The biggest and the smallest, what a contrast.

Nice...Do you know what models and makers they are? Just curious.

I can't quite make it out but I'd bet Komatsu. My sons and I have several construction video tapes and one shows the worlds largest dozer at work in a mine. It was Komatsu and looks like the one in Dozer's picture. Fun stuff, eh /w3tcompact/icons/smile.gif

 

[Dozernut]

There both Komatsu. The big one is a D575A-2SR super dozer, 290,980lbs with a 70 yard blade, over 1000 hp. The small one is a D20, I believe an A model, around 10,000lbs, 45 hp, about a 2 yard blade.

DozerNut,

Well, can the old D575A-2SR, who comes up with these names /w3tcompact/icons/smile.gif,
anyway, can the Big D get my 36 inch oak stumps out of the ground? /w3tcompact/icons/wink.gif

And how many gallons per minute does it use? I'm concerned about its
fuel usage. Its the one thing keeping me from buying the old Big D....

If you have one of those you just gotta get a LeTourneau 2350

Just shy of 600,000lbs its bucket holds 53yds with 2,300hp choice of Cummins or Detroit Diesel power

I was sure those things ran on batteries.

 

[DarinRay]

Now that's some power. I am considering buying one of those pieces. Of course it was the D20P or D21PG and not that big one. /w3tcompact/icons/laugh.gif/w3tcompact/icons/eyes.gif

Yeah Paul, I guess the diesel powers the generator which charges the batteries which turn the electric motored wheels?

 

[looch]

Looks like it, Steve. I just visited their website and got the facts.

I saw a show on TLC (Monster Machines?) that made it sound like this thing ran on batteries - which is different than just the propulsion system being battery driven.

 

[hazmat]

They use the diesel/electric powerplant in trains too. The reason is it is easier to "throttle" the electric motor than to make a clutch big enough to start the thing. Also, an electric motor has 100% torque at 0 rpm, just what the doctor ordered to get the dozer moving.

And Bob LeTurno came up with that idea back in the 1940s, never went to college, and never drew blueprints for any machine he built. He believed blueprints were needed to make copys of machines, not the first one.
Drive gears on the early machines were cut with a pantographic torch system, and then run in a sandbox (large) to mesh the gears.
The original company was called LeTurno-Westinghouse because Westinghouse provided the generators and motors.

Years ago read a book about him and his company. Amazing story and amazing man. Went from rags to riches to rags to riches to ... well his business was either feast or famine for many years. The most memorable item I recall from the book was his philanthropy. During the later "good times" he and his wife lived on 10% of their personal income, lived simply and invested/gave the rest away. (But he still had his tractor toys /w3tcompact/icons/wink.gif/w3tcompact/icons/smile.gif)
