Abstract—The winch is the equipment used in many different fields of industry. The drum is an important part of the winch. In the previous study, we designed one personal rescue winch for high-rise building rescue. Its key requirement is to be small and light enough to suit users. Many design factors of drums have not been fully investigated. In particular, the influence and importance of each factor on the drum weight need to be fully evaluated. This article establishes the process and studies the main factors affecting the drum weight of the rescue winch. The main influencing factors are materials and structural parts. This study uses numerical methods with the support of Inventor software. The correctness of the model is verified through the analytical formula. The research results showed that the material is the decisive factor in the drum weight of the winch. For the structure, the drum thickness is the decisive factor. When local stress effects are taken into account, the drum mass can be increased. The research results help us to choose the appropriate method to optimize the drum of the rescue winch in specific conditions.
