Abstract
Nine wire rope terminations were pull and fatigue tested to destruction to measure the termination efficiency and relative fatigue life. The terminations were selected on the basis of mine site visits and the specimens were assembled in a manner similar to industrial slings. To measure a termination's sensitivity to poor manufacturing, both standard and modified assembly specimens were tested. In static pull tests rope class, construction, and diameter interacted with the termination to influence the efficiency of the termination. In axial fatigue tests the effect of rope construction was negligible since failure was primarily dependent on the termination type. The swaged socket, a termination requiring a high- capacity hydraulic press, gave the best overall performance in terms of efficiency and fatigue life; the short body length of the zinc- poured socket was attributed with the short fatigue life. The use of thermosetting resins as a replacement for zinc was demonstrated successfully for some socket designs. The fatigue life of the termination, expressed as a percentage of the fatigue life of the wire rope, was shown to be a guide for the retirement of the wire rope where those applications are primarily in axial loading.
