Wire Rope clipsYOUR SLING AND RIGGING SPECIALISTCROSBY CLIP WARNINGS ANDAPPLICATION INSTRUCTIONS1.Refer to Table I following these instructions. Turn back specifiedamount of rope from thimble or loop. Apply first clip onebase width from dead end of rope. Apply U-Bolt over deadend of wire rope – live end rests in . Tighten nuts evenly, alternatefrom one nut to the other until reaching the recommendedtorque.2.When two clips are required, apply the second clip as nearthe loop or thimble as possible. Tighten nuts evenly, alternatinguntil reaching the recommended torque. When morethan two clips are required, apply the second clip as nearthe loop or thimble as possible, turn nuts on second clipfirmly, but do not tighten. Proceed to Step 3.!G-450(Red-U-bolt)WARNING• Follow OSHA, ASME B30.9 & Manufacturer’s Guidelines.• Use only if trained.• Failure to read, understand, and follow these instructionsmay cause death or serious injury.• Read and understand these instructions before using clips.• Prepare wire rope end termination only as instructed.• Do not use with plastic coated wire rope.• Apply first load to test the assembly. This load should be ofequal or greater weight than loads expected in use. Next, check& re-tighten nuts to recommended torque. (See Table I, this page)Efficiency ratings for wire rope end terminations are basedupon the catalog breaking strength of wire rope. The efficiencyrating of a properly prepared loop or thimble – eyetermination for clip sizes 1/8" through 7/8" is 80%, and forsizes 1" through 3-1/2" is 90%.The number of clips shown (see Table I) is based uponusing RRL or RLL wire rope, 6 x 19 or 6 x 37 Class, FC orIWRC; IPS or XIP. If Seale construction or similar largeouter wire type construction in the 6 x 19 Class is to be usedfor sizes 1" and larger, add one additional clip. If a pulley(sheave) is used for turning back the wire rope, add one additionalclip.The number of clips shown also applies to rotation-resistantRRL wire rope, 8 x 19 Class, IPS, XIP, sizes 1-1/2" andsmaller; and to rotation-resistant RRL wire rope, 19 x 7Class IPS, XIP, sizes 1-3/4" and smaller.For elevator, personnel hoist, and scaffold applications,refer to ANSI A17.1 and ANSI A10.4. These standards donot recommend U-Bolt style wire rope clip terminations.The style wire rope termination used for any application isthe obligation of the user.for osHa (construction) applications, see osHa1926.251.3.When three or more clips are required, space additionalclips equally between first two – take up rope slack – tightennuts on each U-Bolt evenly, alternating from one nut to theother until reaching recommended torque.IMPoRtantApply first load to test the assembly. This load should beof equal or greater weight than loads expected in use. Next,check and retighten nuts to recommended torque. In accordancewith good rigging and maintenance practices, thewire rope end termination should be inspected periodicallyfor wear, abuse, and general adequacy.table IclIP MInIMUM aMoUnt of *toRQUe InsIze no.
