Wire Rope: Construction
WIRE ROPE CONSTRUCTION
Wire rope is normally constructed of strands and wires.
STEEL CORE: an independent wire rope core (IWRC) adds strength (7&1/2% min) and provides a greater resistance to crushing than fiber core wire rope. Wire rope is normally constructed of strands and wires.
FIBER CORE: This type of wire rope is composed of a natural product such as – manila, jute, sisal, or synthetic products such as – polypropylene. Synthetic products offer the advantage of resistance to rotting, drying out and other forms of deterioration. Fiber core is usually impregnated with lubricant during manufacturing that acts as an internal lubricant.
REMEMBER
Ultimate Load or Breaking Strength Ratings of wire rope applies ONLY to NEW or UNUSED wire rope.
