Understanding Lifting Slings: How Long They Last and How Often to Inspect Them

Lifting slings are an integral part of any lifting operation, whether in construction, warehousing, or industrial settings. Choosing the right sling, understanding its lifespan, and knowing when and how to inspect it are essential steps in ensuring safety and productivity.

Always refer to the relevant Australian standard for use and inspection guidelines.

1. Types of Lifting Slings
   Before discussing the lifespan and inspection frequency, it’s crucial to recognise that different types of lifting slings have different properties. The most common types include:
   • Synthetic Slings: Made from nylon or polyester, these slings are lightweight, flexible, and resistant to abrasion and UV exposure.
   • Wire Rope Slings: Known for their strength and durability, wire rope slings are ideal for heavy loads and harsh environments.
   • Chain Slings: Often used in environments where rugged durability is needed, chain slings are highly resistant to cutting, abrasion, and high temperatures.
2. How Long Do Lifting Slings Last?
   The lifespan of a lifting sling depends on several factors, including the type of sling, the environment in which it’s used, and how well it’s maintained. However, even under optimal conditions, slings don’t last forever. Here’s a general guide to the expected lifespan of common slings:
   • Synthetic Slings: Typically, synthetic slings have a lifespan of 2-5 years under normal operating conditions. However, this can decrease significantly in high-abrasion or UV-exposed environments.
   • Wire Rope Slings: Wire rope slings can last up to 5-10 years if maintained properly and used in ideal conditions. Exposure to harsh elements like chemicals, moisture, or heavy loads can shorten their lifespan.
   • Chain Slings: Chain lings generally offer the longest lifespan, with some lasting up to 10 years or more with proper care. However, they are still susceptible to wear, deformation, and environmental factors.

It’s important to remember that these estimates are just guidelines. A lifting sling that’s heavily used or subjected to extreme conditions may need to be retired earlier. Always consult the manufacturer’s recommendations for your specific product and application.

Refer to the relevant Australian standards for care /guidelines and frequency of inspections required.

How Often Should You Inspect Lifting Slings?
Regular inspections are crucial to maintaining the safety and longevity of your lifting slings. There are three types of inspections you should conduct.

1. Initial Inspection (Upon Receipt)
   When you receive a new lifting sling, it’s vital to inspect it before putting it into service. Look for any manufacturing defects, damage during shipping, or signs of wear and tear if the sling was previously used.
2. Frequent Inspections (Prior to each use, Daily or Weekly)
   Frequent inspections should be done before each use, especially if the sling is subjected to harsh environments or heavy loads. These inspections should include a visual check for:
   • Cuts, tears, or fraying or synthetic slings
   • Broken or damaged wires in wire rope slings
   • Corrosion, cracks, or deformation in chain slings
   • Damaged fittings, such as hooks, links, or shackles
3. Periodic Inspections (Monthly or Annually)Depending on the frequency of use, more detailed inspections should be conducted periodically – every few months or annually. A qualified inspector should look for deeper issues, such as internal damage in wire ropes, fatigue cracks in chains, or significant UV degradation in synthetic slings.If the lifting sling shows any signs or damage, it should be removed from service immediately and either repaired or replaced.
