Biggest excavator in the world

Biggest excavator 

In the construction work mostly excavator are used for cutting and filling in the road construction and building construction in hill areas . different types of excavator are used in this work according to trhe nature of work.

When its construction was completed in 1978, the Bagger 288, the world's largest land the Space Shuttle and Apollo Saturn V vehicle as the launch vehicle (Marion Power Shovel Company of the excavation by the manufacturer built) take Used to go superseded NASA's Crawler-Transporter, for bucket wheel excavators are powered by an external power source 13,500 tons since. [1] NASA's Crawler-Transporter, still lives in the world is self-propelled land vehicle.

The Bagger 288 Hambach stripmine coal mining in Germany before the work was made for removing the overburden. A football field (Soccer) equal to 30 meters deep (98 feet) digging - it 240,000 tons of coal or [2] daily 240,000 cubic meters of overburden can dig. Coal produced in one day fills 2400 coal wagon. Digging high long 220 meters (721 feet) and approximately 96 meters (315 feet) across. The operation of Bagger 16.56 megawatts of externally supplied power is required. [3] This per minute (0.1 to 0.6 km / H) 2 to 10 m (6.6 to 32.8 feet) can travel. The main part of the chassis wide 46 meters (151 feet) and 3.8 meters wide each (12 feet), 4 Caterpillar track assembly sits on 3 rows. Bagger 288 large area of ​​the tracks that very little ground pressure (1.71 bar or 24.8 psi) means, it's a remarkable track excavator without leaving gravel, earth and even allowing them to travel on the grass . This is a minimum turning radius of approximately 100 meters, and the maximum gradient of 1:18 can climb.

Excavating head itself in diameter, 21.6 meters (70.9 feet) and 6.6 cubic meters of overburden (8.6 yd³) holding 18 buckets.

By February 2001, works entirely through Tagebau Hambach mine coal was exposed and there was not. Three weeks from the Autobahn 61, the river Erft, a railroad, and travel across several streets, Tagebau Garzweiler a 22 km (14 miles) made the trip. The move will cost about 15 million German marks and a team of seven workers. By the rivers of water to flow to large steel pipe with stones and gravel by providing a smoother surface than they were crossing. Special grass valuable area was seeded to smooth its passage. Bagger 288 excavator to remove in one piece and the piece of disassembling it was more economical to move the pieces.
