Electrochemical Fatigue Sensor
Frequent fatigue failure of heavy mining equipment is a well-documented issue. One component that often sustains this type of damage is the cable shovel boom. A history of chronic fatigue damage has been observed emanating from the bottom flange and propagating into the inner web plate.
Strain gaging and finite element has shown discreet areas where cracking occurs in these structures. Crack growth monitoring is the most effective way of avoiding costly failures and instead implementing repairs as necessary.
Through using the Electrochemical Fatigue Sensor (EFS) System, crack growth and its associated rate can be determined long before it is evident during a routing inspection. Using MFS’ FatigueWatch and our Long Term Electrolyte materials, this monitoring will be key in avoiding these costly and sometimes fatal failures.
