The bucket wheel excavator was invented in the mid-20th century to improve the efficiency of mining operations, particularly for coal and other minerals. Its design was inspired by earlier technologies, such as dredges used for digging in rivers. The machine features a rotating wheel with buckets that scoop up material as it turns, allowing for continuous excavation and transportation. This innovation greatly enhanced productivity and reduced labor costs in open-pit mining.
