The high performance shovel of the Liebherr R 9800 mining excavator has the phenomenal capacity of 45 cubic metres – the same volume as 400 conventional bathtubs. This monster can fully load a large dump truck in just three passes, but at 810 tonnes and 16.2 metres (17 yd. 2 ft.), it only takes 9th place among the largest excavators in the world.
In first place is a lignite excavator that was specially designed for RWE Power AG by MAN and Takraf. The RB293 bucket-wheel excavator operates at around 6,653 HP (6.745 PS), which corresponds to seven times the power of a Formula 1 racing car. It stands 96 metres (105 yd.) high – as tall as a skyscraper.
