Ultimate Earth Mover

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.
Specifications:
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)
