Load diagram

Safety factor 4:1

Working Environment Authority provides *) that by asymmetric loads must following be observed: 2-leg chain is calculated as similar 1-leg chain, 3- and 4-leg is calculated as similar 2-leg. By symmetrical lift with 3- and 4-leg can load weight divided by 1 / 3 per. leg.

*) It is in this context, WEA's view that the load is asymmetric unless it can be documented that it is even / symmetrical divided.

Working angles above 60 ° is NOT allowed - Danløft steel chains have a full load capacity between - 40C grades and + 200C grades
