  • Bucket-wheel excavator wiki | TheReaderWiki

    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

    In this respect, equipment revitalization and modernization is a key issue. This paper deals with the analysis of the time response of the boom structure of a bucket wheel excavator (BWE) during operation. For this, we propose a virtual model of the boom, on which a variable-in-time force generated by the bucket wheel acts.
