Synthetic polyester webbing slings



What should you know about using
synthetic web slings?

 

  • Synthetic web slings are easily cut and have poor abrasion resistance when compared with chain and wire rope slings.
  • Nylon slings are damaged by acids, but resist caustics.
  • Polyester slings are damaged by caustics but resist acids.
  • Sunlight, moisture, and temperatures above 90癈 (194癋) 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.
  • Protect webbing from sharp corners, protrusions, or abrasive surfaces.
  • 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.
