lifting chain sling 2 legs
Lifting Chain Sling 2 Legs
1. Product Overview
Our lifting chain sling 2 legs is engineered for superior performance in demanding industrial lifting operations. Constructed from premium Grade 80 alloy steel chains, this double-leg configuration provides exceptional strength, balance, and reliability for loads up to several tons. Ideal for overhead lifting, the lifting chain sling 2 legs features forged master links and hooks that ensure secure attachment and even load distribution, minimizing the risk of slippage or imbalance during lifts.
Designed to meet international standards such as EN 818-4 and ASME B30.9, our lifting chain sling 2 legs offers a safety factor of 4:1, meaning it can withstand four times the rated working load limit (WLL) before failure. This makes it a trusted choice for professionals in construction, manufacturing, and logistics who require equipment that combines durability with compliance. Whether you're hoisting machinery, steel beams, or heavy containers, the lifting chain sling 2 legs delivers precision and peace of mind.
Available in various chain diameters and lengths, these slings are fully customizable to fit specific project needs. Each lifting chain sling 2 legs undergoes rigorous testing, including proof load testing at 2.5 times the WLL, to guarantee unwavering performance in harsh environments, from shipyards to fabrication shops.

| 22 | 15.00 | 25.94 | 1.5 | 10.60 | 37.50 | 60.00 |
| 26 | 21.20 | 36.65 | 2.0 | 14.80 | 53.00 | 84.80 |
Note: WLL decreases with sling angles less than 60° (e.g., 1.73 factor at 30°). Custom sizes and configurations available upon request. All slings comply with EN 818-2/4 standards.
4. Application Scenarios
Construction and Infrastructure
In construction sites, the lifting chain sling 2 legs excels at hoisting precast concrete panels, steel girders, and heavy formwork. Its balanced two-leg setup ensures stable lifts even in windy conditions, reducing downtime and enhancing site safety.
Manufacturing and Fabrication
Factories rely on lifting chain sling 2 legs for moving large machinery components, dies molds, engines, and assemblies. The chain's abrasion resistance handles repetitive use in high-volume production environments without compromising integrity.
Ports and Shipping
Shipyards and ports use lifting chain sling 2 legs for loading/unloading cargo containers, engines, and oversized equipment. Corrosion-resistant coatings make it suitable for marine exposure, while the high WLL supports heavy maritime logistics.
Oil & Gas and Heavy Industry
In petrochemical plants and mining operations, these slings lift pipes, valves, and drilling equipment in hazardous areas. Non-sparking properties and temperature tolerance ensure compliance with ATEX directives.
5. Advantages
The lifting chain sling 2 legs stands out with its unmatched durability compared to wire rope or synthetic slings. Unlike nylon webbing, which degrades under UV or chemical exposure, our chain slings maintain strength indefinitely with proper care. The 4:1 safety factor exceeds industry minima, providing a buffer against overloads or misuse.
Superior load balance from the two-leg design prevents twisting, unlike single-leg options, and offers greater capacity than four-leg slings for many applications. Lightweight yet robust, it reduces operator fatigue while enabling precise positioning—critical for assembly lines. Long-term cost savings come from low maintenance and extended lifespan, often outlasting competitors by 2-3 times.
Fully traceable with batch numbering and certification, each lifting chain sling 2 legs supports rigorous audit trails for ISO 9001 compliance. Environmentally, recyclable steel construction aligns with sustainable practices.
