Rotation-Resistant Value of 34×7+FC Wire Rope in Vertical Lifting & Crane Hoisting
The 34×7 construction—composed of multiple strand layers—delivers enhanced rotation-resistance, making it ideal for tower cranes, mobile cranes, construction hoists, and elevator lifting scenarios where torque control is critical to safety.
The fiber core stabilizes the internal lubrication and reduces internal friction during multi-layer winding operations.
Our 34×7+FC rope reduces load torque by up to 35% compared to conventional multi-strand FC ropes, verified through vertical hoist simulation testing.

Enhanced Fiber Core (FC) Absorption for Smooth Operation & Reduced Strand Fatigue
The natural fiber core offers superior lubrication retention and vibration absorption, extending service life in conditions involving repeated bending and multi-direction load shifts.
Its cushioning effect prevents internal wire abrasion during rotation-controlling operations.
We use a high-density, oil-retentive sisal fiber core with 20% higher stability under compression, ensuring smoother layer winding in crane drums.
Request fiber-core performance data to compare durability across different lifting environments.
Optimized Anti-Rotation Performance for High-Precision Lifting Applications
The 34×7 structure provides uniform stress distribution across inner and outer layers, reducing micro-rotational drift that commonly occurs in single-layer strand ropes.
This ensures stable lifting for applications where load swing control is critical.
Our production incorporates synchronized multi-layer strand closing technology, improving rotational balance consistency by 16% compared with traditional multi-layer rope forming.
Contact us for a detailed lifting stability evaluation for your crane or hoist model.
Export-Grade Mechanical Performance & Rigorous QC Controls
Each batch undergoes tensile strength testing, anti-rotation verification, elongation measurement, torsion resistance analysis, and full-diameter calibration.
This makes it suitable for international lifting standards and demanding industrial exports.
We utilize EN 12385-compliant angle-of-rotation testing equipment and inspect torque deviation on every 800–1,000 meters of production.

Engineered for Cranes, Tower Lifts, Marine Hoists & Multi-Layer Winches
The rope performs exceptionally well in vertical lifting systems where rotational stability and bending fatigue resistance directly influence safety and equipment lifespan.
Its low-torque behavior makes it suitable for deck cranes, shipyard cranes, construction hoists, and tower lifts.
Our 34×7+FC rope has been supplied to large construction-engineering contractors in Europe and the Middle East, proving reliable performance in multi-layer lifting conditions.
