Crosby Shackle - Screw Pin Chain Type - Capacity: 13,000 lbs - Chain Size: 7/8 inch
Item: Crosby Shackle - Standard - Screw Pin Type Chain (for frequent open/close) - Working Load Limits: 13,000 lbs - For Chain Sizes: 7/8 inch
Manufacturer / Country of Origin: Crosby / USA
Application: Used for general purpose connections of slings, cables, and chains in overhead lifting applications. Used in 'pick and place' applications that require frequent opening and closing.
Description: Outfitted with a screw pin type securement system with a large round body. Constructed of a bow of carbon steel that has been closed die forged then quenched and tempered, with alloy steel pin. The 6 to 1 design factor is the ratio of the minimum breaking strength to the permissible working load. The shackle size, grade, Product Identification Code (PIC for material traceability), and the working load limit is forged into the bow. Approved for use in -40 degrees F to 400 degrees F.
The Crosby Difference: There are many look-a-like Crosby shackles, often found at lower prices and advertised with the same safety standards. Be aware it may refer to safety ratings in effect decades ago. For example, under the same safety standard a decade ago a lifting shackle may be rated to 100% without proof load testing, while today it may be 300% with proof load testing.
Quality Standard: Meets or exceed the requirements of ASME B30.26, which include identification, durability, design factor, proof load, and temperature requirements. Also go above and beyond these standard safety requirements by including fatigue life, impact properties, and material traceability; factors that are not required by ASME B30.26. Meets the Federal Specification RR-C-271G, Type: IVB, Grade A, Class 1, except for those provisions required of the contractor. Type Approval certification in accordance with ABS 2016 Steel Vessel Rules 1-1-17.7. *NOTE: All shackles 25 tons and above are equipped with RFID (radio frequency I.D.).
Availability: Shipping time is subject to change PER manufacturer availability.
Industry Names: Also known as 'screw pin type chain shackles', or 'screw pin type bow shackles'.
Includes: (1) one Crosby shackle
WARNING: Can be used in applications involving side loading, however this reduces the working load limit. During use, assure that the pin is not allowed to rotate as this may open the shackle. When picking and placing a load, tighten pin prior to each lift. Do not exceed rated capacity!
