The biggest bulldozer in the world Komatsu D575 working in the mountains

What a beast. I worked BIG most of my life so I am a pretty happy camper right now eh ! both operating and mechanical services. Loved every moment of it.

He definitely needs to work on reangling the ripper shank once it's in the ground. That's why he's not able to rip better and more effectively. Once it gets into the ground, you have to angle the upper ripper hydraulics out so the tooth on the shank gets a better angle and can apply more of the force on the tip of the shank rather than on the entire body of it. The way he's doing it is damaging the entire ripper shank and it'll eventually break it off.

Eu amo demais os Bulldozer Komatsu. O D575A é o meu favorito! 🥰❤️❤️

The forces on the drive train must be enormous.

This is D575A-3 SR on video if i am not mistaken, with weighing 131,350 kilograms (289,580 lb) also exist SD version, most heaviest of them 152,600 kilograms (336,400 lb)(more heavy frame and structure) but SD version without ripper only giant 69m3 blade and also have giant 96 m3 blade as option

Nothing but rock. The claw/hook is tearing it up. Bulldozer just humming along. 😃

Los que verdaderamente amamos los tractores gozamos al escuchar el motor,las orugas,el sonido del acero contra la dura roca.Y no alguna tonta música que ponen en los reels.

Magnificent beast! Sumo wrestler on treads!

Komatsu made a big splash when this was introduced several years ago. Then it just died, this is the first I have seen of it since. CAT even had a helicopter fly around and take pictures of it. CAT still owns the large dozer market with their D10 and D11. Rumor is they have a D12 designed on computer but have not built any or disclosed any to the public.

If I remember correctly, Arch use to have one at their Wylo mine in southern WV division. Not much of a market in the states for one, with all of the big strip jobs being shut down. Maybe China where they’re building 300 more coal plants as we shutter ours.

Komatsu? Number 1! 🚜

the sound of the rock breaking awesome,snap crackle pop.

Can’t beat Komatsu dozers for ripping there pure beasts he’s got about 5 feet of shank in the ground these dozers are unbelievable

Kaipara operated 2 of these at Stockton open cut NZ while I was working there 2006 - 2007

Needs a dedicated pipe line to feed it . I’d hate to get that fuel bill.

Look,to all of you that bash Cat. Cat could build anything they want. Just watch a D11 working along side a 475 or 575. There is no comparison. Cat is #1 in heavy equipment for a reason. To build the biggest doesn't mean the best. I think the 575 is like 80,000 pounds heavier than a D11. And just the fact they quit making them says a lot. I've been an operator for 40 years and have run both Komatsu and Cat they both make good machines. But in my opinion the mining machines I'd give the nod to Cat. Believe me I'm not a "It's gotta be Cat and only Cat" type guy. But run a Cat on a 12-14 hr shift,then do it in a Komatsu the next day. On the 3rd day you choose which one you want to run.I bet I know what most would choose.

'SD' or Super Dozer. Both models can move 90 cubic yards (69 m3) of material per pass using the standard blade. The D575A-3 SD Super Dozer can move 125 cubic yards (96 m3) of material per pass if equipped with an optional blade. The D575A-3 can dig to a maximum depth of 6 feet 9 inches (2.06 m) using its single-shank ripper.

Nz has two of them ,both with ripper shanks and one is remote control unherd of in 575 world

Me fascina ver ese bulldozer trabajando Saludos de México

I couldn't see the scarifier, at first. From the noise, and the lurching, I thought its sprocket might be slipping and jumping the track pins, on the other side. Boy, was I wrong!? That is a tough pull.
