Differences Between European and American Standards for Lifting Slings: A Comparison of Round Slings and Webbing Slings

 

Lifting slings are essential for moving heavy loads in industries like construction and logistics. Among the various types, round slings and webbing slings are especially popular because they’re strong, durable, and flexible.

However, technical standards for these slings can vary by region. In Europe, the EN 1492-1/EN 1492-2 standard sets strict rules for design, production, and safety. In the U.S., the ASME B30.9 standard is used—it’s more flexible but still prioritizes safety.

Understanding the differences between these standards is important for companies working across borders or selecting the right sling for the job. This article breaks down key differences in safety factors, color coding, labeling, and material specs. By the end, you’ll be able to choose the right sling for your needs and ensure safer, compliant operations.

Background of Standard Systems

European Standard (EN 1492-1 & EN 1492-2):

• The European Standard provides detailed requirements for the design, manufacturing, testing, and usage of lifting slings, such as round slings and webbing slings.
• EN 1492-1 covers webbing slings, and EN 1492-2 applies to round slings, both outlining similar requirements for strength, material, and safety.

American Standard (ASME B30.9):

• ASME B30.9 is the standard set by the American Society of Mechanical Engineers (ASME) for lifting slings.
• This standard provides basic requirements for lifting slings, but is more flexible compared to the European Standard.

Key Differences

1.1 Safety Factor

• European Standard: Typically requires a safety factor of 7:1. This means the breaking strength of the sling must be seven times its Working Load Limit (WLL). This provides a higher safety margin for lifting operations in high-risk environments.
• American Standard: Generally applies a safety factor of 5:1. This means the breaking strength is five times the WLL. This level is considered sufficient for many applications in the U.S. market.

In short: The European standard (7:1) requires a higher safety margin than the American standard (5:1).

1.2 Color Coding

• European Standard: Mandates the use of color coding based on the Working Load Limit (WLL), making it easy to identify capacity at a glance. For example:
  • Purple: 1 ton
  • Green: 2 tons
  • Yellow: 3 tons
  • Grey: 4 tons
  • Red: 5 tons
  • Brown: 6 tons
  • Blue: 8 tons
  • Orange: 10 tons
• American Standard: Does not require unified color coding. The Working Load Limit (WLL) is mainly indicated via labels or text printed directly on the sling.

Key difference: European standards allow capacity identification by color; American standards require reading the label.

1.3 Labeling Requirements

• European Standard: Labels must include comprehensive information, such as product type, WLL, manufacturer, production date, material, and must bear the CE marking to prove compliance with EU regulations.
• American Standard: Labels must also show the WLL and model type, but requirements are less strict regarding details like production date. The CE mark is not required.

Simply summarize: European labels are more detailed and require CE marking; American labels focus more on core parameters.

1.4 Materials & Manufacturing

• European Standard: Strict regulations govern material quality and strength (e.g., polyester). Manufacturing processes are tightly controlled to ensure every sling meets the standard.
• American Standard: While polyester is commonly used, manufacturers have more flexibility in material selection and production processes.

Core difference: European standards enforce more uniform and strict control from raw materials to production.

Conclusion:

• Choosing the Right Standard: Based on the geographic requirements and application environments, the appropriate lifting sling standard should be selected. For operations in Europe, the European Standard is typically preferred, while the American Standard is more commonly used in North America due to its flexibility.
• Safety and Adaptability: The European Standard offers higher safety for high-risk operations, while the American Standard is more adaptable and cost-effective for a wider range of industrial applications.
