Ordinary and Lang's lay describe the manner in which the wires are laid to form a strand of the wire rope. To determine which has been used first identify if left or right hand lay has been used to make the rope. Then identify if a right or left hand lay has been used to twist the wires in each strand.
| Ordinary lay | The lay of wires in each strand is in the opposite direction to the lay of the strands that form the wire. |
| Lang's lay | The lay of wires in each strand is in the same direction as the lay of the strands that form the wire. |
| Alternate lay | The lay of wires in the strands alternate around the rope between being in the opposite and same direction to the lay of the strands that form the wire rope. |
| Regular lay | Alternate term for ordinary lay. |
| Albert's lay | Archaic term for Lang's lay. |
| Reverse lay | Alternate term for alternate lay. |
| Spring lay | This is not a term used to classify a lay as defined in this section. It refers to a specific construction type of wire rope. |
The specification of a wire rope type - including the number of wires per strand, the number of strands, and the lay of the rope - is documented using a commonly accepted coding system, consisting of a number of abbreviations.
This is easily demonstrated with a simple example. The rope shown in the figure "Wire rope construction" is designated thus: 6x19 FC RH OL FSWR

When the wire rope is terminated with a loop, there is a risk that the wire rope can bend too tightly, especially when the loop is connected to a device that spreads the load over a relatively small area. A thimble can be installed inside the loop to preserve the natural shape of the loop, and protect the cable from pinching and abrasion on the inside of the loop. The use of thimbles in loops is industry best practice. The thimble prevents the load from coming into direct contact with the wires.
Swaging is a method of wire rope termination that refers to the installation technique. The purpose of swaging wire rope fittings is to connect two wire rope ends together, or to otherwise terminate one end of wire rope to something else. A mechanical or hydraulic swager is used to compress and deform the fitting, creating a permanent connection. There are many types of swaged fittings. Threaded Studs, Ferrules, Sockets, and Sleeves a few examples.
SocketsA socket termination is useful when the fitting needs to be replaced frequently. For example, if the end of a wire rope is in a high-wear region, the rope may be periodically trimmed, requiring the termination hardware to be removed and reapplied. An example of this is on the ends of the drag ropes on a dragline. The end loop of the wire rope enters a tapered opening in the socket, wrapped around a separate component called the wedge. The arrangement is knocked in place, and load gradually eased onto the rope. As the load increases on the wire rope, the wedge become more secure, gripping the rope tighter.
