An elevator is a platform that is used for lifting people up and down in the buildings. Elevators are part of almost all commercial and residential buildings.It is a vertical transport vehicle that efficiently moves people or goods between floor of a building. Elevators are generally power by electric motors that drive traction cables and counter weight with the help of motors.The overall control is done by control system. Key parts of elevator are: .One or more cars(metal boxes) that raise up and down. .Counter weight that balance the car. .An electric motor that hoist the car up and down,including a braking system. .A system of strong metal cable and pulley running between the car and the motor.
