“The world’s biggest saw helps workers in Kazakhstan plough through hillsides by digging out 4,500 tonnes of coal an hour. Towering in at just over 145 feet and weighing a staggering 45,000 tons, the massive machine obliterates anything in its path. The saw has jagged buckets attached to the rotating blade – which works in a similar fashion to a chain saw. The buckets dig deep into the coal seam and break off mammoth chunks – before it travels around a conveyor belt and straight into containers positioned on waiting trains. The mammoth excavator needs a total of 27 people to operate it at any one time. Slava Stepanov, who took the above photo, explained that whoever operating it from the armchair at its top is the envy of all workers.”Source
