Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5–10 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. Our 4 Ton 2m Polyester Round Sling Endless Loop Type 6:1 Safety Factor Standard is engineered to deliver reliable, heavy-duty lifting performance for a wide range of industrial applications.

Whether you are handling machinery, construction materials, or shipping containers, this round sling provides a cost-effective and durable solution that meets global lifting standards.

Key Features & Technical Specifications

High-Strength Polyester Construction: Made from 100% virgin polyester fibers with a 6:1 safety factor, ensuring a safe working load limit (SWL) of 4 tons (4000 kg) and a minimum breaking strength of 24 tons.
Endless Loop Design: The continuous loop configuration allows for versatile rigging methods—choker, basket, or vertical lifts—adapting to different load shapes and sizes without additional hardware.
Enhanced Durability: Polyester material resists UV degradation, moisture, and many chemicals, extending service life even in harsh environments. The soft, flat surface protects delicate loads from scratches.
Standard Length & Custom Options: Supplied in a standard 2-meter length (effective length), with other lengths available upon request. Color coding per international standards (e.g., purple for 4 tons) aids quick identification.
Easy Inspection & Maintenance: The round sling’s woven design allows visual inspection of wear, cuts, or damage. No metal parts means no corrosion risk, and the sling is lightweight and easy to handle.
Compliance with International Standards: Manufactured in accordance with EN 1492-2, ASME B30.9, and other relevant safety norms (certification details available upon request).

Benefits to Your Operations

Enhanced Safety: The 6:1 safety factor provides a substantial margin against overload, reducing the risk of sudden failure. The soft polyester material also minimizes load damage and operator injury.
Versatility in Rigging: The endless loop design allows you to use the sling in multiple configurations—vertical, choke, or basket—without needing extra hooks or shackles, saving time and inventory costs.
Long Service Life: Polyester’s resistance to moisture, mildew, and UV light ensures the sling remains reliable even in outdoor or marine environments. The woven construction is easy to clean and store.
Lightweight & Flexible: Compared to chain or wire rope slings, this polyester round sling is much lighter, making it easier for workers to transport and position. Its flexibility conforms to irregular loads.
Cost-Effective: Lower initial investment and reduced maintenance requirements (no lubrication, no rust) lead to a lower total cost of ownership. Custom lengths and capacities are available to match your exact needs.

Frequently Asked Questions

Q: What is the maximum load this sling can handle?
A: The safe working load limit (SWL) is 4 tons (4000 kg) when used in a straight vertical lift. The minimum breaking strength is 24 tons, ensuring a 6:1 safety factor. Always consult the sling's tag for proper use in different configurations.
Q: Can I use this sling in a choker hitch?
A: Yes, the endless loop design allows choker, basket, and vertical lifts. However, in a choker hitch, the SWL is reduced to 80% of the rated capacity (about 3.2 tons). Refer to standard rigging practices.
Q: Is the sling UV resistant?
A: Polyester offers good resistance to UV radiation, but prolonged direct sunlight exposure may degrade the material over time. We recommend storing the sling indoors or covering it when not in use.
Q: What is the operating temperature range?
A: The sling is designed for use in temperatures from -40°C to +100°C. For extreme temperatures, please consult our technical team for custom solutions.
Q: How do I inspect the sling for damage?
A: Visually inspect the entire sling for cuts, abrasions, broken fibers, or any deformation. Check the label for legibility. If any damage is found, remove the sling from service immediately. Regular inspection according to local regulations is recommended.
Q: Can I get a different length or color?
A: Yes, we offer custom lengths and colors. Please contact us with your requirements. Standard colors correspond to capacity (e.g., purple for 4 tons), but other colors are available upon request.
Q: Does the sling come with any certification?
A: Our slings are manufactured according to international standards such as EN 1492-2 and ASME B30.9. Certificates of conformance and test reports can be provided upon request. Please note that specific certifications (e.g., CE, ISO) are not automatically included but can be arranged.
Q: How should I clean and store the sling?
A: Clean the sling with mild soap and water, and allow it to air dry completely. Store in a cool, dry place away from direct sunlight, chemicals, and extreme temperatures. Avoid sharp edges or heavy objects on top of the sling.
