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 last time I used my slide rule was in the 70s , as a straight edge when cutting wallpaper for a closet. In Dortmund Germany's unions priced themselves out of the market and shuttered the factories with the big shovels now made the USA.
That's awesome that you have some old school sliderules that were actually utilized... Would be awesome to see and especially to have models of these kinds of units... Especially models you can't source any longer
I'd love to talk to a guy like him. Make sure you get as many stories from him as you can if he's so inclined. No one lasts forever and when he's gone, those stories go with him. You never know how solutions to problems he had faced in his career may apply to something in your life, even if you're in totally different fields.
@@deconteesawyer5758 it's crazy, imagine what people with these skills and willingness to get the job done (no fear of Health and Safety BS) were working today with all the advanced technology etc, loved seeing that guy checking plans for dimensions while having a smoke 11:34
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.
The RH400 was a very successful design, it outlasted O&K who got taken over. I'm puzzled as tonthe subsequent lineage of these as both Terex and Cat offered them, yet New Holland are stated as having bought O&K? Ian Cummings voiced so many industrials, he was the go to v/o artist, especially German companies it seems.
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.
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.
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.
👍👌👏 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.
The design of this machine started before 1995, and was built heavily on the designs (and engineers) that made the previous machine in 1979. Many companies at this time did not have computers any more advanced than Windows 3.1.
Agreed, I was also surprised to see the video is from 1998. Nonetheless, I thoroughly enjoyed the entire format that was used including the music, graphics, voice-over and copy write.
@@beefchicken no idea, read it in a book I have , the new cylinder was flown over from Germany,to Canada,before anyone noticed I guess , massive digger. Love to see one .
There was a larger one built after CAT purchased Bucyrus called the 6120B. I believe it is still on display in the States, and the second one was built for Shell in Fort McMurray but was never finished for reasons. I believe that was in 2015.
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.
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

Beautifully engineered machine . The Germans do some of the best engineering in the world .
Yes. Bastards practiced on tanks and other weapon.
Nobody does engineering quite like the British
All learnt from the British
I drive a BMW, the germans take 9 steps when 5 would get the job done. German engineers are in love with their creativity.

A work of Art. A Monster dual engined hydraulic Powerhouse. 🤙
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.
I am not familiar with Cable and wheel excavators, why do you feel like that is the case?
@@mbox314 Otherwise known as draglines....

Thanks for sharing this video. This is very interesting and learnfull! 😊
Very detailed! Thanks for the video!
And in 1999 it was sold off to various entities ending O & K.
bro that intro SLAPS 👏
20:49 sooo are we just going to ignore that it's leaking oil in more than one place just in this shot?
my thought exactly
that's why they assemble it first at the factory to assess any problems 👍
It was a good leak, but if that's the only problem, that's pretty darn good.
I don't think that's a leak it looks more like a wire these a couple of them all over the machine I'd assumed they are for computers for testing.
@@mikethebike5014 I see something hanging down, I wasn't talking about that, you can see oil on the cylinders. I'm sure it was something minor.
Wonderful video. Thank you for uploading it!
Amazing video, so much detail, I have a book,showing the assembley of the digger,
Each hydraulic cylinder delivers 477 tons of force. Holy Shit. 🤔😳
That should split a log. 🪵 😂
80s and 90s. The quality excellence eras.
My O&K RH9 is a baby compared to these. I would love to see any factory video of the smaller machines being made.😀😀😀
24:27 Make that as low as minus 52 degrees Celsius , I've worked up there 😨
Thank you for this video, very interesting.
I would like to see how they went about fixing problems that arose. In manufacturing that is the key. Something always goes wrong.
what a wonderful video, thank you so much for sharing....Paul in the US, Florida
production. Thanks again!
How many hauling trucks needed to transport this massive machine when disassembled?
Where do i find this amazing music

Funny how back then it was tested there and not on the actual mining site. Double build.
8:53 No way!😮
That was really interesting, thanks.
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,
Is that why during disassembly everything looks like it's covered in oil?
@@beefchicken no idea, read it in a book I have , the new cylinder was flown over from Germany,to Canada,before anyone noticed I guess , massive digger. Love to see one .
Does this factory still produce the Cat version of the RH400 ?
"The construction-equipment business was sold to New Holland Construction, at the time part of the Fiat Group, in 1999" - Wiki
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! 😆
Nah, they planned that, thats where the 3% inefficiency comes from.
I work on heavy equipment but nothing like that/ absolutely amazing
When you pull the pins does the load get dumped on the crane and go wildly careening around like 21:55 ?
Used to work on these beasts in Western Australia
When are they gonna make a really big one ?
There was a larger one built after CAT purchased Bucyrus called the 6120B. I believe it is still on display in the States, and the second one was built for Shell in Fort McMurray but was never finished for reasons. I believe that was in 2015.
This thing still in operation?
Great video❤️
Thought that was Bubbles from Trailer Park Boys in the thumbnail
That’s one hell of a handsome machine 👍🏻
It’s amazing that quite intelligent people assume that inane beat music is an essential factor in advertising.
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.
very disappointing
Where is production now Dortmund is no longer?
@@05clenharth The diggers are now made in Indonesia and the build quality is terrible.
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 music in this video is insane
Did anyone else see John Candy working on the tracks? I had wondered what happened to him.
so like how much for one of this ?
Excellent video thankyou 👍👍👍
Did you get fruity or producer edition? Im looking to buy soft soft but i dont know if Producer edition is worth it...
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.
I came to see the mechanics, I stayed for the music.
CAT was smart to buy this company...
Music bed's a little loud, eh?
Surprising now to see factory workers without helmets, etc.
Not all countries can make this wonderful machine
Masterpiece Presentation
How many of these were ever built?
I know of 22 of them across various generations of design.
Wo habt ihr denn die VHS Kassette gefunden? 😂
Massive operation 👏
LOVE this video...
Still using 80s music in a late nineties documentary😨
This model, the Komatsu PC8000 and Liebherr 996 are my favorites!!!!!
This machine is a fast way to load trucks.
Is that Skippy in the thumbnail?
And then Caterpillar bought them up, now O&K does not existt
Who else thought that was bubbles from the trailer park boys in the thumbnail?

Also, (didn't realize at first, but) of course these are Germans xD
This marketing video must have worked as the company was sold in 1999.
Why is bubbles in the thumbnail
Anyone else catch the oil come leaking out of that hydraulic cylinder at 20:45 ??
Or maybe more like some grease stains in cylinder?
Does a warranty come with that?
yeah
Truly amazing
I wonder what happened to syncrude in Canada and the rest of the Canadian oil mining industry
Oil sands are still going in Alberta, expanding considerably,
is that Benjamin Franklin on thumbnail
Just incredible engineering

11:33 smoking on the job? How old is this video?
From the description 1998....
Nice machine Great pity about the bloody music.
I agree with you
20:48..something is dripping on that cylinder....
I think CAT bought O&K?
O&K was already bought before Caterpillar did
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
Depends upon which country you are from.
constant brain numbing music noise ruins this very interesting doc
Shovel not excavator

Super video of an amazing machine, but it would be a lot better without the totally unnecessary beaty music competing with the narrator.
Can anyone figure out what is missing in this video?
