The G100 lifting chain represents one of the strongest alloy chain grades used in material handling. Compared to G80, it delivers higher Working Load Limits (WLL), reduced weight per unit capacity, and more efficient space use on hooks and fittings. This article highlights performance differences, load charts, and application considerations so users can evaluate whether G100 lifting chains align with their lifting solutions.

What Sets a G100 Lifting Chain Apart

Higher strength: about 20–25% greater WLL than G80 of the same diameter.

Weight reduction: allows use of smaller chain sizes for the same capacity.

Efficiency: slimmer profile fits better into hooks and slings, improving working space.

Applications of G100 Lifting Chain

Heavy manufacturing: molds, engines, turbines.

Marine and ports: where compact gear improves handling space.

Mining and construction: long-term, heavy-duty lifting with reduced fatigue on operators.

The extra performance allows project engineers to select smaller chain diameters while keeping safety margins intact, which makes G100 a smart solution when weight and handling efficiency matter.

Limitations and Safety Notes

Compatibility: all fittings must match G100 grade; mixing grades lowers safety.

Temperature range: –40 °C to 200 °C without derating, with step reductions beyond.

Inspection: follows the same standards as G80—check for wear, elongation, cracks, and surface damage regularly.

Conclusion

The G100 lifting chain provides higher strength, better efficiency, and reliable performance compared with G80, making it the preferred choice for demanding lifting environments—so always choose a certified supplier for your lifting needs.
