The Biggest Hydraulic Excavator in the World! CAT 6090FS/ O&K RH400 

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 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 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 picture of the RH400 painted in Bucyrus colours at 4:18 is fake, RH400 number 12 was built during their short ownership but by the time it was completed Cat had taken over, the shovel was painted all white with Cat branding and was sold to a coal mine run by Xstrata (now Glencore) in Australia. 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)

I was always fascinated - amazed by these massive machines. It amazes me with the amount of power they have and how the hydraulic hoses can hold so much pressure without blowing. The process as a whole is amazing

Ummm....It's name is Scavenger!!!

I usually dont watch videos like this with the artificial voice but this was pretty interesting

Hey, I'm an operator too so I thought I'd drop by and leave a comment.

There’s no doubt that the A I narrator’s voice is really aggravating in some cases, this is a perfect example!!! I was able to get through this presentation by watching the machines and paying very little attention to the narrator/robot lol 😂. At least they started calling them shovels as opposed to excavators in the beginning.

6:01 1.37mph is absolutely slow as a snail 🐌

I used to occasionally run our 335 Cat on our farm, and thought it was huge. Thanks for posting.

Excavator yang besar 👍

Крутая техника! 👍👍👍👍👍

Wow

Now build a d12 dozer 🤷‍♂️

Not an excavator, it’s a shovel.

And I complain about having to fill the tank in my F-350. Sheesh! Can't imagine what it cost to run one of these things for a day.

It's operating weigh is 1000 metric tonnes/1102 short tons

Big machine!

Liebherr r9800 would of been cool to see next to it

Them there are not excavators them there are shovels not a robotic arm an excavator works just like a human are not backwards but cool in fact you can put a thumb on an excavator and work it the same as a hand can't put a thumb on a shovel

I still can’t figure out how the Tri Power works🤔. 🤓

*the Bucyrus Erie

Shovel. Front bucket shovel.

6090.......nice

German power 😎✌🏻

"DEVASTATOR!"

What would be the price of this monster?🤔

Thought the 870g I run was big!

So I imagine it has a crapper as well?

I need one in my sand box.🚜

Thing could've dug the Panama canal in a weekend

What country is the cat version now made.

i hope that thing not a decepticon

*here's robot voice* *immediately closes video*

Im more impressed by the Hitachi ex8000

I is thought Hitachi EX-8000 was the Largest

but will it fit in my garage?

A Cat machine with a Cummins motors???

I highly doubt there are 2 Cummins engines powering a 6090

This is a AI created video….

6090 fs weighs 1000 tonnes

XCMG, Komatsu, Hitachi and Liebherr all make bigger machines. I think this is a North American video, for North Americans. (They don’t travel much).

Not the biggest
