2、o the furbishment facility, the segment began to slide out of the confines of the handling sling. Approximately 90% of the segment was suspended 10 to 15 feet above the rail car when the aft end of the segment slipped out of the sling, coming to rest on the rail car. The forward end of the segment s
3、tayed suspended approximately 10 above the rail car. No damage to the segment was noted and the rail car received only three scratches by the handling ring. The instability of the segment is due to the difficulty in determining its center of gravity.Lesson(s) Learned: Determining the center of gravi
4、ty of spent booster segments prior to a lift operation is very difficult, often allowing dangerous conditions to exist.Recommendation(s): Design a handling sling device that will self-adjust to the load as it is lifted and keep it steady throughout the lifting operation.Evidence of Recurrence Contro
