Steel Wire Rope

Construction of Steel Wire Rope

The design of a rope is determined by:

  • STRAND CONSTRUCTION
    The number and arrangement of wires in each strand
  • ROPE CONSTRUCTION
    The number and arrangement of strands in each rope
  • THE CORE

Wire Rope Lays

Right Hand Clockwise
Left Hand Counter-Clockwise
Regular Lay Wires in strands are laid in the opposite direction of the strands and are parallel to the rope axis. 
Lang Lay Wires are laid in the same direction as the strands of the rope, and in an angle to the rope axis.

Lang lay ropes should only be used where both rope ends are “fixed” and therefore, should not be used with an swivel type terminal.

Grades of Wire Rope

     
Grade 1370 N/mm² Special grade to meet requirements of hoisting rope on traction elevator.
Grade 1570 N/mm² Ungalvanised and drawn galvanized wire for more flexible grade sometimes used for less-demanding applications.
Grade 1770 N/mm²

A common, durable grade used for general engineering, lifting, and mining.
Grade 1960 N/mm² Extra high tensile grade is used in the manufacture of wire rope for high-load applications where higher tensile strength is required.
Grade 2160 N/mm² Used where maximum breaking strength is required for the diameter.
