Performance Evaluation of Maintenance contractor, A case study of Elevator.

Abstract

The major goal of this project is to do research into elevator maintenance issues. This study covers the evolution of elevators, including their history, definitions, and commonly used elevator concepts. Elevators are currently an important part of thousands of people's daily lives, and they will play a big role in the future of urbanization as population density rises and real estate prices fall. Elevators not only provide convenient vertical mobility, but they also play a significant role in providing accessibility for individuals with disabilities, thus their safe and reliable operation is critical. This thesis examines elevator maintenance and safety practices across the country, as well as a study of several elevator-related mishaps in order to recommend safety measures. Modern elevators are very safe in general, but poorly maintained systems, passenger safety vulnerabilities, incomprehensive work instructions, negligence and lack of proper safety protocols still cause several accidents every year. The engineering parameters related to elevator safety such as rated load, rated velocity, brakes, and safety gears are also explored, and a brief study is done about elevator maintenance
