The Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) is the largest of this kind in China and it will be put into operation in two years. To secure its smooth operation, each component, especially the mirror system needs to be maintained in a good condition. Some equipment is needed and the operation must be considered at early stages. In this paper, a feasible approach is put forward in which the concept of human and machine cooperative work is used to assure the successful operation at lower cost. An electrical driven forklift with some special fixtures designed for this work is used for MB mirror system and a special designed crane is used for the assembly and disassembly of MA mirror system. Procedures and methodologies for the identification of assembly and disassembly sequence, special tool design, time and cost analysis, and human factors analysis of the assembly and disassembly sequence are presented.
