It is made of high quality alloy steel by die forging.

Each shackle will be marked with WLL permanently, WLL from 2t~175t.

The maximum testing load is twice of the working load, the minimum breaking load is 4 times of the WLL.

About the bearing capacity of 2t~80t, T8 grade is 40%~100% up higher than the S6 grade in the same dimension. About the bearing of 110t~175t, T8 grade is 16%~29% up higher than the S6 grade in the same dimension.

Our products all correspond with stipulated technical requirement and rest approach in standard ISO2415-2004.

With the same working load capacity, T8 products are smaller than S6, which enables T8 to be mainly employed in limited space.
