An Inspection Technique Research and Instrument Development for Protection against Overspeed and Unintentional Reversal of the Travel Direction of Escalators

This paper introduces a new method and a multi-functional instrument which both based onthe inverter technology.The simulating method is used for inspect the device for protection from overspeed andunintentional reversal of the travel direction of escalators. The instrument can simulate the dangerous workingconditions of the escalator＇s accidental overspeed and unintentional reversal, in order to achieve the qualitative andquantitative inspection. This paper focuses on the principles, features and operating methodes of the instrument.It alsoanalyses the contrastive cases practically comparised with the traditional methodes in detail. For the advantages ofintuition, accuracy, qualitative and quantitative inspection, the instrument has a good solution to the problem of inspectingthe protection against overspeed and unintentional reversal of the travel direction of escalators. This instrument fills avacancy in the area at home and abroad, and reaches the international advanced level.
