KOMATSU D155AX- 6 Vs. Cat D8R

- Опубликовано: 17 июн 2009
- More horsepower, more weight, and superior engineering equals more production. The Komatsu's superior ripper design keeps the track sucked to the ground for better traction. In this test the Komatsu had all three rippers in the ground compared to Cat's one. Needless to say the customer sent the Cat back.
I've done a simular test to this, but with an 8T not R. One thing no one has mentioned is that the Komatsu gearing is slightly higher than the cat. Plus its slightly more powerful so of course its faster than the cat.
While we had them on demo, we put them slot cutting for a day side by side. We checked the material with gps and the komatsu had moved more, and used less fuel.
Personally I like the Cat, but my company bought the Komatsu, and I understand why they chose it. Dealer is good too.
high tracks were never designed with the theory that they improve traction. the elevated drives were designed to keep the final drives off the ground to decrease wear on them.
That Komatsu is a beast! Nice video, glad I found it.

This is what I want to see
Both machines are great I love it
The Komatsu has obviously wider tracks. Less slippage but far harder on those expensive undercarriages. Also a newer machine by 2-1/2 decades.
Been a Cheeky New Zealander here but I was told mate the other day cats can't back up over piles but Komatsu dozers can, I replied " why would want back up over a truck pile, when you normally would just back around it and push it out" . Komatsu lover my bro is😉
Komatsu 💛
thanks.
I run a 96' 155 with 15,000hrs alongside a new D8T last spring and out ripped him in a hard rock borrow pit, Komatsu have always had a better ripping dozer and better blade design on virtually everthing they make. Notable exceptions for me were the 135 and the 58LGP, both P'sOS and not made anymore. I know some owners that have done very well with Komatsu since the 60's (After the cat dealer screwed them on parts) ...So it goes both ways.
Also look at the angle the guy on the cat is running his ripper at. He's plowing instead of ripping. This video may be impressive to those who dont know what they're looking at but operators know whats up!!!
MrBiggreedy ur exactly right! I noticed that to all he's doing is wearing out his tooth and he's got all his weight on the front idlers.
Yes sir ripper isn’t even curled
Mmmm, I thought that it needed adjusting, as you can see the angle was all wrong, surely they would have noted that?
100% on the money there
Well I'm saying one shank isn't assisted by two and the adjustment on the cat is poor
I have worked with Cat and Komatsu bulldozers in my works. My experience is that komatsu dozers ripping better than Cat dozers. I think is the design, Komatsu has more distance from ripper to the front wheel, it gets to be more punching power.
The old version of cat such D-9 is strong as Komatsu, but the new version with high track are not, because its doesn't provide the strong ground pressure, only good thing about high track is to keep the dirt out but not the pushing power.
Wrong. The d9n series CAT dozer have the high track and have 71.9 metric tons of drawbar pull. The kom in the video only has 66 metric tons of drawbar pull with the low track. The cat also only has 10 more hp than the kom making it a better machine.
The cat have 10 more hp than the kom but its useless and probably more expensive as well. There two good things about high track will last longer on the track and keep their dirty away, but if you want the power and get the job done quickly low track is the answer.
The Cat high drive simplifies and strengthens the transmission. This durability advantage is well worth the increased length of track.
No no creo que sea más potente talvez un poco más rápido
komatsu for the win,built in Japan,reliability,economy,dependabilty,CAT parts are nearly all Chinese
i seen a 1967 caterpillar wheel loader, tag said made in japan
Muy lindo video, que maravilla de máquinas las dos mejores del mundo y sin desmerecer al resto...
Que hermosas maquinas y son las mejores del mundo
Both are good, I cannot say which one is better.Komatsu is reliable and easier to handle.Caterpillar is strong, durable, and solid.And both brands are much better than any Chinese made tractors.
Hmm maybe not but the Chinese are turning out some good strong trucks now ,,, not big HP but can carry a load,,,
Japanese made
Komatsu = awesome
Komatsu D155 / HP-354 / Operating weight - 87,100 lb
Caterpillar D8R / HP-305 / Operating weight - 73,850 lb
Kinda like racing a Mustang and a Viper. Both cool cars but not a even lineup.
pretty obvious many comments are smart and more are dumb, written by someone who didn't read any other comments. I've been an operator for over forty years and I learned a lot reading thirty comments. Currently a Cummins powered truck operator
I love these two bands
boys just admit it! the komatsu kicked her ass! and i own a cat myself !!!
