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.
