The results which i have studied to the wire rope in vertical shaft are get together into the report of this grant-in-aid.The main results are as follows:(1) The new equetion which are estimated to the safety factor of winding rope in vertical shaft is proposed. The factor is cosidered to the abnormal dynamic tension and the maximum value of bending stress, following on an emergency braking or rough loading into the cage.(2) The shaft-winding system modelis showed. It can be simultaneously explained to the tension of winding ropes, winding speed, winding load, and other winding codition.
