Structural Strength Analysis of Ship-to-Shore Crane

It is necessary to analyze the strength of STS crane with static load for assessing the safety of the STS crane. A case study of a STS crane with 28 ton capacity and 18 years of working time has been conducted. A testing system with signal sensing, signal conditioning, signal acquiring and signal analyzing has been established. After the field test, all the stresses of the test positions have been calculated and the strength of STS crane with static load is in the allowable range. As a result of this study, a systematic approach to analyze the strength of STS crane with static load is proposed.
