Rigging Inspections
What do I need to know?

Two Required Inspections

  1. Before each use

    All rigging must be visually inspected prior to use to make sure it is free of obvious damage.

    Any damaged rigging must be immediately taken out of service.

  2. Periodic inspections (at least annually)

    Rigging must receive a detailed inspection by a qualified person at least annually. This includes all sling types (synthetic, wire rope, chain), all hardware and all below the hook lifting devices.

    Chain slings are special as their periodic inspection must be documented and this inspection certificate needs to be presented to a WorkSafe Officer upon request.

Common Rejection Damage


  • Edge Damage
  • Face Cuts

Caused by the sling coming in contact with sharp or abrasive loads or slings being pulled from under loads laying on the slings.


  • Broken or Missing Latches
  • Corrosion

Latch damage is often caused by facing hook openings into the load causing weight to press on the latch. Corosion is caused by improper storage.


  • Kinking
  • Broken Wires

Caused by the sling being loaded over sharp edges or around a load with too small a diameter. Full lifting capacity requires the load to be 25 times larger than the rope diameter (D/d). The D/d ratio in the eye of a wire rope sling must be at least 1/1.


  • Exposed Core Strands
  • Internal Lumps

Exposed core is caused by the cover tearing or melting open from contacting sharp edges, abrasive surfaces or heat. Internal lumps are due to shock loading. Some round slings have external indictors of internal damage. For those that don't it is important to feel the length of the core for lumps or stiff sections.
