3-Leg Wire Rope Sling with Bolt-Type Bow Shackles – Built for Rugged Lifting

3-Leg Wire Rope Sling with Bolt-Type Bow Shackles: When it comes to heavy, rugged lifting operations, safety, strength, and reliability are non-negotiable. Industries such as oil and gas, marine logistics, construction, and heavy manufacturing require lifting solutions that are built to perform under stress. One such trusted rigging solution is the 3-leg wire rope sling with bolt-type bow shackles.

At SSTC (Safe and Secure Trading Company), a leading provider of lifting equipment in Saudi Arabia, we deliver certified, high-quality rigging tools that can handle the harshest working environments. In this blog, we explore the features, advantages, applications, and safety of 3-leg wire rope slings with bolt-type bow shackles—a combination engineered for rugged and secure lifting.

What is a 3-Leg Wire Rope Sling?

A 3-leg wire rope sling is a multi-leg lifting assembly comprising:

• A master link or ring for crane attachment
• Three wire rope legs evenly spaced from the master link
• End fittings, such as hooks or shackles

This configuration is ideal for lifting irregular, asymmetrical, or multi-point loads where stability and even load distribution are critical.

What Are Bolt-Type Bow Shackles?

Bow shackles, sometimes called anchor shackles, feature a wide “O”-shaped bow that allows for multi-directional loading. The bolt-type design includes:

• A threaded bolt
• Nut
• Cotter pin

This setup ensures permanent and secure fastening, reducing the risk of accidental disengagement during dynamic or long-term lifts.

Key Benefits:

• Superior for multi-leg sling assemblies
• Excellent for rotating or shifting loads
• Highly secure—ideal for long-duration lifts
• Reduces the risk of loosening under vibration

Advantages of 3-Leg Slings with Bolt-Type Bow Shackles

1. Enhanced Load Stability

The three-leg design ensures better balance during lifts, even with irregular or imbalanced loads.

2. Increased Load Capacity

Distributing the weight across three wire rope legs allows the sling to handle higher loads safely.

3. Superior Safety with Bolt-Type Shackles

Bolt-type shackles are secured with a nut and cotter pin, ensuring the connection stays locked—ideal for long-duration or critical lifts.

4. Multi-Directional Load Support

Bow shackles accommodate angular pulls better than D-shackles, making them suitable for complex rigging setups.

5. Long Service Life

Galvanized wire ropes resist corrosion, and the shackles are treated for maximum durability in harsh environments.

Safety & Inspection Tips

At SSTC, we recommend the following safety practices:

Pre-Lift Checks

• Inspect for broken wires, corrosion, bird-caging, or kinks in the wire rope
• Confirm shackles are free of cracks, deformation, or excessive wear
• Ensure bolt, nut, and cotter pin are properly secured

Avoid These

• Shock loading
• Side loading the shackle
• Using slings below their rated sling angle
• Lifting with a damaged or uncertified assembly
