Rotation Resistant Ropes For Crane Applications
RRL Dy-Pac Cushion Core
Cushion-Pac® 18 ropes improve performance and operational safety.
- A fully cushioned core, utilizing WRI’s exclusive plastic enhancement process, significantly reduces inter-strand cross cutting throughout the rope’s life and allows for external inspection of operational wear.
- A specially designed 18x19 multi-strand construction, combined with plastic enhancement, locks the core in place to support the outer strands, providing excellent rotation resistance and enhanced in-service stability.
- Dy-Pac strand compaction increases the steel area of the individual strands, producing a rope with improved resistance to crushing, improved drum spooling, and increased lifting capacity.
- A smooth outer strand profile improves rope wear resistance, reduces sheave and drum wear, and allows the rope to run more efficiently on high speed hoisting lines.
- Specially formulated lubrication increases rope performance and reduces the effects of corrosion.
- Well-marked core tracers make it easy to identify Cushion-Pac 18 outperforming ropes.

Cushion-Pac® 8 Ropes
For High-Cycle Crane Applications
RRL Dy-Pac Cushion Core significantly increase rope performance and productivity.
- A proven 8x31 IWRC rope design and specialized construction properties improve flexibility and rope fatigue life.
- Dy-Pac strand compaction increases the steel area of the individual strands, producing a rope with improved resistance to crushing, improved drum spooling and increased lifting capacity.
- A fully cushioned core, utilizing WRI’s exclusive plastic enhancement process, protects the inner rope throughout its cycle life and allows for external inspection of operational wear.
- Greater rope contact area increases rope life and reduces drum and sheave wear.
- Specially formulated lubrication increases rope performance and reduces the effects of corrosion.
- Blue/Green core tracers make it easy to identify Cushion-Pac 8 high performance ropes.
