Each rung round bracket hinged top places. Under the escalator comb plate mounted on top of the motor, design escalators, moving drive hinge rung. When rung ladder came at the end, Qingyun escalator, will be transformed into flat row passengers to leave, then after the comb plate and then transferred back down in the end, to the other direction, becoming an endless circle. Some of the new escalator side panels made of glass, we can clearly see that the mechanical construction. As both sides of the armrest, is like a rubber manufacturing, in addition to the drive wheel, and to keep pace with the rung is consistent. Modern technology made escalator worm gear box, using Schindler patented technology enables load spreading throughout the tooth surface to a large contact surface; smooth engagement, escalator maintenance, ensure exceptionally low noise; friction reduction, provided than the usual conventional worm gear drive greater drive efficiency, escalators specifications, greatly extended service life. Worm gear traction machine, together with the structure of the three options with different widths cascade of small size, properly handle contradictions good traffic rate and minimum space requirements.
