Elevator is a specific vehicle ment to transport people and cargo. Long interstorey conveyance in tall buildings and deep mines With the help of elevators became possible. It is a distinction of elevator from any other vehicles that any passenger inside may operate it. This is possible due to development of automation. Elevator is considered to be a complex of electromechanical equipment, thus its constructional design is an object of stringent requirements provided by Rules of installation and safe operation of elevators. From the beginning of installation and until the end of elevator usage, it is crucial to meet the requirements of the Rules to ensure passengers’ safety. There are two types of elevators: the electric and the hydraulic ones. The most commonly used type is naturally elect
