Overview: This document provides technical specifications for Double Swivel Shackles (DSS) with both metric and UNC threads. It includes detailed measurements, weight limits, and torque requirements for various models.
Specifications:- Metric Threads: The document lists multiple DSS models with metric threads, specifying the reference diameter, safety factor (SF) 5:1 and 4:1 working load limits (WLL) in tons, standard length (L1), torque in Nm, and various dimensional measurements (A, B, C, D, E, F, G) in millimeters. The weight of each model is provided in kilograms and pounds.
- UNC Threads: Similar details are provided for DSS models with UNC threads, including reference diameter, SF 5:1 and 4:1 WLL in pounds, standard length (L1), torque in ft-lb, and dimensions in millimeters. The weight is also listed in kilograms and pounds.
Key Parameters:- Safety Factor (SF): Two safety factors are considered, 5:1 and 4:1, indicating the ratio of the breaking load to the working load limit.
- Torque Requirements: Torque values are specified for each model, indicating the force needed to secure the shackle properly.
- Dimensional Measurements: Detailed dimensions (A, B, C, D, E, F, G) are provided to ensure compatibility and proper installation.
Recommendations:- Ensure the correct model is selected based on the required load capacity and thread type.
- Follow the specified torque requirements to maintain safety and performance.
- Consider the dimensional measurements for compatibility with existing systems.
