| Abstract: | Aiming at the potential safety hazards from the high accident rate of old cranes,as well as the difference between design service life and actual service life of metal structures,acoustic emission technique,stress test,online monitoring and Miner theory are adopted for safety assessment and service life prediction so as to provide advice of timely maintenance,degrading use and discard disposal for the unreliable equipment.It is forbidden to use the crane with overload or the crane out of its service life. |
