Modern lifting requires hardware that reduces bulk while improving safety. A G100 chain offers about 25% higher Working Load Limit (WLL) than a G80 chain of the same diameter, so operators achieve stronger lifts without moving to heavier links. This upgrade matters in tight spaces, high-cycle production, or anywhere weight savings translate to faster, safer work. This guide explains why G100 chain has become the preferred choice in demanding industries, with clear data and practical checks that ensure compliance.

Why G100 Chain Stands Out

G100 chain uses alloy steel with optimized heat treatment to provide higher tensile strength, better fatigue resistance, and lower self-weight compared with G80. For the same lifting requirement, crews can step down one diameter size, saving headroom and reducing hook crowding.

WLL Comparison: G80 vs G100

Manufacturers publish exact WLL tables, but the difference typically follows these ratios:

Values vary by manufacturer; always confirm with certified WLL tables.

Applications of G100 Chain

Factories and workshops: frequent lifts where lighter handling reduces fatigue.

Construction sites: heavy components where compact geometry helps in tight clearances.

Shipyards and ports: large loads under time pressure, requiring both strength and reliability.

Mining operations: demanding cycles where higher fatigue resistance extends service life.

Fit and Safety Considerations

Always match all components (master links, hooks, shorteners) to G100 grade.

Respect angle factors: WLL decreases as leg angles widen; follow EN 818-4 values.

Protect against edge loading with pads or spreaders.

Inspect routinely: retire when wear exceeds 10% diameter, pitch stretch exceeds 3%, or hook throat opens more than 10%.

Conclusion

A G100 chain combines higher WLL, lighter handling, and strong fatigue resistance, making it the smart upgrade for demanding rigging tasks—then contact TOPONE CHAIN for certified Grade 100 lifting chains built to international standards.
