• Compression Hardware (wire rope clips, wedge sockets)
• Links, Rings, and Swivels • Rigging Blocks

• Te sling should then be given a thorough, systematic examination throughout its entire length, paying particular attention to sections showing the most wear.
• Special attention should also be paid to fittings and end attachments, and areas of the sling adjacent to these fittings.
• When the worst section of a sling has been located, this area should then be carefully checked against the OSHA and ASME criteria.
• Keep records of inspections that include dates and corresponding conditions of slings.
• Immediately dispose of slings that are rejected. #5
Broken or Damaged Rigging Hardware
With rigging hardware, what we’re talking about is items like hooks, links, shackles, turnbuckles, eye bolts, and hoist rings. Te most common problems tie back to misuse and abuse and lack of inspection. Some of the most common issues we see are:
• Hooks with missing or broken latches • Rigging hardware that’s bent, stretched, broken, or chopped in half
• Items that have been “repaired” or modified through welding
• Shackles using the wrong size or improperly rated pins • Hoist ring bolts that are locked up or “frozen” due to an overload
If you’re unfamiliar with best practices, inspection,
and removal from service criteria for detachable rigging hardware, then you should purchase ASME B30.26 – Rigging Hardware. Tis standard covers:
• Shackles • Adjustable Hardware (turnbuckles, eye nuts, swivel hoist rings)
Homemade or Unmarked Below-the-Hook Devices
One of the most common issues found during a rigging inspection, are custom below-the-hook lifting devices that are either homemade or unmarked. In the below-the- hook lifting world there are two main standards that you should familiarize yourself with if you’re purchasing or designing an engineered below-the-hook lifting device: ASME B30.20
Below-the-Hook Lifting Devices – addresses structural and mechanical lifting devices, vacuum lifting devices, operated close proximity lifting magnets, remotely operated lifting magnets, and scrap and material handling grapples. It offers comprehensive solutions applying to the marking, construction, installation, inspection, testing, maintenance, and operation of equipment used for attaching loads to a hoist. ASME BTH-1 Design of Below-the-Hook Lifting
Devices – provides minimum structural and mechanical design and electrical component selection criteria for ASME B30.20 below-the-hook lifting devices. Making sure that the below-the-hook lifting device
is properly marked and tagged in accordance with the industry guidelines, then you’ve gone a long way towards making sure your below-the-hook devices are OSHA and ASME compliant. Too often we find that below-the-hook lifters have been made in-house and lack a tag or plate that provides the following information on the specific device:
• Manufacturer’s name and contact information • Serial number (unique to that specific lifter) • Lifter weight • Rated load • Cold current amps (when applicable) • Rated voltage (when applicable) • ASME BTH-1 Design Category • ASME BTH-1 Service Class
Tis information can be critical for any rigger, as it WIRE ROPE EXCHANGE NOVEMBER–DECEMBER 2018 29
