Some manhole cover accidents have been listed. The direct cause and root cause of manhole cover accident have been analyzed. Anti-rolling fatigue testing for manhole covers has been put forward and studied. Test parameters and decision methods have been determined.An equipment for manhole covers anti-rolling fatigue testing, which including equipment structure, equipment parameters, manhole cover installation structure and equipment operation, has been studied and designed.
