A few months ago, I asked people what the machine was in a picture I found on the Net. Many people commented and identified it as an earth-mover of some kind.
However, I got an email from Ian recently that included a somewhat cheesy Power Point Show which included the pictures at right (click for 600-pixel versions) and this text:
This is the largest earth mover in the world built by the German company, Krupp, and seen here crossing a federal highway in Germany en route to its destination (an open-pit coal mine). It is cheaper to move the thing like this, than to construct or reassemble onsite.
The mover stands 311 feet tall and 705 feet long.
It weighs over 45,500 tons
Cost $100 million to build
Took 5 years to design and manufacture
5 years to assemble
Requires 5 people to operate it
The Bucket Wheel is over 70 feet in diameter with 20 buckets, each of which can hold over 530 cubic feet of material.
A 6-foot man can stand up inside one of the buckets.
It moves on 12 crawlers (each is 12 feet wide, 8’ high and 46 feet long)
There are 8 crawlers in front and 4 in back.
It has a maximum speed of 1 mile in 3 hours (1/3 mile/hour)
It can remove over 76,455 cubic meters each day. (100,000 large dump trucks at 40yds. each)
One hundred thousand dump trucks per day? Wow. I can’t vouch for any of the validity here, but it’s a big machine no matter what figures you slap on it.
A while back, we posted about a picture of a big machine I had stumbled across. Sometime after that, it was identified as a mining machine over in Europe, complete with many pictures. Last night, I was watching Modern Marvels on The History Channel (great, great show), and the topic…
Found on the Net with no explanation. Can someone please tell me what this machine is? I'm dying to know.
I was going to say I could probably take control of my city with this thing. Then I realized that it only traveled 1/3mph. I would roll over in my sleep faster then that. It's an awesome machine though. I can't imagine how many man hours it took to assemble that bad boy. I wonder how many battle ships would need to be melted down to match the amount of metal required to build that thing.
I say we arm one, put troops on it, and drive it through Baghdad.
dz; Lovely idea, then crafty Iraqi's can just snipe the silly Americans off of it.
I say we arm one, put troops on it, and drive through droptone's front yard.
I should have seen your inital post earlier, because those machines (there's about a dozen of them) work only a few kilometers away from me.
I haven't browsed through all the comments, so maybe this is redundant information:
In Germany, there is an are in the triangle between the city of Aachen in the West (where I live) close to the Dutch and Belgian border, the city of D�sseldorf (in the North) and the city of Cologne (in the South), where the "brown coal" resides very low beneath the surface. So you don't need to dig shafts and do traditional mining, but you can actually scrape away the earth to get to the coal stratas.
From an environmental point of view this is of course a desaster - these machines dig huge - and I mean HUGE - holes into the earth: see http://asterweb.jpl.nasa.gov/gallery/images/mines-fix.jpg (I live at the lower left corner of this image). however it still is way cheaper than shaft digging.
There's 4-5 coal burning power plants next to the scraping sites which immediately consume the coal to produce energy for the German heavy-industry area.
The images shown in your post display a transport of one of the diggers from one site to the other - a very slow process a few years ago which got a lot of media attention because rivers had to be moved and roads blocked.
Very soon, one of the machines will dig away a whole highway - for years to come we have to drive a rather long deviation when we want to go from Aachen to D�sseldorf. Once the machine has gone past this point, the mining comporation has to rebuild the highway.
Socially it's a challange too, because whole villages get destroyed and rebuild a few kilometers away.
The whole thing is way to crazy to understand why anybody came up with it in the first place.
P.S. The satellite image is large: make sure it's displayed completely - you should see 3 huge scraping sites.
That image is nuts. When you can see something like that from space, it pretty much means you've made Mother Earth your b**ch.
Maybe worth mentioning, the triangle covering all three sites is about 50x50x20 km in width.
I am coming to Germany in August and want to see these things. Can the mines be visited somewhat close? Exactly where are the mines? I see on my map Dusseldorf, Aachen and Koln - is there a smaller town that they are very near? We are flying in to Hannover and that looks pretty close.
Germany is not THAT small - from here to Hannover is still a 3,5 hour ride. You might want to include a visit to Cologne (which is a nice city in its own right and certainly worth a visit) and from there it's like a 30-45 minute drive.
I don't know if there are official tours - they do prearranged tours for sure. I can see if I find some links - just drop me an email at pmk at naklar dot de and I'll send you some web-ressources.
Depending on your budget you can go to one of the smaller sport airports. It should be easy to find a pilot willing to take you on a tour with a Cessna and they can fly pretty low over those "wholes". I can only guess the tariff but I assume something between 100-200 EUR for a one hour flight.
Here's a link to the same area on Google Maps. I arranged the map so that my hometown is exactly in the lower left corner (I live next to the second "o" in "Google"). On the upper right corner you see the port of Duesseldorf at the river Rhine.
You may notice the thin line of the highway (the "Autobahn"), which diagonally crosses the image from lower left to upper right. At the topmost scraping site, the Autobahn is only about 20 meters away from the rim - and that's actually the place where the Autobahn will be disrupted soon because the "mining" goes farther to the west.
But what is the story behind the bulldozer stuck upside down at the top of the machine in the last picture? Is it real? It does look like it, so how on earth did it get there?!!!
The bulldozer was caught by one of the buckets and they used a crane to remove it from the top of the unit. It is a D-8 caterpillar and looked to be nearly new. I got an e-mail that showed about 6 more pictures of the scene. Neat, but I hope that nobody got hurt. (somebody probably got yelled at though!)
That is a very large amount of coal to move. My questions to you are: 1.Who owns the land that is to be mined? 2.Does the Government purchase it off the owners or the Energy Companies who run the Power Stations,or do they just pay for relocation?
I don't think the math is right in what the thing can excavate.
76,455 cubic meters of earth is equal to 100,000 cubic yards. At 40 cy per truck that's "only" 2,500 trucks. That's still a lot because the 40 cy trucks are the big off-road haulers.
I was stationed in Shonigen Germany (pronounced "shernigen") back in the 80's We could see part of the coal mine from the main route between Shonigen and BaunSchwiege. Braun Shcwiege is a "college town" on what was then the East / West German Boarder. You could see one of the earthmovers along that route - but that was 20+ years ago, so I don't know if that would still be the case today... I am sure the mine is still there. Back then it was "billed" as the largest open pit mining operation in the world.
Thats big
Oh, Steve, this is maybe a bit late for the answers, but here you go:
Who owns the land? The utility company by the name of "Rheinbraun" owns all the land. If a landowner is not willing to sell, he gets dispossessed (and reimbursed) by a court - the land is then sold to Rheinbraun. Actually as a land owner you stand NO chance not to sell...
Can you design your own home? Yes, of course. You get money based on what your previous land and home was worth, you get cheap loans and you get special deals. With that, you can build whatever you want.
Do these machines have an appropriately aggressive name?
I'd simply call it "Earthmover" or "Deathmachine"
