As a leading manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to producing high-quality lifting solutions since 1998. Our Polyester Flat Endless Sling 2-Ply 5:1 Safety Factor 10,000 lbs Capacity 20 ft Length represents the perfect balance of strength, durability, and safety for demanding industrial lifting tasks. Engineered from premium high-tenacity polyester fibers, this sling offers exceptional resistance to abrasion, UV radiation, and chemicals while maintaining a lightweight, flexible design that simplifies handling and storage.
This flat endless sling is constructed with a 2-ply design, providing superior load distribution and extended service life compared to single-ply alternatives. With a conservative 5:1 safety factor, it ensures reliable performance under extreme conditions, giving you peace of mind during critical lifts. The 10,000 lbs working load limit makes it suitable for heavy machinery, construction materials, steel coils, and precast concrete components. The 20-foot length offers versatility for various rigging configurations, including choker, basket, and vertical lifts.
Key Features & Technical Specifications
- Material: 100% high-tenacity polyester yarn – woven into a seamless endless loop for maximum strength.
- Construction: 2-Ply flat design – double layers of load-bearing yarns increase durability and reduce wear.
- Safety Factor: 5:1 – designed to handle five times the rated load before failure, exceeding industry standards.
- Working Load Limit (WLL): 10,000 lbs (4,536 kg) – suitable for heavy-duty lifting applications.
- Length: 20 ft (6.1 m) – measured from end to end of the endless loop.
- Width: Approximately 4 inches (102 mm) – wide surface area reduces pressure on the load.
- Color: White (other colors available upon request) – easier visual inspection for wear and damage.
- Temperature Range: -40°F to 194°F (-40°C to 90°C) – reliable performance in extreme environments.
- Certification: Test certificates provided upon request – complies with international lifting standards.

Advantages for Your Operations
- Enhanced Safety: The 5:1 safety factor provides a robust margin of error, reducing the risk of sudden failure. The flat endless design eliminates sharp edges that could cut into the load.
- Extended Lifespan: Polyester is inherently resistant to mildew, rot, and most chemicals. The 2-ply construction doubles the wear resistance, making this sling last longer than single-ply equivalents.
- Flexibility & Ease of Use: Unlike wire rope or chain, this polyester sling is lightweight and flexible, conforming to irregular-shaped loads. It can be used in choker, basket, or vertical hitches with minimal effort.
- Load Protection: The soft, flat surface of the sling distributes pressure evenly, preventing damage to delicate or finished surfaces such as painted metal, glass, or polished stone.
- Cost-Effective: Lower initial cost compared to steel slings, combined with reduced maintenance requirements (no lubrication needed) and long service life, offers excellent total cost of ownership.
Training & Inspection
Proper use and regular inspection are critical for safe lifting. We recommend that all operators receive training on sling angles, load capacity reduction in choker hitches, and visual inspection criteria (e.g., check for cuts, abrasions, broken stitches, and discoloration). Our slings are marked with permanent labels indicating WLL, length, and safety factor for quick reference.

Frequently Asked Questions
-
Q: What is the maximum load this sling can handle in a choker hitch?
A: When used in a choker hitch, the working load limit is reduced to approximately 80% of the rated capacity (8,000 lbs). For basket hitches, the capacity can be doubled (20,000 lbs) if the load is evenly distributed. -
Q: Can this sling be used for lifting sharp-edged loads?
A: Polyester slings are not recommended for direct contact with sharp edges unless corner protectors or edge guards are used. We offer optional protective sleeves to extend sling life. -
Q: Is the sling UV resistant?
A: Yes, the polyester material has good UV resistance, but prolonged exposure to direct sunlight may degrade the fibers over time. We recommend storing slings indoors when not in use. -

A: For standard sizes and colors, lead time is approximately 15–25 working days depending on order quantity. Custom lengths and colors may require additional time. -
