dc.description.abstractThe bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of E) Non-destructive testing revealed a flaw in the butt welded Joint of the body and eye-plate of the bucket wheel tie-rod Its size exceeds the level allowed by current technical regulations An integrity assessment of the bucket wheel tie-rod has been carried out i e the remaining fatigue life has been determined based on the stress-state characteristics in the welded Joint and defined by experimental research in real working conditions The calculation results show that despite the excessive size of the internal flaw the welded Joint integrity is not compromised During periodical inspections of the welded joint in the past two years (BWE was put into operation in December 2007) changes that could compromise the structural integrity were not observed In this way by using a fail-safe philosophy design a considerable financial saving (ca 1 600 000 (sic)) was achieved while at the same time there was no threat to the worker s safety and life the safety of the machine and the production process in the open pit mineen
