Bucket-wheel excavators
Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining. The primary function of a BWE is to act as a continuous digging machine in large-scale open pit mining operations. These BWEs were photographed at the Garzweiler surface mine in Germany.Photograph: Raimond Spekking
