Bolt Type Shackle Application:

• Lifting & Hoisting: Ideal for overhead lifting with cranes, hoists and gantries; used to attach slings, beams and lifting frames.

• Rigging & Winching: Connects winch lines, snatch blocks and hauling assemblies in marine, forestry and mining operations.

• Load‐Securing & Tie‐Downs: Secures cargo on trucks, trailers and flat racks; commonly used with ratchet straps and chains.

• Marine & Offshore: Corrosion-resistant versions for mooring, anchor lines and deck rigging; withstands saltwater environments.

• Construction & Infrastructure: Attaches formwork, scaffolding and temporary structures; used in bridge and tunnel projects.

Bolt-Type Shackle Material:

• Alloy Steel (Grade 80 / Grade 100): Provides high strength-to-weight ratio for heavy-duty lifting; heat-treated for superior toughness.

• Carbon Steel (Galvanized or Painted): Economical choice for general lifting and tie-down applications; zinc coating offers moderate corrosion resistance.

• Stainless Steel (AISI 316 / AISI 304): Excellent resistance to rust and chemical exposure; ideal for marine, food‐processing and pharmaceutical environments.

• Special Coatings: Available with hot‐dip galvanization, black oxide or custom powder coatings for enhanced durability in harsh conditions.

Bolt-Type Shackle Specifications:

Selecting the correct bolt-type shackle is vital for ensuring your load is handled with maximum safety and efficiency. Keep the following factors in mind when making your choice:

• Rated Load Capacity
  Match the shackle’s Working Load Limit (WLL) to the weight of the load you intend to lift or secure. Never exceed this rating to maintain a safe margin.

• Construction Material
  The shackle’s material determines its strength, longevity, and resistance to environmental factors. Opt for carbon steel, alloy steel, stainless steel, or specialized coatings based on your operating conditions.

• Form Factor & Classification
  Bolt-type shackles are available in Dee (D-shackle) and Bow (anchor-shackle) profiles. Select the shape that best accommodates your rigging geometry and multi-leg slings.

• Pin Gauge
  The diameter of the bolt pin influences the overall strength and Rated Load Capacity. Choose a pin size that aligns with your shackle’s WLL and the demands of your application.

• Bow Span
  Measured between the inner faces of the shackle’s arms, the bow span varies by size and WLL. Ensure sufficient clearance for sling legs or attachments to eliminate binding.

• Fastening Mechanism
  While most bolt-type shackles feature a bolt-and-nut with cotter pin, options like screw-pin or round-pin closures are available. Pick the pin style that offers the quickest installation or the greatest security for your workflow.

• Bow Profile
  Shackles may sport different curvature profiles—commonly “U-shaped” or fully rounded “O-shaped” bows. The chosen profile affects load distribution and side-load performance.

• Inner Jaw Width
  This is the distance between the insides of the two arms. Verify that your lifting accessories fit comfortably within the shackle’s throat without excessive play.

• Safety & Compliance
  Always review and adhere to the manufacturer’s usage guidelines and inspection intervals. Confirm that your shackle meets relevant standards (e.g., EN 13889, ASME B30.26) and carries the appropriate proof-load and ultimate-load safety factors.
