High-precision worm gear,Helical gear reducer
Public service escalator has to firstly face the challenge of sustained heavy duty, carry high precision worm gear and helical gear reducer as well as highly integrate both advantages of worm gear drive and helical gear drive. Worm and gear can transmit larger moment in relatively small spaces, while helical gear owns low noise, stable drive and good damping.
Their effective combination makes the escalator more efficient to fight against the sustained load pressure.
Unloading guide rail
In the face of upper great tension, the upper bending section of Series HE-Il escalator is equipped with four unloading guide rails to ensure the bearing force is close to zero by separating with guide rail when the roller comes to upper bending section, so as to lower roller wear and lengthen service life.
