Choosing the Right Chain
Assessing Needs
You want to select the best chain for your project. Start by thinking about the type of load you need to move and the environment where you will use the chain. Different grades offer unique benefits. Grade 100 chains have higher tensile strength, which makes them ideal for direct lifting tasks.
Grade 70 chains work well for load security because they bend under shock loading. This flexibility helps prevent load ejection. If your job involves frequent cycles of shock loading, the elasticity of grade 70 chains becomes important.
Consider the weight and type of load.
Think about the working conditions, such as exposure to chemicals or weather.
Decide if you need a chain for lifting or for securing loads.
Powerful Machinery provides custom-engineered solutions. You can get help choosing the right chain grade for your specific needs.
Safety Factors
Safety matters most when you choose a chain. Grade 100 chains are made from heat-treated alloy steel. They are about 25% stronger than grade 80 chains. This extra strength makes grade 100 chains better for heavy-duty and demanding lifts.
The surface material of grade 100 chains is harder, so you get better abrasion resistance.
Chain Grade | Strength Comparison | Working Load Limit (WLL) | Suitability for Lifting Operations |
|---|---|---|---|
Grade 80 | Standard strength | Lower WLL | General lifting operations |
Grade 100 | Approximately 25% stronger | Higher WLL | Heavy-duty and demanding lifts |
