MOVING HANDRAIL DETERIORATION DIAGNOSTIC DEVICE, MOVING HANDRAIL DETERIORATION DIAGNOSTIC METHOD AND POSITION SPECIFICATION MARK USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a moving handrail deterioration diagnostic device capable of checking an attribution of a passenger conveyor by detection data.SOLUTION: A moving handrail deterioration diagnostic device 12 includes a magnetic flux sensor 13 detecting a magnetic flux from a steel cord positioned inside the moving handrail of a passenger conveyor to detect a damage of the steel cord based on the detected magnetic flux. The magnetic flux sensor detects a magnetic flux from a magnetic object M provided in the moving handrail and including a gap part having a pattern corresponding to an attribution of a passenger conveyor.SELECTED DRAWING: Figure 3
