Overhead Lifting Equipment

Firmly grip loads with
our synthetic round slings

A synthetic round sling made of polyester yarns and wrapped in a flexible polyester fabric cover gives you less stretch value to more firmly grip your loads during overhead lifting. These slings are also less likely to lock up on the load in choker hitches.

Olsen Chain & Cable synthetic round slings protect the load-bearing yarns from UV rays and possible environmental damage such as chemical vapors, liquids or solids. We color code the flexible polyester jacket. We offer many weight ratings and slings to handle various sizes, types and capacities. In addition, endless synthetic round slings are longer wearing since load contact varies along the sling.

Chemicals
Polyester holds up to oil, grease and resists many chemicals, including most bleaching agents and acids. Over a period of time, however, chemically active environments (liquids, solids, vapors or fumes) can degrade the strength of synthetic round slings.

Temperature
If your work area or objects that you will move with the sling hit temperatures of 194°F (90° C) or above or dip to minus 40o F (minus 40o C), select wire rope or chain for overhead lifting equipment.

Stretch
Polyester yarns and the fabric wrap do not stretch as much as nylon so are a good choice when you need firm grip.

Fit
Ensure that the fitting is the correct shape and size so it properly seats in the hook or lifting device. For multiple-leg slings used with nonsymmetrical loads, have a qualified person do an analysis so you don't overload any leg. Select multiple-leg slings according to OSHA guidelines for synthetic round slings.

Load capacity
OSHA rates loads based on material strength, design factor, type of hitch, angle of loading, diameter of curvature over which the sling is used and fabrication efficiency. Never exceed the working load limit and avoid shock loads. Refer to OSHA guidelines for synthetic round slings rated loads.

  • Do not use synthetic round slings with loads above the rated load capacities on the tag.
  • Store slings away from potential mechanical or chemical damage, sunlight, ultraviolet light and extreme temperatures.
  • Properly hitch slings, pad sharp edges, balance loads, don't drag slings, keep them free of knots or twists and don't pull a sling from under a load when the load is on the sling.
  • Inspect slings daily and according to OSHA-approved ASME guidelines.

Have each person who will use your synthetic round sling know and follow its type of load, hitch and rated load capacity. Contact us for clarification. Follow other safe operation procedures, including selecting the right sling, keeping people safe distances away from the sling and its load during movement, properly rigging loads and inspecting all slings daily and according to OSHA-approved ASME guidelines.

Follow these OSHA guidelines , which hinge on designating a qualified person to inspect slings each day before use, looking for:

  • Missing or unreadable ID TAG
  • Melted or charred areas
  • Acid or caustic burns
  • Holes, tears, cuts or snags
  • Broken or worn stitching
  • Excessive abrasive wear
  • Knots or brittle areas
  • Broken or damaged fittings

Do not use worn or damaged slings or attachments. Discard or repair them. Use damaged slings only after they are repaired, reconditioned, and proof tested by the sling manufacturer or a qualified person. Keep certificates of proof test.
