An escalator consists of a ladder road (a deformed plate conveyor) and handrails on both sides (a deformed belt conveyor). Its main components are ladder, traction chain and sprocket, guide rail system, main transmission system (including motor, reducer, brake and intermediate transmission link, etc.) driving spindle, ladder road tensioning device, handrail system, comb plate, escalator skeleton and electrical system, etc. The steps are gradually formed after horizontal movement at the passenger entrance (for passengers to climb the ladder); Near the entrance, the steps gradually disappear and move horizontally again. These movements are realized by the cascade main wheel and auxiliary wheel walking along different stair guides respectively.
