Title:
予測され得る破壊の事前警告インジケータを備えたスリング
Document Type and Number:
Japanese Patent JP2008542154
Kind Code:
A
Abstract:
A pre-failure warning indicator is provided for use with a sling. The pre-failure warning indicator triggers at a point that is predictable within a relatively narrow range, thereby increasing the possibility that a damaged sling is removed from use. The pre-failure warning indicator includes a dedicated strand of material that is placed in close proximity to the load-bearing core yarns of the sling but remains separate and independent from the core yarns; the ends of the dedicated strand are connected via a sacrificial "ring." A warning fiber having an end that is visible to operators/riggers works in conjunction with the sacrificial strand and the ring. The ring is designed to fail when the sling is subjected to a specifically chosen condition (e.g., excessive weight). The failure of the ring causes the warning fiber to withdraw from the rigger's view thereby warning the rigger that the sling was subjected to the specifically chosen condition and may be damaged.