Buena máquina Andres
It's now 2012, how is the Komatsu doing now? After sale dealer support still good?
Wonder which dozer would win a push off dozing against each other, Cat D8R or Komatsu D155A-6? What say we find out? ;=]
That's the evidence why Komatsu is the Best!
the operator always makes the difference,I saw a Cat ripping with two in the ground with the thing dragging dirt deep it had no problem .here the hydraulics were set at different angels to the ground and depths here as another posted the Cat was not set right.
Its like watching two snails race, they are slow no matter what, why does it matter if one is just slightly faster? They both will get the job done at the end of the day.
I've heard over and over from guys In the industry, when it comes to parts availability, downtime, repairs, lifetime use, it isn't Komatsu. They rip well. That's it.
if you wanted to use a dozer solely for stockpiling sand, which one is the superior? Please would really appreciate your thoughts?
Sand is high in Silica !!! get ready for high track wear !!
Thanks Tod!!
If youre dozing Sand , have a look at John Deeres Speed Dozer - a Quadtrac on Rubber tracks! they have replaced Conventional dozers on I think it was "Fly ash" stockpiling due to high track wear on the conventional dozer
The Cat's ripper is a lot bigger than the kamatjunksu...Cat is King!!
I like both.
I used to push a D8L out with a 455 when the 8 got stuck
I mean the track mover, the hitrack is good to keep the mud out but its don't give enough strong push as the low track
The 475 will out rip the D11 in permafrost with its superior traction
The Cat highdrive loses track on ground during ripping. That's why when he forces the ripper down, the tracks start to slip. The ripper mounts to the machine in front of the rear idler on the Cat so the back of the track lifts when the ripper goes down.
Claramente esta demostrado que KOMATSU es la mejor maquina del mundo, la tecnologia japonesa en este caso en la fabricacion de maquinaria pesada es la mas fregona que hay.. simplemente, el bulldozer mas grande del mundo es KOMATSU.. Que tal eh??
Caterpillar no tiene nada que hacer aqui....
which machine cost more?
Komatsu 3سيوف ومنزلهم بالأرض أكثر وتغلب على catوالله الكوماتسو جبار
Caterpillar equipment is the best
CAT makes machine toys for kids
CAT equipment from 5 years ago can still work
5 years ago? I work for komatsu and I'm still selling stuff for machines over 25 years old and still working.
I take it you have never been behind the controls of a machine...
@@mikethomas6408 your comment makes absolutely zero sense lol that low? Fuck i make a great living in dirt work
i agree a komatsu 155 outrip a cat D 8 cat is balanced and komatsu weight is att the rear . but this comparison is not fair , the cat is at the top of the hill where there is no soft soil on top of the harder material . cat is in the hard rocks . so please compare apple with a apple
Those komatsu machines even the smaller ones are ripping beasts weight and horsepower always wins
Parts and service. ? HMM not where i live in TX.
Did Caterpillar have a response to why theirs didn't perform as well?
Each machine has it's benefits, i run a d10 and a komatsu 375, controls are less fatiging on a d10, komatso more quiter, kopmatsu has digital display with built in camera and a you can select recirculating air, the 10 is better for crushing rocks, 10 has better cab with more room to keep your junk and you can see the bottom of the blade. Komatsu brakes don't grab so hard or shift gears as rough becuase of the damper. You run either enough you start to like one.
There is a difference in the length of the Rippers. One had three that was shorter. The other one had one that was longer. Grabbing into heavy Rock. That's the difference. And at the end of the day it really didn't matter. One of them tears up big rock. And the other one digs up surface rocks. Totally different Rippers
There is so much lack of info in this video. That cat had over 15k hours on it. The cat was a 90's and the komatsu was brand new.
Interesting stunt, and convincing to those who do not understand the application. Why didn't you let the Cat sink his shank angle in? Why is the D8 ripper shank longer? Why is the center shank on the Komatsu shorter?
