the force on that ripper boggles the mind

Finally! An OPERATOR that understands what a dozer ripper is for and how to use it! There is a reason there are hydraulic cylinders on the ripper that change the angle of the ripper shank! All the way vertical to penetrate, then roll the shank forward. This does two things. One is that it makes the shank more efficient by using the weight of the material to help traction. Sort of like an axe into wood. Vertical it chops in, less vertical it will lift long sections of wood. But the biggest reason an OPERATOR does this is to keep the ripper tooth sharp! Leaving it vertical quickly rounds it off. Rolling forward always leaves and edge on it to bite into material. This Operator was able to start with the ripper rolled a bit forward due to the open face of the rock, didn't need to penetrate to get started. Every type of material will have a slightly different angle that works best. From coal to softer slate to weathered rock. Good job using the decelerator pedal to maintain traction without excessive track slippage. It is also easier on the operator! This is a LONG day ripping hard rock. Yes this dozer has an exhaust leak. Not a critical issue.

Thanks Max for sharing.......love watching those big tractors hard at work mate!

@jeryl68 thanks for the kind words buddy. the smoke is sillicone dust & caused by friction & is not good for the lungs. & yep it is a hard days work & the bosses & owners have no idea what so ever how tough it is on the operators.

Those big ol' cat motors are like a symphony. Great video.

I could listen to that engine all day!

I woke up this morning and I heard a cry I saw it was granite about to die For on its head sat a d11 Ripper out and tearing for heaven Granite called for strength of will But D11 was having the thrill Planetary humming and tracks a squeal As a D11 plows this freaking hill !!

I love ripping. It's therapeutic. Just brute power.

Hi, I am into all things earth moving and your video shows a detail of ripping I have not seen before, thanks. mrbluenun

That operator is babying that beast

These things are truly, Modern Marvels! The size and power of these things, just boggle the mind..... I wonder if CAT has any plans, of going even bigger!?

No silly music, no pointless face flapping; just raw power. I'm glad I'm not the brave soul in the cab having my innards jarred and my hearing assaulted during the working shift.

Mate what ever that company is paying Eddie ,they should double it. He is saving them twice that in track gear alone. He is one of the best rippers of the hard shit I have seen. P.S Is that at East Kurrajong Frontrow?..Great vid Bud

thats some big balls man. i love that sound

@c931D9 thanks for the kind words. it takes a skilled operator to do this kind of work & make the boss a dollar but boy isnt their some cowboy operators [drivers] out there .

very nice machine.the whole time i was pushing it around in my head, like i was 6 or somthing lol. great vid

great video! the best sound i've heard from D11

nothing beats the sound of a 3508 under load!!!

Incredible machine!

Dam rite! this is what keeps the world turnin!! dam fine vid!! CAT POWER FOREVER!

That's some power ! Get butterflies in my stomach every time he backs up to the edge.

Outstanding close up ripping action

That dozer sounds like a freaking snapper lawn mower!

Its a pain in the ass where the rock packs up under the ripper frame, that's where a Kelly ripper scores

Amazing sound CATERPILLAR

Sounds like a 3508 to me....go cat diesel power!!!

awesome machine....

Hi 13frontrow, And thank you for the upload. I love to watch these beasts working so hard. Sounds a bit dodgy though.

@13frontrow Now that's some hard ripping. Good video...close to the action.

Wawww se jeant thanke you very match forever goode job 💪💪💪💪💪💪💪👍👍👍

i think it sounds kinds cool raw power love it

I could stand there all day and listen to this d 11

exhaust leak ?

no mate the 11s are no worse on air filters then any other dozer.all dozers creat dust especially wen its dry. the tractors also have an indicator that alerts the operator when the filters are blocking. some times in extreem dusty conditions the filters may have to be blown out with compressed air after each shift. only takes 10mins to change a set of filters. the more hours per day these babys work means more money in the bosses pocket overall not just to pay its own way. thanks for asking.

Esse bicho é um monstro, magnífico!!

hermoso sonido!!

Keep up the good work.

ur right it does sound like a miss in the engine but she,s an oldie & good 1 & is still going strong to this day . just a rough guess id say its got a blown exhaust manifold or gasket & some work on the injector pump & injectors wouldnt go astray. thanks for posting buddy.

Hey! Wonna get High? Save that smoked created by the friction...lol

Frontrow, I hope the bosses there at TRN understand what a top notch OPERATOR they have employed at your quarry Bud. The money he is saving them in running costs is huge. My old man would have hired him in a heartbeat and he had very high standards and didn't see the funny side of dickheads on his machines. Your videos are awesome mate

just seen yet. super vid

wow nice vid!

nice!

good vid!

It sounds like a frickin Locomotive!

There you go would be ripping operators, exactly how it should be done, throttle control and skill especially working on that edge, super nice touch getting the parked up Komatsu in the frame frontrow!!! Sounds like some exhaust work coming up soon too

great video

Great Vid. Man that's got to be hard on gear

thanks for the comments buddy & you are correct on all subjects.

