The automatic doors at grocery stores and office buildings mainly exist for convenience. The automatic doors in an elevator, on the other hand, are absolutely essential – they keep people from falling down an open shaft. Elevators use two different sets of doors: doors on the cars and doors opening into the elevator shaft. The doors on the cars are operated by an electric motor, which in turn is operated by the elevator computer. In a relatively short period of time, elevators have become essential to urban life. As people continue to erect monumental skyscrapers and make small buildings handicap-accessible, elevators will become an even more pervasive element in society. It is truly one of the most important – and useful – machines of the modern era.

Door Operator:

Smooth and safe. The door operator must work reliably, day in and day out, to ensure passengers' security The elevator's electric motor turns a wheel, which is attached to a long metal arm. The metal arm is linked to another arm, which opens the door. The door itself slides back and forth on a metal rail. When the motor turns the wheel, it rotates the first metal arm, which pulls the second metal arm and the attached door to the left. The door is made of two panels that close in on each other when the door opens and extend out when the door closes. The computer turns the motor to open the doors when the car arrives at a floor and close the doors before the car starts moving again. Many elevators have a motion sensor system that keeps the doors from closing if a person or object is between them. The car doors have a clutch mechanism that unlocks the outer doors at each floor and pulls them open. This way, the outer doors will only open if there is a car at that floor (or if they are forced open). This keeps the outer doors from opening up into an empty elevator shaft.
