The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).
As the Grade Increases:
| Grade | Material | Primary Applications | Overhead Lift? |
|---|---|---|---|
| Grade 30 (Proof Coil) |
Low Carbon Steel | Light duty, logging, playground equipment, simple barriers. | NO |
| Grade 43 (High Test) |
Carbon Steel | Towing, general utility, load securement. Stronger than G30. | NO |
| Grade 70 (Transport) |
Heat-Treated Carbon | Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish. | NO |
| Grade 80 (Alloy) |
Alloy Steel | Standard Lifting Slings. High ductility (stretch) to absorb shock. | YES |
| Grade 100 (Premium) |
Alloy Steel | Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance. | YES |
Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:
A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.
Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.
Alloy chain is tough, but not invincible. Proper storage and inspection are vital.
EN 818-4 - Safety Requirements for Lifting Accessories
The Machinery Directive stipulates that where chain with welded links is used for lifting accessories it is to be of short line type and for the purposes of this standard this is chain having a ratio of nominal pitch to nominal size of 3:1.
This European Standard specifies the requirements related to safety, methods of rating and testing of single-, two-, three-, four-leg and endless chain slings assembled by:
using short link grade 8 medium tolerance lifting chain conforming to EN 818-2 together with the appropriate range of components of the same grade.
