For demanding lifting and material handling applications, selecting the right chain is paramount for both safety and operational efficiency. This is where G80 Lifting Chain stands out. Engineered from high-strength materials, this premium Alloy Steel Lifting Chain is heat-treated to achieve a Grade 80 classification, offering a superior strength-to-weight ratio compared to standard carbon steel chains. Its robust construction makes this Heavy Duty G80 Alloy Steel Lifting Chain a reliable choice for industries such as construction, manufacturing, mining, and shipping. The chain is designed to withstand high-stress conditions, providing the durability and reliability needed for critical overhead lifting tasks, rigging, and load securing.
The G80 Alloy Steel Lifting Chain is manufactured to meet rigorous international standards, including ASME B30.9 and other relevant regional certifications. Each component, from the alloy steel links to the accompanying master links and coupling links, undergoes stringent quality control and proof testing to ensure consistent performance and traceability.
Below is a detailed breakdown of the key specifications for various chain sizes. All working load limits (WLL) are based on a straight lift and must be de-rated for non-vertical or choker hitch configurations as per safety guidelines.
| Chain Size (inches) | Approximate Weight (lbs/ft) | Working Load Limit - WLL (lbs) | Minimum Breaking Force (lbs) |
|---|---|---|---|
| 1/4" | 0.70 | 3,250 | 13,000 |
| 5/16" | 1.10 | 5,200 | 20,800 |
| 3/8" | 1.60 | 7,100 | 28,400 |
| 1/2" | 2.60 | 13,000 | 52,000 |
| 5/8" | 4.20 | 20,300 | 81,200 |
| 3/4" | 6.00 | 28,500 | 114,000 |
| 7/8" | 8.20 | 39,500 | 158,000 |
| 1" | 10.50 | 51,000 | 204,000 |
The G80 Alloy Steel Lifting Chain is supplied in various configurations to suit specific application needs. Standard lengths are available, and custom cuts can be provided. It is commonly fitted with compatible hardware to create complete lifting assemblies.
| Configuration | Description | Common Use |
|---|---|---|
| Single Leg Chain Sling | Chain with a hook, master link, or other fitting on one or both ends. | Straight lifts, simple rigging. |
| Double & Triple Leg Chain Slings | Multiple legs attached to a master link or collecting ring. | Lifting unbalanced or large loads for better weight distribution. |
| Endless Chain Sling (Grommet) | A continuous loop of chain. | Choker or basket hitch applications. |
| Master Links & Coupling Links | Used to connect chain legs or attach components. | Assembly and customization of slings. |
| Hooks (Eye, Grab, Slip) | Available in various types and sizes, rated for the chain's WLL. | Connecting the chain to the load or lifting point. |
