The fracture failure causes of an escalator driving chain were analyzed by the optical microscope and scanning electron microscope analysis. The surface decarbonization of the driving chain plate can be observed. From the macro and micro analysis of the fracture surface, the fracture of the driving chain is caused by fatigue.
