Bagger 293 is the world's largest bucket-wheel excavator built in Germany in 1995.
It is about 315 foot tall , 750 foot long and weighing over 31 million pounds.
It requires a crew of five to operate and can move over 8.5 million cubic feet of earth per day , to put that in perspective , that is the equivalent of digging a hole of the length of of a football field and over 80 foot deep in a day.
Its first name was MAN/TAKRAF RB293 given by the manufacturers they built it.
For the excavation the Bagger 293 uses a large 70 foot rotating wheel at the end of a long arm.
The wheel has a series of buckets attached , and as the wheel rotates the buckets pick up the earth and dump it onto a conveyor belt.
The conveyor belt will transport the earth to other vehicles for removal to the dumping site.
