Bagger 288
The Excavatrice Bagger 288 is the largest crawler-mounted vehicle of the world. It is a bucket wheel general purpose excavator, built to help with the extraction of the coal on the surface. Manufactured in 1978 by Krupp for the mining company RWE Rheinbraun, it weighs: 13500 tons. Bagger means general purpose excavator in German.
It has as a function to clear the ground cover in order to release the coal veins. It is 240 meters long for 96 meters in height and can clear until 240 000 tons per day. It requires a power supply of 16,5 Mégawatt S. the central body of the general purpose excavator can move up to 10 meters per minute, that is to say 600 meters per hour. It rests on three series of four caterpillars, each one measuring 3,8 meters of width. The radius of curvature of the unit is approximately 100 meters. Five people are enough to make function the general purpose excavator.
The bucket wheel itself measures 21,6 meters in diameter and contains 18 cups or buckets, of an individual capacity of 6,6 tons ground.
In 2000, it finished clearing the totality of the layer of Hambach. In February 2001, it was moved to the mine of Garzweiler, distant of 16 kilometers. The voyage was done through a Autoroute, a Rivière (the Erft), and a line of Railroad; the general purpose excavator traversed 22 kilometers in order to limit the changes of altitude, at a cost of 15 million marks.
21 identical specimens were manufactured by Krupp.
