Over the past 30 years, the lift and escalator industry has grown rapidly as a result of the demand for higher buildings and the changing environment. As a result of this, elevator control systems have developed from relay logic to electronic control, where the computerized diagnostic approach is widely applied. The manufacturing of these new products is attributable to the rapid development of new and advanced technology throughout the world. This paper especially highlights the lift and escalator maintenance strategy, comprising Government regulations, different lift cycles of products and parts, quality and safety assurance of maintenance works, education and training of engineers and technical workers, behaviour of users and the different methods of building management etc. These various aspects should be strengthened and subject to enforcement in the future. A strategic plan will be discussed ‘in depth’ in this paper.
