Jared Owens uses computer-generated animation (CGI) to show how things work. Escalators are one of his latest topics, and the video he narrates is clear and informative — ideal for children and even adult professionals who want to brush up on their vertical-transportation knowledge. In the video, he provides a brief history of escalators and how the technology evolved, and describes different equipment configurations and the reasons for them. Check it out and get an inside, up-close look at components like step chains, track systems, gears, roller chains and handrails, and they all fit together like a puzzle to enhance efficiency and promote safety.
