Dy-Pac® 18 Increases Rope Performance and Equipment Productivity

  • A resilient 18x19 multi-strand construction and specially selected wire tensiles provide the best strength/performance combination, improving flexibility and rope fatigue life.
  • The Dy-Pac strand compaction process increases the steel area of the individual strands to produce a rope with greater strength, increased lifting capacity and improved rotation resistance.
  • A greater steel area in the rope results in higher crush resistance and significantly enhanced multi-layered drum spooling.
  • 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.
  • Greater contact area between each strand reduces inter strand nicking, which is common for multi-strand constructions, thereby increasing flexibility under load and improving security and performance.
  • Specially formulated lubrication increases rope performance, reduces corrosion and minimizes environmental impact due to fly-off.
  • Well-marked core tracers make it easy to identify Dy-Pac 18 high performance ropes.
  • Full technical support allows WRI customers to make the correct Dy-Pac rope selection, obtain the relevant installation, inspection and maintenance procedures, and receive the necessary training.

Dy-Pac® 18 Reduces Operating Costs and Increases Profits

  • Reduced overall operating costs as a result of significantly enhanced rope performance.
  • Reduced equipment downtime as result of fewer rope change-outs.
  • Lower equipment maintenance costs as a result of reduced sheave and drum wear.
  • Lower inventory costs as a result of reduced purchase requirements.
