In this paper, full-scale airframe static test of 4-seater canard airplane(the Firefly) was explained. From the results of the structural analysis, 5 design limit loads test conditions and 11 design ultimate loads test conditions were selected. Test loads analysis was performed and test fixtures and load control system(LCS) were prepared to realize the test loads. To protect the test article during the test, the overload protection system was prepared. Strain and deflection values were acquired through the data acquisition system(DAS) to verify the structural analysis results.

In this study we analyze operation principle of wedge type rail clamp using in the harbor and when wind force applies to container crane, we calculate deformation in each part of rail clamp. As a result of calculation, we will design rail clamp supporter that forbid overload to be applied at rail clamp according to adjust climbing wedge distance of roller. It would be adapted various container capacity and wind velocity.
