Modern Escalator
Construction of the escalator
Standart features of escalators
1. The button of emergency switching-off of the escalator
At occurrence of an emergency it is possible to interrupt manually work of the escalator by pressing the button
2. The Overload protection
If system will find out, that the escalator is overloaded, it will be automatically stopped
3. A phase failure
If the system will find out failure, that the phase of rotation mismatches a phase of movement or there was a failure on a phase, the escalator will not be started
4. The electromagnetic brake
An Electromagnetic brake — the important factor of safety of passengers, it is intended for warranting an exact stop of the escalator
5. The switch of a comb
The Escalator will stop in case of hit of any subject between a comb and a corrugated flooring of a step
6. Not reversive device of safety
This function stops the escalator if the direction of its movement changes to opposite
7. An overspeed limiter
The function stops the escalator in case of excess of normal speed of movement
8. The protection enclosure of a circuit
Prevents an opportunity of hit of undesirable elements in a circuit
9. Blocking of traction steps of the escalator
Function stops the escalator in case of breakage or a leaky attachment of steps of the escalator
10. The yellow distinctive line at a step
Outlines a safety zone of a finding of the passenger
11. Blocking of a plinth
The escalator stops in case of hit of any subject between a step and a plinth
12. The switch of a mouth of a hand-rail
If a hand of the passenger or any subject is tightened in a mouth of a hand-rail, the escalator stops
13. Blocking drive circuits of the escalator
The escalator stops, if the drive circuit is torn off or too slackened
