  • Bucket-wheel excavator - Wikipedia

    A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining.. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a
