he world’s largest electric coal shovel stands 16 stories high (160 feet) and weighs 11 million pounds. From 1963 until 1974, this one-of-a kind, black and orange behemoth worked seven days a week, 24 hours a day moving dirt and rocks aside so coal could be mined. When it came time to retire Big Brutus, operators backed it out of the coal pits, parked it and removed its engines. Today, the giant shovel is the centerpiece of a museum dedicated to miners and mining history.
