Product Description
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.
- Carbon steel/alloy steel die forging.
- S(6) full specification and T(8) full specification undergo CNC furnace heat treatment.
- Manufacture with a tensile test at twice the rated load.
- Conduct a fracture test using sampling.
- Magnetic particle inspection.
- The breaking tensile strength is four times the rated load.
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 processes. Common grades include:
S(6) Grade: Manufactured 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.
Different-grade products offer users a variety of choices for scenarios with varying load requirements.
III. 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: Molding is carried out using precision forging, followed by heat treatment, aiming to enhance the product's overall mechanical properties.
Surface treatment typically involves processes such as galvanizing (hot-dip or electroplating) and painting, which 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.
IV. 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
Construction Engineering Support Operations
