Abstract
With the increase in the number of elevator installation, it is important that the accuracy inspection and work efficiency are improved. In this study, in order to develop a remote maintenance inspection system of wire rope for structure, an inspection device was first mounted for evaluating structural integrity and an elevation mechanism (probe climber) was fabricated which was capable of even vertical automatic movements. This study considers the detection accuracy after configuring a sensor system of Giant Magnetic Resistance sensor-array which is more compact and accurate in detection than conventional products describes the evaluation results through experiments for identifying the locations of damage in conjunction with a drive control system of the automatic elevation device. We did experiments probe climber that elevates the wire rope with five concentrated damages to 50cm interval. As a result, it was able to identify the locations of damage and detect concentrated damages.
