It never ceases to amaze me the things men do... We keep this whole show on the road...Cheers to those that risk life and limb daily, becomes just part of the job...Respect!
15:07 ... You can see the specific O&K "triangle" where there is the 2 jacks and a rigid bar to the frame. Like so , a part of the right jack is communicated to the frame. Interesting choice of O&K many years ago. The big CAT showels from now are in fact O&K with a cat paint. O&K was sold and sold... Just the name changed. So, very big Cat are made in Germany ... And all Liebherr "caterpilar" excavators are made in Colmar, France.
Did anyone notice the Flintstones T-Shirt at 10:40? I thought it was funny that as they are putting this machine together in a quarry wearing a Flintstones T-Shirt.
Hi Duncan, that was a great job 25 years ago! I´m grateful that you helped me so much to make this video. I hope you are okay. Are you still living in South Africa? Give my regards and stay well, Timm
Like how their all pinned together so u can move it in future this is how are crains come beinh a iron worker same thing istead this had a arm instear of 300' boom
You noticed that too. If those pads are 4 feet long and 1 foot wide they would have to be 12.5" thick in order to weigh a ton. They seem a little shy on those dimensions.
@@scootertramp4355 Your forgetting each pad is at least 48" or more wide and far more than 12" long, there's also the track rails, pins, bushings, pad bolts etc. This O&K looks to be roughly the same size as the Hitachi 5500 I ran and probably a ton for each pad would be about right. These are now only about mid size for hydraulic shovels though. Size wise there nothing special. Surprisingly these O&K's seem to be a pretty close copy to the 5500 including the deck mounted secondary crane. The one I ran had twin V16 Cummins which I think is much better than the electric drive from an operators perspective.
@@S70AMG I'm not making assumptions. I don't know if O&K were making hydraulic shovels prior to Hitachi doing so because I've never bothered to look into that. I'm guessing from what you've said they were. But what I do know is the 5500 I ran was the very first shovel of that size Hitachi had built and it had a factory installed placard in the cab that said at the time it was produced it was then the worlds largest hydraulic shovel. It was sold to Suncor in Alberta and the mine I worked for bought it from them. So yes since it was the first of that size, then a pretty close copy would probably be good enough for most people. It was maybe not the best choice of words to use, but I didn't realize at the time I made my comments this was going to turn into an English Lit class.O&K may well have come up with whatever design similarities there are between the two machines on there own for all I know, or Hitachi copied some of the design from smaller machines from other manufacturer's. It's a meaningless obscure detail and really not important enough for me to bother looking into or care what they did.
@@turningpoint6643 o&k was one of the first major excavator makers and the biggest one to have ever exist. When hitachi started mining equipment , o&k mining department had been sold to terex. They manufactured the biggest excavator , the rh 400 which now is the cat 6090, the powerless piece of junk
@@maxime121 разговор идёт о повреждении покраски. Деревянную прокладку применяют для сохранения целостности металлических деталей, но, ни краски на этих деталях. А вот что бы не тронуть покраску для этого применяют специнструмент для запресовки/выпресовки пальцев.
Уралмаш шагающий делал по крупнее, этот самосвал ни с одного ковша загружает и вылет у него смехотворный. Пока не собрали думал моща, как собрали - какой-то игрушечный
@@maxime121 Тут вроде как африканскому зверью посочувствовать хотели. И в тему ты? А, ну да, на Урале зверью веселее было - ты, видимо, это хотел сказать.
@@alysongr How else do you want to drive that pin home? In the other areas of the assembly operation, they use a medium-sized wheel loader as a pin pusher, that has 500x the amount of force. What are you afraid of happening by driving the pin into the bushing?
