Efficiency ratings for wire rope end terminations are based upon the catalog breaking strength of wire rope. The efficiency rating of a properly prepared loop or thimble-eye termination for clip sizes 1/8˝ through 7/8˝ is 80%, and for sizes 1˝ through 3-1/2˝ is 90%.
The number of clips shown (see Table 1) is based upon using RRL or RLL wire rope, 6 x 19 or 6 x 37 Class, FC or IWRC; IPS or XIP. If Seale construction or similar large outer wire type construction in the 6 x 19 Class is to be used for sizes 1˝ and larger, add one additional clip. If a pulley (sheave) is used for turning back the wire rope, add one additional clip.
The number of clips shown also applies to rotationresistant RRL wire rope, 8 x 19 Class, IPS, XIP, sizes 1-1/2˝ and smaller; and to rotation-resistant RRL wire rope, 19 x 7 Class, IPS, XIP, sizes 1-1/2˝ and smaller.
For other classes of wire rope not mentioned above, we recommend contacting Crosby Engineering at the address or telephone number on the back cover to ensure the desired efficiency rating.
The style of wire rope termination used for any application is the obligation of the user.
