According to the remarkable advances in electromagnetic detecting technique for steel wire rope, it becomes possible to estimate with higher accuracy the static strength of wire rope being used. In addition to this, it is very important to know the dynamic tension loaded on the wire rope during winding.
From these considerations, the authors tried to prepare a tension meter of right-angled triangle type. The reliability and accuracy of this equipment was examined in the laboratory. And afterwards, it was also tested to measure the dynamic tension of the wire rope being used in the inclined and vertical shafts in a coal mine.
From these results, it was confirmed that this equipment is suitable for the practical use: the dynamic tension of vibrating wire rope can be measured accurately.
