Abstract
The invention relates to an extracted-quantity control system for a bucket wheel excavator (6), in which the slewing speed of the bucket wheel boom (7) and/or its vertical position is controlled while taking into account the bucket-wheel drive current as well as the weight and volume of the extracted material, the extracted volume of solid material cut by the bucket wheel being used as a further control variable. <IMAGE>
