Abstract

In this paper, a shipbuilding gantry crane serviced for up to 18 years is studied; the strain-measuring method is used for testing and analyzing the response of the structure and the load about the main force component-cylindrical structural. By arranging the measuring point 90 ø to each other on the cylindrical section of the maximum bending moment, the rule of stress conditions of cylinder is established. The results showed that: when the crane lifting, the same side in the cylinder has the maximum compressive stress, which mapped side has the maximum tensile stress, the stress of both sides of the vertical part is minimum; When the rotating mechanism run a week, the same section of the cylinder will show a cyclical linear change with the rotation angle of the boom (jagged cyclical changes).
