A Bucket-Wheel Excavator on Earth
Credit: ThyssenKrupp Technologies, SwapMeetDave

Explanation: Please wait while one of the largest mobile machines in the world crosses the road. The machine pictured above is a bucket-wheel excavator used in modern surface mining. Machines like this have given humanity the ability to mine minerals and change the face of planet Earth in new and dramatic ways. Some open pit mines, for example, are visible from orbit. The largest excavators are over 200 meters long and 100 meters high, now dwarfing the huge NASA Crawler that transports space shuttles to the launch pads. Bucket-wheel excavators can dig a hole the length of a football field to over 25 meters deep in a single day. They may take a while to cross a road, though, with a top speed under one kilometer per hour.

That is an awesome machine!

We have several of those monsters in Fort MacMurray mining Bitumen for syncrude production.

Yes they are really something to behold.

Yes, don't you see the smaller yellow bulldozer on the left?

Actually I believe they are diesel electric.

Those who like big machinery might like to browse this ThyssenKrupp website: ThyssenKrupp Robins Products.

I don't know the particulars of the machine illustrated, but many large shovels, draglines, and excavators are strictly electrically powered with some of the world's biggest extension cords. It takes a bulldozer to drag the cord around as the machine is moved.

Here's some info on a machine that has worked the coal fields near where I grew up for a lot of years: Silver Spade
