I visit the world's biggest hydraulic excavator and loader! a life long childhood dream rh400cat6090 

Biggest I ever saw here in England was the RH200 at Shotton. They also had lots of RH120 machines too. A group of us were in the RH200 while it was working filling dump trucks. The machine is bouncing all over the place. The Shotton site was located adjacent to the A1 trunk road in Northumberland. I shouldn't say this but explosives used for breaking the layers of bed rock to expose the coal had caused a problem near the A1 - a set of explosives had thrown rocks onto the grassy side embankment of that trunk road, fortunately none onto the tarmac. Bosses decided to push the face shovel through unbroken sandstone instead of using bang to break it! That machine, with its twin engines, simply ate through unbroken rock and is why we were bouncing a bit in the (large) cab. I'll never forget the memory of that massive face shovel eating through sandstone and every now and them a massive plate of the rock lifting away. The operator then gently placing it into waiting dump trucks. I know that extra work was said to be 'no good for the machine' as they dug into it. If you're interested, somewhere on RU-vid there's actual footage of the company making those face shovels in their factory. The initial pieces of metal, as you've shown in the video, looking nothing like the machine they would be welded up to be. I currently can't find it to link.

fantastic Allistair.....

Did a similar thing back in 1988 Allistair..Did the Greyhound Bus around Australia..Travelled over to Western Au to visit reli's..then travelled North to Nunutarra alighted the Bus and hitched hiked into Mount Newman, Via Wittenoom..met up with a fellow Englishman originally from Kent..called Derek Jones..who arranged a Site Visit..we were'nt allowed down in the Burrow pit but stood up above Mount Whaleback looking down into the BIG hole..Back then they were running Haulpaks (Dumptrucks) did'nt see any loading shovel's or Faceshovel's..A Great Day! also fed and watered in the workers mess..Derek arranged for me to travel up on the worlds largest privately owned Railway to Port Hedland..i stayed in contact with Derek up till last christmas when i assume the poor bloke passed away! In the Mines i'm assuming this is where you learned your Fantastic Welding Skill's..and possibly where you earn't the money to start your Business back in Ireland..Great Video!! guess we share the same passion..Cj Birmingham UK..ps i have a picture of stood alongside a Haulpak on my bedroom wall (24"x18")..taken on the 8/8/88..great video's and slide show

Absolutely brilliant video Thanks for your time and effort putting it together.

I never worked on the 2350 letourneau loader, but I spent a couple of weeks rehosing an 1850 Leturneau loader up in West Angelas mine about 200 klms north of Newman west Australia. That was back around 2003. It was in for a 60000 hour overhaul. If memory serves me right I think it was the third biggest wheeled loader in the world at that time. Good memories, and one of the best mine sites I worked in.

imagine that Terex boom breaking and Allister gets the repairjob.

Nice to see those two LeTourneau machines Allistair. The first of their models to come to Australia...

Rh400 can move almost 10k tonnes of earth/dirt per hour😳 which is wr for a vehicle this type and thank you for sharing this awesome video mate👍.

Love it, keen to see the milling machine move

Some.serious stuff there, must have been a kickboxing experience to just see them, well done to you Allister

In the "Go big or go home" department... you win, today.

Yes Jack King is right about the Shotton opencast operation, also the company used the excess spoil to create a vast monument known as Northumberlandia . Also over the years on site's in Northumberland big geordie a 1000 ton walking dragline also the ace of spades 4000 ton walking dragline , the ace of spades was bought by a company in America and shipped back to the US. Big Georgia was scrapped. Alistair keep these very interesting clips coming great variety

How do they put the tire chains on that wheel loader? They must way a ton on their own!

Awesome, another treasure trove of a video off yeah

I didn't think Ireland was big enough to need a loader that size.🤔

Totally insane, thanks for this video, myself always want to know more of it,

I wonder if this was recorded on WHS or a potato? its hard to tell

The cab on the loader is like a caricature, so tiny compared to the loader itself.

Just imagine doing an oil change of one of these beasts, you would need tank trucks for the old and the new oil... 😲 Great video! 👍👍👍

Love WA, you see all the fifo workers at the airport heading to the mines.

The wild thing about the 2350s is how little video there is of them on here. Maybe they didn't sell many of them?

and yes, a wide angle lens is very helpful with these Big Brutes.......is the Terex excavator a Diesel/ Electric drive/rotation or all Hydraulic????

👍

how many guys have to climb 2 stories of stair cases to get to the seat of their work rig

do you do any machining

oh yeah that's a pretty big dump truck. tires taller than a man

you did not mention the fantastic arc gouging......that is pure sex......

a few questions: how are the engines in these monsters started? i.e. electric, air, pony motor why does the loading shovel have tire chains?

Did you meet Kurtis from cee when you were out there. Lol.

all kids toys. get some r.c hydraulic ones mate. boring this show

Allistair....such a great video.....best wishes from over in the US, Paulie......

