In the designation 3/4 inch, 6 x 19 - IWRC, what does the number 19 indicate?

In the designation 3/4 inch, 6 x 19 - IWRC, the number 19 refers to the total number of wires that are arranged to form each strand of the wire rope. This type of designation indicates how the wire rope is constructed; specifically, it indicates that there are 6 strands and that each strand consists of 19 individual wires.

The composition of wire rope is critical for understanding its strength, flexibility, and durability. A higher number of wires in each strand generally provides more flexibility and can reduce wear on the rope. Hence, knowing the number of wires is essential for correctly assessing the capabilities and applications of the wire rope, which is particularly important in construction and rigging where safety is paramount.

This understanding of the structural makeup of wire rope helps in selecting the appropriate type for specific lifting or pulling tasks, ensuring safety and efficiency in contracting work.
