You can always tell a seasoned operator by how they back up, youngster’s hammer it in reverse with no thought of the wear and tear that’s put on those bad boys! Dollars and cents baby! Great video, thanks! 🙏💪🤘🙌👊
Right on! Thank you!
the operator in the middle is the best!! In my opinion. Very good video of 3 great machines
It's nice to see equipment like these D11s being looked after and earning a crust.
It is hard to appreciate the full power of these dozers sitting in front of a computer, anybody see the size of that rock the dozer was pushing around the 0:06 second mark, size of a small car!!! Nice videos as always!!
I used to run a late 80s d11 at a quarry. We used it to push a surge pile into a secondary crusher feeder during night shift. Talk about a ride when it gets a little sideways and the dozer is sliding sideways down a 200 ft tall pile of granite in the middle of the night. Def kept you on your toes! Awesome machines
I worked in a granite mine in the plant cleaning (shoveling crusher run) out the conveyor belt tail pulleys when the material would over flow the feeders... the good ole days. Sounds a little crazy, but I kinda miss working in the rock quarry :)
Just a exellent video of these mighty Machines thanks for posting.
Awesome video I love watching the d11 work🌟🌟⭐👍
Awesome Video. Just the Raw power of Cat engines
That's because this is PAmining!
Greetings from Pennsylvania! The Carrydozer features a more beefy heavy duty single shank ripper than the standard 11. Thanks
Haha, thanks! Glad you enjoyed it
We purchased one of these ,and it didn't take long for us to convert it back to a regular SU blade. They just are not heavy ,or powerful enough to continuesly do carry blade work. We found it to be a very inefficient set up.
I also can't see the face up or surrounds that these dozers are working on ,that's an awfully long push ,when they could load their blades up in 1!3 ,that distance
I could twke a 993k and one 777 or 785 rock truck and beat these two CDs anytime anywhere that the push length and size is equally as favorable to me as it is those CDs .
G Hall I don't doubt that. The granite tends to chew tires up pretty quick tho. I know the quarry I worked at tire machines were confined to haul roads. Maybe the dozer is slower but it might cost less to move that material with em.
Awesome amount of power on show. And expense!
Thanks!
Great Video of CAT D11R's dozing/ripping earth material.
You should see the multi and quad shanks! They're bad ass man
Ah, great video. Thanks! :)
Great video.

Greetings from germany, and gratulation for another great video :-)
one question: why did the D11`s have different rippers?
We have D11Ts and in all the research we could come up with the D11 was more reliable and cheeper to maintain than the 575
CAT.....POWER IS THE NAME OF THE GAME......GO CATERPILLAR.......
Nope because what they are working on doing is stripping. Where they start to where they begin to go uphill is cut. The coal is directly below them. The area where you see them pushing upgrade is where they are piling the overburden. The coal in that cut was already stripped out.
Pure Raw Power
Catskinner operator look great..abundance of common sense..
DAMN!!!
I want one of those toys..
now thats torque
just perfect view of d11 dozers 5*****
I like how they have the backup sensors...I'm sorry, but if you don't see a D11 backing up and you get in the way, shame on you, haha!
Great video!
Yep except this time there's no trees, just rock lol
The Komatsu 575 is a way more powerful beast and carries a larger blade, but they're not as versitle as a D11. Thanks
Whats the difference in the rippers in the carrydozers over standard?
Carrydozer has a more beefy heavy duty ripper
holy crap ,now that some horsepower !!!
this is badass
Amazing traction!
Just had a thought. Does the cooling fan draw air into the engine compartment from the front..or does it draw air through the side covers and then push it forward over the radiator? (to keep more dirt out)
Charles Harris The cooler/radiator are one unit on the D11 tractor. The fan pulls air from the sides and blows outward toward the blade. So, essentially, it is not actually sucking in air from the front
The fan blades on a cat "use" to be reverseable,you could turn the blades(lockable) to pull air threw the radiator or blow air threw the radiator.There was a vinyl bag that mounted on the front of the radiator in winter an had a tube running back to the operator on older open cabs for heat.
I wonder why Cat hasn't put a carrier roller on these bigger dozers. Guess at a mine you don't have to worry about track bounce causing poor finish grade.
I'll bet that the transmissions get hot doing these long pushes.
Great vid!
D11👍
avatar all over again!!!!! lol, very cool vid man!
Those D11's are beasts with mega power, How do you think the komatsu 575 would stack up next to them? and once again Great video.
Do the Cat cd dozers struggle to push the extra volume with the bigger blade, engine power is the same as the standard D 11.
850 horsepower they can carry up to 98yd
I need one of these to level out my 10acre block to build my house on and to doz 900 useless Caribbean Pine trees out of the way..!!
what is the advantage of hi drive tracks over normal Caterpillar tracks
less shock loading on your bull gear drive train because it is up off the rock surface
man id give anything to just push a blade full or 2 in one of them biggest i ever run was a D8T great video man. by the way where at in pa is this taken I'm from shippensburg south centeral
nice
pushing under full Throttle!
Nice and shiney they just washed
Justin please do a documentary on the komatsu D575
I would like to, however there's very few 575's in North America
This is the stuff that wears out even a D-11 in time. Some pretty hard
d pushing here, doing a great job too.
***** This is what a D11 is designed and built for. These 11's undergo a full engine and powertrain rebuild around every 10,000 hrs. Expensive to maintain, but a good maintenance program helps eliminate downtime and keeps them moving dirt
D-11's are built for work like this true enough. But blood and guts work in rock will wear one of them out just a bit faster than if it were pushing nice soft dirt or wood chips. The wear and tear here is enormous, and this outfit buys tracks and other parts differently than many operations where the ground is just a bit more friendly. Heck of a machine for sure, I'd sure want a considerate and smooth operator on mine.
What else are they gonna use?
I'd be curious to see how three Komatsu d575s would do on this specific job.
Komatsu wanted to place some 575s on our mine but refused to do a side by side comparison....
These cats do 1 an half to two pushes per one of the komatsu which makes the d11 much more efficient.
Eg. The cat pushes almost twice the product over a days work with far less running costs.
The komatsu is to big
@@vevohoeyo I have run a 575 Kajunksu, it will out push two carry dozer hands down, and I bleed Caterpillar yellow, where the Cats get the 575, when the 575 is down the Cats are still pushing, 575 is hard on turbos, and undercarriage is weak, where you saw that one carrydozer struggling, the Kajunksu would keep going with a full blade and even rolling material, and I was working in shot sandstone!!!
One of the D11's is not a CD, correct?
Yes. Two are Carrydozrers and one is a standard D11
I want one 😬🤖😬
Yeah, but getting squashed like a bug is a high price to pay for a moment's inattention. OSHA doesn't like it much either.
sucks to be the dude against the highwall
I would like to see d11's clearing a forest
TheFarmin' Giant73 it’s cost prohibitive transporting this machine down the highway to and from the job site. These are primarily quarry and mining machines. They never see a lowbed trailer.
It pisses me off that Nancy hasn't shut the electrical power to the White House off !
