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

This video was taked in our customer's constrcution yard. This is a Komatsu D575 which was the biggest bulldozer in the world. This bulldozer is doing the ripping work with our company's ripper shank tools.

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.

[@jeff5798]

maby its better to use drilling machine and load the holes with 5 to 10 tons of nitronobel dynamit....

I was just waiting for that shank to break. Seemed like he was running at low rpm though. What a waste of such a nice machine.

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.

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.

[@livingbeing1113]

The Komatsu D475 is as big as a D11, so the Komatsu is still at the top of the pile with CAT, even without the D575 monster.

Well this Komatzu dozer is big, and it is still struggle to rip up this rocky patch, it might help if the operator adjusted the ripper tyne so it was angled a bit forward of vertical rather than being behind vertical. Having it a bit forward help lift the hard crust and rock while having it angled back is generally less efficient and tend to blunten the ripper boot (point) quicker, and as this powerfull dozer is notorious for wearing out ripper boots that might be worth considering $. Someone suggested blasting the hard ground, and it may be the dozer was preparing the area so drilling equipment could get onto it and drill a pattern of blast holes. But then it may also be that nearby infrastructure could get damaged by " fly rock" from a blast.? Oh, and drilling and blasting can also be both expensive and challenging, especially where the ground has a mix of loose material and hard rock as the lose material tend to fall back into the drill holes making it difficult also to get consistent fragmentation of the blasted area. Supervisors and engineers try to assess such factors and employ the most cost efficient methods available in the mining or quarrying operations they are responsible for. 🙄... Stay safe, ☆ Niels 👍...

The D475 is probably around 130 tonnes. The Acco had two CAT scrapers engines put togheter if i remember correctly, the D575 uses a single more efficient one, and the Acco was also difficult to operate.

Hello, mi nguyen. The Acco dozer to the best of my knowledge never struck a 'blow in anger' but that was due to circumstances, NOT to the inability of the machine. It and the Acco grader, which was even bigger, were built to work in Algeria just about the time of the Lockerbie plane bombing in December, 1988. After it was determined that Algerian terrorists had been responsible for the bombing and Algeria refused to extradite them, trade embargos were slapped on Algeria and Acco could never send these machines to their intended destinations. Your statement that it was just for show and wasn't a 'functioning' machine is just PURE BS. Just my 0.02. You have a wonderful DELUSION. Best wishes. Deas Plant.
