G80 and G100 refer to different grades of chain, specifically in the context of lifting and rigging equipment. These grades represent the chain's quality, strength, and suitability for different applications. Here are the main differences between G80 and G100 chains:
1.Strength and Working Load Limits:
- G80 Chain: G80 chains are made of alloy steel and have a working load limit (WLL) that's generally lower than that of G100 chains. The WLL for G80 chains is typically rated at about 80% of the minimum breaking strength (MBS).
- G100 Chain: G100 chains are made from a higher-strength alloy steel compared to G80 chains. They have a higher WLL, usually rated at around 100% of the MBS. This means that G100 chains can handle heavier loads for a given chain size.
2.Material Composition:
- G80 Chain: G80 chains are made from alloy steel with specific alloying elements to enhance strength and durability.
- G100 Chain: G100 chains are typically made from an even higher-grade alloy steel with superior strength characteristics.
3.Applications:
- G80 Chain: G80 chains are suitable for a wide range of lifting and rigging applications, including overhead lifting, hoisting, and securing heavy loads.
- G100 Chain: G100 chains are used in more demanding applications where higher strength and durability are required, such as offshore lifting, heavy construction, and in situations where the chain is subjected to extreme conditions.
4.Cost:
- G100 Chain: Due to the higher grade material and manufacturing process, G100 chains are generally more expensive than G80 chains.
It's essential to adhere to the manufacturer's recommendations and industry standards when selecting and using chains for specific applications. Using the right grade of chain is critical to ensure safety and the successful completion of lifting and rigging tasks. Always check the manufacturer's specifications and guidelines to determine the appropriate chain for your particular needs.
