The safety performance of bridge type grab ship unloaders are the main factors in the normal operation of a bulk cargo wharf. This article made a research of the stress test technology on the use of safety assessment on the structure of the bridge type grab ship unloader, through the dynamic stress test of ship unloader key parts of the structure under the use of the condition, analysis bridge type grab ship unloader safety performance is at ordinary times and maintenance and inspection needs to focus on the dangerous site. Stress test shows that the Maximum compressive stress is Point 7, its maximum dynamic compressive stress is 82.5 MPa; while the maximum tensile stress occurs at point 11, its maximum dynamic tensile stress of 72.5 MPa. After 17 years used, The force main parts (except former trolleys) of the ship unloader are basically the same as its design value.
