is there such a thing?

CR500 hits the nail on the head. And as for doubting D11 would be used for pushing dumps and new operators are required when loads are not tipped over the edge i think you guys need to open your eyes a bit.

With Cats marketing prowess a D12 would sell, no question, is a machine of this size required, i think it might be a bit closer to yes than no now but i doubt Cat will do it, i have heard some powertrain work has been done for one but thats about it and if they had built one i dont think it would have ventured out of Tucson.

Hi, CarterKraft.
Yes, Buster Peterson did the conversion jobs on the D8's, which were 2U series machines, but Holt made the funnel dozer and root plow and, I think, fitted them.

Hi, Folks.
I'm with Gavin 84W on this one about loads not dumped over the edge. In some situations, especially when building rock fills, the last thing you want is to have the load, especially the whole load dumped over the edge. When the load is dumped on top and PUSHED over, some of the 'fines' are sifted out and remain on top of the fill, giving you a smooth surface for dump trucks, etc., to drive on and giving some softer material for a smoother ride for the poor, over-worked, under-paid, ill-treated and unappreciated dozer operator.


NO 'LOL' on this one.

or anybody with some info.
Back in the 70tys or 80tys Con Expo was in Texas. At that time a rumor was flying around New England that one of the pit owners had bought a machine from Cat.Suppose to have had a 25Ft blade,closed circuit TV to see blade, and I thought they refered to it as a D-10 - The rest of the story pretty much fit that "D-16" He supposedly bought one, at the show - but it never showed up - they claimed it had to many problems and Cat stopped production. Was this thing ever seriously considered for production? This guy was known for his Tall tales,(which I have always it was) But on the orther hand if he thought it would work and be profitable- he would have tried one.

Hi, OneWelder.
It is entirely possible that somebody purchased a Cat with a blade around 24-25 feet wide in the 1980's but I doubt it was an experimental 'D16' or any other machine larger than a D11.

There were several blades made for the original D10's and the D11's that were around that sort of width, mainly for coal stockpile work. I ran a D11N fitted with a 24 foot wide, 9 foot high coal blade. It sure did block out a fair bit of scenery in front of the tractor. It also moved a bit of coal in each pass.

Other than that, I know nothing 'cos Cat, for reasons best known only to itself, (LOL) does not consult with me on its various research projects.

Any idea who that was that supposedly bought it?

sorry to drag up an old thread, but i heard a rumer that there is a "D12 prototype" of some sort heading over to WA soon, anyone know of CAT developing one yet?

[Seabass]

I think Cat would have made D12, D13's to compete with the 575's but its really a small market (for now). I think if Cat thought they could make a buck they would do it. That said, machinery has been growing in size, not shrinking, so who knows what the future holds. Personally it think it would be neat to see one, even better to run one.

[rare ss]

there may be an uncreasing need for a large sized dozer as some sites down here are starting to run autonomas haul trucks with require the use of backhoe spec diggers hence sitting on a blasted bench which needs abit of prep to work

thought someone may know of something in the pipline

It won't be long and all the D8 size and up will be electric like the D7. Just a matter of time.
That D7 seems to be working out pretty well now from what I understand. Look for the D8 next!

I believe the D10 is the next intended machine to convert.

Even though I have heard the D7E is working well, I hear they're having issues selling them That's based on the purchase price being as high as it is, and the fact that contractors aren't seemingly able to charge as much as a D8, for a D7.........even though it will do almost as much work as a D8. So they seem to find it a better option to buy a D8 and be able to charge for it.

Don't know where this came from, but the next E was going to be a D6 but it's been shelved for commercial reasons. There are no 8, 9, or 10 E's in the pipeline, and no D 12 of any complexion. The 10 was never in the frame for electric drive.

I think one way or another you are Mistaken...... Future Dozers in a particular size may or may not be electric drive but there is a future model in the pipeline!!!!

[Greg]

D13? Oh my God. D12, yes, D14, yes. D13 gotta be bad luck. Anybody know of any company building anything and labeling it 13 anything?

That came from the pictures I have seen of the D10 electric drive test machine at Tinaja Hills. I was told once they proved the concept, the machine would be the next to be released.
