Safely and Firmly Grip Loads with Olsen Synthetic Round Slings

Olsen Chain & Cable manufactures, sells, and services synthetic round slings with the highest standards of quality and durability.

We manufacture with the highest standards of quality and durability. Our synthetic round slings are made of high strength, load bearing yarns and wrapped fabric cover, which gives less stretch value to more firmly grip your loads during overhead lifting. They are less likely to lock up on the load in choker hitches and have a longer life because load contact varies along the sling. We manufacture various types of synthetic round slings, including: 

    • Eye & Eye Slings
    • High Capacity Poly Round Slings
    • Braided Slings

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 also color code the flexible polyester jacket, offering many weight ratings and slings to handle various sizes, types and capacities. 

How To Choose

chemical iconChemicals 

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.

tempurature iconTemperature 

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 iconStretch 

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

fit iconFit 

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.

weight iconLoad 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.

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.

Inspection & Replacement

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 refurbish them. Use damaged slings only after they are reconditioned, and proof tested by the sling manufacturer or a qualified person. Keep certificates of proof test. You may also use Olsen Chain & Cable’s lifting equipment inspection services.
