Abstract
Crane inspections of the ceiling area of the drive system, and continuous rotation for a short time, the inspection is difficult to check while driving in the quantitative portion of rotation. The timing of replacing the wire rope, Hanging record number of crane operators are determined on the basis of the challenges in life, leaving an estimated accuracy. So, in the hot metal crane equipped with an online vibration diagnosis system and the load frequency of wire rope for the first time. Rainflow method applied to the structure of the crane fatigue damage and estimate the diagnostic system is proposed.
