Product Overview

Its 6-strand compacted construction—formed by cold-pressing strands to reduce gaps between wires—boasts a high metal fill factor (over 90%), delivering superior strength-to-weight ratio compared to standard non-compacted ropes. Available in diameters from 8 mm to 150 mm, it offers tensile strength ranging from 1770 MPa to 2160 MPa, meeting international standards such as ISO 9001, CCS, and ABS. Designed for multi-layer drum winding, this rope excels in applications requiring resistance to crushing and lateral pressure, making it a top choice for heavy machinery and mining operations.

Product Features

Compacted Strand Technology Advantages

High Metal Fill Factor: Cold compaction eliminates wire gaps, increasing the rope’s cross-sectional metal area by 12-15%—this boosts breaking strength and reduces wear from drum contact.

Smooth Outer Profile: The compacted strands create a flat, uniform outer surface that minimizes friction on pulleys, lowering equipment maintenance costs by 20% compared to standard ropes.

Performance & Durability Highlights

Crush Resistance: The dense strand structure withstands lateral pressure up to 500 N/mm², preventing deformation during multi-layer coiling on heavy crane drums.

Anti-Fatigue Properties: Heat-treated wires and optimized strand lay reduce stress concentration, enabling the rope to endure over 10,000 repeated load cycles without fatigue failure.

Applications

Heavy Machinery & Construction

Specialized for crawler cranes, tower cranes, and hydraulic excavators—where multi-layer drum winding and heavy load lifting (50-500 tons) are required. Its crush resistance ensures stable performance in high-lift construction projects (e.g., skyscraper building, bridge assembly).

Mining & Industrial Lifting

Widely used in mining hoists (underground ore lifting), port container cranes, and steel mill slab handling. The high abrasion resistance makes it suitable for harsh mining environments with dust, gravel, and constant drum friction.

FAQ

How does compacted strand technology differ from standard strands?

Compacted strands are cold-pressed to eliminate wire gaps, increasing strength and reducing wear; standard strands have loose wire arrangements that are more prone to abrasion and crushing under heavy loads.

Can this rope be used in marine environments?

Yes, optional hot-dip galvanization or zinc-aluminum coating provides marine-grade corrosion resistance, making it suitable for offshore cranes or port container handling.

What is the weight per 100 meters for a 50 mm diameter rope?

A 50 mm 6-strands compact-strand rope weighs approximately 980 kg per 100 meters, balancing high strength with manageable handling weight for crane operations.
