Storage
Storage
  • Single-Wire centre with six wires of the same diameter.
  • Free from moisture, duct and fumes.
  • Suitable lubricant to be applied every 3 months to the outer layers.
  • Reel containing ropes to be rolled through 90 degree after every 3 months.
  • Protect wooden reels from the attack of termites.
  • In no case the reels should be put on ground or uncommented floor.
 
Wire Rope Characteristics

Commonly Used Rope (Non-compacted) Characteristics Simply Stated

  • More wires in the outer strand (14 for 36WS) will improve bend fatigue.
  • Less wires in the outer strands (9 for 19S) improve wear/abrasion resistance characteristics.
  • Steel core (IWRC) IWRC resists drum crushing better than fibre core.
  • Langs Lay resists interference at drum better than ordinary lay.
