IFE Elevators In Public Transport

When the speed of the handrail deviates from the actual speed of the step (pedal or tape) by more than 15% and lasts for 5~15s, PESSRAE automatically cuts off the safety circuit, and the escalator stops running and reports a fault.

Strengthened thickened steel plate, scientific mechanical calculation, stronger pressure resistance, more suitable for long-term stable work. Multi point fixed clamp design, high strength bolts, anti shearing, anti fatigue and anti loosening. The limit device of the main engine is precisely driven, and the main engine is fixed under the super traction, double preventing the displacement of the driving main engine.

The overspeed protection sensor uses Schneider brand to prevent potential safety hazards caused by excessive running speed of the escalator.

The actual running direction of the escalator is judged by the logic sequence of the pulse signal of the speed sensor to prevent reverse running. If the drive chain breaks and the speed sensor fails, the drive chain protection switch will also act and the escalator will stop running to ensure that there is no risk.

The truss can be treated with hot dip galvanizing for rust prevention. The thickness of the zinc layer on the surface is at least 80 um and the maximum is 110 um, which can effectively ensure the normal use of the ladder/sidewalk truss in various harsh environments.

New design scheme of super span escalator support, large support in the middle, can effectively relieve the load bearing of the whole ladder truss. Scientific mechanical design can increase the stability of long-span truss, with more uniform force and higher stability.