The perfect machine, The perfect Operatör

Nice 👍

That should be me Up in the cab Of this big chunk of American muscle dozer

he is ripping sandstone which can be extremely hard. is mainly crushed to 75mil & sold as a road base.

Brute force - nice/ wow..

thanks for the kind words gavin. exhaust sounds mean ay.

my "dolby audio" is the MAX POWER from the videos.. the Windows... oscillating WOW

Dude that's bad ass man 😎🍕✌

to the questions above ...1st he is an experienced operator and he is using his deexcellator pedal to not spin his tracks when ripping ( so he is up and down on his pedal ) 2nd- the edge is not dangerous -he has a natural slope into the pit -if the edge was a vertical slope from a high wall ( blasting ) - he would be far more cautious 3rd-that is not dusty - try pushing on a coal pile in a 30mph wind coming at U-lol clean filters as per conditions ( operators are responsible to know when )

I heard that D11's are the worst on air filters. Does anyone know how many times they have to change out the air filters? Is ripping worse then just pushing a pile as far as kicking up dust? I understand these machines are so expensive that they have to work 24/7 to pay for themselves. Is this true? If the air filters clog unexpectedly especially on a night shift, how long is the machine down? Appreciate any comments. Thanks

Is that a broken manifold or a dead cylinder in that engine ? Other than that,.it is a good video on how the ripper earns it's keep !

@13frontrow i guess they set up for one or the other.? like the gearing in the planetaries etc......

is that one of those impact rippers that was discontinued because it would crack the dozers frame?

@mrbluenun thanks for the kind words & subbing buddy.

@Mattessj you could have a point there komatsu definately has a lower 1st gear.

The unstoppable object meets the (almost) immovable objects. Probably a hundred tons of force at the tip of that ripper?

@generationll thanks buddy.

Excelente manobrador

Is that a hammer impact ripper or just a regular ripper. Seems to be doing the job either way. Thanks to the great vid.

@brocparsons thanks again buddy. got more coming.

Its the dust off the rocks its ripping / breaking. And wow this thing is a total heap lol, how many hours are on it? I will swap you material anyday, that's beatiful material to work with compared to our floors. damn blast crew lol

@calaverex thanks mate.

the smoke is silicon dust which is not good for the lungs. is caused by friction.

@florin171 thanks for subbing mate.the komatsu 375 in the background is mine & is no match to the D11.answer to your question is a tough 1.komatsu 375 v D10N&R & 475 v D11 I would give the nod to the komatsu for ripping but CATS are faster pushing dirt & scrapers.

I need this kind of ripping bildozer to dig mountain to make my land cultivated

Maybe the audio in this video is affected by wind or just poor quality sound,but the engine sounds like it has an exhaust valve issue or an injector problem?

el tractor suena como una cafetera y el operario esta ripando con las botellas de doble efesto sacadas

stand in front of it & see if you can stop it then.

Compact Design = Bulldozer

Smack a hammer on some blue metal when u get the chance and see what happens! it will take a lot of force to break it.and when it does watch the splinters and dust particulates you create.Hard rock equals friction add to that the weight on the shank of that ripper trying to force its way thru it and that would equate to stupendous forces.hence the reasons you see the rock atomise.The experienced blokes know how to work this stuff, pitching the ripper depending on the structure.if he knows the general lay of the ground he will have a good idea how to work it.This guy knows his shit. he just needs to be appreciated and put in a nice new machine.but i know he knows he can do as gooda job in this and probably as effeciantly in this old girl.money saved.

Poder CAT o mejor dicho q wevotes tiene 💪

Manifold gasket is blown.

yeah...he's doin it right. And theres nothing wrong with the way it sounds. It's a whole lot different in real life than from a avi recording.

What is the steam/smoke coming from every time she starts ripping?

just having a rough guess in this type of rock it would probably generate about 400 ton per hour .

Yeah Go The d11

Think it's safe to say she needs a good service

@JimHowDigsDirt thanks buddy.

💪💪💪💪💪💪💪💪💪

@buckshottfonk thanks buddy.

That PLACE ! NEEDS ! CEE !! FOUR !! THERE !! THE ! DOZER ! SOUNDS !! SICK !!

Cê tá louco meu e muita brutalidade um bicho desse. Respeite cartepillar

@brocparsons excellent nick name u got there to buddy.

One of those jobs no short cuts rip it properly extracting is much easier need lot of good gentle operator patience with machine

Vedi la caterpillar come spacca mi sembra un torrone. Solo a lei l'onore e la gloria di esistere. E' inutile fare paragoni e' l'unica al mondo che spacca la roccia o altro senza mai fermarsi.

@bigfranco87 got to agree with you there. thanks mate.

tremendo fallo de seguridad hay maquinaria aparcada debajo del talud y otra maquina aparcada en la zona la zona de influencia del d11.

I hope he's zoomed in. That's way to close.

So at what point do you stop to clear off all that crap? It seems like after you have cleared four pulls wide you would want to push the crap off so you stop running over it and punishing the u/c. No?

Manifold gasket's leaking, makes it sound bad!

Sounds like an exhaust leak to me
