These have been in use in Japan for a long time. I lived in Japan in the 70's along the coast near Zushi . There was an old guy who had one of these machines and he would drive it up and down the beach from town to town cleaning out these mooring areas for the local fishermen. It was a lot of fun to watch.
Lots of people are saying that this is too slow or the wrong way to do it, that dredging would be better. But Japan only has a limited number of dredgers available. After the tsunami they had hundreds of harbours this size to repair and nowhere near enough machines to do it. Especially since many of those dredgers were also wrecked by the tsunami. So they did what the Japanese often do: they got creative and adapted what they had to hand. I think these machines are another fantastic example of Japanese ingenuity.
The D155W was introduced in 1971 and was the first amphibious bulldozer, a development of the first radio-controlled bulldozer which was introduced in 1967. One went to Chernobyl in the late 1980s. I wonder how many of the early '70s ones are still going?
Holy hell i was expecting to see an operator with a aqualung sitting in the seat operating it until i spotted the guy with the controller. Dammed amazing...
I'm right there with you. Dubai is probably a huge customer, with their reclamation projects of the sand shaped development and others planned and some completed, and visible from space. The time below is way too long to dive a day's worth, but why is the controller operator walking. Hell I'd be in a swivel easy chair, sippin suds, and doing wheelies. The only thing close to this in the fun factor, ,is the John Deere 764 HSD (High Speed Dozer). The coolest thing about it, is not the ease, (although put a rookie in in the morning, and he's a star by lunch with the toys attached auto leveling via gps etc) so much than the fact that it no longer tears up your fine grading by turning. Off topic possibly but still relevant to cool dozers, and exclusive abilities. This thing has got to be busy making deep water docks in rich neighborhoods like on the Inter Coastal Waterway in Fl.
Getting a sea monster vibe from these things 😳 the last part with it coming up from the water was very Godzilla, like fittingly for a Japanese machine, lol

because diesels and hydraulics are waterproof as it is.. alternate the cooling system and make the controls R/C seems much cheaper. plus theyre everywhere.
Nhìn chúng làm việc thật thú vị. Như những chú cua vậy. Nó làm tôi liên tưởng tới một vài bộ phim hoạt hình Nhật Bản. Tạm thời chưa nghĩ ra đc tên bộ phim đó

This seems extremely inefficient. Yes it is pretty cool but I can think of several different ways to accomplish that job faster, cheaper and better. Drag-lines and dredges come to mind right off the top of my head.
no doubt... a small 10" or even an 8" cutterhead... don't know why the trackhoes couldn't walk out there further before the dozers came in... looks real shallow

Only 36 of these were ever made
What I'd give to operate one of these beasts or have the opportunity to witness them in action! Definitely the peak of Komatsu engineering.

Bro these are nothing new. They were made in the 70s. It's not something they rigged together after the tsunami
Concept borrowed from WW2 era U.S tanks. Been around for decades.

What do you do for a living? I drive a damn bulldozer submarine now buy me a beer.
but, it's remote control, so is it really worth a beer? My 7 year old has remote control cars I don't buy him beers.. ;) lol 2:23 shows operator...

Only in Japan .What an outstanding idea
love how they are wearing hard hats. XD
bahaha... good one.. in case they fall in
I did this job for a while in the sea of Cortez. It's not a bad gig but it takes a long time to be able to hold your breath that long.
Lmao, bullshit, they're remote controlled.

😂 Muly fist impression too
Kind of steampunk, like something Captain Nemo might have.
It is 1968 that it was developed
I operate it by remote control
Wonder if you can hear the backup alarm underwater? LOL
It was changed to a sonar signal to warn the fishies
Can probably hear it four miles

What a great idea. An expensive idea...but still a great one.
Why expensive?
They need to do that in the Susquehanna river in central Pennsylvania.
Oh you have an R/C car? That's cute.

You need to get out to underwater construction sites more.

at 4:01 to the back right rear of the machine it looks like a seal popped up to the surface and then submerged again ! what do you think ??
dude you are right!!
Coolest thing I've seen all week!
Perfect for Patrick when. Squidward blocks access to his rock and won’t let him build a new road to get there.
I thought his last name was Star, not Heemeyer?
There may be underwater cameras that allow the operator to watch the blade's loading.
Awesome 👍🙏
Wow! What a cool Machinery?... I like it!
Wow!! tractores totalmente sumergibles!!!!
Amazing machine
does it come with sonar, and a fishing pole holder?
how is this controlled? by remote control?
Hollywood: "Okay, let's re-shoot Dante's Peake, only instead of a Suburban with a snorkel, we'll work in an underwater bulldozer. Hear me out..."
Super!
えw何これｗｗｗｗすごすぎる。Komatsu好きになった
I remember seeing these in a book i had when i was just a little kid.
これは凄い、
こういったものは、採算度外視で、公的支援を入れてでも開発成長して欲しいものだ。
I could make a fortune digging clams with that beast !
Dude these things r awesome😱💯 i want one🤣
Wow....!!
I hope the fuel cap is on tight.
Only 35 of these machines were ever produces

😂😂😂
where is it? donde es?
こういう作業は普通浚渫船がやると思うけど、たぶん浚渫船が接岸して土砂を荷揚げできる設備のない小さい漁港や一面に浅く埋まりすぎている場所では有効なんだろうね。
that was pretty crazy
My ass thought the operator is under there also lmao
is the engine air cooled
Probably.
i think is water cooled , like a marine engine.
Eloy Fernandez It was a joke of cause its water cooled it`s under water ! lol !

