RIGG ING & ATTACH CHME MENT NTS SHACKLES SHACKLE USE, CARE & INSPECTION SHACKLES Improper use or care of shackles can result in bodily injury or property damage. Always observe the following guidelines when using shackles. • Do not exceed the working load limit. • Do not shock load. • Do not side load – center line of load must coincide with the center line of the shackle. Shackles are designed and rated for in-line applied tension. You can attach multiple slings in the body of a shackle without reducing the capacity provided that the shackle is symmetrically loaded and the included angle does not exceed 120 degrees. (See Side Loading and Symmetrical Loading sections). • Do not replace pin or bolt with other than original equipment. • Inspect before use for wear, deformation and pin engagement as outlined in ASME B30.26. (See full inspection guidelines below). Care should be exercised so that the shackle is not abused during use. When using shackles, it is important to: • If necessary, use spacers on the shackle pin to assure that the shackle is not loaded at an angle. Load line of action should be through the center line of the shackle body and the middle of the shackle pin. • The shackle should be protective coated with zinc plating or a galvanized finish if used in harsh environments. • The shackle should not be subjected to high or low temperatures that could affect thermal treatment and the strength of the shackle. (Note: Per ASME B30.26 shackles are rated for temperatures between -40°F to 400°F. SCREW PIN TIGHTENING When tightening screw pins, it is important that shackle screw pin threads and the tapped threads in the shackle head are clean and free of burrs and damage. These conditions can cause an under-tightening of the shackle screw pin. The shackle screw pin should be be tightly fitted into the shackle's leg opening until the treads engage and the shoulder of the screw pin makes contact with shackle body. SIDE LOADING When side loading a shackle with a single sling, the rated WLL will be reduced in accordance with the manufacturer’s recommendation of a qualified person. ASME B30.26 also recommends reducing the capacity of a shackle when it is side loaded. (See figure below.) Note that only anchor shackles, like the one shown right, should be side loaded. Chain or “D” shape shackles should not be side loaded.

Smart ID makes shackle inspection more efficient and effective, allowing you to easily associate detailed inspection information with every shackle so you know they’re safe to use. Smart ID also increases your productivity by enabling faster inventory tracking and serialization.

Shackles should be discarded if any of thefollowing conditions are apparent: Any parts are worn more than 10% of the original dimensions Load bearing components are bent, twisted, distorted, stretched, elongated, cracked or broken Excessive pitting, corrosion, nicks or gouges Indication of heat damage Missing or illegible manufacturer’s name or trademark, working load limit or size Load pins have bent or visibly damaged threads Cotter pins or hairpin retainers are damaged CHAIN & RIGGING ATTACHMENTS (CMRP-6) 46 PHONE: 800.888.0985 WWW.CMWORKS.COM
RI GGIN ING & ATTACHMENTS SHACKLES CHARPY IMPACT TEST The Charpy V-Notch Test was developed during World War 2 to test the penetration resistance of steel armor. It has since evolved into a method to test for toughness of steel in critical structures such as buildings or bridges. In this test, a bar is mounted horizontally with the notch facing away from an impact weight suspended on a pendulum. When the weight is released, it swings down and breaks through the bar. An indicator measures how far the pendulum continues to swing after breaking the bar. The momentum of the pendulum is then the measure of the resistance of the material to breaking or penetration. CM Super Strong shackles, with the lower hardness values, will consistently pull more than a competitor’s carbon shackles of the same diameter. CM Super Strong shackles were designed to improve overall load strength and ductility without an increase in shackle diameter. CM alloy shackles will meet the Charpy Impact Test requirements. Results of this testing show that CM alloy shackles greatly exceed the minimum strength requirements. Applied Load in Pounds (Thousands) RESULTS OF COMPARISON TESTING CM SUPER STRONG SHACKLES VERSUS STANDARD CARBON SHACKLES 90 80 70 60 50 40 30 20 10 0 The Comparative Strength of the Shackles Loaded in Tension 1/2" Super Strong Shackle 1/2" Carbon Shackle 3/4" Super Strong Shackle 3/4" Carbon Shackle “Clearly the CM Big Orange ® * shackles exhibited superior strength and more ductility than the carbon steel shackles of the same nominal section size. While all of the shackles performed above their ratings, the CM Big Orange shackle performance was superior. The CM Big Orange ® * shock test results indicated severe deformation occurred but no fracture was present. The carbon steel parts fractured in two tests and were severely cracked in a third test. These results indicate that the CM Big Orange shackle assembly is stronger and more ductile than the carbon steel shackle of the same size. For these reasons, the CM Big Orange shackle provides more extensive deformation prior to fracture. In conclusion, this test demonstrates the superiority of the CM Big Orange shackles when compared to the carbon steel shackles under the shock loaded conditions.” Verified by John Bloodsworth, P.E. Q.C. Metallurgical Laboratory, Inc. * CM Big Orange ® shackles are now referred to as CM Super Strong shackles.
