19×19 Compacted Rotation-Resistant Wire Rope – EIPS IWRC
This 19×19 compacted rotation-resistant wire rope is engineered for lifting and hoisting applications where minimizing load rotation is critical. Manufactured from Extra Improved Plow Steel (EIPS) and featuring an Independent Wire Rope Core (IWRC), this rope combines excellent strength, flexibility, and durability with enhanced resistance to crushing, abrasion, and wear.
Compacted Wire Rope for Improved Strength & Service Life
During the manufacturing process, the strands are drawn through a series of compacting dies and rollers that reduce the rope diameter and smooth the outer surface. This compacted construction increases strength compared to a non-compacted 19×19 rope of the same diameter while also improving spooling performance.
The smoother profile reduces surface wear and improves resistance to crushing and abrasion, helping extend the service life of the wire rope in demanding operating conditions.
Category 2 Rotation-Resistant Construction
The 19×19 construction is specifically designed to reduce rope rotation under load. The inner strands are laid in the opposite direction of the outer strands, allowing rotational forces to counteract one another. This makes the rope particularly effective for hoisting unguided loads and applications where load spin can affect safety and performance.
With more than 10 outer strands, this rope is classified as a Category 2 Rotation-Resistant Wire Rope, providing greater rotation resistance than Category 3 constructions such as 8×19 spin-resistant wire rope.
19×19 Wire Rope Configuration
This wire rope is manufactured from EIPS (Extra Improved Plow Steel), providing approximately 10% greater tensile strength than standard IPS-grade wire rope for increased breaking strength and performance.
The 19×19 construction consists of 19 outer strands, with each strand containing approximately 15-26 individual wires. This design delivers a combination of flexibility, handling ease, and rotation resistance.
Bright Finish & IWRC Core
The bright steel finish is uncoated and protected with an A-1 petroleum-based lubricant applied to both the internal and external wires. This lubrication helps reduce friction, minimize internal wear, and provide basic protection against moisture and corrosion.
The Independent Wire Rope Core (IWRC) delivers superior support compared to fiber core constructions. It provides increased resistance to crushing, improved dimensional stability under load, and better performance in elevated temperature environments. Typical operating temperatures range from -40°F (-40°C) to 400°F (204°C).