I wonder how long it took you guys to layer the right amount of fill to keep the Cat in the rock and Komatsu in fill.
Interesting stunt. You should try it again with rippers of the same depth, and operators who know how to rip.
@KOMATSUIRONM4N I found parts to be over expensive? Poor availability of aftermarket parts? What models are built in the USA? I paid $1000 per hole for pistons and liners.....its not an airplane engine I thought?
Hi, Folks.
It is interesting to read all these comments - - - and NOBODY changing anybody else's opinion. Fight, you dummies, FIGHT. I 'HATE' peace.
Firstly, the Cat is quoted as being a D8R, which is only about 285 HP, NOT 305 HP like the newer D8T. It is also LIGHTER than the D8T, hence less traction. Pitted against a tractor with another 70 HP and probably close to TEN tons more weight? With that in mind, just what would common sense tell you might be the expected result?
And then add in the 15,000 hours that the Cat is said to have already done.
I am open to correction here as these figures are off the top of my head but I think they provide a more accurate picture than some are painting here.
Just my 0.02.
You all have a wonderful argument. Best wishes. Deas Plant.
We run the komastu 375s and the 475s then we have a cat D10R and Cat D10T. Yea the komastus are heavier which gives them better traction but but them both on a high wall or a sloping project and see who comes outon top. Cat by far is better equipment the komastu. Also run the WA1200 loader and the cat 994 which is an old run down machine will run longer harder and produce the same tons and its a smaller loader
very nice race,
komatsu without any doubt is the winner.
i enjoy the power of komatsu.
Don't know what is wrong with the cat dozer wrong gear or wrong operator cat was a disapointment kamatsu seemed too have more power
Take the Komatsu cab and controls and put them on CAT and you'd have a hell of a machine, The biggest and most important difference is H-track vs L, the H-tracks beat you too death. 25yr Dozer operater currently on a CAT D11.
i work at a wood chip power plant and we have 2 d8s and a 155ax the 155 is quieter and more comfortable but thats it it overheats after about a hr of hard work id wont turn with a full blade of chips its slow but the radio is nice in it. the cats are louder but run cooler breakdown less and will climb and push like no other. ive gotten the 155 stuck and slid it off the side once the cats hold there ground and have never been stuck but they have pulled the 155 out.
Aí é duas feras. Quem tem conhecimento é eu. 😂corto na alta. 😂
I ran a d6 for years and and if I ever tried messin' around like this, my luck, I would have hit a waterline, lol!!! Cant beat a cat
Yes you can komatsu proves it everyday.
@markdmy Wrong, that is a series II
I have both of theses at my work. My brand new Komatsu is terrible. Overheats a lot Can’t take the work load for a 8 hour shift. It gets wash daily. Trying to help it stay cool.
thats normal for Komastu
The cat operator didn't pull his shank under him. He's dragging it through the ground not ripping it through.
You can't compare cat to komatsu. I use to operate a komatsu d155 ax - 6. WHAT A BEAST!
Komatsu🤩
Are you kidding! While we are at it why don't we get a D575 and let it push with a D9. Some of the comments made are ridiculous. The point of the demonstration was to put the same class dozer up against each other. That's what we did and the results are obvious. That's why the customer purchased the Komatsu.
Look at the clear hight difference. Komats is almost new.
thanks man!
Komatsu is the Land Cruiser of the heavy duty trucks

The elevated sprocket concept was more for aesthetics effects but believe me it does not improve the tractive efficiency of the machine. Its more costly to maintain.The earlier Cats with regular tracks were class. Komatsu on the other hand is much simpler in design and more efficient. I recommend that Cat return to the regular track design and drop the elevated sprocket!!!!"Half is better than quarter".
Looks like they took your advice lol
a posição do escalificador do d8 esta errado , esta trabalhando com cilindro todo fechado levantando a traseira do trator , e fazendo que a máquina tenha mais atrito ao escalificar.
@rogueorange
And in the CAT it comes with a special option.. Fuel consumption.. While the Cat is drinking at the pump, the Komatsu will be still out working.
At the end of the day, both very impressive production machines...
