Bucket wheel excavators are another design of continuously operating excavators. The buckets are mounted at the rim of a revolving drum. As the drum rotates, each bucket in turn scoops up material. The bucket wheel is located at the end of an arm, which can pivot upwards. During the revolution of the drum, the contents of each bucket are falling inside the drum and through a system of deflectors on a conveyor belt. The conveyor belt transports the excavated material along the bucket wheel arm to the central pivot of the excavator. There it falls on to another conveyor belt, which transports the material to a loading facility for e.g hopper cars.
A bucket wheel excavator consists of the lower works with the crawlers and the upper works with the bucket wheel arm, the counterbalancing arm and the mechanism for raising and lowering the bucket wheel arm. The upper works can pivot through 360 degrees around the vertical central pivot axis.
Initially bucket wheel excavators suffered from rather low forces at the cutting edges of the bucket wheel, limiting them to removal of soft materials like lignite, sand or gravel.This problem partially overcome, allowing removal of hardened or even frozen sediments too, modern bucket wheel excavators are making even inroads against the use of discontinuously operating excavators. In comparison to bucket chain excavators bucket wheel excavators are more versatile, allowing selective harvesting of e.g. lignite in geologically disturbed strata. Because of that they are gradually replacing bucket chain excavators.
Bucket wheel excavators are also widely used at storage and mixing sites for ores and black coal.
The first large bucket wheel excavators were introduced into German and Polish lignite opencast mining during the 1930ies. They continued to be built after WW II in both parts of Germany as well as Czchechoslovakia and the Soviet Union. They are ranging in size between less than 100 t to more than 70,000 t gross weight.
Over the years design of bucket wheel excavators changed considerably. The SRs 1200 represents a medium size design of the 1950ies. According to the nomenclature used with the East German lignite mining industry the capital S stands for bucket wheel excavator, R for crawlers and the minor s for the capability for swiveling the upper works trough 360 degrees. 1200 refers to the approximate service weight in metric tons.
The model was created as an industry asset capable of loading either spoil or lignite into enabled traincars like kuid:142675:1258 and kuid2:211961:15000:1 or others. The horizontal angles of the loading arm and the upperworks as well as the vertical angle of the bucket wheel arm are adjustable in surveyor.
