Working load T8 grade: 2t-175t;S6 grade:0.5t-1250t.
T8 grade is high quality structural alloy steel;S6 grade is structural alloy steel.
The maximum testing load of 0.5t-150t shackle is 2 times of the working load,
the maximum testing load 200t of 500t shackle is 1.5 times of the working load.
The maximum testing load of 800t-12500t shackle is 1.33 times of the working load, the minimum breaking load is 1.5 times of the working load.
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 capacity of 110t,T8 grade is 16%-29% up higher than the S6 grade in the same dimension.
The shackle of 0.5t-175t in accordance with the technical requirements and testing methods of ISO2415-2004.
We designed the 200t-1250t according to JB8112-1999 and the preformance met or exceed the requirements in ASME.B.30.26
shackle and chain assembly with common link,end link etc which is used to chain frontal frames and breasting dolphins or mooring buoys as customers requirements
