An escalator is a moving staircase that helps people travel between different levels of a building, like in shopping malls or train stations. It consists of a series of steps that continuously move up or down, making it easier for people to reach their destination without having to climb stairs. Escalators are especially useful for those carrying heavy items or for individuals with mobility challenges. Escalators are powered by electric motors and have safety features like handrails and emergency stop buttons. They are often found alongside elevators and staircases, providing a convenient option for navigating busy spaces. With their smooth operation, escalators save time and energy for everyone.
