Product Description

Overview of Shackles

Shackles are a common type of connecting component in the lifting and rigging industry, widely used across sectors such as ports, power generation, metallurgy, and shipbuilding. Their primary function is to safely and efficiently link components like wire ropes, slings, and hooks, enabling the creation 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.

Bow-type shackle

The loop features a U-shaped or arc-shaped design, providing relatively ample lateral internal space. This design helps minimize compression and abrasion of the rope when multiple limbs are connected, making it ideal for applications where some room for movement is required.

Type D Shackle

The ring features a straight edge on one side, giving it an overall D-shaped profile. Its structural design ensures a more uniform distribution of load, enabling relatively high load-bearing capacity at the same specifications—making it commonly used for direct connections in single-leg slings.

Cross-pin type

Bolt-type shackle: The cross pin is connected to the body via threading, resulting in a relatively compact design.

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.

2. 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, allowing 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 they typically correspond to different strength grades and specification sizes as well.

Different product tiers offer users a diverse range of options 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 high-quality alloy steel is used, ensuring that material properties meet the relevant standard requirements.

Process Control: The product is formed using a forging process and subsequently undergoes heat treatment, aiming 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 steps to ensure consistent product dimensions and performance.
