Enhanced security

The inner hexagon pin design provides a secure and tight fit, reducing the risk of accidental loosening.

Ease of use

The design allows for easy installation and removal using standard tools, making it a practical and user-friendly solution.

Types of Shackle

01/

D shackles: Most commonly used on single-leg slings, D shackles (or dee shackles) - as the name suggests - are shaped like the letter D. They also resemble a loop of a chain, which explains why they are sometimes referred to as 'chain shackles'.

02/

Stainless steel shackles: Extremely durable and long-lasting, our stainless steel shackles are the ideal connection for use in tough conditions, making them the perfect fastening mechanism for sailing and industrial rigging jobs.

03/

Safety pin shackles: Designed for maximum security, safety and reliability, these shackles use a nut and bolt, with a safety pin providing further stability and assurance. This particular fastening option is a popular choice for many lifting firms, including some of the leading lifting rental companies in the UK.

04/

Screw pin shackles: Primarily used for temporary applications, screw pin products are great for jobs where shackles regularly need to be removed and re-attached. When using screw pin shackles, it's important to remember to check the pin prior to each lift and re-tighten if necessary.

05/

Green pin shackles: One of the most popular lifting shackle types in our range, our green pin shackles are essentially alloy bow shackles, providing durable reliability in eye-catching green for heightened visibility and easy identification.

06/

Bow shackles: Recognisable by their 'O' shape, bow shackles are commonly used on multi-leg slings. Ideal for jobs such as rigging, bow shackles provide an easy way of fastening chains and straps securely. These shackles come with a variety of weight limits and in a range of colours, which can be particularly useful for live event rigging where black shackles can minimise their visibility.

Key Features of Shackle

Material: Constructed from 304 or 316 stainless steel, this d shackle provides outstanding resistance to rust, corrosion, and pitting. The 316 stainless steel variant offers superior protection against saltwater and other corrosive elements, making it especially suitable for marine and offshore applications. The 304 stainless steel option is highly durable and resistant to oxidation, making it ideal for industrial and general-purpose use.

Inner hexagon pin: The d shackle features an inner hexagon pin, which allows for easy installation and removal using standard tools like wrenches. The hexagon design ensures a secure, tight fit, preventing the pin from loosening during operation. This feature also enhances the overall safety and reliability of the shackle, providing better control over load handling.

Shape and design: The d shackle has a "d" shape, offering superior load distribution and strength. The design allows for the shackle to be easily attached to chains, ropes, or other rigging components, making it a versatile solution for a wide range of applications.

Finish: The polished finish of the stainless steel gives the shackle an attractive appearance, while also reducing the likelihood of rope abrasion and wear. The smooth surface prevents snagging, ensuring that the connected materials are handled safely and efficiently.

Production Process of Shackle

Cutting: We use the cold cutting by type shears to the whole round steel into pieces, no matter what size you want to produce such as 3/8 inch shackle, 1/2 inch shackle, 5/8 inch shackle, 3/4 inch shackle, or even 4 inch shackle, we should make sure the round steel pieces length is at least two times of shackles body length. Roll forging and punching bending are also the very important processes, for heating the shackle and hammering it into shape to creates the desired steel grain structure.

In the process goes into making these shackles, dia forging and heat treatment steps are the key points, after dia forging, all load rated shackles structure has become more compact, and the plastic and mechanical properties of the shackle rating have been improved. Heat treatment also known as quenched and tempered, makes the shackles have a high fatigue resistance and allows the shackle body and pin to bend before breaking, not to brittle fracture, keep the load rating safe, keep the required temperature and time on auto-continuous heat treatment furnace, then you can get the high strength shackles featured 6times.

Edge cutting, burr removing, drilling, tapping, and thread rolling steps make the shackles surface more smooth, and prepare for the next process surface finishing. Surface treatment can offer excellent protection from rust and corrosion for rigging shackles.

FAQ

Q: What is a D shackle?

A: D-shackles also referred to as 'Dee-shackles', are narrow shackles shaped like a loop of chain. They are usually closed with a threaded pin or a clevis-type pin, and they're generally seen as suitable choices for moderate to heavy loads that are being lifted in line.

Q: What is the difference between a bow shackle and a D shackle?

A: “D” (chain) shackles are generally used to join two pieces rated for in-line tension, while bow (anchor) shackles are typically employed where more than one attachment has to be made to the body, for side and racking loads may twist or bend the chain shackle.

Q: When to use d-shackle?

A: Bow shackles are commonly employed in rigging systems where multiple ropes, slings, or chains need to be hooked up. Conversely, D shackles are frequently used in towing operations, industrial lifting, and anywhere a robust, single-direction force is the order of the day.

Q: What is another name for D shackle?

A: D-shackle. Also known as a chain shackle, D-shackles are narrow shackles shaped like a loop of chain, usually with a pin or threaded pin closure. D-shackles are very common and most other shackle types are a variation of the D-shackle.

Q: What is the difference between a Kenter shackle and a D shackle?

A: 'D' Type Joining Shackles – These are designed to allow connection between two studless end links of anchor chain. Unlike the Kenter Link, 'D' Type Joining Shackles do not fit the gypsy. The 'D' lugged joining shackle is used extensively for joining the chain to the anchor in more modern vessels.

Q: What is the correct use of D shackle?

A: Dee shackles are intended for straight in-line lifting. This is why it's important to position the load correctly. Its centre line needs to coincide perfectly with the centre line of the shackle's body – therefore avoiding a side bending load and improving the overall efficacy of the equipment.

Q: What is the code for D-shackles?

A: The specific HSN code for d shackle depends on the product type. Seair is proficient in interpreting HS code 5201 for d shackle products and assisting you through the complexity of customs guidelines.

Q: How do I choose a shackle size?

A: Always ensure that the selected shackle meets or exceeds the working load limit for each specific task and is comparable to the Working Load Limit (WLL) of other rigging hardware being used in the lift or suspension.
