it would sell very well and much better than the 575 has and for all the same reasons today the more expensive D11 outsells the D475 by 3 to 1, back up and support, simple as that. I was told by a Komatsu salesman three years ago or so that the D-575A had been discontinued. Is there many other places Besides West Virginia and Kentucky where these machines have been used? I know I talked to someone a few years back that said that there just wasn't much of a market for these big dozers - the places that could use them was basically places where dozing was the main way of moving material - thus places in WV and KY. Would a D12 even be worth having/operating? What would such a monster cost? $3 million? $4 million? I'm just asking. Anybody care to see a life sized version of the giant dozers from the movie Avatar? The Komatsu D-1675 I'm just an observer from outside (of the mining industry, etc.) I have learned things from reading and talking to the occasional person I cross paths with. Gav, the specs for the 575 list an operating weight of 126 tons, so that would place the dozer you suggest squarely into the same size class as a 575.but with 150 fewer ponies under the hood. With the D11 running right around 115 tons right now, I don't think a 10 ton jump would be that great of an idea if you only propose jumping the HP by 150. That would make it the same weight as a 575, but leave it 150 ponies shy. Spreading a 400 ton load 1 meter thick only takes 5 relatively easy passes.Īlso, a D11 doesn't really have much of an issue pushing 400 ton loads. So until they upsize the trucks from 400 tons, I don't see a real need for this size of dozer. I'm sure they would sell better than the 575 did, but I'm not sure they would be a great seller in the grand scheme of things.yet. Give it time, and I'm sure a market will develop, but we're not there yet.įrom the info i have Brian the D11T CD is around 115 ton (incl SS ripper) and the D11T with U blade and SS ripper is 104, some wear plating no doubt adds to that but i am talking factory weights as they are easier to keep track of.
