On this basis, it has been concluded that the bucket wheel excavator SRs 1200×24/4×0(400 kW)+VR safety criteria is the mechanism for the hoist of rotor's arrow failure modes, because in that case whole bucket wheel excavator failure would necessarily happen (excavator falling down on counterweight). Therefore, excavator units statistical safety analysis is accomplished preventively to obtain its effective maintenance management.展开更多
