Wire rope is a tool made from dozens–even hundreds– of individual wires which are formed and fabricated to move or operate at close tolerances to one another. When a wire rope bends, each of its many wires slides and adjusts to accommodate the differences in length between the inside and outside of the bend. The sharper the bend, the greater the movement will be.

 

Wire ropes are identified by classifications based upon the number of strands and nominal number of wires in each strand. A6 x 19 classification for example, includes six strands with each strand consisting of 15-26 individual wires. The six strands of a 6 x 37 class wire rope are constructed of 27-49 individual wires. Other popular classifications include 19 x 7, 7 x 19 and 8 x 19.
