Features

Working Load Limit permanently shown on every shackle.
Forged - Quenched and Tempered, with alloy pins.
Capacities1 ton to 150 tons.
Shackles 55 tons and smaller can be can be furnished proof tested with certificates to designated standards, such as ABS, DNV, Lloyds, or other certification.
Material Certification (Chemical) must be requested at the time of order.
Made from SAE 8620

	Shackles symmetrically loaded with two leg slings having a maximum included angle of 120 can be utilized to full Working Load Limit.
Angle loads must be applied in the plane of the bow	Never exceed 120 included angle. Use Bolt Type and Screw Pin Shackles Only

Side Loading reduction Chart For Screw Pin & Bolt Type Shackles Only
Angle of Side load from vertical in line of shackle	Adjusted WLL
0^o In Line	100% of Rated WLL
45^oFrom In Line	70% of Rated WLL
90^oFrom In Line	50% of Rated WLL

Note

Maximum Proof Load is 2 times the Working Load Limit. Minimum Ultimate Load is 5 times the
Working Load Limit.

Note

The pin diameters actually used may be based on any standard series for sizes of bar material provided that the intervals between adjacent sizes do not exceed the R20 Interval (1.12) The next size above the minimum pin diameter, D min as given in the above table should be used. The Nominal diameter D used is then subject to the tolerances specified in 5.2 of IS:6132 (Part I). 1971 The eye outside diameter then becomes twice the nominal Pin Diameter D subject to the tolerances in 5.2 of IS:6132 (Part II) - 1971.

Specification for Shackles : Part I General Requirement for grade 30, 40, and 63 only.
Shackles of Grade 30, 40, 63 confirm to I.S.I specification 6132
