Conclusions and future work To increase the reliability of overhead cranes a Structural Health Monitoring system is presented based on load monitoring to calculate the remaining life of the crane steel structure. The monitoring system is using a combination of SCADA data and optical fibre strain sensors. These measurements are used for load monitoring and event detection. It is illustrated that the measurements can be used to calculate the dynamic coefficients as well as horizontal bending. Future work will focus on further industrialization of the system and fine tuning of the elaborate user interface for maintenance crews and crane operators.
