The anchor swivel is one of the extremely important accessories in the marine transportation industry. But what exactly is a swing shackle, and what comprises an anchor chain set? Let’s explore these questions with CAPVINA in the article below!

What is the anchor swivel?

Anchor chain rotation is a specialized mechanism designed to prevent the twisting of the anchor chain. It is typically connected to the second or third level of the anchor chain.

The anchor swivel is constructed from steel and features a hot-dip galvanized surface for enhanced durability. Swivels are available in various sizes to accommodate the unique requirements of our customers.

These swivels are commonly installed between the anchor and the chain cable to prevent twisting and kinking of the chain cable. They are available in sizes ranging from 6mm to 16mm.

Structure of anchor swivel

Anchor swivels come in two common types, each with a distinct structure. Let’s delve into the details of these types and their respective structures below.

• A 5-piece swivel shackle consists of the following components: 1 figure-8 swivel cup, 1 sewing link, and 2 chain links with brackets. These components collectively serve.
• A 3-piece swivel shackle comprises 1 figure-8 swivel cup and 2 sewing eyes, each with its unique role

The anchor swivel is crafted from high-tech cast steel, often sourced from overseas. Its notable feature is its ability to rotate a full 360°, preventing the twisting of the chain and potential damage to the ship’s mooring chain.

This device is commonly employed to connect between a chain link and the anchor chain within the matrosov anchor chain of the chain winch system. This not only helps in cost-saving but also simplifies chain maintenance procedures.

Characteristics of swivel shackle

• Anchor swivels serve as a crucial link in creating a complete set of ship anchor chains. They play a vital role in preventing the chain from rotating, which can lead to chain breakage or damage to other connection points.
• These swivels are known for their high durability, ensuring they meet design and technical requirements. They find frequent use in the maritime industry, serving applications such as anchoring buoys, ship anchors, offshore platform anchoring, and various types of ship anchor chains.
• For custom designs, we offer CO (Certificate of Origin), CQ (Certificate of Quality), Mill Cert, and Third-Party CCS/LR certifications (Original) to guarantee compliance with design drawings.

What is an anchor chain swivel?

The anchor chain swivel, often referred to as a swivel shackle, is a popular rotating link used in boats.

Our swivel forerunners are manufactured in compliance with ISO 1704 standards and are available in alloy steel, or stainless steel, with diameters ranging from 12.5 mm to 162 mm. Surface options include black paint, hot-dip galvanization, and electro-galvanization. We offer customized solutions to meet the diverse needs of our customers.

This versatile swivel connector is widely used for deploying and retrieving anchors. It serves as a connection between the anchor chain and the end shackle. The anchor face is open for the installation of anchor shackles. While the other side features a common link for Kenter shackle installation. It is suitable for use with level 2 and level 3 anchor chains and provides a cost-effective and safe solution for chain accessories.

Tips for using rotating shackles effectively

The swivel serves as the weakest link in the connection between the anchor and the ship. For example, if the anchor becomes entangled with a rock or boulder, the swivel shackle may enter the anchor shaft or shift to the side, resulting in load value discrepancies compared to the previously calculated SWL (Safe Working Load). To prevent these occurrences, it’s essential to install the shackle in a manner that prevents side loading.

One effective tip to avoid spindle jamming is to use a short chain. The short chain is connected to the anchor using shackles, and a coupling is then attached between the chains.

Before purchasing this tool, ensure that the SWL rotation value matches the chain you intend to use. Additionally, match the swivel material to the chain material; for example, if you are using galvanized chain, opt for a galvanized swivel chain.