@jaredjohnson1977
Any idea why Cat chose to have a 'high-drive' final sprocket?
Am wondering whether there might be a distant parallel between say, a Honda Accord and a Cadillac DTS (feel's quite different behind the wheel)?
depends where your located...4-12g's
Komatsu 💪💪💪
i run a D8r in a gravel pit ,affectionately known as the dirty deed, god only knows how many hours it has, still going strong i looked at the 155 komatsue at a dealer nice looking piece of iron! just wonder how it would hold up at 20 thousand hours
Hai thương hiệu số 1 trên thế giỏi
I'm not sure what you're basing your statement on, 915600. The coal mines at Grande Cache and Hinton (Alberta Rocky Mountains) switched from Cat to Komatsu and found less repairs, lower fuel consumption along with better operator satisfaction going with Kom over Cat.
Look at how wore out the tracks are on the D8 and also very old compared to the Komatsu.
if the d8 was a k series , that would have been excelent
your 100 percent correct about this operator. the longer he uses the ripper at that pitch the worse performance he,s going to get from his tractor as the boot rounds off & goes blunt. the 155 would still out rip the 8N but not to this embarrising extent.
apples, meet oranges..
Einfach die Beste
CAT is our brand though, save the nation
I think speed is an overlooked stat in a dozer lol.
Haha funny to see all the cat-fanatics support their machine. I myself know very well as a salesman that the D155 has way better fuel consumption and part prices. Komatsu Rules!
Enkhtsag Damdinjav you are so full of shit. Komatsu’s are only good for overheating and having computer issues.
Komatsu is the best for me...
Which tractor weighs more?
The Komatsu.
Cat like Honda might not be the fastest or strongest but by hell I bet they'll out last everything else
I've operated both in rock and I'll take the flat track, more powerful KOM any day.
Sorry... I made a typo. The former should have said 'fan-belt pulley' for $1,100.00 +
Very power full komatso dozer D155 Ax-6 than cat d8r China made. I was operated D155 EX -6 before in Philippines
We "had" 4 komatsu D155's, compared to the Cat D8T, there was no comparison, the 155s wouldn't stay running long enough to keep up with Cats, junk in the real world.
+Collin Morgan I bet there is more to the story
I work as an FSO for a power plant, run 3 Cat D8 continuously. We tried a new Komatsu and the damn thing had more computer/overheating problems. I’ll stick with our old D8N over any Komatsu new or otherwise.
And your full of bullshitt..
@@mikethomas6408 just sharing our personal experience, you're a bigger piece of shit than the 155's. Tool
@@mikethomas6408 Lol, you're just another little keyboard warrior aren't ya
@HomebrewCigarsmoker Well said.
Komatshu es komatshu todo el tiempo
Yall were using a new dozer vs an old one. Why is that? An N model cat dozer has more drawbar pull than the R models. Drawbar pull = better ripping ability. They also have less power and weigh less. Let's see a Kom go against it. BTW I'm a deere guy
Komatsu is the best dozer.
Again, do your research. Komatsu offers a Parallel linkage system as well.
The D8 has a nice purr to it though.
You can’t beat a komatsu machine
Caterpillar is my favorite a D-9
look at the grouser bars on the 8. Put new pads on the cat like the Komatsu has and then lets see.
Film the operators swapping tractors and then swap the tractors over on the return pass and i might be convinced, until then blah, big deal, there are so many variables in ripping and the jockey is one of the hugest.
You should see a 475 rip circles around a D11
Like they're, comparable...
Mam I sure would like to learn how to operate a dozer. I thought I had found a guy to teach me, but he didnt bring me fuel and ran me off I got 4 hr of run time. till the dozer ran out of fuel.and the got pissed..so I'm thinking of going to a school.any one know how much it cost to go to a school to learn
I run a cat D8R everyday and it has the 3 shank rippers and I can bury it all the way in any kind of rock and dirt I've ran the komatsu a lot to and I hate it I'd pick the cat any day
Parece que o D155 leva uma pequena vantagem, provavelmente por ser um pouco mais potente.
Entao mas o 155 leva 3 bicos na terra e o D8 só leva 1. komatsu power
😂😂
