Aiming at the problem of cabin module lifting in the outfitting process of medium-sized cruise ships, a kind of cabin module lifting device is studied and designed. According to the basic requirements of the actual operation and the characteristics of the cabin module, the design idea and theory are put forward. The solid work software is used for modeling, and then the finite element analysis is carried out through the ANSYS Workbench software according to the actual two working conditions to get the calculation results. The calculation results show that the cage can be used for lifting cabin module, and it can be used repeatedly, with low cost, convenience, rapidity, safety and reliability.
