My Grandfather was an Engineer in Dortmund at O&K. He still has Models of all kinds of the excavators of O&K in his Home and he loves to tell about his work. When he retired they started using Computers, he was used to do all the calculations by hand. He gave me all of his sliderulers which he used during his engineering career which i treasure. This excavators was finished in his last year there.He is getting 97 next month.

The quality of the hydraulic excavators manufactured by O&K is second to none. Many of the units they made are legendary in the heavy construction and mining industry.A great example would be the RH 120C. I can’t think of a hydraulic excavator with a more stellar reputation. The RH 120C was absolutely loved by the British mining industry. The machine was available in either backhoe or shovel configuration. Another outstanding machine made by O&K was the RH 200. The company produced many great hydraulic excavator models. When O&K engineers developed the incredible TRI-POWER linkage system, it was a game changer. In my opinion the development of the system was an act of genius. Keep in mind that TRI-POWER is still in use on the most modern, state of the art CAT hydraulic excavators.Many thanks to U.K. TV-Dortmund Videos for posting this awesome video.Excellent job on the video production.

Surprised at how much I enjoyed this video. Seeing the machinery used to make such huge parts blew my mind. The thing is so huge my brain was surprised when a person was next to the equipment for size reference.

Beautifully engineered machine . The Germans do some of the best engineering in the world .

I've had a try of one of these in the UK. They're just massive brutal machines and yet have such fine control over their working. The sheer size of them is astounding.

I have two of these where i work and they are a true power house and an honor to operate. Thankyou for the play back from back in the day.

A work of Art. A Monster dual engined hydraulic Powerhouse. 🤙

This machine makes my 52 HP tractor look like a toy. If this excavator was digging on my farm it could demolish a few hills to make my farm a lot flatter. That would be good.

An 80 ton counterweight. What a beast !

This video has helped me to understand why cable and wheel excavators are more common than hydraulic excavators at this capacity and size.

Great video. That's one hell of a machine. You know it's a big milling machine when there's a catwalk on the cutter head with room for a tool cabinet and a chair 7:03. Thank you.

It’s amazing that quite intelligent people assume that inane beat music is an essential factor in advertising.

Thanks for sharing this video. This is very interesting and learnfull! 😊

some sweet 1980's-90's digital graphics and txt, the memories, hah. Reminds me of the education videos we watched in middle school

Each hydraulic cylinder delivers 477 tons of force. Holy Shit. 🤔😳

Very detailed! Thanks for the video!

Amazing video, so much detail, I have a book,showing the assembley of the digger,

And in 1999 it was sold off to various entities ending O & K.

Wonderful video. Thank you for uploading it!

20:49 sooo are we just going to ignore that it's leaking oil in more than one place just in this shot?

My O&K RH9 is a baby compared to these. I would love to see any factory video of the smaller machines being made.😀😀😀

Thank you for this video, very interesting.

24:27 Make that as low as minus 52 degrees Celsius , I've worked up there 😨

I would like to see how they went about fixing problems that arose. In manufacturing that is the key. Something always goes wrong.

👍👌👏 This device and the video is absolutely fantastic! But it looks definitely older than being out of 1998. I never thought that a big firm still used an old school overhead projector and no laptops while having conferences in 1998. Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards luck and health to all involved people.

production. Thanks again!

Funny how back then it was tested there and not on the actual mining site. Double build.

what a wonderful video, thank you so much for sharing....Paul in the US, Florida

I watched this entire video, how did you guys produce this to capture the attention of the viewer? In the 90’s no less.

The first digger blew a hydraulic seal on start up, just before the hand over to the Canadian customer, it was quickly fixed with a new cylinder,

Great video❤️

bro that intro SLAPS 👏

CAT was smart to buy this company...

I work on heavy equipment but nothing like that/ absolutely amazing

Used to work on these beasts in Western Australia

That was really interesting, thanks.

Still using 80s music in a late nineties documentary😨 This model, the Komatsu PC8000 and Liebherr 996 are my favorites!!!!!

"The construction-equipment business was sold to New Holland Construction, at the time part of the Fiat Group, in 1999" - Wiki

I came to see the mechanics, I stayed for the music.

Does this factory still produce the Cat version of the RH400 ?

Where do i find this amazing music

Massive operation 👏

Excellent video thankyou 👍👍👍

How many hauling trucks needed to transport this massive machine when disassembled?

Not all countries can make this wonderful machine

That’s one hell of a handsome machine 👍🏻

Truly amazing

This machine is a fast way to load trucks.

The music in this video is insane

Thought that was Bubbles from Trailer Park Boys in the thumbnail

Masterpiece Presentation

I was interested so I looked O & K up…defunct! Company was broke up and sold off in 1999 ! New Holland bought the construction equipment branch.

Did anyone else see John Candy working on the tracks? I had wondered what happened to him.

And then Caterpillar bought them up, now O&K does not existt

LOVE this video...

8:53 No way!😮

Surprising now to see factory workers without helmets, etc.

8:17 an efficiency of 97% calls for maximum precision.... Which went right out the window when the mechanics banged the gear on the seal housing! 😆

im 0% surprised an oil company bought this

It is such a shame that Caterpillar decided to move manufacturing of these machines to South East Asia and the quality is now so poor that weeks of reworking is required when assembled. There is no quality anymore.

Just incredible engineering

Did you get fruity or producer edition? Im looking to buy soft soft but i dont know if Producer edition is worth it...

Who else thought that was bubbles from the trailer park boys in the thumbnail?

Great video1

is that Benjamin Franklin on thumbnail

I'm starting the first year of study for mechanical engineering, if i ever get to work on designing something like this it will be hella worth it. Also, (didn't realize at first, but) of course these are Germans xD

When are they gonna make a really big one ?

This thing still in operation?

Wo habt ihr denn die VHS Kassette gefunden? 😂

This marketing video must have worked as the company was sold in 1999.

so like how much for one of this ?

Music bed's a little loud, eh?

Как у нас на УралМаш Заводе!

Why is bubbles in the thumbnail

Oh how I would love to play with this thing

I think its called final drives and planetary gears not travel gear but still a grate video and as outhers say shame about the awful music

The irony is that O&K went out of business the year after this video was made,

How many of these were ever built?

maximum precision then proceeds to show the guy just slamming the part in the bore

Are these available for delivery my address ?

Super video of an amazing machine, but it would be a lot better without the totally unnecessary beaty music competing with the narrator.

Once upon a time...

Anyone else catch the oil come leaking out of that hydraulic cylinder at 20:45 ??

Does a warranty come with that?

Is that Skippy in the thumbnail?

They keep focusing on Africa… like Africa ever produced anything other than mud huts and super viruses. 👍🏻

I wonder what happened to syncrude in Canada and the rest of the Canadian oil mining industry

Where is this model made now, Germany or the U.S A ?

constant brain numbing music noise ruins this very interesting doc

Can anyone figure out what is missing in this video?

Shovel not excavator

Wow.

Nice machine Great pity about the bloody music.

$11 million each,

20:48..something is dripping on that cylinder....

Bubbles!!

11:33 smoking on the job? How old is this video?

I think CAT bought O&K?

Nice, but I’ll stick with my Hitachi Ex8000. Also comes with a microwave oven and a some kind of smelly shoulder Hitachi massager that the previous female operator left

German engginering!!!
