Key Features of Type B Swivel Shackle
Simplified Connection Design: OLIPORTS’ Type B Swivel Shackle eliminates the need for anchor crown shackles, anchor-end D-shackles, and swivel front sections. This reduces the number of components in the anchor chain assembly by 30%, shortens installation time, and minimizes potential failure points.
Grade 3 High-Strength Construction: Manufactured to Grade 3 marine standards, our Type B Swivel Shackles offer exceptional tensile strength and fatigue resistance, making them ideal for heavy-duty mooring and anchoring applications in harsh marine environments.
Precision-Machined Dimensions: Each swivel assembly is precision-machined to ensure perfect compatibility with standard anchor shanks and anchor chains ranging from 40 mm to 81 mm in diameter.
Corrosion-Resistant Surface Treatment: All OLIPORTS anchor chain swivel shackle are hot-dip galvanized to provide long-lasting protection against saltwater corrosion and rust.
Installation Instructions & Diagram of Type B Swivel Shackle
The OLIPORTS Type B Swivel Shackle features a simple two-pin installation process that standard crew members can complete without specialized tools:
- Align the large pin hole on the Type B swivel shackle with the anchor handle hole
- Insert the large pin through the swivel shackle and anchor handle
- Align the small pin hole with the first standard link of the anchor chain
- Insert the small pin and secure both pins with the included retaining ring
This direct-connect design requires no additional components and reduces installation time by 50% compared to traditional anchor chain assemblies
Applications of Type B Swivel Shackle
OLIPORTS’ heavy-duty swivel shackles are designed exclusively for anchor and anchor chain applications. Their core applications span marine, mooring, lifting, and towing. As a premium marine fitting, it effectively prevents damage to anchor chains caused by twisting during deployment and retrieval. We also offer highly corrosion-resistant stainless steel swivel shackles for anchors, which are particularly suitable for long-term operation in seawater environments.
