Abstract

We provide escalator maintenance services to keep the condition of escalators optimal. The handrails that passengers grip when they get on/off the escalators are important parts for their safety. However, in rare cases, aged deterioration of reinforcing steel cords in the handrails make them break and come out of the handrails, and passengers might get injured. But we cannot inspect the codes directly, because they are embedded in the handrails. So we have developed a new diagnostic device to inspect the codes indirectly using the magnetic leakage flux test method.
