In 1900, Otis at the Paris-France International Fair presented a cascade of escalators. This is the world's first "escalator"

Today, in the major shopping arcades, the escalator becomes indispensable for us to ride the tools and decorate the landscape.

Comb teeth: grooved primary aluminum, bolted to the comb plate. Each comb has a predetermined breaking point, in the event of foreign body broken comb teeth escalator will stop running

Comb tooth board: Comb tooth board strength requires both to withstand the passenger pedal, kick and other loads, but also lower than the pedal tooth strength. When the foreign body is stuck, the deformation that does not affect the normal meshing occurs. Comb tooth plate is wearing parts, requiring easy replacement.
