The reliability of the lifting system has to be ensured so that heavy cargo is handled safely during loading and unloading. Therefore, the accelerated life test was performed on the lifting bow shackle, which is highly affected by the main failure mode, among the components of the lifting system. Besides, an efficient inspection method was suggested for the preventive maintenance of the bow shackles. The acceleration index and acceleration coefficient of the bow shackles were calculated by using the life data of them. The guaranteed life data of the bow shackle can be used to predict the useful life in industries related to lifting work.
