Crane wire rope IWR

for miningsteelflexible

Product Overview
The 6×9W+IWR wire rope features a 6-strand Warrington (W) line-contact construction with 9 wires per strand and a steel wire rope core (IWR). It is designed for demanding hoisting and load-bearing applications where high breaking strength and wear resistance are required.

Performance Characteristics

• Strength: The steel wire rope core (IWR) increases overall rope strength and anti-extrusion capacity while preserving the line-contact benefits of the Warrington construction.
• Flexibility: Compared with non-IWR constructions, flexibility is moderately reduced due to the steel core, yet the rope remains suitable for industrial hoisting and heavy-duty applications.
• Wear resistance: The line-contact Warrington profile combined with the IWR core provides enhanced resistance to surface wear and abrasion in high-wear environments.

Application Characteristics
Commonly used as main hoisting ropes for heavy-duty cranes, mine shaft main hoists, high-speed elevator hoisting ropes and other critical lifting systems where strength, fatigue resistance and wear performance are essential.

Marketing Message
When applications cannot compromise on tensile strength, wear resistance or fatigue life, the 6×9W+IWR construction offers a balanced solution; custom configurations and competitive commercial terms can be provided to meet project requirements.
