While the Large Hadron Collider is the largest underground machine, the world’s second largest machine is chewing up surface above the ground. The Bagger 293 is a brute built for titans. Built in Germany in 1995, the giant bucket wheel excavator stands 315 feet tall and 740 feet long, and weighs in at 31 million pounds. This multi-ton Tessie uses five operators to push her along, and can move 8.5 million cubic feet of earth per day.
