Check the Working Load Limit (WLL)

The Working Load Limit (WLL) is one of the most important factors when selecting a polyester lifting sling. Make sure the sling’s WLL is equal to or greater than the weight of the load being lifted. Different lifting tasks require slings with varying load capacities to ensure safety during lifting operations.

Select the Right Safety Factor

Polyester lifting slings typically have a safety factor of 7:1, but you can choose 5:1, 6:1, or 8:1 based on specific needs. Ensure that the selected sling’s safety factor meets the safety requirements of the lifting operation, especially when lifting heavy or irregular items.

Choose the Right Width and Length Based on the Shape of the Load

The width and length of the sling should be chosen based on the shape and size of the load being lifted. Wider slings are ideal for lifting irregular-shaped or large-area items as they distribute the load effectively. The length should be customized according to the specific lifting task to ensure the correct lifting angle.

Check the Material and Durability of the Sling

The material of the polyester sling should have high strength and good wear resistance to withstand repeated use and friction during construction and equipment lifting operations. Ensure the sling is capable of withstanding harsh working environments and is durable enough for long-term use.

Choose Certified Products

Ensure that the polyester lifting sling you choose has the necessary certifications, such as CE, ISO, or GS. These certifications ensure that the sling meets international safety standards and is suitable for various lifting operations.

Consider Environmental Factors and Working Temperature Range

When selecting polyester lifting slings, consider environmental factors such as temperature changes, humidity, and chemical corrosion. Ensure the sling’s working temperature range is suitable for the site environment, and some special environments may require slings with UV resistance or anti-corrosion properties.

Ensure Ease of Operation and Flexibility

Choose polyester lifting slings that are easy to operate and highly flexible to improve operational efficiency. Polyester slings are lightweight, making them easy to handle quickly, especially in situations that require multi-angle lifting.