開発は半世紀近く前の1968年。

For when the zoning board hides underwater
うわぁ、なにこれかっけぇ

Underrated comment
How does the operator hold their breath so long? 👀🤔
Whoa.
KOMATSUすげぇ…！！！
ところでこれってリモコンなんですかね？リモコンだった場合、何も見えないのに作業できるってスゴイ事だし、乗って作業するなら、それはそれでスゴイ！！
いずれにしてもスゴイ（笑）
リモートコントロールで、水中カメラが必要です。
fucking awsum job Komatsu!
You cant see down there so how do they know what they`re doing?
willythewave it is rc they are sitting on wall
I bet they don't overheat.
Looks ilike they are radio controlled. And this is in what whay better then barge with excovator on top?
Nice would that work for gold dredging
Some underwater shots be nice,Japan ain't worried about the epa
I want this job so bad! :O
They are dredging the entrance making it deeper.
they call him...........SNORKY
@mieofujino 防波堤にいる方がリモコンで操作しているようです。
China Mieville's "Covehithe" from 2:09
How do they know what they’re doing underwater? Are there cameras fitted?
I doubt there's cameras - you wouldn't be able to see anything with all the silt being stirred up.
Skilled operators I guess.

This seems extremely inefficient. Yes it is pretty cool but I can think of several different ways to accomplish that job faster, cheaper and better. Drag-lines and dredges come to mind right off the top of my head.
Larry Poston Dragline is the proper tool, or extended reach excavator on flotation
Larry Poston Engineering an underwater bulldozer is also a lot of effort. Theres always a reason people do ridiculous shit like this.
Derrick Blackburn I agree.
Larry Poston probably too shallow
Derrick Blackburn yep, like being bored with 8 mil in the back pocket.......
only in Japan!
A dredge would be more suitable for the job, lol.
StormLaker1975 Go and rent one for them to use you bitch!
no doubt... a small 10" or even an 8" cutterhead... don't know why the trackhoes couldn't walk out there further before the dozers came in... looks real shallow
Storm Laker is mad
Me-So what do you do for a living?
These guys-play with remote controlled dozers underwater
Me-yeah ok
Me after the vid-well son of a...
seems like it would contaminate the water if there were to be a fuel or hydrolic leak
Just found out its Remote Controlled.
Nahuel Mariansky
yeah thats the hard workers sitting on the wall!
Rod Halstead LOL!!
R2D2's bigger brother
Seems like a dragline or clamshell would be more productive here.
ese things operated??? Remote or is there someone jammed in there???
rottysaurus remote
Someone needs to learn how to operate an excavator...
How do the operators hold their breath for so long??
+SMGJohn Lighten up, John, it was just a joke... : )
Good stuff... I did watch a vid showing bulldozers working under water.
Its like something from the mind of Dr Seuss but real.
The machine is really cool, but the process they are doing is inefficient. You need a dredge.
Thomas D Harrell How do you know what and how they were doing!
The internet is so full of miserable shithouses like you!
Jesus!
Dredge is expensive & logistically clumbersome & inefficient
And then it breaks down under water ?????
stick a tow line on it & pull it out & onto dry land..not a problem...
It would be more efficient to have someone in scuba gear operating it
Wow
I’d guess a cubic yard a minute tops. But mob-demob damned cheap. Rare ground that a crawler can work underwater.
Probably couldn’t see shit.
Since the tsunami, they've never been busier...all 5 remaining machines were fully restored & rebuilt...very efficient dozers...
Estoy con lo que dice Larry Eso es en extremo costoso e ineficiente Mejor seria una dragalina ,o una dragon Ellicot
yes, but why? that is my only question why
So is there someone inside or is it remote controlled? That would be claustrophobic as fuck if you have to work in that thing
This is not fun, this is disturbing. He doesn't even see what he plowing.
Murdika
Im pretty sure they didnt forget the wiper blades
Hahahhahaha
buldozer per lavori subacquei ,ottimo non li avevo mai visti prima ......dove stanno in giappone
How is that EVEN POSABLE
すごい
Безпилотники?
alguem sabe oque é isso!!!?
Looks like a very in-officiant use of fuel
I’m sure we could give you a shovel to do it with instead…. What’s your better way?
This is cool. any driver inside? how he can drive, can he see?
they are remotely controlled see the guy on the ledger there
Thank you Bryce, That makes sense.
