An electric monorail system (EMS) is a rail-bound means of conveyance with individually driven vehicles which move independently on the rail system. It is commonly used in transporting goods from horizontal sections at automobile production plants. In recent years, demand for EMS, which can travel on sloping parts, has increased, and EMS for sloping driving has been developed. This development was aimed at replacing existing lifter facilities by developing vertical travelling EMS and ensuring diversity of line composition. This paper deals with market demand research and development planning.
