2. Lifting capacity EN 818-6 - 4, Grade 4

In comparison with grade 2 and Armco the working load limits of grade 4 are much higher. This means a lower chain weight with the same working load limits, because smaller diameters can be used. This is accompanied by a reduction in the chain surface.

EN 818-6 - 4 grade 4, replacement: when the next lowest nominal diameter is reached
