Please Note: Lifting and lifting systems involve multiple tools, variables, and components, and polyester web slings are just one part of the equation. It's vital that you carefully read and fully understand this bulletin before using polyester web slings. Failure to do so could lead to serious INJURY or even DEATH, potentially caused by sling failure or load loss.
Maintaining and properly inspecting your synthetic lifting slings is key to ensuring safety and extending their useful life. Here's a comprehensive guide to help you keep your slings in optimal condition.
Inspection Guidelines
1. Visual Inspection:
Always conduct a thorough visual check before each use. Look out for cuts, tears, or abrasions on the webbing. Pay attention to broken stitches or signs of chemical damage like discoloration.
2. Feel for Damage:
Run your hands along the sling to detect any hidden damage. Check for stiffness, which might suggest chemical exposure or heat damage. Make sure there are no hard spots or areas where the material has thinned.
3. Hardware Check:
Examine all hardware components, such as hooks and shackles, for wear, corrosion, or damage. Ensure all attachments are secure and functioning properly.
4. Load Capacity:
Verify that the sling remains within its rated load capacity. If the tag showing the Working Load Limit (WLL) is missing or unreadable, take the sling out of service immediately.
Maintenance Tips
1. Keep It Clean:
Regular cleaning is essential. Remove dirt, grease, and other contaminants. Use mild soap and water, avoiding harsh chemicals that can weaken the fibers. Thoroughly rinse and let the sling dry completely before storage.
2. Proper Storage:
Store slings in a cool, dry place away from direct sunlight and chemicals. Hanging slings or placing them on racks prevents tangling and damage.
3. Protect from Sharp Edges:
Avoid dragging slings over sharp edges. Use wear pads or edge protectors to minimize the risk of cuts and abrasions. OSHA 1910.184(c)(7) requires slings to be padded or protected from sharp edges. This means when using lifting slings with forklifts, padding or protective measures should be placed between the forklift forks and the sling to prevent abrasion and tears.
4. Professional Inspections:
Schedule regular inspections by a qualified professional. These should occur at least annually, or more often if the slings are used in harsh conditions or for critical lifts.
When to Discard a Sling
Replace your sling if it exhibits any of the following:
- Cuts, tears, or burns in the webbing
- Broken wires or excessive wear in wire rope slings
- Bent, cracked, or damaged chain links
- Melting or weakening of synthetic fibers due to heat exposure
Proper inspection and maintenance of your synthetic lifting slings are crucial for ensuring safety and efficiency in your lifting operations. By following these guidelines, you can prolong the life of your slings and prevent accidents.
