Description
Non-Rotating Multi-Strand Crane Wire Rope (35Wx7 / 18×7)
Sino East Steel Group produces premium Non-Rotating Multi-Strand Crane Wire Ropes (35Wx7 and 18×7+IWRC) engineered specifically for high-lift tower cranes, mobile crawler cranes, harbor gantry cranes, offshore deck cranes, and deep mining winches where unguided hoisting requires zero torque spinning.
- Anti-Twist Technology: Counter-laid multi-layer strands generate zero rotational torque under full suspended load.
- Constructions: 35Wx7 (Compact multi-strand), 18×7+FC, 18×7+WSC, 18x19S+IWRC
- Diameter Range: 8.0 mm to 42.0 mm
- Tensile Grades: 1960 N/mm² (EIPS) and 2160 N/mm² (EEIPS)
- Compact Wire Drawing: High metal fill factor with smooth cylindrical outer contact surface for extended sheave life.
- Standards Compliance: EN 12385-4, ISO 2408, GB/T 20118, DIN EN 12385

2. Lubrication & Drum Spooling
Our crane wire ropes are pre-lubricated with high-grade synthetic wire rope grease (e.g., Elaskon / Nyrosten) providing internal strand protection and thermal stability under extreme temperature ranges (-40°C to +80°C). Supplied with solid steel or reinforced wooden reels designed for smooth crane drum reeving.
3. FAQ
Why is 35Wx7 considered rotation resistant?
35Wx7 features three layers of outer and inner strands laid in alternating opposite directions (Lang lay and Regular lay). Under tension, the rotational forces of outer and inner layers counterbalance each other, eliminating hook spin.
Can you provide ropes with fused and tapered ends for easy reeving?
Yes. We provide factory fused, tapered, and welded ends with pulling eyes to enable fast, tangle-free crane reeving through boom head sheaves.
