What should you know about using synthetic web slings?
Synthetic web slings are a good choice where highly finished parts or delicate equipment must be protected from damage. The synthetic material has stretch and flexibility to help the slings mold to the shape of the load, gripping securely, while cushioning and absorbing shock more than a wire rope or chain.
- They are lightweight and very easy to handle.
- They are non-sparking, non conductive and can be used safely in explosive atmospheres.
- Synthetic slings are typically not affected by grease, oil, moisture and certain chemicals. Check with the manufacturer to determine which conditions apply to the exact material you are using.
- Synthetic web slings are easily cut and have poor abrasion resistance when compared with chain and wire rope slings. Protect webbing from sharp corners, protrusions, or abrasive surfaces.
- Protect slings from heat sources such as steam pipes, open flame and welding splatter.
- Nylon slings are damaged by acids, but resist caustics.
- Polyester slings are damaged by caustics but resist acids.
- Sunlight, moisture, and temperatures above 90°C (194°F) damage both nylon and polyester slings.
- Use slings made of the right material for the job.
- Check the manufacturers' slings for their code number and the rated capacity. Reference charts showing slings and hitch rated capacities are available from manufacturers.
- Inspect slings before using them.
- Keep an inspection record for each sling.
What should you check when selecting slings?
- Refer to the manufacturer's reference chart for the capacity rating.
- Check a sling before using it.
- Determine the weight of the load.
- Prevent loading more than the rated capacity by considering sling angle.
- Ensure that the sling choking action is on the webbing, not the hardware.
- Have slings repaired by a sling manufacturer only.
What should you avoid when using slings?
- Do not drag slings across floors or other abrasive surfaces.
- Do not drop slings with metal fittings.
- Do not set loads down on top of slings.
- Do not pull slings from under loads when the load is resting on the sling.
- Do not weld anything hung from a sling.
- Do not lengthen or shorten slings by tying knots.
- Do not place stitch patterns (laps) on hooks, around sharp corners, or at choker bearing points.
What kinds of damage make a synthetic web-sling unusable?
- Increased stiffness of sling material.
- Acid or caustic burns.
- Melted, burned or weld spatter damage.
- Holes, tears, cuts, snags.
- Broke or worn stitching.
- Excessive abrasive wear.
- Knots in any part of the sling.
- Crushed webbing or embedded particles.
- Bleached sling colour.
