Elevators are mechanical devices that transport people or goods vertically between different floors of a building. They operate using a system of pulleys and cables, allowing for smooth and efficient movement. Elevators are commonly found in high-rise buildings, shopping malls, and hospitals, providing accessibility for everyone, including those with mobility challenges. Escalators, on the other hand, are moving staircases that carry people between different levels. They consist of a continuous loop of steps that rotate around a set of gears. Escalators are often used in places like airports, subway stations, and shopping centers, making it easier for people to navigate between floors without the need for stairs.
