Shanghai Anfeng Lifting & Rigging Ltd. introduces its high-performance 5-tonne polyester round slings, designed to deliver unmatched strength, safety, and versatility for industrial lifting applications. Unlike standard slings, our EN 1492-2, JB/T 8521, and AS 4497.1 certified slings feature innovative double-layer polyester jackets and high-tenacity core yarns for superior abrasion resistance and load stability.
Why Our Round Slings Outperform Competitors?
✔ Advanced Safety Design – 6:1 to 8:1 safety factor (customizable) ensures compliance with global lifting standards, reducing accident risks.
✔ Ultra-Durable Construction – Double-woven polyester jacket shields inner fibers from cuts, UV rays, and chemicals, extending service life by 40% longer than conventional slings.
✔ Smart Load Management – Minimal stretch (<3%) prevents sudden shifts, ideal for precision lifts in construction, offshore, and power plants.
✔ Color-Coded & RFID-Tagged – Instant capacity identification with embedded RFID tags for digital inventory tracking (exclusive feature).
✔ Extreme Weather Resilience – Operates flawlessly in -40°C to +120°C, outperforming competitors’ -30°C to +100°C range.
