SOCKETING
Improperly attached wire rope terminals lead to serious-possibly unsafe- conditions. To
perform properly, all wire rope elements must be held securely by the terminal. If this is not
accomplished, the strands will “loaf on the job” and there is every likelihood that a strand
will become “high”. A high strand condition is illustrated in Figure 42. In the case shown,
selective abrasive wear of the loose strand will necessitate early removal of the rope.
Poured Sockets-Spelter or Resin
When preparing a wire rope for socketing, it is of extreme importance to follow
recommended procedures. (See Appendix D: SOCKETING PROCEDURES.) Procedures
other than those stipulated here, may develop the required strength but this cannot be pre-
determined without destructive test. It is far safer-and ultimately less costly-to follow well-
established practices.
There are many ways to go wrong in socketing procedures. Some of the more common
pitfalls that should be guarded against include:
1. Turning back the strands-inward or outward-before the “broom” is inserted into the
socket;
2. Turning back the strands and seizing them to the body of the rope:
3. Turing back the strands and tucking them into the body of the rope:
4. Tying the knot in the rope:
5. Driving nails, spikes, bolts, and similar objects into the socket after the rope is in, so
as to “jam” it tight; this is particularly dangerous-and ruinous.
To avoid these and many other dangerous practices, play it safe by following correct
procedures
