How Many Types Of Escalators Are There?

The escalator consists of a ladder path (a modified plate conveyor) and handrails on both sides (a modified belt conveyor). Its main components include steps, traction chains and sprockets, guide rail systems, main transmission systems (including electric motors, reduction devices, brakes, and intermediate transmission links), driving spindles, ladder tensioning devices, handrail systems, comb plates, ladder frameworks, and electrical systems. The steps move horizontally at the entrance of passengers (making it easier for them to climb the stairs), gradually forming a staircase in the future; As the stairs gradually disappear near the exit, they move horizontally again. These movements are achieved by the main and auxiliary wheels of the steps walking along different guide rails.
