In this paper, we carried out a stress analysis in optimizing a carrier of the slewing reducer of tower cranes. Through the structural analysis, we verified the stress changes of the carrier and performed a strength evaluation on it. In addition, we conducted an optimization of the carrier shape in order to meet the required safety factor. Finally, we suggested a solution to avoiding stress concentration due to the shape change of the carrier.
