The maintenance of a lift system, which is a highly specialized machinery, requires professionals with a wide range of knowledge in the mechanical maintenance area. While obtaining accurate information about lift malfunction has grown difficult, this study has filled the gap by compiling management-maintenance problems and operational lift system defects. The general objective of the study is to identify the maintainability issues of lift systems. Firstly, interviews with the industry experts- six (6) Facility Managers and two (2) Lift Supplier Personnel were conducted to identify the system operation defects and management issues. The data collected from the interview comprising the system operation defects were then tabulated in a defect library whereby the explanation of the defects was discussed, and the possible causes of the defects. With regard to identify the key challenges in maintaining the lift system, the prime factor that drives a challenge in maintaining the lift system is the deficiency of knowledge and skills among the lift technicians that were sent to do servicing work. In conjunction, the respondents agreed that conducting training with the purpose of improving skills and knowledge and providing a comprehensive maintainability scoring system will be effective in improving the maintainability of the lift system. Finally, responding to the prime challenges mentioned above, by providing a comprehensive explanation of the lift system’s defects, this research paper has theoretically improved the knowledge base on the maintainability of the lift system.
