Cat only added a few tweaks that tipped the scales past 1000 MT, the tech and ingenuity will forever be from O&K with the combined effort from Syncrude Canada. Legendary forever
The very first O&K RH400, Syncrude fleet number 11-35, started work in August 1997, it weighed 830 metric tonnes and carried a 42.5cu.m bucket. It was initially powered by a pair of Cummins K2000E engines producing 3350hp, but these were soon upgraded when the new Cummins QSK60 V16 engines were released the following year. Subsequent models increased in weight and power and today the Caterpillar version, called the 6090FS, weighs in at around 1000 metric tonnes. This Caterpillar version still uses the same twin Cummins QSK60 quad turbo 60 litre V16 engines, but by now they have been upgraded to 4500hp with a 52cu.m bucket. Both Terex and Cat made significant changes and upgrades to the original O&K design resulting in increased performance and reliability. Between 1997 and 2021, only 22 of these machines, both RH400 and 6090FS, had been built, an average of less than one per year with the overwhelming majority going to the Canadian oilsands and also to Australia. Citic Pacific's magnetite mine in Western Australia (as shown in this video) has four of these working, two started in 2008, numbers 9 & 10 off the production line, and they were later joined by number 14 & number 15. The very first RH400/6090FS produced in Cat yellow was number 13, it was shipped to a mine in Mozambique in 2012. (source : Earthmovers Magazine)
@@craigsibley8161 i wouldnt know the stats on that one , i worked on Godkin in the coal gang and remember the 300 and the Wabco trucks. I believe it ended up scrapped.👍

There is a very detailed and long explanationn in the comments column. And that is right
Bro what about 6120B Caterpillar?
I think at work you have different brands of mining equipment, it's amazing
There are indeed various brands of equipment but at different mine location, the work team moves to another mine location
I think the engine should be changed to be stronger
terex rh400 digger excavator amazing
The best excavator of all time 🤗
Huge trucks, I have driven trucks, but small sized trucks
Nice👍👍👍
Thank you buddy 😊
Cool face shovels 👍👍👍 in a league of their own... The heaviest O&K to work here in the UK was the RH200 ...
The two largest excavator in history are the RH400 and 6090 FS... but unfortunately these two highest types are no longer in production now
RH300 operated by Northern Strip Mining (NSM) , Godkin opencast site in Derbyshire UK in the 1980,s.
@@shanemcpherson1015 your right, forgot about that one. Wasn't the RH200 from the 90s heavier though?

Terek RH 400 and Caterpillar 6090 FS,,, they are the same.......just name changed...
Yeah because Caterpillar bought it 👍
Terex*......
Now Caterpillar is the owner of Terex...
Rh 400 they use Cummins engines total output 4500hp
Really a good tool brand from an operator station perspective
