Product Description

 JIS Standard Free Forged Alloy Steel Bow Shackle for Lifting/Lashing/Marine Riggings/Floating Pontoon/Fender System

 

Shackles are essential components in the field of rigging and lifting, widely used in industries such as marine, construction, and transportation. They serve as critical connectors in lifting systems, enabling the secure attachment of loads to lifting equipment. Among the various types of shackles, Bow Shackle and Dee Shackle are the most commonly used. 

A shackle is a U-shaped or D-shaped metal component that is secured with a pin or bolt. It is primarily used in rigging systems to connect loads to lifting appliances such as cranes, winches, and hoists. Shackles are also used in padlocks and carabiners in mountaineering and climbing applications. The two main types of shackles are:

• Bow Shackle (Anchor Shackle): Has a larger, round "O" shaped bow, allowing for side loading and multiple sling-leg connections.
• Dee Shackle (Chain Shackle): Has a narrower D-shaped bow, designed for in-line tension and should not be side loaded.

Shackles are categorized based on their material, finish, safety factor, and standard compliance. Common materials include carbon steel, alloy steel, stainless steel, and galvanized steel. The safety factor is typically 4 to 8 times the Working Load Limit (WLL), depending on the application and standard.

 

A dee shackle is a U-shaped or D-shaped metal component with a narrower D-shaped bow. It is designed for in-line tension and is not suitable for side loading. The dee is the curved portion of the shackle, and the eyes are the parts that support the pin. The pin is a steel bolt that passes through the eyes of the shackle.Dee shackles are available in various sizes, ranging from 3/16" to 3", and are categorized into US Standard, JIS Standard, and European Standard. The Forged and Free Forged specifications are commonly used in industrial applications.

• US Standard: Dee shackles are manufactured to US Fed Spec RR-C-271 and are available in Grade 8 and Grade 10.
• JIS Standard: Dee shackles are manufactured to JIS B 2001 and are available in Grade 8 and Grade 10.
• European Standard: Dee shackles are manufactured to EN 13889 and are available in Grade 6, Grade 8, and Grade 10.

Advantages

• High Strength-to-Weight Ratio: Dee shackles are designed to handle high tensile loads and are suitable for heavy lifting applications.
• Durability: Made from high-strength steel, dee shackles are resistant to corrosion and wear, especially when galvanized or stainless steel is used.
• Safety Features: Many dee shackles are equipped with safety bolts and split pins to prevent accidental disengagement.
• Compatibility: Dee shackles are compatible with standard lifting equipment and can be used in conjunction with other lifting accessories.
