Root cause analysis and evaluation of corrective actions for discharge boom suspension failure in bucket wheel excavator
The article analyzes the failure of a bucket wheel excavator's discharge boom suspension. The failure caused significant operational disruption and financial losses. The study includes metallographic tests and FEM analysis of the damaged axle, revealing a fatigue fracture due to inappropriate material microstructure and a structural notch. The fracture led to the boom falling, damaging the excavator and conveyor. Corrective actions involved redesigning the axle and using suitable materials, verified through extensive testing, to enhance durability and prevent future failures, ensuring safer operation.
