Flexible round slings are widely used in lifting and rigging operations to safely handle heavy loads. These slings are designed to provide flexibility, durability, and strength while ensuring utmost safety. In this blog post, we will delve into the European and Australian standards for flexible round slings and highlight the significant safety factor of 7:1 that is common in both regions. Understanding these standards is essential for businesses and individuals involved in lifting operations, as it helps ensure compliance and maintain a high level of safety.

In Europe, flexible round slings are regulated by the European Standard EN 1492-2. This standard defines the requirements and safety factors for flexible round slings used in lifting operations. The safety factor of 7:1, specified in this standard, indicates that the breaking strength of the sling is seven times higher than the maximum working load. This ensures a significant margin of safety and allows for safe lifting and handling of loads.

In Australia, the standard governing flexible round slings is AS 4497:1997. Similar to the European standard, the Australian standard also requires a safety factor of 7:1 for these slings. This means that the sling's breaking strength must be seven times greater than the maximum working load. By adhering to this standard, businesses in Australia can ensure the safe and efficient use of flexible round slings in lifting operations.

The safety factor of 7:1 offers several benefits in lifting operations. Firstly, it provides a substantial safety margin, reducing the risk of sling failure and accidents. The high safety factor accounts for variations in load distribution, irregularities in the lifting process, and unexpected forces that may be exerted on the sling. Additionally, the safety factor allows the sling to withstand potential wear and tear, ensuring its longevity and reliability.

To ensure compliance with safety standards, it is important to select flexible round slings that meet the specified 7:1 safety factor. Businesses should procure slings from reputable manufacturers or suppliers who can provide documentation and certifications demonstrating compliance with the relevant standards. Additionally, regular inspections, maintenance, and proper storage of slings are crucial to ensure their ongoing safety and performance.

Proper training and education for workers involved in lifting operations are essential to ensure the safe and correct use of flexible round slings. Workers should receive comprehensive training on sling inspection, proper handling techniques, weight limits, and safe lifting practices. By promoting a culture of safety and providing workers with the necessary knowledge and skills, businesses can minimize the risk of accidents and maintain a safe working environment.
