What is the Best Wire Rope for Heavy Lifting and Rigging
2025-11-21
When your project demands absolute reliability, selecting the best wire rope for heavy lifting and rigging is not just a choice—it's a critical safety and operational decision. At LIG MARINE GROUP, we engineer our ropes to meet the extreme demands of marine, construction, and industrial applications. The ideal rope combines immense strength, superior fatigue resistance, and robust corrosion protection to ensure both performance and longevity on your most challenging job sites.
Our flagship product for heavy-duty applications is designed with precision to deliver unmatched performance. Key features include:
-
High-Tensile Core: A durable independent wire rope core (IWRC) provides superior strength and resistance to crushing under heavy loads.
-
Advanced Steel Grade: Manufactured from extra-high-strength improved plow steel (EHS IPS), offering an exceptional strength-to-weight ratio.
-
Enhanced Protection: Features a thick, hot-dip galvanized coating to combat harsh marine and industrial environments, significantly extending service life.
-
Optimized Construction: A 6x36 class wire rope with a Lang’s lay design offers an excellent balance of flexibility, abrasion resistance, and fatigue life.

Wire Rope FAQ
What is the difference between 6x19 and 6x36 wire rope construction?
A 6x19 construction (19 wires per strand) is generally stiffer and more resistant to abrasion, suited for general-purpose use like guylines. A 6x36 construction (36 wires per strand) uses many finer wires, making it more flexible and fatigue-resistant, which is ideal for applications involving sheaves and drums in heavy lifting and rigging.
How often should I inspect my wire rope?
Regular inspection is crucial for safety. A pre-use visual inspection should be conducted daily. A more detailed monthly inspection by a competent person is recommended, with comprehensive quarterly examinations. Any exposure to shock loads or visible damage like broken wires, kinks, or corrosion warrants immediate, thorough inspection and potential replacement.
Why is an Independent Wire Rope Core (IWRC) preferred for heavy lifting?
An IWRC is a separate, smaller wire rope that serves as the core. It provides greater structural stability and support for the outer strands, significantly increasing the rope's resistance to crushing and deformation under heavy loads. This results in higher strength and improved durability compared to a fiber core.
