The excavator was 288 for the job to remove overburden from the mining in Hambach opencast (strip mine Hambach), built in Germany. It can excavate 240,000 tons of coal or 240,000 cubic meters of waste per day - equivalent to a football field dug the (football) to 30 m (98 ft) deep. The coal produced in one day fills 2400 coal wagons. The excavator is up to 220 m (721 ft) long and about 96 m (315 ft) high. The excavator's operation requires 16.56 megawatts of externally supplied electricity. It can travel about 2 to 10 m (6.6 ft to 33) per minute (0.1 to 0.6 hours km). The chassis of the main part is 46 m (151 ft) wide and sits on 3 rows of 4 caterpillar chain assemblies, each 3.8 m (12 ft) wide. The large surface of the rails is the ground pressure of the backhoe 288 is very small (17.1 or 24.8 psi N/cm2) allowing the dredging of gravel, dirt and even grass, to travel without a clear track. It has to climb a minimum turning radius of about 100 meters and a maximum gradient of 1:18.
The excavations head itself is 21.6 m in diameter and has 18 buckets each holding 6.6 cubic meters (7.9 yd ³) of overburden.
In February 2001, the excavator completely exposed the coal source at Hambach mine and was no longer needed there. In three weeks it's from a 22-kilometer (14 mile) trip to the Garzweiler, traveling on Highway 61, the Erft, a railway line and several roads. The move will cost nearly 15 million German marks and requires a team of seventy workers. Rivers were, by flow through large steel pipes for the water and passed through a smooth surface above the pipes with stones and gravel. Special grass was sown, its smooth passage over valuable land. Move excavator 288 in one piece was more economical than the dismantling of the excavator and moving it piece by piece.
Excavator 288 is one of a group of similar size and built vehicles such as Excavator 281 (built in 1958), 285 Excavator (1975), 287 Excavator (1976), 293 Excavator (1995), etc.
