Thus for, it appears that wire ropes are generally accepted expendable items (in contrast to irreplaceable items) and consequently the handling of wire ropes is somewhat thought lightly upon. Moreover, there is a tendency of twisting due to the great stretch of wire ropes and also become comparatively weak when lateral compression occurs. Consequently there should be caution in its use. The authors of this paper systematically investigated and analyzed an accident of wire rope which occured in Aza port, Naha City. The investigation included the investigation of operation of maintenance of wire rope and the visual identification of the damaged part (pile driver engine, anvil, knob of pile driver engine, pully, damaged wires).

The five points listed above can be considered as the direct cause of the accident.
