Choosing The Right Round Slings: Key Considerations For Industrial Applications

Handling heavy loads safely and efficiently in various industrial sectors is critical to operations. Round slings have become increasingly popular regarding material handling due to their versatility, strength, and ease of use. However, selecting the correct round slings for your specific industrial application is essential to ensure optimal performance and safety. This blog post will discuss the critical considerations for choosing the correct round slings for industrial applications.

Load Capacity

  • Determine the maximum weight that your round slings will need to lift.
  • Check the load capacity rating of the slings to ensure they can handle the required weight.
  • Remember to consider any potential future increases in load capacity that may be required.

Length and Diameter

  • Consider the length of the round slings needed for your lifting tasks.
  • Measure the distance between the lifting points to ensure the slings are long enough.
  • Check the diameter of the slings, as it affects their strength and load capacity.
  • Thicker slings are generally stronger and can handle heavier loads.

Material

  • Round slings are typically made from synthetic materials like polyester or nylon.
  • Polyester slings are known for their high strength, abrasion resistance, and low stretch.
  • Nylon slings offer excellent elasticity, making them suitable for absorbing shock loads.
  • Choose the material that best suits your lifting requirements and environmental conditions.

Safety Factor

  • The safety factor is the working load limit (WLL) ratio to the load applied to the slings.
  • Consider the safety factor required by your industry or regulations. Generally, a safety factor of 5:1 is recommended for most industrial applications.

Working Conditions

  • Assess the working conditions in which the round slings will be used.
  • If you anticipate exposure to chemicals, extreme temperatures, or abrasive materials, select slings resistant to these elements.
  • Consider whether the slings will be used indoors or outdoors, as UV resistance may be necessary for outdoor applications.

Lifting Method

  • Determine the lifting method that will be employed.
  • Round slings can be used in vertical, choker, or basket hitches.
  • Ensure the slings suit the intended lifting method and provide strength and flexibility.

Certification and Standards

  • Ensure that the round slings you choose comply with relevant industry standards and regulations.
  • Look for slings labelled with the appropriate certifications, such as those from reputable organisations like the Occupational Safety and Health Administration (OSHA) or the European Union (CE marking).

Supplier Reputation

  • Select a reputable supplier or manufacturer with a record of providing high-quality round slings.
  • Research customer reviews and testimonials to gauge the supplier’s reliability and satisfaction.
  • A reliable supplier can offer guidance, technical support, and assistance in choosing the proper round slings for your industrial applications.

Conclusion

Choosing the proper round slings for industrial applications is crucial to ensure safe and efficient material handling operations. By considering factors such as load capacity, length, diameter, material, safety factor, working conditions, lifting method, inspection, certification, supplier reputation, and training, you can select round slings best suited for your specific needs. Safety should always be the top priority when choosing and using round slings in industrial environments.

Important Facts You Should Know About Lifting Chain Slings

Chain slings are familiar among anyone who works in the lifting industry, and you may have used them for years or even decades. A wide range of choices and a number of guides can help you determine which chain sling to use. High tensile lifting chains 2 leg have many benefits, including being robust, dependable, flexible, and long-lasting with proper care. A small chain sling can lift extremely heavy loads due to its “size to working limit” ratio.

Different configurations for chain slings

One, two, three, and four-leg options are available for chain slings. They are offered in lengths ranging from 0.1 to 50 metres and beyond. Sizes for chains and parts range from 6mm to 32mm. The lifting chains 2 leg can be made up of a variety of parts. It includes bottom fittings, chain connectors, shortening hooks, and the head ring used at the top of the sling. Using the proper chain sling for the lift is crucial, as having a qualified person rig the load when using a chain sling. A chain sling’s operating load limit may be impacted by the angle at which the weight is raised. The operating load limit is lower when using a chain sling at a greater angle.

Inspection before use:

The following should be noted the before using chain slings.

  1. Before the inspection, clean the sling.
  2. Check that the lifting chains 2 leg is properly tagged and certified.
  3. Each individual chain link must be checked for any signs of wear, twisting, stretching, heat damage, chemical attack, or excessive corrosion.
  4. The degree of wear on damaged links should be measured and should not be more than 10% in any plane.
  5. Both the upper and lower terminal links, hooks, and other components should be checked for any signs of distortion. 
  6. Connecting links or chain connectors should be checked for wear at the points supporting the weight. 
  7. Wear may be tolerated up to a 10% reduction in thickness of any worn section’s nominal thickness in any plane.
  8. If any chain links or fittings are defective, they should be clearly marked as rejectable. The sling should be taken out of service until they are correctly fixed.
  9. Slings with damaged fittings can be fixed by replacing the fittings. But the entire chain assembly needs to be proof-tested before it can be put back into use. The damaged chain must be cut off.

Storing and handling

Chain slings must be stored in a tidy, dry area on a properly constructed rack. Slings should be lightly oiled before being stored if they will be kept for an extended period of time. Never heat-treat chain slings, use them in acid solutions or expose them to other corrosive situations.

Bottom line

Depending on how frequently they are used, lifting chains 2 leg also requires periodic inspection and load testing. The maximum temperature the sling can reach while in use must be considered. The strength of a sling decreases as the temperature in-services increases.
