WebBirdcaging is the separation of the strands of the wire rope is called birdcaging, a result of damage resulting from shock loading. Bent Wire is a common indication of side loading or other abuse. Now the moving parts of the machine (sling) cannot move. The rope will wear out prematurely. Frayed Wire is common when a sling is overloaded or misused. WebSevere twisting or birdcaging in non-rotational wire means that it has been overstressed and should be upgraded. The core in non-rotational rope is relatively larger than in standard IWRC and contains 20% to 30% of the strength of the rope. When splicing 8×19 wire rope, as with all IWRC constructions, the core must be buried in the splice.
