(Including motors, decelerators, brakes and intermediate transmission links, etc.), drive the main shaft, ladder tensioning device, handrail system, comb plate, escalator skeleton, the main components of the main components are stepped, traction chain and sprocket, rail system, And electrical systems. The steps are leveled at the passenger's entrance and gradually form a ladder; the ladder gradually disappears at the exit and the steps are again leveled.
