Label Elevator

Quick answer：

Elevators are vertical transport devices that move people or goods between floors of a building. They are equipped with a platform, usually called a car, which travels within a compartment. Elevators are powered by electric motors and controlled by a system of switches, buttons, or a keypad. They are commonly used in multi-story buildings, skyscrapers, and public transportation systems. Elevator safety features include emergency brakes, fire modes, and automatic descent to the lowest floor in case of power failure.
