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.
