Bagger 288 Excavator
Bagger 288 is the largest excavator
launched by the German Company Krupp in 1978 with a length of 721 feet, height
of 315 feet, diameter of 22 meters, and drive as high as 8 floors. In addition,
this mining vehicle is also the heaviest vehicle in the world with a weight of
13,500 tons which has replaced the previous largest vehicle, Big Muskie. This
dredging machine in one day is able to move 8.5 million cubic meters of land.
This excavator has the biggest bucket wheel in the world and has an economical
and very efficient engine.
With a heavy vehicle
weight, the removal of Bagger 288 must be done by the workers with extreme care
so that the road is not destroyed by covering the road using thick sand.
Despite its heavy weight, this vehicle does not require many workers to operate
it but only consists of 3-4 people. Also note
that the surface area consists of 12 crawlers with 8 on the front and 4 on the
back, so as not to leave too deep traces when passing through gravel, soil and
even grass.
In 2001 the excavator was
used at the Garzweiler open lignite mine, which had previously operated at the
Hambach mine to excavate coal. The excellence of this excavator is proven when
moving the mining vehicle from Hambach to Garzweiler for a 14-mile trip and
spent about 3 weeks with a max speed of 10m / min and a min radius of 100m.
During the transfer process, a crew of 70 was needed and cost around $ 10
million.
This excavator is driven by an 840 kW
four-wheel motor with an aggregate drive power of 3,360 kW or equivalent to > 30 compact cars. When
designing and constructing this mining vehicle concept, a significant amount of
time is needed, which is 5 years, plus 5 more years to assemble it, which costs
$ 100 million. In addition, this largest land vehicle has a thick cable capable
of producing 30,000 volts of power with a cable > 120 km.
