Lifting D Shackle – Dee (Chain) Shackles

What is a D Shackle?

Premium Lifting D shackle (Dee or Chain Shackles) are forged from high-grade alloy steel, providing exceptional strength and durability for heavy-duty lifting. With sizes from 0.5t to 85t and safety factors up to 6:1, they ensure secure connections in construction, industrial hoisting, marine, and rigging applications.

Key Features of Our Dee Shackle

1. Premium Material & Forging: High-quality alloy steel body and pin, die-forged for exceptional strength and toughness.
2. Wide Working Load Range: From 0.5 tons (light-duty) to 85 tons (heavy industrial), covering almost all rigging requirements.
3. High Safety Factor: Standard 4:1 or optional 6:1 — every lifting d shackle is load-tested for peace of mind.
4. Corrosion Protection: Multiple surface options (hot-dip galvanized for marine/outdoor use, painted for indoor) extend service life.
5. Traceability & Compliance: Permanently marked with size, WLL, batch code, and standards.
6. Customization Support: OEM/ODM available — special sizes, markings, or finishes for export projects.

Types Of Dee Shackles

1. Screw Pin D Shackle

• Features a fully threaded pin that screws directly into the body for fast, tool-free installation and removal.
• Ideal for applications requiring frequent connection and disconnection, such as temporary rigging setups or daily jobsite use.
• Quick and convenient, yet secure when properly tightened — a popular choice for general-purpose chain shackles.

2. Bolt & Nut Dee Shackle (Safety Bolt Type)

• Uses a bolt secured with a nut and cotter pin (or hairpin) to lock the assembly permanently.
• Provides maximum resistance to vibration, accidental loosening, or rotation under load — essential for long-term or critical lifts.
• Recommended for permanent installations, overhead lifting, or high-risk environments where safety is non-negotiable.

Both types forged from high-grade alloy steel, proof-tested at 2× WLL, and finished with hot-dip galvanizing, painting, or dip coating for corrosion resistance.

Chain Shackle Applications – Where Dee Shackles Excel

Lifting d shackles (chain shackles) are versatile connectors trusted in straight-pull scenarios across industries:

• Connecting lifting chains, wire ropes, or synthetic slings in single-leg hoisting setups
• Rigging and hoisting equipment on construction sites and civil engineering projects
• Securing and lifting heavy machinery in factories and warehouses
• Marine and offshore applications — boat mooring, anchor connections, deck hardware
• Industrial maintenance, recovery operations, and load securing tasks

Because of their narrow profile and high in-line strength, dee shackles outperform wider types when load alignment is critical and side-loading must be avoided.

How to Choose the Right D Shackle for Your Job?

1. Calculate Your Load → Determine the maximum working load (including dynamic factors). Choose a shackle with WLL at least 1.5–2× your calculated load.
2. Select Closure Type → Screw pin for quick, frequent use; bolt & nut for permanent, vibration-resistant security.
3. Match the Environment → Hot-dip galvanized for outdoor, marine, or corrosive conditions; painted for indoor or aesthetic needs.
4. Check Pin & Body Fit → Ensure pin diameter matches your chain/sling/eye bolt; never force-fit components.
5. Verify Standards & Inspection → Confirm compliance markings; always inspect for wear, deformation, or cracks before each use.
6. Avoid Common Mistakes → Never side-load a d shackle (use bow shackle instead for angled pulls); never exceed WLL.
