The secret engineering behind your escalator's textured steps
In short: Most people assume the ridges on an escalator step are simply for traction. In reality, they serve a more complex mechanical purpose that ensures safety during one of the most critical transitions in modern transit.
While grip is a primary benefit, these deep grooves are essential components of the machine's engineering. They facilitate a smoother and safer transition as passengers move from the moving steps onto stationary floors or vice versa.
By managing how surfaces interact during movement, these ridges prevent slipping and help stabilize the flow of people in high-traffic environments.
