Overview: This document provides technical specifications for the Double Swivel Shackle designed for offshore applications and external use. It includes details on metric and UNC threads, load capacities, and dimensions.
Specifications:- Safety Factor (SF): The shackles have a safety factor of 5:1 and 4:1, indicating the ratio of the breaking load to the working load limit (WLL).
- Working Load Limit (WLL): The WLL varies depending on the reference diameter and safety factor, with values provided in both metric tons and pounds.
- Dimensions: Key dimensions such as L1, S, A, B, C, D, E, F, and G are specified in millimeters.
- Torque: Torque values are provided in Newton-meters (Nm) and foot-pounds (ft-lb) for different shackle sizes.
- Weight: The weight of the shackles is listed in kilograms and pounds.
Key Data from Tables:- For metric threads, the reference diameters range from M24 to M42, with corresponding WLLs from 4.50 to 15.00 metric tons (SF 5:1) and 5.50 to 15.00 metric tons (SF 4:1).
- For UNC threads, the reference diameters range from 1’’-8 to 1" 3/4-5, with corresponding WLLs from 10,000 to 33,000 pounds (SF 5:1) and 13,000 to 33,000 pounds (SF 4:1).
Applications: These shackles are suitable for offshore and external applications, ensuring high safety and reliability under demanding conditions.
