Bucket and operators cab from mining equipment called The Silver Spade on Stumptown Road west of New Athens , Ohio

Although it ’ s not operational anymore , the Silver Spade ’ s track record earns a place on our list of mega earthmovers . Weighing in at 16-million pounds , the Silver Spade is taller than a 12-story building and the last giant stripping shovel to operate in the world . This beast of a machine lasted over 40 years of hard labor and moved over 600 million cubic-yards of rock .
