Inspecting Synthetic Slings

Mines Safety Bulletin - Inspecting Synthetic Slings

Our onsite inspection services performed by qualified personnel ensure the lifting and rigging gear such as chains, slings, flexible steel wire rope and lifting attachments are safe to use, free from defects and conform with Standards Australia. To prevent any accidents, lifting gear or attachments that are deemed defective, damaged or faulty is immediately withdrawn from service until it is repaired or disposed of.

Examples of Damage

Synthetic Slings

Missing or eligible Safe Working Load (SWL) tag, broken fibres/strands, burns or abrasions, stretched/damaged sleeve, damaged fitting or stitching.

Flexible Steel Wire Rope

Kinks, crushing, bird cage, corrosion, damaged end fittings, heat damage [discolouration], missing SWL tag, broken wires, core collapse and stretched or overloaded.

Chain Slings

Wear, nicks or gouges, cracks in link welds, spot-welding, stretching (more than 10% difference in link diameter), twisted or bent links, lack of link flexibility, missing or eligible Working Load Limit (WLL) tag, makeshift repairs and excessive heat damage.

SWL Tags Must Include

  • Manufacturer/serial number for traceability
  • Product specifications—including material, diameter, weight, design category
  • Safe Working Load
  • Lifting capacities for different sling hitches and sling angles

Considerations Regarding Storage Conditions

  • clean
  • dry
  • out of direct sunlight
  • well ventilated
  • under cover
  • away from chemicals, oils, sand and grit and machinery

Inspection Frequency

The lifting gear and attachments should generally be inspected every three months, or more frequently if subjected to severe conditions. The equipment must be in accordance with the relevant Australian Standard and manufacturer’s specifications.
