The excavator

The first excavators came in the beginning of the 1900s and changed road and building construction completely. The early cable excavator was a mechanical masterpiece which was controlled with levers that made cables attached to the bucket interact.

In Sweden there was a resistance to mechanization. In the beginning of the 1930s road works would be carried out by hand to provide work for more people during the depression. In 1952 George J. Bataille came up with the idea of using hydraulics on machines. They then became lighter, easier to drive and could carry out precise maneuvers in a manner not previously possible.
The world´s biggest excavator is called Bagger 288. It is 100 metres high, 220 metres wide and has a digging head that is 21.6 metres in diameter.
