Products Description
35Wx7 Non-rotating Steel Wire Rope is a premium multi-layer counter-twist rotation-resistant steel cable, specially engineered to eliminate twisting, spinning and load rotation under heavy lifting tension. Built with 35 strands (7 wires per strand) in contra-helical multi-layer laying structure, this rope neutralizes internal torsional force from opposite twist directions, delivering near-zero rotation performance for high-lift, high-precision hoisting scenarios.

Main Application Scenarios
Construction Machinery Sector
In tower crane main hoisting ropes, mobile telescopic boom cranes, crawler cranes, and rotary drilling rig main lift lines, the 35Wx7 Non-rotating Steel Wire Rope enhances working-at-height safety and extends replacement intervals, making it a core consumable accessory for large-scale construction equipment.
Marine and Offshore Operations Sector
Suitable for offshore platform cranes, port quayside ship-to-shore (STS) cranes, ship cargo hoisting, and offshore heavy-lifting systems. The 35Wx7 Non-rotating Steel Wire Rope withstands harsh marine environments including humidity and salt spray, ensuring efficient and continuous operation of offshore operations.
Mining and Heavy Industry Sector
Used in deep-shaft cage hoisting, heavy workshop overhead crane transport, and large steel structure installation under heavy-load conditions. This product excels in anti-rotation performance, effectively reducing the risk of tangled ropes and overwinding during multi-layer spooling, thereby significantly improving the reliability and operational efficiency of frequent hoisting tasks both underground and in workshop settings.
Special Engineering and Precision Lifting Sector
Designed for projects with extremely high demands for non-rotational stability under load, such as super-tall building large-component installation and precision equipment alignment. The 35Wx7 Non-rotating Steel Wire Rope provides micron-level sway control, helping construction teams achieve difficult one-time positioning and reducing secondary adjustments-making it an indispensable lifting tool for high-end specialized engineering.
Quality Assurance
Every batch undergoes strict third-party testing (SGS, BV).
Raw material traceability, full production process quality monitoring, comply with international lifting safety norms
suitable for continuous heavy-duty industrial production with low maintenance cost and high operational safety coefficient.
