Rigging HardwareShacklesScrew pin anchor styleScrew Pin Anchor/Chain Shackles allow quickand easy removal of the screw pin and can beuseful in applications where the shackle isfrequently removed, but not so much inapplications where the pin is subject to torqueor twisting or cyclically loaded.How tight does the pin need to be?The pin must be tightened hand tight or until pinhead is fully seated against the body of the shackle.It may be necessary to tighten an additional 1/8 turnto ensure proper engagement. Do not back thepin off the body of the shackle.Screw pin shackles continued MOUSE TAIL SHACKLE IF IT REMAINS INPLACE FOR ANY EXTENDED PERIOD OF TIME.THIS WILL PREVENT PIN FROM BACKING OUTBolt & Nut Cotter Anchor styleProvide the most secure pin arrangement andwill resist axial loading and torsional loading, butshould only be used in applications whereshackle is infrequently or never removed.Round pin chain Anchor styleAllow easy removal of pin by removing cotter pin andperform well where pin is subject to torque or twisting,but not so much in applications where pin is subject toan axial load. Do not use for Rigging!!CMCO:Rigging TrainingCopyright 20102

They provide a positive attachmentfor slings, hoists or cranes to connect to load.BOLT NUT COTTERTYPE SHACKLEDO NOT SIDE LOAD ROUND PIN SHACKLESANGLE OF SIDE LOAD00 VERTICAL OR IN LINE 100% WLL450 70% WLL900 50% WLLVERTICAL(IN LINE)LOAD900 LOAD450 LOADSYMMETRICAL LOADINGShackles symmetrically loaded with twolegs at maximum angle of 1200 can beused to full working load limit.CAUTION: Round pin anchor shacklesand round pin chain shackles that onlyuse cotter pins for retainers must not beused for overhead lifting. The retainersare not designed to withstand the loadapplied on them in a rigging application.CMCO:Rigging TrainingCopyright 20101200MAXIMUMDO NOT EXCEED 1200INCLUDED ANGLEWHEN USINGMULTIPLE SLING LEGS3
