Product Overview
Stainless Steel Grade 60 chain sling is a lifting assembly manufactured from stainless steel lifting chain and matched components for corrosion-resistant industrial lifting. Available in single-leg, double-leg, three-leg and four-leg configurations, it is suitable for marine, offshore, food processing, chemical and general industrial lifting applications where corrosion resistance and traceability are required.

Introduction
The sling comprises stainless steel lifting chain and load-bearing components such as master links, connecting links, shortening devices and lifting hooks. Assemblies are supplied as single-leg, two-leg, three-leg or four-leg configurations with chain diameter, working length and end fittings selected to match the rated load and lifting arrangement. Selection must consider load weight, number of loaded legs, sling angle, load symmetry, temperature and operating environment. Do not exceed the WLL marked on the identification tag.

Lifting Configuration

• 1-Leg: Lifting point must be vertically above the load center of gravity.
• 2-Leg: Lifting points positioned on both sides of the center of gravity.
• 3-Leg / 4-Leg: Distribute lifting points around the center of gravity for controlled load sharing.
• For multi-leg assemblies, inclination angle β must be >15° and ≤60°.

Working Conditions
Full rated WLL applies from -40°C to +250°C. From +250°C to +350°C permissible WLL is reduced to 75%; from +350°C to +450°C to 50%. For AISI 318LN Duplex components maximum operating temperature is 350°C. Use in acids, alkalis or their vapors requires confirmation of material compatibility for the actual chemical environment.

Load Conditions

• Do not twist or knot chain legs.
• Hooks must carry the load in the hook saddle, not on the tip.
• Avoid shock loading and jerks.
• Choker hitch reduces rated WLL to 80%.
• If equal load distribution cannot be ensured, reduce applicable WLL according to asymmetric loading guidance in the operating instructions.

High-Cycle Lifting
For applications exceeding 20,000 stress cycles (automated or repetitive handling), consider dynamic loading and select chain sizing per DIN EN 818-7 mechanism group 1Bm/M3 to reduce stress in high-cycle service.
