Bolt Type Anchor Shackle
A bolt-type anchor shackle is a highly secure and robust rigging component used to create stable connections between lines, cables, or other lifting components and an object. The design consists of a bolt that passes through a loop or ring, secured with a nut on the opposite side. This bolted connection ensures a tight and reliable fit, preventing any accidental loosening, even under heavy loads or extreme stress. The bolted design provides an additional layer of security over screw pin shackles, making it ideal for applications where strength, reliability, and safety are paramount.
Bolt-type anchor shackles are commonly found in construction, marine, and heavy-duty rigging industries, where high loads and harsh operating conditions require secure, long-lasting connections. These shackles excel in rigging operations that involve lifting, securing, or towing heavy equipment, machinery, or materials. The bolted design makes them particularly useful in applications that demand stability and durability, ensuring that the connection remains intact and functional even in high-stress environments such as offshore rigs, crane operations, and large-scale construction projects.
Key Features and Benefits:
- High Security – The bolted connection between the pin and the shackle body provides a secure and stable connection, minimizing the risk of accidental loosening. This makes bolt-type anchor shackles ideal for applications where safety and reliability are critical.
- Heavy Load Capacity – Bolt-type anchor shackles are designed to handle high loads, making them suitable for heavy-duty lifting, rigging, and securing operations in industries such as construction, marine, and offshore oil rigs.
- Durable Construction – Typically made from high-strength steel or alloy steel, these shackles offer excellent resistance to wear, corrosion, and stress, ensuring long-term durability in tough environments.
- Bolted Design – The bolt-and-nut connection offers a tight, reliable fit that doesn’t loosen over time. Unlike screw pin shackles, the bolt-type design ensures a more permanent and secure connection, even under the most demanding conditions.
- Easy to Maintain – The bolt and nut can be easily checked, replaced, or tightened during maintenance, ensuring that the shackle remains in optimal condition over time.
- Versatility – These shackles are highly versatile and can be used in various rigging configurations, such as connecting lifting slings, chains, towing lines, and more. Their ability to work with a variety of components makes them suitable for different industries and applications.
Common Applications:
- Electrical and Power Industry – These shackles are used to lift and secure electrical cables, transformers, and other large equipment in the power generation and distribution sector. The reliable, high-capacity connection ensures safe handling of sensitive or heavy components.
- Entertainment Rigging – In the entertainment industry, bolt-type shackles are used for rigging heavy lighting, sound equipment, and stage structures. Their secure connection is vital for ensuring safety during performances and installations.
- Aviation and Aerospace – These shackles can be used in the aviation industry to secure loads during aircraft transportation or rigging of parts. Their strength and durability are essential for handling high-stress environments.
- Mining Industry – In mining operations, bolt-type anchor shackles are used to secure and lift mining equipment and materials. The robust design of these shackles makes them well-suited for use in abrasive environments where high strength and reliability are critical.
- Towing and Securing – Bolt-type anchor shackles are used in towing operations, such as hauling large vehicles, boats, or containers. The secure connection provided by the bolt ensures that the load stays attached even under the stress of movement.
- Heavy Lifting Operations – Bolt-type shackles are commonly employed in heavy lifting operations, such as using cranes to lift machinery, vehicles, and industrial equipment. Their reliable fastening ensures the equipment is securely connected during the lift.
- Oil and Gas – In the offshore oil and gas industry, bolt-type anchor shackles are used for lifting heavy equipment, securing pipes, and mooring platforms. The high load capacity and secure fastening are crucial for safety in these demanding environments.
- Marine and Offshore – These shackles are widely used in the marine industry for mooring ships, securing anchor chains, and connecting marine rigging equipment. Their corrosion-resistant properties make them suitable for saltwater environments, ensuring durability under harsh conditions.
- Construction Rigging – Bolt-type anchor shackles are commonly used in construction sites for lifting heavy materials such as steel beams, concrete slabs, and structural components. Their high strength and secure connection make them ideal for ensuring safe and stable lifts.
Why Choose Bolt Type Anchor Shackle:
- Enhanced Security
- High Load Capacity
- Durability and Longevity
- Reliable Connection
- Versatility
- Easy Maintenance
- Long-Term Cost Efficiency
Key Considerations:
- Time-Consuming to Install – The process of tightening the bolt and nut to secure the shackle can be more time-consuming than other types of shackles. This can slow down the rigging process, especially when used in high-volume operations that require quick connections.
- Limited Adjustability – Bolt-type anchor shackles are more rigid compared to alternatives like quick links or adjustable slings, which may limit their flexibility in certain applications. They provide a fixed connection that cannot easily be adjusted once installed.
- Regular Maintenance – Bolt-type shackles require regular inspection and maintenance to ensure the bolt, nut, and threads are in good condition. Over time, wear and tear can occur, and damaged components need to be replaced to maintain the integrity of the connection.
- Not Ideal for Dynamic Loads – While bolt-type shackles are excellent for static loads, they may not be as suitable for applications involving dynamic loads or frequent adjustments. In such cases, other types of shackles or rigging components may be more appropriate.
