” Bagger 288“, built in 1978, is the world’s largest “digger”, designed for open mining trenching. More pictures after the jump.
It was built for the job of removing overburden prior to coalmining in Hambach, Germany. It can excavate 240,000 tons daily—the equivalent of a football field dug to 30 meters (98 ft) deep. The excavator is approximately 240 m long and 96 m high. To run, the Bagger requires 16.56 megawatts (22,207.33 HP) of externally-supplied electricity, it can travel 2-10 m per minute (0.6 km/h). The chassis of the main section is 46 metres wide and sits on 3 rows of 4 caterpillar track assemblies, each 3.8 m wide. It has a minimum turning radius of approximately 100 metres
