The escalator consists of a ladder (variable slab conveyor) and armrests on both sides (deformed belt conveyor). The main components are step, traction chain and sprocket, guide rail system, main drive system (including motor, reducer, brake and intermediate drive link, etc.) drive spindle, ladder tensioning device, armrest system, comb plate, escalator skeleton and Electrical systems, etc.
The steps gradually form a step after the passengers move horizontally (convenient for the passengers to board the stairs); the steps near the entrance gradually disappear, and the steps are horizontally moved again. These movements are realized by walking the main and auxiliary wheels of the step along different step guides.