Used to regularly see the tyres go by me from the port, one per abnormal load, on the way up to the PMC operation. When you drive past PMC and see them in the pit they do not look big, till you realise that those tiny little machines crawling up the incline are massively larger than the dinky toy Hilus bakkies, and you realise that the red flag on the tall pole are really there so the operator has a chance to see that he is only a tiny bit away from making a Hilux flattie, without even noticing it. Same for the D6 dozers at the brickworks, which also had armoured cabs, more for the errant rocks than for the shooting, though they did get a fair number that came in with AK rounds in the radiators, and skid marks on the housings, though any that went into the tyres would not even be noticed.

Thank you Allistaire. Fort McMurry in Alberta has some good sized machines.😂

great footage lad, I had the pleasure of operating machines for a sub-contract crushing company at the Fmg site from 09-10 I must see what footage I have Was a big change from working for roadbridge where a ec700 volvo was considered a huge machine at the time

You having spent time in Australia know that when it comes to big Australia generally has it. I watch stuff from US. Who according to them always has the biggest and the best. Like their trucks. Nothing comes close to a six trailer road train coming out of the mines. Trucks, trains and earth moving. Amazing scale out here.

Awesome footage of the most colossal machines. That must have been some experience. 👍🏽 good stuff

I'm 66 and remember going to a open cast mine on a school trip , must have been localish and seeing a hole where the digger was , we were told could be as old as roman times , why we went there I have no idea LOL .

Just the cover plate on the final drive housing would hand you your ass on the RH400.

Quality ... Thank You Kindly for sharing peace

You will need to come back to check up on the Komatsu Wa8000 round 800 tons I think 3 of them working in the Kalgoorlie super pit That Terex digger was originally designed by O&K in Dortmund worth a look up in Wikipedia I worked on the RH 200 in 1992 and at that time they had a built in computer capable of remote operation they were a well built machine some of them would have worked efficiently up to close on 100,000 Hrs which in mining would be approx 15 years

I might have seen thoes l2350's on the production line. I went to College "across the street" from the plant and got a tour. I remember them saying they were headed to Auz. Seeing the engine and machined balljoints for that thing disassembled was something I will never forget. That was a long time ago but still vivid in my memory.

Thanks for clarifying why the dump beds on the haul truck looked so small relative to the size of the truck and tires.

Beast of machines and then there's the monster walking draglines I remember seeing one of the Corby draglines being walked across country straight through fields hedges and no doubt crossing a few roads 1670 tons think it took well over a year

Hang On You could, invade a whole country with a machine like that ,Ukraine war needs it for defence .

Beefy equipment for sure, thanks.

MM77 Approved 👍🏼👍🏼……………………………………………….WOW!!

Absolutely brilliant video

Very cool. That had to have been fun!

the dam hub of the tire is as tall as a man

Please,please come to America and see a Saturn V rocket ,the most powerful machine ever built!!Comparatively those machines are toys! At 7 million pounds it would crush those machines like a house of cards!

Why do the dump trucks cargo containers appear to be tiny when compared to the chassis and cab. It does not look to be capable of carrying a high capacity load?

I wouldn't like the job of changing tracks or tyres on them! Very interesting stuff young man!

👍

Good to see your collection... good to see your face! Thanks for posting your old videos, more would be welcome. There may be stabilization programs you can use to process them. The still pictures at the end are easier to examine closely.

Astounding!!! You must have been smiling for days! Thanks for sharing 🇨🇦

I think that dumper (or very similar) was featured in a Jackie Chan movie in 1997 "Mr. Nice Guy". I think it was set in Australia, and wouldn't you know it, looks like that dump truck on the cover when i checked IMDB. I must say that excavator looks as if it could budge a mountain a few inches!

I remember back in the late 70's, seeing five or six big CAT dumpers along the M1 England, they took up the hard shoulder and most the first lane. I was in my Dads DAF 2300 passenger seat and looking up at the cab, tipper just cleared the bridges. Not sure what number they had but they were big. Great to see them from the past. Cheers

Remember a tale from my BIL about when a tropical cyclone hit, and was busy undermining a major road, and they needed to move fill in. Only the one quarry operator was there doing it, running his D6, and he only had 2 speeds when operating, flat out forward, or flat out reverse, and regulated speed with the blade, moving a hillside down into the river to stop the erosion from undercutting the bridge and road. Smaller dozers to sort of handle the side spills, but he was busy flat out in the rain, tearing away at a hillside and moving it towards the river. Dozer had a good work out, and the hill was a lot smaller when the water finally subsided.

Excellent to see videos from you I'm trying to come over via cairnryan to visit the area, I was always working about NI but never had time to explore, such a nice place with really friendly people I always found

Because I work in engineering I try to imagine the fabricators ,machine tools and assembly facilities to make those machines . Mind boggling scale .

All I can say is awesome what a thrill to get to see these machines in person. And to get to see them all on the same trip . 🤔👍😎

Awesome brotha keep it coming!!!

as always brilliant

can u make a log in it ?

Interesting Video.

WOW..........
