Rigging information for inspection

INSPECTION OF RIGGING HARDWARE

INSPECTION FREQUENCY PER ASME B30.26

A visual inspection shall be performed by the user or designated person each day before the rigging hardware is used.

A periodic inspection shall be performed by a designated person, at least annually. The rigging hardware shall be examined and a determination made asto whether they constitute a hazard. Records are not required.

Semi-permanent and inaccessible locations where frequent inspections are not feasible shall have periodic inspections performed.

REJECTION CRITERIA PER ASME B30.26

Missing or illegible manufacturer’s name or trademark and/or rated load identification (or size as required)

a or more reduction ofthe original dimension bent, twisted, distorted, stretched, elongated, cracked or broken load bearing components

excessive nicks, gouges, prmng and corrosion

indications of heat damage including weld spatter or arc strikes, evidence of unauthorized welding

loose or missing nuts, bolts, cotter pins, snap rings, or other fasteners and retaining devices

unauthorized replacement components or other visible conditions that cause doubt asto the continued use of the sling

Additionally inspect wire rope clips for:

  1. Insufficient number of clips
  2. Incorrect spacing between clips
  3. Improperly tightened clips
  4. indications of damaged wire rope or wire rope slippage
  5. improper assembly

Additionally, inspect wedge sockets for:

  1. indications of damaged wire rope or wire rope slippage
  2. improper assembly

ADDITIONAL REJECTION CRITERIA PER ASME B30.10 – HOOKS

  • Any visibly apparent bend or twist from the plane ofthe unbent hook
  • Any distortion causing an increase in throat opening of 5%, notto exceed 1/4″

INSPECTION OF SLINGS

INSPECTION FREQUENCY PER ASME B30.9

 A visual inspection for damage shall be performed by the user or designated person each day or shift the sling is used.

 A complete inspection for damage shall be performed periodically by a designated person, at least annually.

 Written records of most recent periodic inspection shall be maintained.

REJECTION CRITERIA PER ASME 30.9

Missing or illegible sling identification; evidence of heat damage; slings that are notted; fittings that are pitted, corroded, cracked, bent, twisted, gouged, or broken; other conditions, including visible damage, that cause doubt as to the continued use of the sling.

WIRE ROPE SLINGS

  • Excessive broken wires, for strand-laid and single part slings, ten randomly distributed broken wires in one rope lay or five broken wires in one strand in one rope lay
  • Severe localized abrasion or scraping, kinking, crushing, birdcaging
  • Any other damage resulting in damage to the rope structure
  • Severe corrosion ofthe rope or end attachments

CHAIN SLINGS

  • Cracks or breaks
  • Excessive wear, nicks or gouges
  • Stretched chain links or components
  • Bent, twisted or deformed chain links or components
  • Excessive pitting or corrosion
  • Lack of ability of chain or componentsto hinge freely
  • Weld splatter

WEB SLINGS

  • Acid or caustic burns
  • Melting or charring of any part ofthe sling
  • Holes, tears, cuts or snags
  • Broken or worn stitching in load bearing splices
  • Excessive abrasive wear
  • Discoloration and brittle or stiff areas on any part ofthe sling, which may mean chemical or ultraviolet / sunlight damage

ROUNDSLINGS

  • Acid or caustic burns
  • Evidence of heat damage
  • Holes, tears, cuts, abrasive wear or snags that expose the core yarns
  • Broken or damaged core yarns
  • Weld splatter that exposes core yarns
  • Discoloration and brittle or stiff areas on any part ofthe slings, which may mean chemical or other damage
