DOZER

[Kevin_in_Mi]

These two beauties were on display at the Mid-Michigan Antique Tractor Show in Oakley a couple of weeks ago.

/w3tcompact/icons/shocked.gif/w3tcompact/icons/smile.gif/w3tcompact/icons/cool.gif..now there a pair of twins I wouldn't mine having around the home. /w3tcompact/icons/wink.gif

 

[ScottAR]

How 'bout these?
This was the biggest dozer Cat made till the D11 carrydozer came out.
Two D9s connected with the blade in front and a crossmember in the back. The SxS D9H had 820hp pushing a 24 foot wide blade. Steering stopped one outside track while the other 3 kept going. Production ceased in '77 after the D10 was announced.

 

[ScottAR]

They made twins long ways too. DD9s were built to push scrapers on big jobs. DD9Hs had again 820hp. Were produced until 1980. Steering was interesting. To turn right for example, the front tractor's right track would stop and the rear tractor's left track would stop so it could articulate.

 

[ScottAR]

In case it wasn't obvious, Yes, I REALLY like dozers. /w3tcompact/icons/love.gif

 

[DarinRay]

Wow, just imagine the damage one could do with something like those beasts. /w3tcompact/icons/smile.gif Yeah I kinda gathered that you might take interest in the dozers. /w3tcompact/icons/laugh.gif Never can get enough pics though of any type of equipment.

Tell me about it... I have about 40 meg on file... growing everyday.

 

[Thomas]

Remeber watching on PBS couple years ago in which two dozer work together like that out west in a mining area..leveling the landscape..indeed it was very interesting watch the two operator working together.

Scott:
Many a year ago[ 1960's] the company I worked for had two D9's hooked in tandem [ one operator ] that were used for pushing buggies.

Here's a picture for your collection. Caterpillar makes the DEUCE for the Army. It goes 33 mph on rubber tracks, and is C130 transportable at 35,000 lbs. It pushes about equal to a D4/D5

Yeah, I guess those dozers are impressive enough for small equipment/w3tcompact/icons/wink.gif--but follow this link to pictures of the bucket from the <A target="_blank" HREF=http://www.little-mountain.com/bigmuskie/bucket.html>Big Muskie</A> dragline being moved. The Muskie's stats:

Weight: 27 million lbs., or 13,500 tons
Bucket Capacity: 220 cubic yards, 325 tons (12 car garage)
Height: 222 ft., 6 in.
Length of the boom: 310 feet
Length of machine with boom down: 487 ft., 6 in.
Empty bucket weight: 230 tons
Width: 151 ft., 6 in., compare to an 8 lane highway!
Cable diameter: 5 in
Electrically powered: 13,800 volts
Mobility: hydraulically driven walking feet

My father worked in the coal fields and when I was a boy would take me to see the
<A target="_blank" HREF=http://www.geocities.com/Heartland/Ranch/1201/mountaineer.html>Mountaineer</A> at work. It was next-to-nothing, at a mere 5.5 million pounds, but it seemed fairly big at the time. When the Muskie came on line in 1969, we made a trip down to see her--unbelievable!!/w3tcompact/icons/shocked.gif/w3tcompact/icons/shocked.gif

These machines destroyed a lot of mountains and it all probably could have been done different, but they were sure impressive sights.

 

[ScottAR]

Egon, did it look like the one I posted on page 1? Did you get to operate it? What was it like?

BrentB, Many thanks! I'd been looking for some web pics of the DEUCE. I have some in a book but not for here.

BTW, anyone with an interest in Cat machines owes it to themselves to get "Caterpilar Chronicles" by Eric C. Orlemann. Great book. I have no connection to the author but its the best source I've found that actually has decent pics of everything new and old.

Scott:
It was two regular D9's hooked back to front with a big ball type hitch. The operator sat on the front one. One set of controls for both units that were air operated. The front dozer had a push block rather than a blade.
I didn't operate any equipement other than a P/U and had that stuck most of the time.

Somthing like this? DD9 pushing a 666 scraper. Hmm thats about 1700hp on the screen. (sigh) /w3tcompact/icons/love.gif

 

[karmakanic]

It's not a D-11, but here's a pic of my pride & joy pushing some logs into the burn pile. It's a John Deere 550 with winch & 6 way blade. It was built in 1980, but only has 1550 hours. Came from the Oklahoma highway department and was used as a pipe layer, thus the low hours.

Nice looking dozer for its year. /w3tcompact/icons/shocked.gif

 

[DarinRay]

Yes,, very nice looking dozer. Want to sell it?

Darin

 

[Egon]

That's it but they were pushing 641's

That loading sequence indicates the buggy is being overfilled. Pit boss not happy.

Egon

 

[ScottAR]

Pit boss not happy, I agree.
I have another pic of two quadtracks push loading one scraper (a 651 I think) but its 1kb too big. /w3tcompact/icons/hmm.gif

 

[ScottAR]

Just for kicks, here's a Euclid/Terrex TC12/8280 (brand/model depening on year) Twin engines, the sections pivot on a central "axle". Different anyway.
