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.
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.
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.
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 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.
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
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.
@@andrewrees8749 Not quite. Caterpillar bought Bucyrus and they are in South Milwaukee. Komatsu bought P&H and they are in Milwaukee. Caterpillar makes this shovel and it is the 6090
@@mkemachineinc.8058 aah yes,I got you, Illinois is the other place over your way, Cat are made, thanks for the information, I live in Wales, part of the u,k, did go to the minexpo many years ago in Vegas, seen some massive equipment. Seems my first Cat d11 .
Wow did u see the size of that guy's might torch...I think he's compensating for something..lol joking great work ...real Tonkas was also gonna say something about guys missing hard hats but I guess if it's not a bump on the head form you its not going to help...I figure if something goes wrong the hat ain't doing shit
