Overview of Shackles
Shackles are a common type of connecting component in the field of lifting slings and rigging, widely used in industries such as ports, power generation, metallurgy, and shipbuilding. Their primary function is to safely and efficiently link components like wire ropes, lifting straps, and hooks, enabling the formation of a complete lifting system.

I. Product Types and Features
Based on their structural design and features, shackles can be categorized into various types to meet different operational needs.
- Arch-type shackle
The loop features a U-shaped or arc-shaped design, offering relatively ample lateral internal space. This design helps minimize friction and wear on the rope when multiple limbs are connected, making it ideal for applications where some room for movement is required.
- D-Type Shackle
The ring features a straight edge on one side, giving it an overall D-shaped profile. Its structural design ensures relatively uniform load distribution, enabling it to deliver a comparatively high load-bearing capacity under the same specifications. It is commonly used for direct connections in single-leg slings.
- Cross-pin type
Bolt-type shackle: The cross pin is connected to the body via threads, resulting in a relatively compact structure.
Pin-type shackles: The cross pin is secured by a retaining pin (such as a spring pin or screw pin), making assembly and disassembly particularly convenient.
II. Product Strength Grade
Shackles come in different strength grades depending on their manufacturing material and heat treatment process. Common grades include:
- S(6) Grade: Made from high-strength alloy steel, it demonstrates excellent load-bearing performance under various operating conditions.
- T(8) grade: Made from alloy steel and processed using a specific technique, this grade offers superior strength compared to the S(6) grade, enabling it to withstand relatively higher working loads at the same dimensions.
- G209, G210, G2130, G2150: These are model codes that meet specific standards (such as U.S. standards), and typically correspond to different strength grades and specification sizes as well.
Different-grade products offer users a variety of choices for scenarios with varying load requirements.
3. Product Design and Manufacturing
Our shackle products emphasize the following aspects during the design and manufacturing process:
Material Selection: Primarily uses high-quality alloy steel, with material properties meeting the requirements of relevant standards.
Process Control: The product is formed using a forging process and undergoes heat treatment to enhance its overall mechanical properties.
Surface treatment typically includes galvanizing (hot-dip or electroplating), painting, and other processes to enhance the product's corrosion resistance and extend its service life.
Quality Control: The production process includes multiple inspection procedures to ensure the stability of product dimensions and performance.
4. Recommended Application Scenarios
Shackles can be used in, but are not limited to, the following operational scenarios:
Equipment Lifting and Handling
Port vessel loading and unloading
Electrical Facility Installation and Maintenance
