The bucketwheel excavators (BWEs) often used in surface mining of soft coal deposits are gigantic machines. With great size comes great punishment. BWEs must absorb a tremendous amount of impact shock and vibration during overburden stripping operations. Although they’re built to be extremely robust machines, the constant pounding takes its toll and repairs or replacement of parts inevitably becomes necessary. Again, along with great size comes great difficulty in planning, executing and safely, cost-effectively completing procedures on one or more of a BWE’s jumbo-sized components.
