Wind tunnel test of a 7 500t floating crane was conducted with a 1∶200 scaling model. The balance force was measured to discuss structure response against different working conditions and wind inlet angle. 78 working conditions were considered according to 3 typical luffing angles, 2 possible wind field landscapes and 13 wind inlet angles. The test results were concluded to non-dimensional results. The results indicate that: 1) wind load along isometric direction (135°wind angle) reaches the highest point; 2) The smaller the luffing angle, the larger the wind load; 3) The wind field landscape plays a small role in wind response.
