Worlds Biggest Saw
This is the world’s biggest saw – that can cut through mountains like a hot knife through butter. The monster machine is used to cut gaping holes through huge coal mountains in Kazakhstan – and can obliterate anything in its path. Towering in at just over 145 feet and weighing a staggering 45,000 tons, the massive machine can scoop 4,500 tons of coal per hour. And it takes a team of 27 miners just to operate the bucket wheel excavator at any one time.
