1Can You IdentifyDamaged and Unsafe RiggingEquipment?Identifying and removing unsafe lifting and rigging equipment is critical to a safework environment and avoiding accidents and costly fines.If you work in a job that uses lifting and rigging equipment, then you should be familiarwith the OSHA and ASME standards that govern the safe use, design, and inspectionof that equipment. Regular inspection of your rigging equipment will help to identifydangerous devices before they cause an accident or near-miss on a job site.800.727.0665induscowirerope.com

2Some of the most commonly referenced safety standards for lifting and riggingequipment are: OSHA 1910.184 - SlingsASME B30.9 SlingsASME B30.26 - Rigging HardwareASME B30.10 - HooksASME B30.20 - Below-the-Hook Lifting DevicesWhile the information in these safety standards is invaluable—especially when it comesto inspection frequencies and removal from service criteria—we often hear that therearen’t enough examples to show end-users real damage to equipment that warrantsremoval from service.When a Rigging Inspector or Lifting Specialist goes on-site for an inspection orconsultation, they sometimes encounter misused, damaged, or downright dangerousequipment that’s still in service and being used for overhead lifts.In this article, we’ll share several real examples of slings, rigging hardware, andhomemade lifting devices that our inspectors have removed during an inspection. We’llwalk you through the reasons each device should be removed from service and identifythe applicable industry standards for each device.800.727.0665induscowirerope.com

3Sling HookWhy should this device be removed from service?At first glance, it’s clear that this hook is deformed. The damage to this hook was mostlikely caused by tip-loading, or overloading the hook, which stretched the throat openingbeyond its original shape.Additionally, due to this deformation, the hook latch no longer reaches the tip of thehook to prevent slings or loads from accidentally slipping off the hook.Relevant Standard(s): ASME B30.10 - Hooks800.727.0665induscowirerope.com

4Synthetic Web SlingWhy should this device be removed from service?This web sling is non-compliant for several reasons. First, slings cannot be used foroverhead lifting with any knots present in the body of the sling.Second, the sling tag is not legible. If the sling tag is missing or illegible, the sling mustbe removed from service.Relevant Standard(s): ASME B30.9 Slings800.727.0665induscowirerope.com

5Non-Standard Lifting HookWhy should this device be removed from service?This lifting hook is homemade and modified by welding an eye bolt to the top of whatresembles a c-hook device. Per the requirements of ASME B30.20 – Below-the-HookLifting Devices, the device appears to be lacking identification that show the serialnumber, manufacturer, load rating, and other vital design information on it.Without any visible identification or markings, there’s no way to know what capacity thisdevice is capable of lifting, and is not compliant for overhead lifting applications.Relevant Standard(s): ASME B30.20 – Below-the-Hook Lifting Devices ASME BTH-1 – Design of Below-the-Hook Lifting Devices800.727.0665induscowirerope.com

6Non-Standard Cylinder Lifting DeviceWhy should this device be removed from service?This is a makeshift device comprised of an eye welded to a cap and was used to liftlarge steel cylinders. The cap is not rated for lifting purposes and the device is weldedtogether and homemade.Per ASME B30.20 – Below-the-Hook Lifting Devices, the device appears to be lackingidentification that shows the serial number, manufacturer, load rating, and othermarkings on it. Without the proper markings and identification, there is no way to knowat what capacity this device is capable of safely lifting.Relevant Standard(s): ASME B30.20 – Below-the-Hook Lifting Devices ASME BTH-1 – Design of Below-the-Hook Lifting Devices800.727.0665induscowirerope.com

7Foundry HookWhy should this device be removed from service?While a foundry hook is a type of lifting hook designed to be used without a latch, this hook hasbeen deformed by overloading or side-loading. There is an apparent twist in the hook as wellas a slight stretch in the throat opening. Both instances of deformation warrant removal fromservice.Relevant Standard(s): ASME B30.10 - Hooks800.727.0665induscowirerope.com

8Modified Eye BoltWhy should this device be removed from service?This eye bolt has been modified with a screw welded to the top of the eye. Not only is thisdevice non-compliant because it’s been modified, the shank of the original eye bolt is bent.Both the modification and deformation of the eye bolt warrant removal from service.Relevant Standard(s): ASME B30.26 - Rigging Hardware800.727.0665induscowirerope.com

9Synthetic Sling ShackleWhy should this device be removed from service?Although this shackle is a little beat up and has some chips in the painted surface, it’s in overallgood shape. This one was a trick question. It doesn’t have any apparent damage that wouldviolate industry standards, and doesn’t require removal from service.The bow shape of a synthetic sling shackle is different than anchor shackles or chain shackles.Synthetic sling shackles have a wider bow to increase synthetic web or roundsling efficiency—resulting in 100% of the sling’s working load limit to be achieved.Relevant Standard(s): ASME B30.26 - Rigging Hardware800.727.0665induscowirerope.com

10ShackleWhy should this device be removed from service?From the photo, it’s difficult to tell whether this is a screw pin, round pin, or bolt type shackledue to excessive damage.The damage to this shackle is obvious, the pin is cracked, bent, and no longer extends fromear to ear. This damage was likely caused by excessively overloading the shackle to the pointof breaking.Relevant Standard(s): ASME B30.26 - Rigging Hardware800.727.0665induscowirerope.com

11Section of Alloy Chain SlingWhy should this device be removed from service?When you look closely at this section of an alloy chain sling, you can see that there are deepgouges in several links. This damage was likely caused from misuse and abuse to the slingand warrants removal from service.Relevant Standard(s): OSHA 1910.184 - Slings ASME B30.9 - Slings800.727.0665induscowirerope.com

12Homemade Lifting Clamp DeviceWhy should this device be removed from service?Neither the web sling nor the clamp are safe for overhead lifting applications. The knotspresent in the sling warrant removal from service. Not only is it non-compliant to place knotsin a lifting sling, but knots are used to connect the clamp to the sling, instead of an approvedmechanical or welded connecting device. The sling also appears to have suffered severe cutsand abrasions, as the eyes are no longer present on each end.While the clamp does not appear to show any excessive damage and shows clearmanufacturer markings, it is not rated for lifting. This type of C-clamp is meant for pressureapplications only.Relevant Standard(s): ASME B30.9 - Slings ASME B30.20 - Below-the-Hook Lifting Devices ASME BTH-1 - Design of Below-the-Hook Lifting Devices800.727.0665induscowirerope.com

13Wire Rope SegmentWhy should this device be removed from service?This image shows a portion of a wire rope sling that displays kinking and broken wires—bothof which are criteria that warrant removal from service.Although a certain ratio of broken wires are permitted, the kink damage alone meets removalfrom service criteria for a wire rope sling.Relevant Standard(s): ASME B30.9 - Slings800.727.0665induscowirerope.com
