Which risk increases when excessive cyclic load occurs in a gantry crane controlled by a PLC?

💡 Explanation

Excessive cyclic load causes material fatigue because metal components experience repeated stress cycles, leading to micro-cracks, resulting in crack propagation via fatigue mechanism. Therefore, hoist cable failure increases, rather than electronic failures in the PLC due its control algorithms.
