World's Biggest Machine?A friend of ours recently sent us this photo of what is said to be the biggest earthmover in the world. Built by the German company, Krupp, it's shown here crossing a highway enroute to its work site at an open pit mine.
The giant machine is 311 ft. tall, 705 ft. long and weighs 45,500 tons. It cost $100 million to build and took 5 years to design and manufacture. The bucket-type digging wheel is over 70 ft. in dia. and fitted with 20 buckets, each of which holds more than 530 cu. ft. of material. It moves on 12 crawler tracks, which each measure 12 ft. wide and 46 ft. long. Each day it digs enough dirt to fill 100,000 large dump trucks with 40 yards of dirt apiece. It takes 5 men to run it.
