FATIGUE LIFE OF TERMINAL ASSEMBLIES

This chart indicates the relative fatigue life of wire rope terminal assemblies utilizing Crosby swage fittings. This comparison is based upon the fatigue testing of assemblies under controlled laboratory conditions and is only intended to indicate a comparison and not to imply a specific fatigue life value.

WIRE ROPE TERMINAL EFFICIENCIES

The following is the approximate efficiency of the various methods of terminating a wire rope utilizing Crosby-National swage fittings. The efficiency is calculated as the ratio of the ultimate strength of the terminal assembly as compared to the published catalog strength of wire rope. Efficiencies are shown for two types of wire rope; Type I is 6 x 19 and 6 x 37 IWRC EIPS RRL and Type II 6 x 19 and 6 x 37 FC IPS RRL.
