How Does an Escalator Work?

Описание: 📹 Welcome to TheoTheChillOtter ⚙️🪜

An escalator is essentially a moving staircase powered by a motor-driven chain system. Behind the scenes, every step is attached to a continuously rotating loop of chains that are pulled by an electric motor at the top of the escalator. Each step is designed to stay level as it moves up or down, thanks to cleverly placed grooves and guide tracks that keep everything in alignment.

The handrails move in sync, powered by the same motor through a system of pulleys, ensuring riders have consistent support. Escalators are a brilliant mix of mechanical engineering and smart design, efficiently moving people in places like malls, subways, and airports every day.
