Technical Analysis of Moving Walkways

1. Overview of Moving Walkways

Moving walkways, as an essential part of modern transportation systems, are electromechanical devices designed to transport people in a horizontal or slightly inclined direction using a continuously moving conveyor structure. Their primary function is to alleviate pedestrian traffic congestion in public spaces and improve spatial efficiency. These systems typically consist of drive mechanisms, load-bearing structures, safety protection devices, and control systems, serving as an alternative to traditional walking paths in specific environments.
